Originally, I was annoyed that Firefox was saving tabs when I closed. So I tried clicking clear history on close. Now it won't open at all. I tried re-installing but still when I try to open it, it doesn't load anything and eventually says not responding.

Chosen solution

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.

Start Firefox in Safe Mode {web link}

Type about:preferences in the address bar and press Enter.

Select Privacy.

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.
