Firefox コミュニティフォーラム

i have deleted Firefox and reinstalled it. after logging in with my account i don't seem to have any details with the browser. it is fresh like new. i have tried syncing it but it is still blank as possible

I am trying to sync FF to a new pc laptop from my old pc laptop. I am signed into FF on both devices, but they won't auto sync, even when the (orignal) says that it is. My old laptop is still running on Windows 10. Could this be the reason? If not, please advise how this can be accomplished.

Hey mozilla team,

I have issues with firefox sync as it doesn't sync old search history. Firefox Sync works perfectly for recent search history and chronic, but I imported an old profile (xyz.default) to firefox and logged in with my mozilla account. Started synching so that the old profile's history gets merged with the current one. It doesn't. I can see it in the imported old profile, but if I check history on another device, it's not there (aka only locally but not synced yet).

Is it generally possible to add an existing profile and then syncing it to merge it with the current search history one?

Three times now this year, I have been automatically signed out of my Firefox account on desktop with no cause. No updates or data clearing to cause it. Every time when I log back in despite having my Firefox synced to my mobile app, my bookmarks & passwords all break. Passwords deleted, bookmarks dysfunctional. I try syncing to restore them. Doesn't work. If I restore from backup, it fixes my bookmarks, but not my passwords.

After the second event like this, I changed my Mozilla password, but seeing as this just occurred a third time this year, that didn't stop it. I reiterate: I DID NOT SIGN MYSELF OUT. I DIDN'T DO DEVICE MAINTENANCE THAT WOULD HAVE SIGNED ME OUT. Sync SHOULD restore these but isn't.

My personal laptop was being repaired, and I was using my mom's old laptop until mine was fixed. I logged out of her Mozilla account on that laptop and signed into my own. Now that I have my personal laptop back, all of my passwords, bookmarks, and extensions are mixed in with all of hers. I don't know what to do, and I'm worried that if I remove bookmarks from my account, it'll create a domino effect that results in a catastrophic Mother's Day.... Please help, I'm not good with technology, I'm just a geology major.

I have a Firefox account. I am logged into my Firefox account on both my desktop and mobile phone. I want to sync them. I cannot do it. I press the three horizontal bars and it does not work.

I have been trying to clear out my bookmarks fro several days now and every single time they are restored. I have tried unsyncing my phone and computer and saving backups to try to force restore it to the cleaned up version but it always restores every single bookmark even to the original folder after I moved them around.

I used to be synced across two laptops and my iphone but no longer. I am signed in to my Firefox account on my Windows 10 laptop and on my iphone. The windows 10 laptop indicates that I am also signed in on my Windows 11 laptop, but when I run Firefox on my Windows 11 laptop, it indicates that I am signed out. When I attempt to sign in (on the Windows 11 machine), I get an "unexpected error" flag and I cannot sign in.

How can I fix this?

After the most recent update, my desktop version of Firefox keeps disconnection Sync so my passwords disappear. I also have an iPhone Firefox app doing Sync. The passwords reappear when I reconnect Sync on the workstation, but I want the desktop workstation to be the master and the passwords to always be available. How do fix it?

When I'm trying to login to Sync my Firefox account, I'm getting a cors error after putting in my email address and clicking the sign in button. This is on a new profile with no extensions installed on 150.0

Im trying to sync my android to existing account on PC. Phone says my firefox login incorrect yet when I go to firefox settings , it shows my name and password that I used to try to log in with phone. I then tried the scan option, but when I phone up to pc screen to QR code, it just sits there. SO I think ill just change my password. I go to password change section and it sends me the code via email. I input the code and brings me to change password screen yet when i try to change it, it states the prepopulated old password is incorrect. I am logged into PC with this info so how is it incorrect?

I have two computers that I use and I have them setup the same. Both have Windows 11, both are the same model, HP. One computer has 260 passwords and the other has 253 passwords. Why aren't they the same. Same sign in name Ronald Cogan, same email, same password. But when I bring up the one computer it shows 260 passwords and when I move over to the other computer it show 260

I've exported my bookmarks as an HTML file on my old computer (Win 11 Firefox ver 149.0.2) using a USB drive and tried to upload the file to my new computer (Win 11 Firefox Ver 149.0.2.). Only a few dozen of hundreds of bookmarks transferred. Repeated tries simply add the same bookmarks to the menu.

I've tried sync. Both computers are signed in and are correctly listed in the connected services box. Syncing is ON and when I select the Sync Now button on either computer screen, the Sync Now switches very briefly to Syncing and then back to Sync Now. Sync has transferred no data from my old computer to my new computer.

Any ideas are welcomed. Thanks, Jagwriter
