Firefox Community Forum

Hi there,

I've recently made the move to Windows 11, and since then I've been having loads of issues with firefox hanging and crashing. I've been able to correct the issue for about a week at a time by clearing my startup cache, but I did so incorrectly recently and it corrupted my profile, resulting in the need to create a new default one.

I'm able to launch firefox okay now, but when I try to sync my bookmarks and settings, firefox freezes every time immediately upon login. Is there a way I can sync my settings without using the firefox UI in order to circumvent the crashing issues present in the UI?

I recently upgraded from Windows 10 to Windows 11. I was under the impression that my bookmarks would be saved to my Mozilla account and I could then log in on the new computer and the bookmarks would come over also. Is this accurate or will I have to go about recovering my bookmarks a different way?

As of now when I log into Mozilla I get a message at the top saying "The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. I clicked Learn more and tried the troubleshooting options, but no luck in fixing the message or issue. Thanks for your help.

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 uninstalled Firefox on my computer and reinstalled it, but when I logged in, the account couldn’t sync, it was as if the sync couldn’t retrieve any data from the server. Nothing happened at all.

On my Android phone, the data is still there, but when I tap “Synchronize now,” nothing happens either. I’ve tried signing out and signing back in multiple times, but still nothing works.

I also tried switching to a different computer and a different internet connection, but it still didn’t work.

What should I do now?

Firefox was somehow reset after windows update restart. I was trying to sign in to sync, but sign in button gets blurred/disabled, and nothing happens then. I am afraid that I lost my previous session also.

I was trying troubleshooting mode too, but behavior is the same.

Otherwise I can login to my Firefox account web, and I am logged in on my smart phone still.

захожу в свой ак, но ни закладок ни паролей нет, год назад синк работал, все перенеслось, даже если и отключил синк, то должно же хотя бы годичной давности все перенестить

Firefox updated to the latest version and it lost everything. All my saved passwords are gone, all my bookmarks, data, etc. It said I could sign in with my account and it would sync them and bring them all over, it didn't. I can't use the original profile because it says it's outdated, I don't even know if it's the correct profile anyway. What am I supposed to do?

Hey, I am trying to synchronize my mobile tabs with my desktop app. Unfortunately, this is not working. I am using the latest version of Firefox and Windows 10. Any ideas how and if I can solve this problem? Thank you in advance.

I can no longer see a list of tabs from other devices. My computer was wiped recently and I was using the tab sync function to see the tabs I had open before the wipe. Now they have vanished. How do I get them back?

"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 moved to the Firefox flatpack after the Debian version couldn't display the code inspector/ web developer tools anymore (it was blank amid other likely javascript-based rendering errors). I only include this context in case some one else has the issue and searches for it.

I want to sync all my tabs from the Debian version to the flatpack version and similar to this solved issue I cannot access those tabs from the firefox view. However I am also unable to access these tabs from the sidebar. I am only able to access these tabs from the account menu but this would have me open each tab individually which is not feasible for me.

Is there a way to fix the "Check your internet connection If you’re using a firewall or proxy, check that Firefox has permission to access the web." error that comes up in both the Tabs from other devices sidebar and Firefox View menu?

I was logged in to my Firefox account and was syncing with other devices, so I thought I was all set .

I formatted my C drive and reinstalled windows, but logging back into a fresh install of Firefox, none of my extensions showed up. Bookmarks and History, yes. But no extensions.

I've lost them and now I don't even remember what they were. Is there a way to check the history in my account to determine the lost extensions?

Hello, I imported Bookmarks when I came to Firefox from a previous browser. The experience was terrible and challenges still linger. Firefox has come a long way, however UX still seems to be a 2nd class citizen. Bookmarks now has somewhat duplicate directories and this in turn is causing desktop/phone sync doubt and is likely missing bookmarks.

When sync breaks, it is so confusing. How can I simply have a working Bookmarks sync on desktop/phone?

Perhaps there was a challenge when I need Bookmarks to appear in the top bar when a new Tab is opened, as this was contrary to default Firefox settings.

I wanted to synch my current settings in my browser to import them on my new laptop. When I tried to login to my account, I the message from the attached screenshot appeared. So I created a new profile, got my stuff back to what it should be and then deleted the "new" profile. But now every time I try to get into the correct profile and login into my account, I still get the message from the screenshot. I never ever synched with another profile before and never had an issue in the past. Right now I am rather pissed off, because I lost atleast some of my bookmarks during this whole ordeal.

I reinstalled the operating system, so to speak, changed my device. I clicked the sync button and it worked. I reinstalled the operating system and reinstalled the browser. I logged in, nothing happened. I rebooted, nothing changed. I clicked sync, everything was the same. Where are my bookmarks and passwords?
