Solved Firefox suddenly locking @ startup

Sup guys?

I've been using FF without problems for years.

Yesterday, suddenly, whenever I execute Firefox, it locks for about 10-15 seconds.

(get a "not responding" prompt in file manager)

It all started yesterday when Firefox 22 was installed, (well, AROUND that time) and now it locks each time I start it.

It releases itself after about 15 seconds.

I've tried uninstalling it, reinstalling it, removing all plugins, and I'm just about going insane.

Any advice?

Thanks

It was lastpass indeed, evidently a problem with the binary.
