I seldom use Chrome (except here at work), but at home, facebook will not work well on Firefox any more, and so I have to use Chrome. However, when using Chrome at work, it changes my default search engine to "MyWay" or something like that, and I have to type google in the address bar, even though that is my home page. At home I have Windows 10, and at work I am using the ancient Windows XP! Some people at work have upgraded to Windows 7, but my computer here is too old for that upgrade. Since I'm part time, I guess they decided that I did not need it, but I do need a newer computer to run a newer version of AutoCAD. I installed AutoCAD12, but it is very slow, and so I generally go back to AutoCAD5 but cannot open files that others have saved in AC12. I keep my history in Chrome fairly clear all the time at work. I should probably clear my history in Firefox at home. This would have been a good topic to cross-post on the computer forum.

RitaWeeda, You can set Firefox not to automatically install updates. Current versions ... Options \ General, scroll down to Firefox Updates section and select "Check for updates but let you choose to install them" It may be under a different menu structure if you're on an older version. It may still advise that an update is available but won't automatically install it. You can check manually check for updates by clicking on Help / About Firefox. It will check from there if any updates are available, advise you accordingly, and offer to fetch and install. I've been using Firefox since the 0.xx versions.

If you don't mind getting a little techie, you might locate your active Firefox profile (go though Help -> Troubleshooting Information), exit Firefox (important to exit), move the profile folder some place safe such as your "Desktop" and re-enter Firefox. It will create a new profile folder that will probably solve your problem. You will lose extensions, bookmarks and their keywords (I've did that before too). Like a fresh start. But since you saved a copy of your profile, you can always retrieve bookmarks, etc. Profiles - Where Firefox stores your bookmarks, passwords and other user data I know that's not for everyone but it's really pretty easy. Worse come to worse you can always re-enter the newly created profile folder, quit Firefox (again, important to exit or some of your changes may be overwritten), select and delete all the files/folders and COPY all the files/folders from your saved profile in there and you'll be right back where you started. Like I said, it's not something everyone would want to do but... that's probably what I'd do. :) In fact, I'm on my bedroom computer right now. I have a little one line script that copies my places.sqlite bookmarks file from my living room computer to this computer. That way I have the same bookmarks in here as in there. I haven't tried Firefox sync in ages. It might be fine now but if I remember correctly, it sorta jumbled bookmarks, putting duplicates in subfolders, something like that. I don't exactly remember. But probably for that reason, I just started syncing relevant files and it's worked fine for me. I don't sync to my phone though. I suppose that's where Firefox sync might come in handy? ETA: When you go "into" your active profile through Help->Troubleshooting, you'll be inside the folder you want to move. You'll want to go up a level to do the actual move. I'm sure you'd notice that but someone else might not.
