Upon upgrading to v140.0 on macOS Sonoma 14.3 (23D56), YouTube no longer renders.

All add-ons (ad-blockers, development tools, accessibility tools, etc.) were removed and still the same non-rendering as of this evening June 24, 2025.

Using Windows 11 just reloaded on new hard drive (Solid State). Old hard drive took up smoking. This error does not happen on any other site and did not happen before.

I have no ability to connect to the IRS.gov account log in page. When attempting to do so, the link reverts to a maintenance page, with the hopeful message: "We apologize but there seems to be an issue completing your request. Please try again in a few minutes." An error URL is also attached.

This is not a new problem and has been ongoing for over a year. I have found several messages in the Mozilla support system describing the exact same problem from different users. There does not seem to be a fix that has been found. The information that I have found regarding the IRS website does not suggest that it will only work with Chrome or Chrome based browsers. But I can easily use the site with Edge.

There are several sites that I am unable to access with Firefox that force me to use Edge. I understand that Firefox has its security idiosyncrasies. But As this number climbs, and to include what are public facing government sites, a question I will soon ask is why use the Fireofox browser?

Hi,

I recently set a custom background image for the Firefox new tab page (and possibly the homepage), but now I’d like to remove or replace it.

I’ve already tried:

   Going to about:config and enabling the following:

       browser.newtabpage.activity-stream.newtabWallpapers.customWallpaper.enabled → true

       browser.newtabpage.activity-stream.newtabWallpapers.ui.enabled → true

   Searching for a gear icon or any UI options on the new tab or homepage – but nothing appears.

I also checked about:preferences#home but there are no visible options to manage background images.

How can I remove or change the custom background image? I’d appreciate instructions, config paths, or a file location where I can delete the image manually.

Thank you! p.s. I'm stuck with a background image that makes my shortcuts unreadable and it's driving me crazy. 😅

I am on medical marijuana and I cannot use the site because email says I needs a new browser. Without this new browser I cannot get anything from the Medical Marijuana. Everything from the state goes through the email system. There Is a problem with my medical card. It is not working. I have been trying for over a week to get the code I need to open the site and order a new card. I was told that the fasted way to do this is to go through Lost or Stolen card. Cannot get where I need to go because of my email needs a new browser. I am on loop and cannot get off the merry-go-round without help, so please help me.

When I tried to go through, google wanted me to use a new address. bonniegeo346, however [email removed]@ gmail works. Does it matter which I use?

Previously, when printing a website, you could select the text on the page and then click print and then there was an option (Print SELECTION) that would allow you to print only the highlighted text.

I cannot find that option on the modern firefox print window/dialogue?

I've tried to book flights repeatedly online and Firefox is preventing it. How do I nknow? because I went to Safari and the bookings went straight through. Same bookings, same sites.

open Walmart, for instances I keep getting these pop up saying I have 20 virus etc. get this download. How do I stop this? It is non stop on anything I try to see.

Unsure if this is correct category... Years ago when Firefox was in it's infancy - Firefox settings used to allow much more power/control over cookies & how you deleted them. You could actually display & select individually ones you wanted to delete. Now Firefox has it's own Interface 'utility' and only allows you to delete 'groups' of cookies based on their App name. I was looking for the location / name of the dataset which is used to store cookies - so I could delete them more finely. Or is this in some sort of special format which is ONLY accessible thru Settings. I see MANY Cookie add-ons, mostly dealing with auto-responding to cookie prompts. Actually as of this writing - I am trying one of these.

I WAS ON A SITE AND IT BROUGHT UP THE COOKIE PAGE FOR FIREFOX TO PROTECT ME FROM PEOPLE OR COMPANIES FROM TRACKING MY BROWSING AND I COULD NOT GET BACK TO MY PURCHASE PAGE APP ACOOUNT I WAS ON. SO WHAT HAPPEN & WHY DID THIS COME UP?

For the last few months I've been getting slow responses with online applications. When I switch to chrome, it all runs at a normal pace. Specifically with " The Customer Factor"
