Since upgrading to Firefox 8.0.1, it is hanging when I try to open it. Deleting profiles etc. doesn't help. I suspect the problem has to do with caching or history, since when I first quit after upgrading I had to force-quit as it was hanging.
bold textMacOS 10.5.8 is my operating system.
There is no actual crash, thus no crash ID--it just hangs forever and eventually I force-quit.
Restarting the computer hasn't helped
Downgrading to previous versions didn't help.
Deleting profiles and preferences doesn't seem to make any difference.
Apparently clean re-installs hasn't helped.
If option-opening is really safe mode on a Mac, then that isn't helping, either. It's the same hanging.
No problems are being noted with any other software.
I'm totally stumped--what else can I take off for a cleaner re-install?
Additional System Details
Unknown--I think they're deleted now anyway.

This sounds identical to the problem I've been having, except I'm running Win 7. dancer1

With a minimum of 8 users (who've bothered to post) experiencing an identical problem, perhaps Mozilla should look into this.
This sounds like the problem i am having also. im running win xp 64 bit and when i try to launch firefox ver 8.0.1 it opens the window afew a pause and you see that its connecting 2 blank tabs are open and it just hangs there it will not connect and you have to kill the app in task manager it says its not responding. i have un installed FF and all add ons and tried a fresh re install but it does the same thing. ive ran the latest version of avast anti virus and detected no problems. IE seems to work fine but i hate IE. this problem seems to have started last night i was prompted to update adobe flash plugin. since then FF has been DOA. i hope someone finds a fix for this.
Mozilla, I am waiting for a fix, I want my 7.0.1 version to work again, your version 8.0.1 is not good, you cannot expect to disable all of our stuff....are you kidding me!?! I'll stay in Safari, not to worry, uninstalled Chrome when they got stupid and never use IE because it's always been stupid....Safari must be the way to go!
The Mozilla servers experienced a major outage recently and so if you have tried to download Firefox, or have add-ons set to update automatically, or are using Sync, you may have been experiencing server time-outs.
Start Firefox in Troubleshoot Firefox issues using Safe Mode (hold down the SHIFT key when starting Firefox) to check if one of the extensions or if hardware acceleration is causing the problem and to make sure you are using the default theme:
Firefox (Tools) -> Add-ons -> Appearance
Don't make any changes on the Safe mode start window.

Also make sure to update your plug-ins (Java, Flash, etc.)
The following help articles address crashes in Firefox:

If you have to re-install, do a clean installation:
- download Firefox and save installation file,
- uninstall Firefox,
- delete the Firefox program files folder, (important)
- re-install with administrator privileges. (important)
Firefox hangs the same way in safe mode.
There is no such thing as a Firefox program folder on a Mac, nor is there an "uninstall" to do, so these directions are not relevant to a Mac user.
The problem remains.
On Mac OS X, a crash can be caused by a preference file being damaged. Quit Firefox, then go to your user Library -> Preferences, find the file "org.mozilla.firefox.plist" and move it temporarily to another place, like your desktop. Restart Firefox and a new .plist file will generate. If that works, you can delete the .plist file you moved. See:
That was one of the first things I tried. That's not it--still hanging on launch.

It's very strange. When FF hangs I click on the yellow dot to minimize the FF window into the dock. After clicking it on the dock and restoring it FF works again.
Check to see that disk permissions are intact on all plug-ins in both the system-wide /Library/Internet Plug-Ins/ and ~/Library/Internet Plug-Ins/ folders. Move system-wide plugins into the Disabled Plug-Ins folder, and clear the personal ones.
Then delete org.mozilla.firefox.plist again, back up and delete the Application Support/Profile(s), and delete the Firefox folder in ~/Library/Caches.
Then run the Disk permissions fix, and restart and do a clean install.
Please post back your result.
What are the permissions supposed to be?
It's not possible to click on minimize while it is hanging.
If you run disk repair from the installation dvd, the report will show you where permissions differ and what they should be.
An example of some permissions reporting that Apple tells you you can ignore, is at:
however, since you are having issues that are likely related to the Firefox install and plug-ins, and probably aliases, it would be best to correct permissions issues to rule that out as a part of the problem. Also get rid of any aliases related to Firefox or its plug-ins.
I have been traveling and don't have the install CD with me to restore permissions.
I downloaded Firefox 9.0.1 and now the hanging is on the "Checking Plugins for Compatibility" dialog box.
Does this provide a clue to anyone?
I have been using version 3 for years, as every time I tried an update, it would hang. Same with 9. So I always had to go back and reinstall 3, where everything would be fine. 9 works on my laptop with Vista, and the new feature I wanted was the sync, to be able to sync bookmarks. Love that idea. But on my desktop with XP, could not for the life of me get Firefox to work with any version past 3.
Here's the solution that worked for me:
opened the version that worked, and saved bookmarks to USB drive. That's the main thing I wanted in the new version. uninstalled FF manually deleted all files in FF and Mozilla folders on the hard drive, including any folder named "mozilla" or "firefox" edited the registry (read about how to do this properly elsewhere) and manually did a search for and removed every single instance of "mozilla" and "firefox" that existed on the computer. Made sure I did search from the top of the registry tree rebooted installed firefox 9 imported bookmarks from USB drive
all works fine now! Years of upgrades not working, and a registry clean did the job.
