Firefox is not ending tasks in Windows.

What is happening is that Firefox is remaining as a background process in Windows 8.1 Update 1. Every time I start Firefox, there is no navigation, and requires a reboot of the system to fix. There has to be a better way around this. I also have screenshot pictures, but can't upload them here.

Chosen solution

Some added toolbar and anti-virus add-ons are known to cause Firefox issues. Disable All of them.


From what I have been reading from other posts on this forum, the issue may be caused by the clear history settings. It was suppose to have been fixed in v30.

Type about:preferences#privacy <Enter> in the address bar.

The button next to History, select Use Custom Settings.

At the bottom of the page, turn on Clear History When Firefox Closes. At the far right, press the Settings button. Turn on ONLY Cache and Form And Search History leaving the others off.

This is not a cure but will make it easier if Firefox locks up in Windows. https://support.mozilla.org/questions/997866 {web link}

Thanks FredMCD,

What I ended up doing is reinstalling Firefox. It looks like it didn't take the 33.1 update too well.

Glad to hear.
