Firefox Community Forum

I'm on an older, unsupported operating system (MacOS 10.14 Mojave) and am currently using Firefox 115.36.0esr which for the most part works fine. But there are increasingly websites that complain about having an outdated/unsupported browser and won't let me log in or whatever. For some sites I've solved the problem by using the Opera browser, but I've grown accustomed to Firefox, so......

There are a couple of options (that I know of) with browsers based on Firefox: Firefox Dynasty which has now become Firefox Momiji and Pale Moon.

I've given Momiji a quick try and function-wise it seems more or less like the regular Firefox, but does anyone know how safe it is to use? Both in regards to whoever is behind it and as a browser in general? I know nothing about Pale Moon. In addition to working with most current websites and be safe it should ideally be compatible with the current (115.36.0esr) version of the normal Firefox so that I can transfer all my open windows, bookmarks, tabs, passwords etc.

How do I change a profile folder's name without causing any problems? I'm on a Mac.

I know I can change a profile's name for internal Firefox use (by going to about:profiles in the URL address section of the browser), but the cryptic folder names remain the same. I've read that you should never change a profile folder's name directly (inside ~/Library/Application Support/Firefox/Profiles/), so is there another way?

I run both the standard version of Firefox and the developer edition on the same computer, so it would be nice to immediately see which profile folder belongs to which Firefox version by their names.

Mozilla Firefox desktop : As at evening of 22nd May 2026, UK time, Firefox will not interface to Aol email. Gives " We can’t connect to the server at mail.aol.com ". Connection was fine earlier today, & as I know of no Mozilla changes, suspect this is a change at the AOL end. no longer permitting access to Firefox.  ?? Other browsers do connect, hence not an AOL outage.
