Firefox Community Forum

Starting a few weeks ago, firefox would not load any accounts via https://login.microsoftonline.com/ one one of my Macs.

I was running the latest version 121.xx on MAC 12.7.2

Nothing would fix the site issue, so I tried re-installing and refreshing Firefox. Followed all the troubleshooting steps.

Now firefox is completely broken. Tried creating a new profile. Running in safe mode, etc.

It sometimes will load pages, but extremely slow. But generally is unusable.

Firefox works on my other macs just fine (Profile uses sync with those machines)

Safari and Chrome work perfectly fine. No malware. No ISP issues. No firewall.

Please advise a fix or I guess I will delete everything firefox related.

When I click on a link on some websites, the link opens with no trouble. However some links don't open, just show the url. If I copy the url and paste it into a new tab, it then opens. How do I fix this? The links are from reputable sites.

we have 2 imacs here:

imac A just had OS catalina installed and firefox is shown as up to date running v 115.15. However, while it loads the apple tv website the site remains unresponsive to input.

imac B is runnning OS Sonoma and firefox is shown as up to date running v 130.01. There is no problem with the apple tv site, which responds to input.

So: why can't I update firefox to the latest version on imac A and why is the apple tv website unresponsive when it works on imac B running an older OS?

I am unable to use Fidelity Investments using Firefox Version 134.00. Just says "Service Unavailable" this site always worked with Firefox in the past. No problem when I use Safari.. Anyone else having this problem.

Whenever I go to a Google page (tested on Google.com Docs, Sheets, Forms) the page crashes. The issue started sometime around this afternoon.

the past 4 producers have told me they cant hear me on google video chat (https://meet.google.com/) i'm on firefox. it worked fine forever, then no one could hear me and i reported it a bunch to google and firefox because it was clearly a firefox issue. someone on their end fixed it. it was working for a while. now its back to people not being able to hear me again when its not a me problem. i keep reporting it and its not being fixed. how do i escalate this? why does this keep having every few months?

zero issues on google chrome browser while video chatting. zero issues on zoom. its firefox's google videochat that people cant hear me. feels like a repeat issue of what happened months ago when the issue wasnt with me. please fix this again

We tried 2 different computers, but two different users. Type in the user name and the password and it looks like it will start up, but then returns to the login paged.

As of February 13, 2025 the front page of the Washington Post website does not load correctly in Firefox 115.20.0esr in Mac OS 10.13.6. The problem persists even in safe mode. Thank you.

I received an email suggesting that I update my Firefox or I would lose syncing function. I have two computers. A fairly new iMac Ventura 13.6.8 running Firefox 123.0 64 bit which it says is up to date. But I also have an older iMac OSX 10.11.6 El Capiten running Firefox 78.15.0 ESR. I can't update the OS or Firefox on the old computer. So if I do nothing - will I still be able to sync on the newer Mac. I'm not too worried about the old one - I don't use it much for browsing - more for documents. Thank you. David Rimell

hello all,

I'm running Firefox 115.18.0esr For a month now, tabs have crashed constantly. That is, *every single tab* crashes sooner or later and usually it's sooner. It's making Firefox unusable.

I know my desktop is old and my OS is considered obsolete, but still, I'm a fan of Firefox and want it to work. I'm running OS 10.13.6 (which I can no longer update) on a iMac mid-2011.

Any advice much appreciated.

When I updated my MacOS Sonoma to Version 14.6.1, I was unable to open the Firefox App.

When I click on the icon the dot below shows that its active, but no windows appear. I tried doing "Show all windows", but the screen just says "No Available Windows".

I'm using firefox 97 on mac. Whenever I copy and paste an image from firefox, the image comes out desaturated as if it is using the wrong color profile. I tried changing the gfx.color_management settings without it improving. The images look fine and are the right colors in the browser, however, the issue only happens when I copy and paste images. Firefox behaves like the color management is disabled (set to 0 in config) but ONLY when copying and pasting images.

I do not have this issue with other browsers such as chrome.

Microsoft Excel is no longer listed i Applications as download option. All files downloaded automatically are stored as Microsoft Word files, not just excel files. I can change individual files manually to .xlsx which is a nuisance, but this also happens with Zip files (7Zip) and I am at a loss as to how to change them when they are downloaded as a Word document.

This does not happen on a newer MacBook Pro, but I need it to work with the older version. The older Mac is MacBook Pro 9.2 with MacOS Catalina Version 10.15.7 Firefox is version 103.0

My MacOS is 10.13.6 (cannot go higher on this machine). Since update to 15.119.0esr, embedded map graphics are no longer showing. The map graphic sub-window instead shows "Sorry, we have no imagery here" in several places across the map. I am getting the same for multiple websites, including the location maps in Zillow.com . Google Maps works fine, and I think the problem is isolated to maps embedded in pages. Did not have this issue last week, prior to updating to 15.119.0esr. This is SO BAD that if it's not fixable, I want to revert to 15.118...

All my other browsers work fine but since April 4, 2025 Firefox won’t work at all. Websites won’t load. I have tried to clear my cache & cookies, I have checked my connection settings, I have checked for malware, I have turned off all my extensions and I have completely restarted my computer several times now, nothing has worked. I also did trouble shoot mode & reinstalled Firefox (though I will admit I maybe didn’t do this step properly). I refreshed Firefox. Why is it not working? What happened? I don’t know what to do as I don’t want to lose all my bookmarks and passwords that I have yet to move over to my password manager. Please help.
