I have a Mac that you are threatening not to serve any more. I read about your Extended download. If I do not download this Firefox Extended upgrade, does this mean that my Mac will not be able to browse and read web pages, etc., or will I not be able to open any URLs?

Also, I am having problems with some downloads in Acrobat not displaying the proper font type and size and kerning, but it downloads and prints those documents in the right dimensions. Is this a Firefox problem or an Acrobat problem or a computer problem?

I should mention that I am just about out of memory on this old computer and do not wish to add more downloads at this time, until I can get some memory cleared out, which might take me awhile.

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.

I have been blocked from making payments from the billpayer on my accounts with credit union. Even my Gmail says I am using an outdated browser but my settings history says it is all up to date. Bills are due and I need help in clearing this up. I am on Windows 7 Home Premium.Is there something further I need to adjust?

Up until version 141, the difference between 32 bit and 64 bit Firefox installers wasn't noteworthy, though it has clearly been slowly increasing overtime. However, starting from version 141, the difference between them doubled from 5MB to 10MB, meaning a nearly 13.5% larger installer for the 64bit version than the 32bit one.

Why is that? What happened? Are there are feature differences that would warranty such a large gulf in their installer sizes? It's the AI isn't it? 32bit users were spared the bloat of the AI.

I also see that starting from 115.16 Firefox suggests users that aren't on Windows 7-8.1 or MacOS 10.12-10.14 should use other versions. Given both x86 and Windows' immense reputation surrounding backwards compatibility, is this really a concern? Is there REALLY something supported by Windows 7-8.1 that wouldn't function on 10?
