I had a Firefox debian version installed on my desktop running Ubuntu Ubuntu 24.04.3 LTS and now I just installed the latest 143.0.1 "Mozilla Firefox Flatpak" version.

How can I synchoronized or migrate all my data such as bookmarks, add-ons, open tabs, settings for syncing ?

Thanks in advance for prompt clear step by step answer.

Unable to pin extensions since i do not see the option to, clicking on the puzzle piece creates no drop down menu, when i go into the extensions menu the ... only allow me to remove or report, the manage extension shortcuts menu shows nothing.

Someone had me do an add-on. I have no idea what the add-on did. Nor do I know how to use the add-on or if it installed correctly. No one gave instruction on how to do what I am asking . So I am stuck with the need to make my scroll bar wider. I need detailed instructions for an idiot on the computer.

I have picked up some bug(s) on my Firefox that I cannot figure out how to get rid of. With a Firefox ID I have warnings of 3 Trojan Virus detected, Virus detected, hard drive infected, secure data notice and system alert. I also got a warning that my McAfee protection had expired which is very strange. Since switching over in 2010 from Windows to Linux I have never had protection of any kind and unlike Windows have never had a single problem. In addition when I was using Windows the protection that I had was never McAfee. I suspect that these warnings are not from Firefox given the misprints, spelling errors and the poor English. It is likely phishing from some third world country. How do I get rid of this obvious garbage permanently? Many thanks! Kris

I have arthrytis in my hand, and trying to keep that narrow moving in and out bar on the right of the page or drop down like the tab menu, is agonizing. WHY NOT MAKE IT WIDER????

I've usede Safari for years, but want to try Firefox. I've tried to import data, bookmarks and so from safari, but can't do it. Firefox says: Select the Safari file. But which one? And where do I find it? I've find the app Safari – but there's a lot of files underneath it.

The keyboard shortcut to take screenshots [Ctrl + Shift + S] used to work a few weeks ago but it has stopped working for quite a while now. Doesn't work on any site, I can only create screenshots by right clicking and pressing the button manually.

The article explaining why one should not downgrade ignores a critical reason why one needs to downgrade and that is when it turns out that the new version breaks an existing website!

I got bitten by this when Firefox "upgraded" me to V143 after which point the ticket system I use to support my customers stopped working. That same ticket system continues to work fine in Safari, Edge, Chrome and Brave, etc.

Worse, when one does try to downgrade, the old profile gets removed which means you lose EVERYTHING you had (tabs, bookmarks and presumably all the settings and saved passwords, etc). You need to be keeping the old profiles around so that they can be accessed again should someone NEED to downgrade. Fortunately I was able to use Time Machine to recover the old profile --- but somebody just didn't think this through.

Much as I have loved Firefox over the years, I'm starting to feel that it's time to give up on it and move to something else.

Turning off automatic updates is not a solution because eventually one will choose to upgrade manually and most people won't remember to make a copy of their existing profile. Should one then encounter a problem, you're back to square one

Very disappointing .

When switching to full-screen mode in Firefox while watching a video, the cursor won't disappear automatically until you move it. This issue affects all players except the native Firefox player. The bug appeared in version 143 and higher (affects all builds, including stable, Beta, and Nightly). I've tested the issue by rolling back the browser to versions 140 and 142.0.1, and everything works fine. There's a thread about this issue on the Bugzilla forum. macOS versions Tahoe 26.0 and Sequoia 15.7 are currently running. I can't test on other systems.

Hi Firefox community,

I’m not your usual tech influencer or a corporate “enthusiast”—I’m just a longtime open source user who’s spent more than a few years behind the veiled curtain, watching how this world of software and possibility unfolds. I love what Mozilla does for users like me. That’s exactly why I want to raise something: I keep seeing the word “chatbot” show up for Firefox’s new AI-powered assistants (like the sidebar and what’s coming next). But let’s be honest—“chatbot” belongs to the days of robotic customer service and scripted dead-ends.

What we have now in Firefox—powered by real LLMs (Large Language Models)—is a whole different species. Calling these assistants “chatbots” just doesn’t fit. It sells short what LLM-based assistants can do: they’re powerful, context-aware, and, at times, strikingly human in their conversation. New users might miss the true magic if we stick to old language. So why not call them “AI assistants,” “LLM-powered assistants,” or just “AI” instead? It would help everyone see the progress, and show how Mozilla’s still leading, not just catching up.

I’ll leave it open for discussion, but I hope others feel this shift too. Language shapes how we see these things—and sometimes it takes a Singular Fella (or maybe two) to nudge the world past old memes. Thanks for hearing me out, and here’s to a future where our assistants, and our words, keep getting smarter.

We are unable to stop playback from the controls in the PIP window for Apple TV when the video playback was started in the main browser window. If we press the control the playbacks stops for a fraction of a second and continues again. Other controls like mute etc. are working as exspected.

If we start the playback in the PIP window we are able to stop it!

If we use Youtube or Amazon as a video source the problem does not show.

If we use Troubleshoot Mode we get exactly the same behaviour.

Any Ideas?

The only Firefox will open a link in a new tab is if I force it to do so by right clicking each link and choosing open in new tab. Before it automatically opened in a new tab.
