A few months back something I did or probably the upgrade to Firefox 3.0 caused my navigation buttons to stop working. Also when I open tabs only the last updated URL is displayed in the URL box and it doesn’t change according to the current tab. Also saving bookmarks didn’t seem to work. Its quite a nagging issue when you cant stop, refresh or go back. With bookmarks not working I couldn’t keep track of a lot of online resources I was stumbling upon daily. I tried out various options to fix the issue. Nothing seemed to work. Finally today I stumbled upon the following steps which I tied out hopelessly to find out that it in fact worked. However as I couldn’t bookmark the site I cant guide you there. However these are the instructions that I followed.
Close all firefox windows (kill all ffox processes).
Rename mozilla hidden directory.
> mv ~/.mozilla ~/.mozilla.bak
Start firefox. (It’ll be starting with virgin state.)
After step 3 everything returned to normal. But as the following three steps were also there I followed through and found that it returned to my former state ie without navigation. So I redid steps 1 to 3 and left it at that. The remaining steps 4-6 are to restore your orginal settings however it didnt help me out. You can either try 1-3 and leave it at that or proceed through the remaining 4-6.
Delete genarated settings directory.
rm -r ~/.mozilla
Move back original settings dir.
> mv ~/.mozilla.bak ~/.mozilla
