Firefox 社群討論區

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.

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.

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!

My hard drive recently crashed but I was able to recover all the c drive files. I found the firefox profiles and have copied the entire folder onto my desktop in the new windows 11 computer. I can't seem to sync those bookmarks and passwords to the firefox. I think I need to change the default profile but can't get that to happen. I have copied the profile from the crashed computer to the profiles folder on the new one. Please help guide me through the process.

Thanks very much.

New computer, W11, completely updated. The old SATA SSD was removed from old PC, had W10 on it and that had FFx 133.0 installed; successfully transferred the bookmarks to another W10 PC but not the Passwords/logins. Transferred all the information from the Mozilla folder (per Firefox/Mozilla help) to a USB: plugged it into my new computer and did the same transfer of the Places, Key4, logins, and favacons to the new computer: no change. Just finished uninstalling FF and removing the Mozilla file from App Data, then doing a complete reinstall; then added the old places etc. to the new install. Nope, didn't work. So what's going on with FF and W11?? Is there a solution? I have been with Firefox now for over 10 years and have never had these kinds of problems moving my information.

MODERATOR: mark this question as solved, please. I truly don't know what happened or what I did other than what I have listed above, but late last night (12/10) I went to try moving all these things again ----- and they were in place, they had installed etc. I am at a loss as to why all my logins and bkmrks. are now on the new PC, but who am I to question fate, good luck or The Lord.
