My morning routine begins with a cup of good coffee, booting the PC and running the email client Thunderbird and the web browser Firefox. Firefox behaved strangely this morning, it simply would not load properly but hang in the interface. The tabs of the websites that were open in the last session were showing up but they were not loading at all. Killing the Firefox process and restarting the PC did not help.
Since this is not the first time Firefox acted up I started to troubleshoot the issue by disabling all add-ons to see if an add-on was the culprit. Firefox ran fine with no add-ons running in the background. I then enabled one add-on at a time to see which one was causing the hangs.
I found out that the password manager add-on Last Pass was the problem. I then remembered that I had the same problem about a month ago (see Fix Firefox With Last Pass Not Responding), and checked the Last Pass forums for news on the topic.
Some users were reporting problems with Last Pass, most of them were running a 64-bit edition of Windows 7, just like I do.
The solution was simple. Download the non binary version of the Last Pass add-on, and drag and drop it into the Firefox interface to install it. You need to disable the Last Pass add-on first so that the web browser starts up normally.
I’m not sure what the problem is exactly but the Last Pass guys should consider fixing it, as it is an annoying experience to witness the freezes every time the add-on updates automatically in Firefox.

I know this problem, as I’m a add-on victim too. With ~40 add-ons it is not easy to detect the faulting one. Last Pass is not on my list, so I’m not affected with this one. Until now I use the built in pw-manager with a own password.
I too suffer with this exact same problem. I’ve actually had some success with changing the Compatibility Mode on the firefox.exe to XP SP3. Who knows what all else that affects, but it definitely lessens the number of freezes I get. Notice I said “lessens”, as I still get an occasional freeze, but it’s nothing like the several-times-a-day freezes I previously experienced.
I use the software KeePass and it has a toolbar for Firefox. I’ve not had any problems with it.
I had to uninstall Firefox and all add ons and reinstall everything again. Problem is fixed, but what a timewaste.
Why did not you run Firefox in Safe Mode?
I had other problems with Firefox. I have 84 extensions and 30 something scripts, so something was always broken. Surprisingly I have much fewer crashes after complete reinstall. On other hand, couple of new annoying bugs seem to be introduces with AdblockPlus and Stylish conflicting.
I cant login to my fb. It only redirects me back to the login page after i have already tried logging in. I check my fb via my mobile phone. I’ve never had this problem before. Now, for the last week, i’ve had login troubles. FB IS THE ONLY WAY I CAN COMMUNICATE WITH RELATIVES OUT OF TOWN!?! HELP! HELP! HELP!!! Please fix it! I love fb & would hate to delete my acct! Please fix this annoying problem!!
Hey I began having problems with Firefox recently around the time I got Last Pass, so I was lucky enough to figure out what was causing Firefox to hang. One Google search brought me here, and I haven’t had any problems since.
Thank you very much!
