When I launch Firefox 3.5.2 on my machines I have upgraded to Snow Leopard (I've tried 3 different machines), it doesn't show up on the foreground. I have to click the window (or tab to it) to make it foreground. This worked fine on 10.5.8, but under 10.6.0 it doesn't come up on top. Even if there are no other windows up, it still doesn't receive focus. And if there is other windows open, it shows up behind them.

same here.
 
Has anyone else noticed when they just type in a word in the url box, it takes a long time for it to load the first time.

This was normal performance for me with Firefox 3.5.x (upgraded over Firefox 3.0.x) until I deleted everything related to it (using AppZapper) and re-installing, at which point performance returned.

I installed it fresh with a clean install of Snow Leopard and it's been fine.
 
I did a fresh install of SL and Firefox on both my iMac and Mac Mini both are running the latest version of Firefox and am having no crashes and no problems.

Mine starts up uber-slow. More than 20 bounces on a macbook air while Safari takes 2 dock icon bounces. I do have 6 add-ons though, haven't tried troubleshooting yet.
 
No crashes here at all. However MultiFirefox crashes like crazy. I have had to resort to creating a Symbolic link to firefox-bin.
 
I've had terrible crashing problems with Firefox on Leopard since version 2.5, through 3.0, and with 3.5, 3.5.2. My crashes usually occur within 5 seconds of startup. I can restart 5-10 times and it will finally stay up. Then I'll get crashes sometimes when I close tabs or windows.

Upgrading to Snow Leopard seems to have no effect on my crashing. Firefox crashes just the same for me on Leopard and Snow Leopard.

My crashes occur whether I'm running loaded up with extensions or with a brand-new profile with no extensions.

Someone earlier in the thread mentioned Firefox problems when running with Grown and/or Hazel. I have both... I turned off Growl, and lo and behold -- Firefox starts without a problem.

What the hell is up with that? Going to search for more info on this issue. Growl is pretty ubiquitous now, I guess I'll have to live without.
 
Mine crashes also on version 3.5.2. I tried a reinstall but it didn't work. I did however find that the 3.6 alpha1 doesn't crash for me. It's disappointing to lose all my add-ons, and also that I'm using ALPHA software, but it will be like Christmas every time an add-on gets updated to work. Silver lining, people. Silver lining. Also... how rebel am I? Living on the bleeding edge and all. I noticed 3.7 pre1 on their FTP too. I am FAAAAR too chicken to try that though. I'd rather just bleed than die a firey death! ;)
 
To all you people having no problems with SL and FF: What happens if you click on "Help" in the menu bar?

It crashes. We don't use the Help text, I guess. I've not had FF 3.5.2 crash using SL for any other reason. It definitely crashes when I click "help" though. I was able to click "Help" once, and it showed the help options (although they were ghosted/not selectable). Now any time I click Help it crashes...
 
No issues with Firefox on three different machines running SL. I did find that FireFTP plug-in wasn't working, but last night I noticed there was an update to it and it seems to be working just fine now.
 
When I boot into the 32-bit kernel, I haven't had a single crash in Firefox 3.5.2. I usually have a blank page set as the start page and Firefox loads almost instantly on my week old MBP. Then I hit the home button to load 7 tabs and they come up within 5-10 seconds or so. A few of them are pretty heavy pages as far as Flash content, etc.

My guess is that a plug-in or combination of them is causing issues for people. These are the ones I currently use and have had no problem with on SL:
Adblock Plus
Evernote
Download Statusbar
Google Gears
User Agent Switcher
Web Developer

Now the 64-bit kernel is another story. I booted into it just to try it out, and within 30 seconds of opening Firefox it crashed.
 
It crashes every time I click Help.

So there's something wrong somewhere... might be a problem with Firefox and it's more likely a side effect from Snow Leopard...

Goodie! :p
 
After both an upgrade and a clean install, Snow Leopard itself was crashing 10x/day for 2 days while i used Firefox with half a dozen extensions. I switched to Safari and NOT ONE crash of anything since!!!
 
I have the same problems with Firefox. Hangs when trying to start and usually hangs randomly, bumping up the CPU usage. I found this in the Firefox Knowledge Base:

If you update to Snow Leopard, and Firefox crashes when you start it, rebuild the font caches.
1. Start OS X in Safe Mode (hold Shift after you hear the startup chime).
2. Restart your computer normally.

Now with that being said, I tried it and it didn't work for me. Maybe it'll work for someone else.

Update: Ended up going the AppZapper route. Works perfect now. If only I can remember what add-ons I had now...
 
No crashes on me. First time I'm running Firefox as my main browser in OS X, because there's no working adblocker for 64-bit Safari yet.

Do you have many plug-ins?

You might as well just run Safari in 32-bit mode. I started doing that to get Adblock and MultiClutch to work again.
 
Hey, I've got FF 3.5.3 and the first time I launch FF, the damn window shows up behind everything else, and is not active (I have to click in it). Damn annoying. This does not occur on Leopard.
 
Firefox never crashed for me BUT it eats ram like crazy on SL :eek:

700 MB of Ram for a webbrowser ? Safari takes like 40 MB :confused::eek:

I think FF has problems on SL

No, it does not. With a bunch of extensions installed Firefox 3.5.3 uses ~150MB on my system. And that is after a week of the app running.
