Firefox Community Forum

I have set up a new Windows 11 PC (brand new installation). I installed Firefox and tried to sync, because I want to copy settings, history etc. from my Windows 10 PC.

However, it fails. I enter my password, then it asks me to enter a code sent to my email. I enter that code, and it says "Bad request" and "Something went wrong. Please close this tab and try again."

It's not the most helpful error message. All I can do is retry, but after 20+ attempts, I think there is something wrong with the 2FA.

I'm able to successfully log in to https://accounts.firefox.com/ on the browser without any issue. That uses a 2FA code from the authenticator app on my phone.

Any ideas? Is there a better way of copying my browser to the new computer? I was thinking of just copying the Firefox profile folder, but I don't want to end up with it duplicated since my Windows 10 PC is still active.

My hard drive crashed and I have recovered the files. I have found the latest recovered profile but can't integrate the bookmarks and passwords into my current FF. I've read the how to articles but can't switch profiles. Help thanks.

Help, My computer performed an automatic update, rebooting itself and all the history on Firefox has been lost all my open tabs have disappear. I followed other instructions to open the Profile Folder, but the only 2 files there are the ones created after the reboot. There are no previous files. Thanks, Juan

I've been using Firefox for 15 years and since syncing has been available, all my tabs and favorites have been saved. Yesterday I saved new windows 10 and when I log in to mozzila, there's nothing?

I had four windows open with a few tabs in each. After a hard reset of my computer, Firefox doesn't recall any of those windows so I have no way to restore them. This is keeping me from accessing two different Outlook accounts. Any suggestions are helpful. I do not have a "restore previous session" option anywhere. Running 133.0.3 on Max OSX 14.7.1.

I follow the instructions on how to Sync and save data on my mobile, but there is no option in the options as described. I am logged in on both the phone and desktop.

Moved to different pc, logged into my account, all bookmarks gone. What is going on? The sync even synced with empty bookmarks, and I guess everything I bookmarked is gone now.

I updated my Firefox browser to the latest version (133.0.3) and lost all of my bookmarks (there were so many). This has never happened to me with previous Firefox updates. How do I get these bookmarks back? I am devastated right now and really want my bookmarks back. Please help.

UPDATE: I read several previous questions and support about recovering lost bookmarks prior to posting my question. None of them applied or worked in my situation. This latest update version 133.0.3 overwrote everything in my local Mozilla folder and my old profile did not seem to exist anywhere, but after much searching I did eventually finally find the last bookmark file (after selecting to view hidden files, searched for places.sqlite in my C drive) on my computer from before the update. Next step is to import them.

I use to be able to integrate my excel calendar and my wife's. Entries were different colors and changes on my computer showed up on my Ipad. Now I have my calendar but I can't find hers. Does she need to make a change on her excel as well?

I inadvertently installed a new version of Firefox/Mozilla and all the previous bookmarks I had saved now appear to be gone. I don't want to try to recreate my list of bookmarks again, is there a way to get them back? I tried doing an import of bookmarks but it's only showing a few of them and not nearly as many as I had before. anything you can suggest would be very helpful!
