Firefox Community Forum

The operating system on my iMac is still the same version as when I bought it about 10 years ago: macOS High Sierra Version 10.13.6. Since I recently downloaded the latest version of Firefox, left mouse clicks no longer work in Substack pages. How can I download and install a version of Firefox that will go back to working for me the way it used to? I'd rather not update to a later version of the macOS operating system. I suppose I can if I absolutely have to, but I haven't been able to figure out how to do that either.

UBS Digital Banking is asking me to update my Firefox browser (140.15 Oesr), even though it is up to date according to the information on the Firefox support page. This version is no longer compatible with UBS’s technical requirements. What are my options if I wish to continue using Firefox rather than another browser? Thank you Luc

I have a MBP running OS Sierra (10.12.6).

I've exported all my bookmarks & Passwords ready to import them later.

I've downloaded the extended 115.40 version of Firefox. I've deleted the 'old' versin of Firefox and opened the esr and I see the bookmarks are still there... so what did I do wrong?

I'm still getting the 'This browser version is no longer supported' Error

Thanks g

Hello! I'm on Debian, and there Firefox ESR is the default browser, it is now basically unusable as it is so out of date that Cloudflare Turnstile no longer works.

This is a major problem.

I have opened a ticket over at Cloudflare, but they have not commented at all on the problems: https://community.cloudflare.com/t/turnstile-not-woring-for-the-last-few-days/939637

Thank you for your time.

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?

I downloaded the Firefox ESR for my High Siera OS, but I still get the message that Firefox is no longer supported, Why??? Just let me know what I need to do so I can use the browser without worry.

I have a MacPro 2012, updated to the max. I'm retired, and by budget does not allow for a new computer.
