Firefox 社群討論區

I am using the same account (my school email), and everything else sync successfully.

Tab groups saved on my Windows PC didn't show up on my Macbook; tab groups saved on my Macbook didn't show up on my Win PC. Is this a feature or bug?

I recently got a new PC, and all my information was erased from it. I thought it wouldn't be a problem, as I expected to get everything back by logging into my account. However, after trying to sync my account for hours and searching on Google and YouTube for solutions, none of my information has returned.

When I contacted the person I bought the PC from, he said he couldn't help because I had forgotten to do something, possibly related to a Firefox update. I'm devastated and was hoping someone here could help. Is there a moderator or administrator who could assist with account recovery?

"This profile was previously synced to a different account To keep your data organized and secure, each Firefox profile can only be synced to one account. To sign in using xxx@xxxx.xxx, create a new profile."

So I deleted my old mozilla account since I abandoned the email that it was linked to, but when I tried to sync with my new account I get this. Is there anyway to do this without having to make a new profile?

I tried making a new profile and copy and pasting my profile into the new one, but still get the same pop up. I guess there's something in my profile that says it's been synced before, is there anyway I can find that and delete it or change it?

I had to re-installed from 0 my windows. I was sure my Firefox account had all my passwords and logins because I had problems in the past regarding this. Installed Firefox into my new fresh windows. Hit the Sync bottom. Lastly, remove the old Firefox account login from old windows (for safety).

Now I checked password, 0 passwords saved.....

I am trying to re-sync but nothing happens...

My bookmarks bar, etc have will not synced with my Firefox even though I ran "sync" several times. I haven't used this laptop in quite awhile, so I had to log in and sync. Also in my themes, a certain creator "MaDonna" has error messages on all of them" Cabin in the Mountains (and all others by her) by MaDonna could not be verified for use in Firefox and has been disabled." In my extensions page, I get the same error message. I am beyond frustrated, I'm also very computer literate, but this mess has me baffled and frustrated :(

I have a Windows Surface Pro 8 and when I set it up, I had no issues with the Syncing or Add ons/Themes/Extensions, everything synced just fine. I have Theme categories set up, and that's not even on the Themes page. I have logged into all of my Firefox/Mozilla accounts. Can anyone help?

I have 3 devices connected to Mozilla account, 2 smartphones and 1 PC and NONE of them are syncing properly, bookmarks sync perfectly and everything else fails miserably. Some part of history does sync but nowhere near the full history. Syncing of open tabs is *completely* broken.

Yesterday I only change the photo in my Firefox profile. Today I can't log-in to synchronize my account. When I click on "Anmelden" (German for "log-in") at the top right corner, a new tab opens, I can enter my e-mail adress, klick onto the button "Anmelden oder registrieren" (German for "log-in or register") it fades out and nothing else happens. I can access my account here as I logged in to send this message. What is the issue? How can I start synchronizing my account again? My Firefox version is 146.0 Thanks in advance, Chris

I have switched from chrome to firefox on my windows 11 laptop. I want to do the same on my pc but after signing into the Mozilla account, the bookmarks do not come in. History, and other things seem to work fine. I tried manually synchronizing in the settings over and over again but nothing works.

I have no idea what to do other than going back to chrome where things just worked and I didn't have to spend hours looking at forums for solutions that do not work...

here's a screenshot from the last txt file

In the settings of Firefox there is a search bar you click it to type things in to search settings but I cant search settings? I type "Favorite" and there's no settings for favorites bar behavior? No, I don't want the favorites bar to delete itself after I click on anything. I want my favorites bar to be a favorites bar and stay there and not go away anytime I click on anything. It shouldnt just be there only when I click a new tab.

1) Why does searching the settings for "favorite" not display any favorites bar settings? 2) Why are my Firefox browser settings not persistent between multiple computers when I have enabled "Sync"?

Everything is gone, I have had to reinstall windows 4 times in the last week with a new PC and now all my sync data is gone...Chrome remembers everything fine and Mozilla did remember everything until this install and now its not syncing anything.

If this stuff is gone so am I.

Have tried logging in with my google account, tried logging in with Moz account, tried sync button over and over tried restarting, tried uninstalling and reinstalling and manually deleting all the folders STILL NO SYNC DATA AT ALL.......

During the last desktop update I lost all of my bookmarks. I’ve tried to sync between my iPhone and desktop but when I finally got paired nothing happened with the sync from my phone to desktop

After reinstalling my computer system, I logged into my Firefox account again, but the data synchronization failed. All my previous data is gone, including bookmarks, passwords, and widgets. What happened? I can't find them in the mobile app either.

Hello, After performing a clean install of the OS, I logged in to my firefox account. But it is not syncing the passwords. I tried installing firefox to my phone, also not syninc. I think btw, it is syncing but my passwords are not there. Here is the log: https://pastebin.com/DH0wuERM Any help appreciated, because there were more than 200 passwords there. Thank you

I recently switched to Linux on both my laptop and desktop computers, and I have started having an issue where after closing Firefox, the process does not end fully, leading to a Firefox crash notice after a minute or two.

This seems to only happen when I have sync turned on. It always says "syncing..." and never finishes, and logging out of my account or turning sync off fixes this problem. However, I'd really like to be able to use sync across my two systems.

My laptop is running Pop OS, and my desktop is running CachyOS. Making a new account fixed this error for a few days, and now it is happening again.

Here is my newest crash report: https://crash-stats.mozilla.org/report/index/9adbdc82-3cfa-49b7-8bad-e6e590260319
