When im browsing, Firefox 4 randomly hangs for ~10 seconds saying its "Not Responding", then it returns to normal.

I dont seem to see a pattern on when it hangs, sometimes its when i open new pages, sometimes im just scrolling, sometimes i'm not doing anything...

It didnt seem to happen before i updated to FFx 4

My best guess is it happens when its trying to "Sync"?


It's not that bad, but it gets annoying after a while.

It is also possible that Firefox is doing maintenance to places.sqlite (bookmarks and history). If you keep a large history or have a lot of bookmarks then you can check that out as well. Also make sure that security (anti-virus) software isn't blocking access to files in the Firefox Profile Folder.

Create a new profile as a test to check if your current profile is causing the problems.
See:

There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins"

If that new profile works then you can transfer some files from the old profile to that new profile (be careful not to copy corrupted files)
