Firefox Community Forum

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

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?
