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 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.

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.

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.

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

I frequently try to save pages as PDFs. When I print the page directly to a printer, no problem. When I save the PDF, it's usually munged and not a valid PDF file (very small or 0 bytes). Example URL: https://www.nytimes.com/2019/07/01/science/bacteria-microbes-electricity.html

Makes an empty PDF while when I do Print and then Save as PDF. I'm on Apple OS 10.13, using Firefox 67.0.4. This problem has been with us for a while (> 1 year I believe) and happens on all my machines.

Unable to open this site from Mozilla on Mac book but it opens in safari. What may be the reason?

When I try to access a movie or get further info by clicking the movie's pic, I get this message, despite deleting my cache and cookies, closing and opening Firefox, shutting and opening my MacBook. Any suggestions most appreciated!

That shouldn't have happened.

It looks like something went wrong on our side. Let's find you a great video to watch instead.

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?

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?

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".

Aliexpress.us will not load - Firefox cannot/will not redirect. Cleard cookies/catch, etc.- put exception for website in privacy. No change. Safari loads website just fine. Any ideas? OSX 15.2

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...

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.

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?

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.
