Why does firefox keep crashing? I ran a scan and there was no spyware or malware. I uninstalled and reinstalled firefox. It doesn't happen in safe mode.

Posted

For some unknown reason firefox keeps crashing on my laptop computer. I mostly just use the internet for surfing and for emailing. It is very frustrating when I am trying to write an email and firefox crashes. I have unistalled and reinstalled firefox. I ran a McAfee scan on the computer and it has no problems with spyware or malware. It doesn't crash in safemode either. I am in safe mode now otherwise it would have crashed multiple times while getting to this page and typing this message.

If Firefox crashes frequently but stops crashing when you are in Safe Mode that is a pretty sure sign that there is something wrong with your individual setup of Firefox on your Windows 7 machine.

(The 99 others claiming to have the same problem this week probably have their own distinct and separate problems - if you are one of those 99 it may make sense to start your own questions about your problems, if you do not see suitable answers).

Many malware problems would continue even in Firefox's Troubleshoot Firefox issues using Safe Mode, so the good news is that malware may not be your problem.

Note that safe mode does not disable plugins, you may wish to consider testing with your plugins disabled, just in case they are interacting with something. To temporarily disable plugins use

  • Firefox button -> Add-ons -> |Plugins|

You do not list the Firefox extensions that are in use, maybe one of them is a problem. I suggest you try Firefox with half of them disabled, if that solves the problem, the troublesome add-on may be in the other half, disable them all and then try with half of the other half enabled. (If you have more than a handful of add-ons it is faster testing like that than enabling or disabling one at a time)

One very important question is how do you know Firefox is crashing ?
will you please explain exactly what happens, and what if any error messages you are seeing. (If firefox freezes/hangs that may be different from Firefox or the OS crashing, and require different solutions).

On a general note the following articles may help with troubleshooting:

and if the problem is a true crash

It has been pointed out that one of the top causes of crashes currently relates to Comcast's Constant Guard due to use of Idvault. Something that the Company concerned is aware of and working on.
