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.

So I understand this: https://support.mozilla.org/en-US/kb/xframe-neterror-page and the reason it exists, but I need to find a way to turn it off because it's literally blocking me from accessing the Library of Congress webpage inside the same browser for my job. It's not a malicious site, but I can't figure out how to tell Firefox to stop blocking it as if it was a malicious site.

Help.

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)

Last week my usually reliable 'Thunderbird 115.8.01 on iMac 10.13.6 has suddenly gone haywire.

* In the folder pane, multiple folder duplicates reappearing even after deleting them. (See images) * And when I delete messages, they appear in the trash folder, only to disappear and repeatedly reappear - back into the message INBOX. * Also, after making a change in the Notification section to turn off the notice sound, and although the sound turned off, so did the auto-disappear function. Now I have to manually "close" each and ALL notification notices one-by-one. The new problem is: now the notification option section has disappeared in settings. (No image for this one. Nothing there!) Bug? Or something else?

Please help. P.S. I ran both of my antivirus programs twice. Each over different days and both declared' my system clear and clean.

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!

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.

Up until 6 months ago I was easily able to access all my bank accounts on line using Firefox. I can still access others but not Capital One 360 on line banking. When I try to access Capital One I just get the message that " there has been snag and to try again" which does not work. So I can access my Capital One account only thru Google Chrome. Capital One says that the reason is that Firefox does not update their security setting to the level they require. Can anyone tell me if this is the problem or if there is some other reason why I can no longer use Firefox to access this account.

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 have latest version of FF and MacBook Pro 10.9.2. Recently had major keychain problems and worked a lot with Apple to solve them. Now all is well but…. I am now frequently asked to enter my master password when I am in FF; they has never happened before. For example, when I go to Amazon, a window opens asking for the master pw. In some cases, this is not a big deal because I can cancel the request and my keychain will get me into the site. In other cases, my keychain does not work if I cancel the request for the MPW and I have to enter my access information. I asked Apple support about this, and they said to contact you.

I cannot pin the extension to the toolbar. The extension is not shown in the puzzle icon dropdown, and it is not in the overflow. Please add an automatic pin to the toolbar when a new extension is added! How do I pin it now?

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...

macOS. Firefox is running. I enter: open -a Firefox --args -private-window "https://apple.com" (in Terminal or Automator) which I believe should open apple.com in a new private window, but although the focus change to the already open Firefox window, a new private window does not open. It does work (apple.com opens in a new private window) if Firefox is not already running, but I thought the -private-window argument is supposed to open a new private window whether Firefox is already running or not. What have I got wrong?

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.

i just upgraded firefox for Mac OS to 115.23.0esr (64-bit) and now I cannot log in to my bank account from this desktop. Safari works on the iPhone but I NEED FIREFOX ON THE DESKTOP IMAC (Sierra 10.12.6) There seems to be NO INFORMATION ON YOUR "ASK A QUESTION" PAGE ABOUT THE UPDATE

Hello support-type people,

I have a specific website that I have active in FireFox called myNoise.net. It allows me to generate background noise generators to cover-up the distracting noises from my neighbours when working at home on my desktop computer. The audio on the website worked the last time I opened Firefox ~2 July ... but today, when I opened the browser, the audio no longer works. I cannot get the website audio to load at all - I added the website to additional exception lists & shut down some content blocking extensions, but no joy. The website was already listed in multiple exception lists & I do not know or understand what change(s) occurred with the browser that would prevent this site from properly functioning - since it literally worked a week ago. I would appreciate any assistance and/or guidance with this issue, otherwise I will be eliminating Firefox as one of my browser options. I have provided a screenshot of the site that shows the perpetual "now loading" screen. Thank you.

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

I have my Mac and thunderbird set to auto-update, so I am not sure where the culprit lies. But my system did a Mac update and a Thunderbird update both recently. I'm now on Sonoma 14.3.1 and Thunderbird 15.8.1. When I started thunderbird it spun for 10 minutes. I thought it was locked up initially, did it again and even tried starting in safe mode. But after about 10 minutes, it eventually stopped. Problem was all my calendars won't display. I can add or remove either. The interface is barely responsive, and it crashes after a few minutes. I started Thunderbird from the command line to see if I could monitor the errors. I get about 100 of the following:

2024-03-10 14:06:22.361 thunderbird-bin[17189:518538] Rethrowing (from nts_ValueForProperty:) NSInternalInconsistencyException: Unhandled error (NSCocoaErrorDomain, 134092) occurred during faulting and was thrown: Error Domain=NSCocoaErrorDomain Code=134092 "(null)" CoreData: error: Unhandled error occurred during faulting: Error Domain=NSCocoaErrorDomain Code=134092 "(null)" ({ })

Anyone having similar errors, or any ideas on a fix?

Thanks,

Roberto
