In Firefox, and only in Firefox, I get 'Failed to verify your identity' on these sites. I have updated MacOS and Firefox, rebooted, tried a different DNS, and disabled all of my extensions. With extensions disabled I don't get the error, but the login site won't accept my login at all. See the attached image. I can't think of anything else to try.

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.

Helo team, I think I hit some key and firefox settings changed. I see squiggly characters in menu options, bookmarks etc.. Web pages load all right. I tried uninstalling/reinstalling. It did not help. Please see attached screenshots. I use a Mac M1 mini.

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.

In recent weeks when I open my Macbook and go to https://meet.google.com, the page that loads says "404. That’s an error. The requested URL was not found on this server. That’s all we know." The issue is only on Firefox and not Chrome or Safari. When I see the error page, I look at the URL and it has the word "unsupported": https://meet.google.com/unsupported?meetingCode=landing&ref=https://meet.google.com/landing

So I dragged firefox to the trash, reinstalled and the issue persisted. I do not have a VPN. I'm using my own Wifi at home. If I switch to my desktop computer (m2 mac ultra) and go to the same Google Meet URL, I don't get a 404 error on firefox, however no one can hear my microphone any more as of 1 month ago, when I didn't have this issue in the past and I've done everything that everyone has told me to (in order to fix it) and nothing has worked.

Laptop: MacBook Pro 2021, MacOS Sequoia 15.0 Firefox: 13.0.1 (64 bit)

I use a program called "URL Manager Pro" on the Mac to manage my bookmarks in all my browsers. Double clicking on a bookmark icon in URL Manager can open the URL in a new tab, the same tab, or a new window depending upon how I set the preferences in URL Manager Pro. This works fine in Safari. However, in Firefox, the website opens in a new tab regardless of how I set my preferences in URL Manager.

The author of URL Manager tells me the issue is a problem with how Firefox deals with AppleEvents. It's very annoying to accumulate so many unintended new tabs and then manually close them. Is this fixable in Firefox or is there a work around?

Thanks

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?

Hello,

I checked the troubleshoot and gave all the necesarry permissions on my Mac for Google Meet to use my screen (allowed audio, video and screen recording). Nevertheless, I cannot manage to share my screen on Google Meet. As shown in the screenshot, it offers the option to share my whole screen (I cannot select a window or a tab...) but for my audience neither this is working.

Could you please help me fix this?

Many thanks in advance!

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.

For example: When I'm working on a Washington Post (LATimes) crossword puzzle, the internal link to "settings" doesn't work on Firefox, but it does on Safari.

For example: When I'm on the website for my apartment building, the internal links to "maintenance requests" and "make payments" work on Safari but not on Firefox.

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

I have been noticing that Firefox browser is being manipulated to obtain confidential information from users.

Is Firefox doing anything to stop this? The crooks who are most likely military and Others affiliated with the government are surreptitiously accessing US Citizens computers and silently obtaining credit card information, banking, Venmo, Zelle Apple Cash, etc. and ROBBiNG citizens.

This is no joke. is Mozilla doing anything to protect their browsers from these hoodlums and corrupt government officials and there hired contractors?

The people you trust are not to be trusted.

I wanted to upgrade and update my Firefox to the latest version. Encountered some errors so I uninstalled the old version and reinstalled Firefox' latest version. Now all of a sudden all my Add-ons / Plugins / Extentions on the latest version of Firefox for Mac OS is gone...

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.

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...
