I have got my issue solved. It had nothing to do with Firefox or Ubuntu updates or anything like that. Neither was it google search bar. It was the add-on that I had for the browser. "Show IP", was the one bugging the browser.
Strangely I have been using this add-on for some time now and it worked perfectly. This is the first time I came across such weird behaviour of this Add-on. -- Firefox freezes often https://bugs.launchpad.net/bugs/226878 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
