Firefox Community Forum

I just accidentally deleted a day of history, now it has to relearn a bunch of stuff.

Please add support for undo, so that if you do it by accident, you can reverse it.

Firefox autofilling my freaking CC number though those settings are disabled. I want to know what Firefox file my CC number is stored in.

Give me the filename -- I'll do the rest...

I turned on Firefox this morning and its all changed I have no bookmarks no menu and no search bar I hate this new system Why cant i go back to the previous version ???

Starting the month of February 2026, I cannot get into the following websites anymore to do my on-line shopping. Walmart.com and King Sooper grocery store (Kroeger). I get messages to try again later all the time. If I use another browser such as Edge or Chrome, I can get in no problem. Not sure what is going on??? I chatted with Customer Service Reps at both sites, they don't know why I cannot get in with Firefox, unless some of your security certificates have expired. Help!! - Stan

I have moved my profile to a different location on the hard drive to make backups easier. How do I tell firefox where the profile is now located. c:\users\med\my data\PROFILES\mozillA\*.deFAUlt

If it ain't broke, don't fi(o)x it. Never try to be too clever. I cannot log out of OUTLOOK.COM, then after goodness knows hot long, it says that I have been kicked out and need to login again. CRAP!!!!!!!

I get the message: We're Sorry Firfox had a problem and crashed. We'll try to restore your tabs and windows. To help us diagnose and fix this problem, you can send us a crash report. I sent the crash report multiple times.

I added a screenshot of my MacBook Air info.

What seems like ages ago Firefox stopped displaying bookmarks I addition it would not add new bookmarks nor restore the existing ones. I've gone through all of the corrective procedures listed on and off but nothing works. As a final attempt I deleted the program and reinstalled it. No change. It seems to me that perhaps a missing file from another program or system is missing. Maybe!

I have been using an alternate system for some time. When installed it had no problem finding all of the Firefox bookmarks and placed them on the menu bar as "Firefox Bookmarks". I have no issues with using them but all new ones are stored in the current browser. Thus the new ones do not go into the folders previously set up. I've avoided moving them manually to the new system due to the volume but I am ready to bite the bullet.

I prefer Firefox but it's just not working.

Can anyone save Firefox for me.

I have a macbook air laptop (late 2010) and have been using the latest version of Firefox browser for browsing. It's one of the few browsers still available. Google is popping up with the message that my browser is no longer supported. Do you have any suggestions about a browser that may work (other than a new computer please)? Will Firefox be coming up with a new extended version that will work? Thanks!
