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.
