Firefox Community Forum

This will be a long question and in 2 parts, so I'll apologize up front.

1. I am running FireFox on my 11-year old MacBook and love it (MacOS Mojave version 10.14.6). However, my printer just crapped out, and my new HP 9120e requires MacOS Big Sur (11.x.x) or later. If I update to that OS, will I still be able to use FireFox? If so, where do I find it (see Question 2, below)?

2. Since my old MacBook is clearly reaching the end of it's life and my Excel and Word apps are also ancient, I am trying to transfer all my stuff onto a "New" MacBook that is running MacOS Monterey version 12.0.1. However, the "New" computer (I will not say "improved") has been a reliability nightmare and I just had it in for service. They wiped my disk clean to install the Monterey OS. So, other than Safari, I have no browser (or anything else for that matter). When I go to the App Store to download FireFox, and don't see it anywhere. Help!

Hello all, I just installed Firefox 138.03 64 bit with no problem and it seems to be working great as usual however I did notice an error in my Event Viewer which is Event 7023 Service Control Manager which was about The Mozilla Maintenance Service terminated (please see below). I have never seen this error concerning Firefox and I have been using it as my default for years now. I have no idea what to do to correct/fix this or if I should be concerned about it. I went to Services and the Mozilla Maintenance Service is set to Manual but when I tried to start the service it said it could not start the service because of incorrect function. Could someone please guide me as to what is going on and what I should do. Thank you in advance.

Respectfully, Don

Hi Forum! My Firefox is constantly (weekly) asking to update, even though we're on the latest version (right now we're on 138.0.1 (64-bit) I've reinstalled Firefox a couple times but the issue still persists. I'm not sure what my next steps would be.

Thank you all in advance, I appreciate your knowledge and time!

With the progressive rollout of tab groups having ended (I am assuming that because they are available by default in fresh installations), I would expect them to be available when I sync with my Firefox profile. However, when I sign in to the browser to sync all my settings, the option disappears. I am more interested in why the rollout never reached me than being told to enable tab groups in `about:options`. The profile switcher is also not showing up, but I am not sure if that is still in beta.

It seems like every week I've somehow muted the audio in a tab. I think this started a few months ago, but I can't remember seeing any sort of an "upgrade" alerting me to this new functionality. How do I get rid of it?? It's driving me nuts. I search google for a solution, and it's horrible AI search just refers me to an ancient thread that does not work.

Btw, I just saw an announcement by Mozilla about modernizing itself. How about getting rid of the crazy About:Config and making it easier for users to make changes?
