Any suggestions appreciated. Running FF v4.0.1 on Vista64 - no real problems for some time now. Yesterday the icons in the bookmark dropdown menu disappeared - hundreds of them, none spared. All the bookmarks still work. Restarted FF in safe mode (no addons) but no change. Reinstalled the program but still no icons. Tried restoring from a previous .json file but that didn't work either. I doubt this is related to settings since none have changed lately. Any suggestions for something to try?
