I am a user of firefox 3.5 rc and it seems fine to me not sure what the fuss is about it is still in the testing stage I am sure that mozzilla will fix all the bugs. I do trust them far more than microsoft who are slower than glaciers whan it comes to fixing bugs in IE

Vulnerability CVE-2008-0015 was just made public this morning after over a month of active exploitation by the bad guys. The vulnerability targets Active-X video controls in IE 6 and 7, and the CVE id indicates it was reported to Mitre (who maintains the CVE database) on December 13, 2007, making Microsoft's knowledge of the bug at least 18 months in duration.

What kind of bug takes 18 months to fix? 18 months is far slower than a glacier in Internet time.

I'm with Glen. I am sure there are bugs. But I don't think they are much worse or better than average (across all vendors). In other words, par for the course.

I have yet to be bothered by any bugs. On the other hand, I'm very pleased with certain features, including TraceMonkey, native JSON, the VIDEO tag, geo-location, and PrivateBrowsing.

Since upgrading I am getting many Server Not Found errors. It can be when first loading a page, or when a page refreshes itself. This was a small problem with the earlier version, but is now becoming a real pain.

I have had no problems with 3.5. I have installed it on my 3 main PC's I run and have not had any issues of slowness on start-up. I don't use trace-monkey.

You know, if Microsoft had done something like this, the IT press and pundits would be falling over themselves bewailing it and crucifying Microsoft...but because it's Firefox, hardly a whimper of complaint. Very nice balance...

Funny, I do... Microsoft was given a pass on it by the media, and they finally had to do it right with Windows 3.1.

Did they do the right thing and give Windows 3.1 to all those people who bought the buggy and crash-prone Windows 3.0? History holds the answer, as it does for those long suffering Vista users who were given far far less than they were promised.

I sure hope one of the bugs they fix is how long it take to get FF3.5 launched. It a lot slower than both FF3.0x and IE8.

I can't believe anybody but Microsoft would ever release such a piece of GARBAGE as an actual release!

What really pisses me off, is that you can't even roll-back to the old version, you would lose all your bookmarks, passwords, and cookies if you do.

I've quit using FireFox all together, and switched to Google Chrome.

You are wrong as far as rollbacks are concerned.

I took a .exe of Firefox 3.0.8 and installed it over Firefox 3.5 and it completely rolled me back keeping all my bookmarks and Add-ons safe, and then of course I updated to 3.0.11

This is probably the buggiest piece of software I've ever used. The FireFox team has completely ruined it's own credibility by releasing such a piece of GARBAGE. To make it even worse, you can't even roll-back to the previous version without losing your bookmarks, passwords, and cookies!

You are wrong as far as rollbacks are concerned.

I took a .exe of Firefox 3.0.8 and installed it over Firefox 3.5 and it completely rolled me back keeping all my bookmarks and Add-ons safe, and then of course I updated to 3.0.11

You probably should not comment if you've only used one or two pieces of software. No other way can FF4.5 be the buggiest.

I'm also receiving frequent 'Server Not Found' errors messages when trying to load new pages. Worryingly there are reports that FF3.5 has corrupted XP, and impacts on other browsers installed due to the new DNS prefetching.

I often got that with the previous version, click on try again and Bang it's there!

Thought it was the server, as it would happen every third or fourth session. Hmm, so I'm not alone.

Never had 3.5 Crash, suggest you guys clean up the background programs, don't need all that sh*t running.

Obviously something is getting stepped on, in the DOS days always pointed to a DMA problem and probably still does.

Yahoo!Mail Help in an effort to help repair the many features which no longer worked under FireFox 3.5 cancelled my account (deletingin the process >500 e-mail and all my folders).

The Address AutoComplete function in Yahoo!Mail does not work any longer.

An endless series of supposed fixes were suggested by Yahoo!Mail Help Desk. None worked. If I had paid for FireFox 3.5 I would now sue the Mozilla company.

I have found a lot of problems with sites that rely on ActiveX scripts (such as Yahoo! and ESPN) working properly in Mozilla. I fault the website creators, as they chose to use a technology that is proprietary rather than going with open standards. I have the same problems with those sites using Opera.

On the other hand, I have had pretty good luck using a plugin called IETab for Firefox. This fakes the web server into thinking my browser is IE instead, and I have used this to get around a LOT of problems caused by poor website coding. Hopefully IETab has been updated to work with Firefox 3.5...

Actually IE Tab is a plug-in that allows an instance of Internet Explorer to be opened in a Firefox browser tab. This plug-in only works on machines that have IE installed. It does not work and is not available for Linux users.

Maybe it's just your machine. I have had nothing but success with FF3.5 on the 5 machines I have updated so far. It's faster and more stable over long sessions.

I'll take it any day over IE (pick your version) even if there are a few bugs

well, from one Chrome crash in 6 months and 0 IE8 crashes in a few weeks, I returned to the Firefox fold.....to run into *three* crashes inside 24 hours.
Not an impressive release......heading back to IE8 !

Every product's V1 is always somewhat buggy. We had ample warning -- the firefox people had indicated that the javascript engine was a complete rewrite.

I have had two crashes since installing firefox. Both are associated with youtube content, which leads me to believe that the problems are plugin-related. I've enabled the "phone home" bug reporter so they can figure things out.

I gave Microsoft a pass on Windows 3.0 and helpfully gave them lots of bug reports -- but then they charged me for Windows 3.1 (which was indeed what Windows 3.0 should have been), and all that good will evaporated. I'm sure the Firefox people won't make my good will evaporate in quite the same way as Microsoft did back then -- and is about to do again for all us poor suffering Vista users.

Agreed with your comments about version 1 of anything, but having used Vista since early betas, I have loved it. I've loaded Firefox 3.5 and have had it crash many times already, but then, it has been getting a workout on a machine with limited memory (a new netbook on XP). I love the Cool Iris plug-in.

After living with XP on my 17" dual-core dual-disk HP laptop with dedicated "Vista-capable" video adapter for about six months, HP sent me the free Vista upgrade for my machine. Not wanting to "ruin" the machine, I cloned the XP system to the (unused) second hard drive, pulled both drives, installed the second drive into the primary position, and assured myself that the system behaved identically aside from Microsoft's validation requirements [changed HDD equals call to 1-800-ireland "you are trying to pirate windows, aren't you?"] (and assured me that I had a valid backup -- the original XP system disk).

I then installed Vista Ultimate (the replacement from HP) onto the second disk and began using.

The poor machine acted like it had been slapped upside the head. While easily in Vista Ultimate range (4.3), it had much slower performance by my various applications, from photoshop to matlab.

Interestingly, Windows 7RC behaves like XP, so Vista is indeed the slug I think it is, and I will have to go to W7 to get back the power I paid HP to have in my laptop. I'm not the only one who's complained about Vista being a resource hound dog, and I'm sure Microsoft knows exactly what went wrong with Vista -- which is why W7 is faster. But we will have to pay to find out.

I also have had FF3.5 crash twice -- in youtube. So part of the problem appears to be their handling of embedded content via plug-ins.

If Mozilla releases a exploitation alert for the bugs in the new code, I will drop back, but I'm sticking with the beast for the present; I just don't do youtube right now, and I've turned on the bug reporter.

That response from Mozilla is different from yesterday's news of an actively exploited 18-month old bug in the ActiveX handler for IE -- an alert which originally targeted just old IE6/IE7, but has been expanded to IE8. Microsoft's interim fix is to issue kill-bits for targeted ActiveX components, which is a band-aid, not a real fix, since the bad guys just have to find an ActiveX component not in the kill-bit list that they can exploit until Microsoft gets the word and kill-bits the exploited component.

When Mozilla "rushes" to fix bugs, I'm sure they don't mean waiting until after they hear in the news that the bad guys have found and exploited the bug they didn't fix for 17 months (the bug is 18 months old, but has been exploited in the wild for over a month).

I said "Vista Capable" in my previous comment -- what I meant was "Vista Ready" -- I bought a laptop advertised to run the full up Vista including Aero desktop, when it became available.

I'm running XP with 3gb of RAM. I've had nothing but problems with keyboard hanging and crashes with all versions since FF 3.0.7. I just tried 3.5 and couldn't connect to my ISP, and forget about add-ons. I'm now happily back to 3.0.7.

Running XP with 1Gig, no crashes so far but don't run an S-load of programs in the background (can't with a gig).

Is it my imagination or does it seem to take longer to load??

Also can't get the window upon exiting that shows me exactly what I'm erasing as per 3.0.

The bugday was not done “in response” to any feedback. It is part of a larger initiative on the part of the Mozilla QA community to increase community participation in Triage of UNCONFIRMED bugs on the Mozilla bug tracking database, Bugzilla (bugzilla.mozilla.org). This bugday had been planned from before Firefox 3.5 was released, and was originally scheduled for June 30th, but was moved because the release of Firefox 3.5 was scheduled over it. If you read the url in the bugday (http://quality.mozilla.org/events/2009/jun/30/firefox-bugday-catch-missed-blocker-critical-and-major-35-bugs), you can see that June 30 is in it, even though it actually happened on July 7th. This is because we did not want to change the URL after broadcasting it. Also, the original e-mail which I posted on the resuming of bugdays can be found at http://groups.google.com/group/mozilla.dev.quality/browse_thread/thread/acbfe5b45d533ac4#. You can see we did not plan this in response to “complaints”, but before Firefox 3.5 was even released.
You seem to misunderstand the reason for having a bugday. As I touched on earlier, bugdays are for encouraging members of the community to participate in bug triage. Triage is taking a bug reported to Mozilla, making sure it has enough information, ensuring it is in the correct component, and then trying to reproduce the issue. The Mozilla QA site (QMO, quality.mozilla.org), is a great place to learn more about this. Quoting the bugday page:

“During this Bug Day, we will focus on narrowing down unconfirmed bugs to find any important ones that have been reported, looking especially for regressions in Firefox 3.5 that weren't in Firefox 3.0.x. Once we find them they can be assigned to developers to be fixed in a security and stability release (e.g., Firefox 3.5.1).”

During this quarter at Mozilla, we will be focusing on reducing the number of UNCOMFIRMED bugs in Bugzilla, and this was the first part of that effort.
These bugdays are regular events. We have another scheduled for July 14th (http://quality.mozilla.org/events/2009/jul/14/firefox-35-bug-triage), and I invite you to come and join us.

Hi,
to crash FireFox 3.5 you just have to use this script:

<html></html>

Other browsers (Chrome, Safari) execute this script instantly. :-(

This forum doesn't show scripts :-(
Anyway, here's the script:

http://forum.mozillaitalia.org/index.php?topic=39876.msg253167#msg253167

Firefox 3.5 does not let Yahoo Mail close properly. When clicked sign off, a gray screen comes up and the system hangs up. You have to Close the session and restart the browser to do anything. It has happened on my XP machine with 1.5g RAM.

Downloaded release 3.5.1 and still no solution. Then I noticed that I never installed Yahoo add on toolbar and it was automatically showing up since 3.5 initial install. Removed the Yahoo toolbar add on and refreshed browser. It worked and now I can sign off from Yahoo Mail and come back to regular Yahoo environment.

Google Firefox 3.5 and Server Not Found

Therein you'll see how much of a pain FF has become to many, many people.

I have enjoyed every version of FF, but this one is disturbing. I highlight an item and before right-clicking a new window opens or mysteriously or when I have two or three tabs opened it automatically switches to separate windows without me touching it!!!! Memory hog even with all extensions and plug-ins disabled. What happened???? Had to go to Chrome and I hate it!!!

Ok, I must reveal that I'm not a Mirosoft fan - so I use Firefox and up to now its been reasonably good - apart from the zoom which is poor. However the 3.5 and the fix 3.5.something, is less than reliable - crashes, server not found, pages not displaying correctly (yawn!) - please bring on a stable version quickly - I'm using Opera which is not bad at all and is a poke in the eye to the great mammoths. I may with stay with the Winfrey and dump Fireflop.

So much for 3.5.1 or 3.5.2 fixing the critical bugs. I'm finding Firefox 3.5.x almost unusable with all the constant lockups.

Same here. Used FF since the beginning w/ little to no problems. I'm starting to find that 3.5.x is unusable.

I used to really like this browser, but half the time it refuses to close That little 'load dial' just keeps on a-spinning. I'd rather switch than fight.

I still use ff3.0, however, ff3.5 has caused me nothing but trouble. i work as a web developer on a legacy app. everything, over time, has been patched and massaged to work cross-browser. ff3.5 comes in to play, and all of a sudden 1/4 of our customers experience insufficient browser behavior. what happened to legacy support? at least IE8 gave us the "compatibility view" button, which turned it into IE7. At least our customers had a solution while we worked out the changes. stupid.

Crashes constantly! since install a few days ago..0x0000007E error out the wazoo!
