Firefox Community Forum

Hi, I'm running Sierra 10.12.6 on a mid-2011 iMac. I installed Firefox 115.33.0 in March '26, but now see a "not supported message" in the browser.

I downloaded the ESR version of this browser, but when I went to copy to the APPS folder it asks if I want to replace the NEWER one that's already there. ???

Now it says I'm running it on the ESR update channel. Did I just go backwards in browsers? When this ESR expires, if a new one isn't provided then, will I still be able to use/update/install Firefox on this IOS on this iMac?

Thanks! Elaine

You guys keep hijacking my browser and stopping all my work on a near weekly basis. Shutting down my ability to work on projects and stopping my browser from functioning in the middle of use. I can't even pay bills without you guys interrupting my browser with your bullcrap.

This is unacceptable. I've gone through great lengths trying to stop you from hijacking my browser. I installed a policy generator and followed the instructions to put a policy in. I uninstalled Firefox's background updater tool. I disabled automatic updates in the settings to the best of my ability.

I've gone through everything I can think of trying to stop your forced updates. Its unethical what Mozilla is doing to its users. I even tried to lock policies with admin only authorizations but firefox couldn't read the file anymore when I did that. I did confirm today that the policy file was still working, when Firefox ignored it and shut down my browser till I restarted it. I confirmed that Firefox is blatently ignoring policies.

I just checked and Background Maintnence was installed again when I didn't want it. You're now installing software against my will too? What the hell is going on.

Hello, I am currently using Firefox Beta and I would like to switch to the regular Firefox Release without losing any of my data (browsing history, bookmarks, passwords, add-ons, and settings). I would appreciate guidance on the safest recommended method. Specifically:

Is it safe to install the Release version over Firefox Beta, or could this cause data loss or profile conflicts?

What is the best way to create a full backup of my Firefox profile beforehand?

Should I expect any issues with add-ons after moving from Beta to Release?

Do you recommend enabling Firefox Sync as an additional safeguard, or is a profile backup enough?

In case something goes wrong, what are the recommended recovery steps?

My setup:

Operating System: [windows 10 ]

Thank you for your assistance.

my firefox is up to date (version 149) but I don't have the icon VPN on my toolbar

how can I implement the new VPN (free) in my firefox?

thank you for your help

I bought Mozilla VPN a month ago, and nothing has turned up.

How do I get a refund of my money?

Then I can buy StartPage VPN.

Firefox is really going downhill.
