I've tried everything--Firefox simply won't open. I opened the troubleshoot articles, but none of the fixes did the trick?

Question

Firefox will not open. I tried every single troubleshoot recommendation, and it still won't work. I thought it may be under the "corrupt profile data" troubleshoot article, but when I followed the recommendations to change to a new profile, the profile manager would not open or run on my computer--as if it never existed. I tried downloading a different browser, and as soon as I imported my firefox data, it started misbehaving in the exact same way.
This is getting extremely frustrating. Anybody know what to do?

Answer 1

I am not sure it is a good idea to have two security programs, but presumably it will be ok if set correctly, but I certainly would not for instance run two Anti Virus programs they would be likely to conflict.
I am not sure if the error report may indicate Firefox is crashing but it needs the same steps anyway. So a brief explanation and a couple of suggestions.
<u>Profiles</u><br/>
Before even considering deleting or creating profiles a very simple & quick test is always worthwhile, using Firefox's Safe Mode
*[[Troubleshoot Firefox issues using Safe Mode]]
* [[Profiles - Where Firefox stores your bookmarks, passwords and other user data]]
Problems with the profile may prevent Firefox starting or cause all sorts of problems. <br />
(This is JUST FOR INFORMATION, I am not asking you to do anything.) <br/> Briefly the profile stores settings etc. and there are better options than just removing it. The simplest option is the Firefox Reset feature and although that looses extensions and some information it does at least retain bookmarks and passwords.
*[[Reset Firefox – easily fix most problems]]
More advanced users have better options available if they wish such as creating new clean profiles although it does need some care to be taken
* [[Use the Profile Manager to create and remove Firefox profiles]]
<u>Program Files</u><br />
The profile and the main program files are completely separate. Possibly your problem is due to faulty program files or their installation. A clean install involves deleting these files rather than the profile files.
<u>Next Steps</u>
# Try starting Firefox in Safe Mode following the instructions from the article linked above. It probably will not help but is worth a try.
# '''Do a clean reinstall'''
## you may want to copy or print the instructions
##download a new copy of the Firefox installer from <br /> http://www.mozilla.org/en-US/firefox/all/
##After the download finishes, close all Firefox windows (click Exit from the Firefox or File menu).
##Delete the Firefox installation folder, which is located in one of these locations, by default: (Windows)
##*C:\Program Files\Mozilla Firefox
##*C:\Program Files (x86)\Mozilla Firefox
##Now, go ahead and reinstall Firefox:
##Double-click the downloaded installation file and go through the steps of the installation wizard.
##Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.
