Firefox Community Forum

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...

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?

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.

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!

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.

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)

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 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.

macOS Sonoma, M1 Not sure when this happened, but I can no longer change my zoom level in settings. As you can see in the screenshot, the - and + are both greyed out and I can't use them. Using cmd+ or cmd- doesnt work either.

When using Google Meet in Firefox browser, I am only able to share my window, not my screen. When I choose "share screen", it says I must change my permissions - but my permissions settings have not changed and this is a problem I have started having only in the last few days.

I do not know where I am supposed to change these permissions settings.

I have checked my permissions in settings > privacy & security > permissions - there is nothing there about screen sharing.

I have checked my permissions in padlock > connection > more information > permissions and the only options I have for screen sharing are "always ask" (default), which is set. The only other option I have is "block" which is not set.

My Firefox browser is up-to-date.

Can anyone help? Thanks!

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.

What?: Using screensharing option in Google Meets stuns computer. Where?: Version 132.0.2 (64-bit) macOS 15.1 Steps to reproduce: 1. Open Google Meet meeting. 2. Click Share screen. 3. Select "Use operating system settings" - this is the only option available 4. Click Allow. Current behaviour: The screensharing feature stuns the computer, showing the loading mouse cursor for ever. I can't select the screen I want to share. The computer is unusable even after quitting Firefox. The computer should be restarted. Desired behaviour: The screensharing works normally.

When I download an attachment from Gmail, I would like to just download it. However, Firefox now opens the attachment in a new tab before I can download it. Is this new? Is there a way to turn this off?
