Firefox Support Forum

I would like to find the settings for PREVENTING FIREFOX VER 115 ESR on MAC from UPDATING. \

This is because Firefox 115.7.0esr.dmg is (supposedly) the last version for old MacBook Air that lets me watch Netflix on that machine. I want to use Firefox exclusively for that purpose, so that all of Mozilla and Firefox staff can stop worrying about viruses, etc.

The question is: Is there such a setting on Firefox 115.7.0esr.dmg that would let me accomplish that. I CAN follow long-winded & complicated instructions to the letter, and as long as these instructions are correct and complete, there should be no problem. If mission control for NASA's 1977's Voyager can still communicate and extend the useful of the Voyager probe, then I figure that you understand what it might take to keep a MacBook Air from 2015 going. In other words: As long as it works, it's worth it to keep it going.

If Mozilla's mantra is: "Lets destroy everything older than 4 years", then you will not understand the issue.

Does anyone on Support Mozilla know the secret magic software words to do this?

After a cat attack on the keyboard, Firefox is not allowing the site-specific fonts to be selected, instead over-riding with the generic font. The site is displayed correctly in ALL other browsers, including Safari, Opera, and Chrome, and in the editing app., BBEDIT. There is some fundamental font over-ride that is happening ONLY in Firefox. How to correct this?
