Firefox Community Forum

Hi,

I'm running macOS High Sierra 10.13.3. After Firefox automatically updated me to the Extended Support Release 15.42.0esr (64-bits), some websites no longer load. The page loads blank or the site never finishes loading. Before the update, the previous version of Firefox ran very well on this Mac all the sites I use opened normally. My questions: 1. Is it possible to revert to the Firefox version I was using before this

  update? If so, which version should I install, and what is the safe way to
  downgrade? I've read that downgrading can affect my profile.

2. If reverting is not recommended, is there any setting within ESR 115 that

  could restore access to these sites?

Thanks in advance.

i find it amazing that firefox does not recognize that my bell email is legitimate... for a while i blamed MY computer as it is older not so... it comes down to the fact firefox is constantly showing problem loading page... for years i have been receiving ekos surveys again there it is problem loading page thus this morning when it stated problem loading page i overrode it & opened the survey page & completed the survey my first in months... it comes down to firefox... when i am comfortable i accept when not comfortable i ignore & move on...

I want to install another language. Language selected, clicked ADD. Firefox sticks at "Downloading" with marker moving left and right. Why? And how do I install the language I want?

Hello,

For some inexplicable reason, when I visit any Wikipedia page (as of Thursday 8th October 2026), the pages display with a huge oversized font that also impacts the format and layout of the page in my browser. I have not made any adjustments on my PC to increase font display size. Wikipedia is the ONLY website that displays in this manner.

I am running Firefox 115.42.0esr (64-bit), which appears to indicate Firefox is up-to-date on my Windows 8.1 desktop PC. Please note that I am still running Windows 8.1 on this device out of choice.

I reported the fault initially to Wikipedia itself, and the response is that any fault is at my end. I have visited the same Wikipedia pages via Chrome Version 109.0.5414.168 (Official Build) (64-bit) and the pages display normally.

I have attached a sample screenshot to illustrate.

Any ideas how I can resolve this issue please?

Many thanks - Dean

I have used Firefox as my browser for many years now. But I am having difficulties with my Apple Mail App and have tried to set up email account on Gmail. Gmail/google have message saying my Browser, ie Firefox, is no longer supported on their platform for email. I also saw a message in Firefox, saying my OS 10.13.6 is no longer supported by Firefox.

questions: can I still use Firefox if my OS stays the same (ie I don't update computer OS, not sure if I can anyway) is there a way to update Firefox to work with GMail?

Am totally confused. thanks

I switched to Firefox from Chrome as my computer is too old (OS-High Sierra) and wouldn't support Chrome any more I've had to restart several times and each time I reopen Firefox, all my tabs are deleted. How can I prevent this and/or restore my tabs?

Had to reinstall Firefox on laptop & now Home Button is missing from menu bar (or bookmarks toolbar - I'm not sure which). Everything else is back to way it was (bookmarks, extensions etc.) So, I found & followed steps to drag & drop it but it ALSO is missing from customize toolbar page. On my desktop using same Firefox account Home Button IS displaying where it always has been. Is there a way to CREATE a "new" Home Button to drag & drop?
