Yesterday I could use FF (126.96.36.199) perfect, all the engines I had added were working and AFAIK, my bookmarks were also there. Today I brought back my laptop from hibernation, and upon starting FF, I noticed that the search engine icon had change. I clicked on the icon, and all the engines were gone! Instead of the icon being the default "G" for Google, all I have no is a little magnifying glass. On top of that, almost all my bookmarks are gone. The toolbar bookmarks are there, and any bookmarks that were stored in a folder as well, but any others that were just placed there without a folder are completely missing. I opened FF in Safe Mode and the engines came back, but the bookmarks were still gone . I have no idea what to do, I tried reinstalling on top of my current FF installation but it didn't help. Any ideas? Thanks, Apu EDIT: Forgot to mention that whenever I open FF, it opens in a non-maximized window instead of the usual maximized one too EDIT #2: I uninstalled and reinstalled FF, backing up my profile beforehand. I uninstalled from the Control Panel and also erased the folder from the Local Settings folder, and it still doesn't work. What's worse, for some reason my bookmarks toolbar is still there, which it shouldn't because I deleted my profile's folder. I'm even more confused now. EDIT #3: I managed to completely uninstall FF, and now the engines are back. I copied back my profile settings that I had backed up, and the problem came back. I'm suspecting it may be one of the extensions I have, but it's weird that one of them started giving me problems now.
