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

I have a macbook air laptop (late 2010) and have been using the latest version of Firefox browser for browsing. It's one of the few browsers still available. Google is popping up with the message that my browser is no longer supported. Do you have any suggestions about a browser that may work (other than a new computer please)? Will Firefox be coming up with a new extended version that will work? Thanks!

Hello!

I have an imac 21.5-inch (late 2009) on my table with OS X El Capitan running on it. It has the following specifications: 1. Processor - 3.06 Ghz Intel Core 2 Duo 2. RAM - 8 Gb 3. Graphic card with 256 Mb

I have not been able to update the OS to run most recent Applications, and most of it, the web browsers are not updating as well.

What should I do to get through? Thank you.

Bought a new laptop and I had my old Dell laptop transfer all my data to my new HP. My email account went thru fine. But for some unknown reason, I couldn't get my Firefox browser transferred, and I NEED to get my saved passwords from the Firefox Master Password manager.

I think I made a big mistake after data was transferred and I started setting up the HP -- (feel like I got 'tricked' into using Microsoft Edge browser) and didn't know how to get Firefox browser so could get my passwords. So unfortunately, I ended up clicking Download Firefox browser and it was a brand new browser like I was a new first-time user as it was 'blank'....like I would have to start completely over. I have been a long-time Mozilla Firefox browser user. I have been desperately and frustratingly trying to retrieve my Original Firefox Browser that has ALL my info that was so handy and easy to use.

Look at the attachment image. The 'Help' in the Firefox bar won't work anymore. I'm not able to get the Troubleshoot Mode to work.
