After removing system fonts and reinstalling fonts, FireFox will not start
After removing system fonts and reinstalling fonts, FireFox will not start! When I start FireFox the "Mozilla Crash Reporter" opens as if FF just crashed??? I don't see any records in event viewer. I am using FF v3.6.3 on a Windows 7 box. I tried uninstalling 3.6.3 and installing 3.0.18 and had the same problem!

The files with submitted crash report ids are inside the ''submitted '' directory, from the directory you found the LastCrash.txt timestamp file.
The file names will begin with '''bp-'''
There might be more information from the crash report, but it might just tell us you are crashing the first time Firefox tries to use a font.
One thing I suppose you could do is select only those fonts you've got in Tools -> Options -> Content -> Fonts and Colors -> Advanced and then uncheck the '''Allow pages to use their own fonts''' option.
See http://support.mozilla.com/en-US/kb/Options+window+-+Content+panel#Fonts_Dialog
To be honest, I can't find anything on this Netscape Font Navigator and it sounds highly dubious.

Just installed Firefox 3.6. Firefox will not start and Firefox safemode does not start either. Using Task manager I do not see if started either. If I create a new profile and start from that window, Firefox starts up. I see no error windows/messages. I do have it listed in my Firewall as an exception program with Permit All. What is happening?

Firefox will not start, after reboot.
For a few months now Firefox will not start after I reboot my computer. In order to get it to start I click the exe then must go into task manager kill it, click the exe again, kill it again then, from there it will typically start, but sometimes it may take one or two more trys. When clicking the exe firefox will appear in the task manager under processes but will will start with ~7% CPU usage, then quickly drop to zero every time until it does actually open and start. I have ran a full system recovery and started anew after reinstalling mozilla several times failed to fix the problem. I run virus and spyware checks often and come up clean, and also run Chrome as a default browser.

You may be having a problem with some Firefox add-on that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?
Whenever you have a problem with Firefox, whatever it is, you should make sure it's not coming from one of your installed add-ons, be it an extension, a theme or a plugin. To do that easily and cleanly, run Firefox in [http://support.mozilla.com/en-US/kb/Safe+Mode safe mode] and select ''Disable all add-ons''. If the problem disappears, you know it's from an add-on. Disable them all in normal mode, and enable them one at a time until you find the source of the problem. See [http://support.mozilla.com/en-US/kb/Troubleshooting+extensions+and+themes this article] for information about troubleshooting extensions and theme. You can troubleshoot plugins the same way.
If you want support for one of your add-ons, you'll need to contact its author. -

Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; YPC 3.2.0; .NET CLR 1.1.4322; InfoPath.1)Do a clean reinstall and download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.

Firefox will not start in normal (hour glass for a second) or in safe mode (closes after choice box).
I tried all of the following with no success:
- uninstalling and reinstalling mozilla with no success.
- End all firefox.exe from the task manager and then open again the firefox from quick launch or desktop or program files folder.
- Change the firefox.exe name to firefox2.exe
- Start in safe mode and choose several alternatives after choice box, but nothing happen.
Please help.What is your computer system, and what Firefox are you using?
Start your '''Computer''' in safe mode. Then start Firefox. Try '''Safe''' web sites.

Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.
You can try these free programs to scan for malware, which work with your existing antivirus software:

After upgrading to 27, firefox will not start. Saw an error message during the upgrade process.
After upgrading to 27, firefox will not start. Saw an error message during the upgrade process but cannot remember.
Tried to run firefox.exe -P but receive error message:
XML Parsing error: undefined entity
Location: chrome://mozapps/content/profile/profileSelection.xul
Line number 18, Column 1:
<dialog
^
Running on Windows XP SP3. No problem whatsoever before upgrading to 27. Sending this from Chrome as I cannot open Firefox at all.Thanks jschaer2000: after starting it once in safe mode, I closed Mozilla and tried several restarts in normal mode. So far, all worked:-)
Thank you very much again.
Still the automatic update process bothers me: it took me several days to discover the reason to the malfunction, since when I removed the problematic version from Add and Remove Programs, I didn't pay attention at first that it was another version, not v26 which I installed from my folder.
In addition, I like to save the installation files before I run new programs and if I didn't have v26 exe file, I couldn't have operated Mozilla at all. Not that it was fun to remove and install again each time v27 didn't react, but it was better than nothing, I still prefer Mozilla over its competition. -

Firefox will not ''start'' and open a website from a Thunderbird email link. A link from Thunderbird will open once Firefox is ''already'' started, but will not initially start Firefox and proceed to open the Thunderbird email link.
I also have this problem. I cannot open links from a discussion board I frequent nor can I open links from my email. Also after opening my email, I cannot go to any other sites except my home page. I can then go no where else.
When I close Firefox and try to reopen it, it does nothing! I have to bring up the Task Manager and end the Firefox process before I can get back in.
To the best of my knowledge, this problem started with the new update to Ver. 3.6.9. I am running Windows XP Media Center 2005 -

Firefox will not start when computer is restarted.
When I shut down or restart my computer, Firefox will not start. I will click the shortcuts, but nothing happens. There is no error message and as far as I know from searching, I have no security applications prohibiting it from starting. Once I reinstall after my computer loads, it works perfectly. How can I fix this so I don't have to reinstall Firefox daily when I turn on my computer?
Hello ShirodieSchone, try to run Firefox once as Administrator (right-click: Run as Administrator).
also, if the above doesn't work, see if you can start firefox in [http://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode#os=win7&browser=fx19 safe mode] by by holding down the shift key while starting Firefox.
Otherwise try to boot the computer in Windows Safe mode with network support (press F8 on the boot screen) and see if that helps.
thank you -
