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 signed into my firefox account on my wife's computer and now ALL of her bookmarks, passwords are mixed in with my data. I've signed out of both accounts on that computer. I've signed out and relogged in on my computer. This is not a temporary issue. All of her data is somehow in my account. This seems like a MAJOR security flaw of the software. Were both using Windows 11 computers.

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?

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 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?

"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 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?

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.
