Important update! On March 14, 2025, a critical root certificate in Firefox will expire. If you’re still using an older version (before Firefox 128 or ESR 115.13+), it’s crucial to update to Firefox 128 or newer to avoid issues with add-ons, DRM-protected content, and other features.

For full details, check out Update Firefox to prevent add-ons issues from root certificate expiration.

I'm getting a message "Your account has been locked for security reasons" when trying to signin into firefox or using my regular signin method on the mozilla website.

When i use the Google option it works on the website (including support page) but in the browser this option is not available. I'm unable to unblock my account. Haven't received un unblock email or something.

For some reason, IDM will not work in Firefox/DuckDuckGo. even though it worked a couple of weeks ago. I contacted IDM support who have tried everything they have, but no change.

Here is the issue: 1. I open Firefox (Duck Duck Go is my default) (132.0.2 (64-bit) 2. I type "vintage sci fi movies" 3. Click on "videos" 4. Pick any movie (example: The Phantom Planet (black and white but this does not matter) 5. In the Choose How you Watch, I click the left icon - Watch Here, and not Watch on YouTube; also click Remember my choice 6. The movie starts but there is no IDM dialogue 7. If I then click Watch on YouTube inside the movie, it switches to YouTube and the movie starts, AND the IDM dialogue pops up.

As I said, this worked in Firefox/DDG a couple of weeks ago.

IDM version is 6.42 Build 23, full (paid for) version Oct 15 2024 The IDM Integration Module in Firefox shows as Version 6.42.22, last updated Oct 28 2024.

Can you assist please.

When trying to use one particular website on Firefox, I get a message that I am blocked because of an ad blocker but I have not turned on any ad blocker in Firefox. How do I find out if an ad blocker is enabled on my Firefox and, if so, how do I turn it off? I have ensured that the ad blocker option in settings is unchecked and even added this web site to permissions but to no avail. Can someone help? Here is the message I get but none of the steps in this message I am told to take show up on my screen:

Adblock Plus Instructions

   Click the AdBlock Plus icon in the extension bar.
   Beneath “Block ads on”, click the large blue toggle next to “This website”.
   Click refresh.

Were these instructions helpful?

I would like to be able to download YouTube videos.

Is there a Firefox add-on that will allow me to download YouTube videos onto my MacMini?

I tried Video DownloadHelper and YouTube Video Downloader and didn't see any action.

Do I need to setup settings a certain way to make it work?

What are the steps to make it work?

Thank you for your assistance.

Today the icons on New Tab have been resized which makes it difficult to see the differences. As seen in the attached images the logo icons have been reduced in size but the generic letter icons have had their outside edges overlain with the border. Not only has the visible area of the thumbnail been reduced but the title for each of the icons has also been truncated. Another thing to note is there is also more vertical space between the icons.

When I looked into this further I found information about the about:config page. As per https://support.mozilla.org/en-US/questions/1338808 I found and edited the browser.newtabpage.activity-stream.newNewtabExperience.enabled key to false. This did not change the icon size.

I also noticed the next key browser.newtabpage.activity-stream.newNewtabLayouts.variant-b So I changed it from true to false. This seemed to work... Hooray!!!

Unfortunately after I closed and reopened firefox the small icons were back.

Please help, the shortcut icons are only helpful if they are readable and identifiable.

I did some googling first and it seems to be an on and off issue mozilla has had with years. Anyway, whenever I play a video (be it youtube, twitter, instagram, even gifs on twitter actually) the video will often mess up and become a chaotic jumbled garbled up mess of green with junk artifacts over the video. The audio will play fine. It's like watching a scrambled TV station from a 90s bootleg cablebox, but green.

This issue doesn't exist in any of my other browsers.

I'd love to continue supporting Firefox instead of Chrome, but this is a persistent issue across the entire internet, so it's kinda obvious I need to stop using Firefox until this is patched. Thanks.

i'm on windows. Suddenly, PDF files that I open have black pages. I checked that the default setting is to open pdf files in Firefox, as always. refreshing doesnt work. Any ideas what is wrong?
