Firefox has become almost unusable-- slow to load- hangs- not responding-etc.
For the last several days, Firefox has become nearly unusable. It started using an excessive number of processes. Then I started getting very frequent hanging and "Mozilla Firefox (not responding). It may freeze for several minutes, and often I have to shut down and restart my PC. It then takes much longer than usual to shut down, and after restarting, it takes several tries to get Firefox to open. A couple days ago, I updated Firefox to the new version for Windows 7 Vista, and it may have actually gotten worse.
It took me about 25 minutes to type this short description of the problem because it froze several times.
