Always crashing. Now unable to open it. Tried all the suggestions.

Question

Firefox has been crashing all last year. A fresh reload of windows7 and firefox has not solved the problem. Different anti-virus programs have found no malware. Different "Pup virus" detectors have found nothing. I have tried every suggestion in troubleshooting, but still crashing. Now I cannot open firefox. I think that a clever infection has stalled the browser permanently. Will have to change to another browser, for reliability.

Answer 1

Sorry you are having problems, but hopefully they may be solvable.
If it is malware you have not yet successfully found and removed two things to bear in mind are that
# Some malware affects multiple browsers.
#Malware may continue to damage your computer, data or security.
So just switching browsers may not be much of a solution. My suggestions are as follows
#Try a clean reinstall of Firefox. That involves removing its program files (NOT the profile files).
# Then run scans again with multiple and fully up to date tools.
# If you then get crashes please report what the crash IDs are.
#Please explain how you get on by posting back to detail what you have tried and what the results were.
===Clean Reinstall===
Certain Firefox problems can be solved by performing a ''Clean reinstall''. This means you remove Firefox program files and then reinstall Firefox. Please follow these steps:
'''Note:''' You might want to print these steps or view them in another browser.
#Download the latest Desktop version of Firefox from [https://www.mozilla.org mozilla.org] (or choose the download for your operating system and language from [https://www.mozilla.org/firefox/all/ this page]) and save the setup file to your computer.
#After the download finishes, close all Firefox windows (or open the Firefox menu [[Image:New Fx Menu]] and click the close button [[Image:Close 29]]).
#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
#*'''Mac:''' Delete Firefox from the Applications folder.
#*'''Linux:''' If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it - see [[Installing Firefox on Linux]]. If you downloaded and installed the binary package from the [http://www.mozilla.org/firefox#desktop Firefox download page], simply remove the folder ''firefox'' in your home directory.
#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.
More information about reinstalling Firefox can be found [[Troubleshoot and diagnose Firefox problems#w_5-reinstall-firefox|here]].
<b>WARNING:</b> Do not use a third party uninstaller as part of this process. Doing so could permanently delete your [[Profiles|Firefox profile]] data, including but not limited to, extensions, cache, cookies, bookmarks, personal settings and saved passwords. <u>These cannot be easily recovered unless they have been backed up to an external device!</u> See [[Back up and restore information in Firefox profiles]].
Thanks
