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.

Doing any search brings up result page that just has my query and a search magnifying glass - not the search results as expected and working on Mac.

This is 2 days old only as of 11 June 25.

Crying here as I depend on it sooo much; this is a work PC and DDG is my go-to for research.

Hello I have a problem, namely at work when I click a link to a photo, the Firefox browser open a new tab but displays nothing (white background), but when I hover over the link and click enter, what should appear is what should be there. Where in the settings can I change it so that such links do not have to be approved by enter.

Dear Firefox team, I have one question only.

ARE YOU FUCKING INSANE? Can you STOP bombarding me with the notifications? This is MY DESKTOP, this is MY PC, I DON'T NEED this shit.

For anyone who would like to help:

No, there's no such option in settings. No, removing updater physically does not stop pop-ups. No, there's nothing in about:config to shut up the updates.

For Firefox team:

No, your updates ruin the browser, more and more, I think I'm about to switch to Pale Moon instead.

Hi, I am curious to know why I can't completely remove the Dutch language in the language settings. When I installed the browser it was automatically set-up to Dutch - a language don't speak - then I was able to add English but some functions like spelling corrections are still in Dutch. I would like to get rid of it. I have the same problem with German on another computer. Thanks!

Using Firefox without Internet in closed environment.

Could you please disable Update Check with fake notification "Update Available - download now"?

Thank you!

Hi, I already know that Firefox, especially LibreWolf, is probably the best browser along with TOR and Brave about protecting against fingerprinting. However, after reading this paper https://arxiv.org/abs/2506.00719 about browser fingerprinting via WebAssembly I am wondering if and how Firefox, LibreWolf, can protect us against it. I already read this https://support.mozilla.org/en-US/kb/firefox-protection-against-fingerprinting, but I could not find any reference to such protection. Thank you

Hello. I just have a general question. I have read about it a little but I get mixed info. Some say yes, some say no.... So, is it possible to get a virus or malware or any of that spyware stuff on mobile phones like you can on a computer? Particularly Android phones. They have all these anti-virus apps and stuff you can download saying they're designed specifically for Android mobile devices but then I have read articles that say that the Android operating system is not the same as, let's say, a Windows PC operating system so it's not possible to download spyware onto it. I'm just curious and appreciate any info. Thank you!!

hi, i cant find an option to dismiss the new sidebar. it's pointless and i can switch all the buttons off, but now there is just an empty space at the side of my browser. very annoying. i hate the AI integration and i will not be recommending this browser to anyone in the future because of it. I have spent years convincing others to make the switch to firefox, but what's the point if it ends up just as toxic and useless as every other browser. disappointing.

Hello:

When I signed into my computer this morning, a pop-up asked me if I wanted Firefox to update. I let it do that, and then a pop-up came up letting choose among some photos and art for a desktop background. It even let me upload a photo of mine. I chose one of yours, now I can't change to any other photo I have on my computer. Please help.

Thank you,

Cynthia M.

While using Debian 12 on two workstations running version 136 the "update available" would appear on the screen and remain on the screen with no option to update or cancel.

Because this happened on 2 Debian 12 workstations, i would like to know if this is a known problem as I updated 139.01 an the issue continues.

You will noticed in the screen capture update available has no options other than "learn more"

I've been having issues with search bar suggestions, in particular a site which used to be in my bookmarks but has since been removed. I always use Firefox in private mode, so no history is saved either. In my search bar suggestions I allow bookmarks since there are several sites I often visit. (Also please don't visit the site, it's not a good one) Even so this particular site keeps showing up in the search bar suggestions, with no other trace of it elsewhere. I hope I could get some answers to this issue

Images in order - empty browsing history, no bookmarks of the particular site, bookmarks working properly, the search suggestion, and my search settings

Got upgraded to windows 11. Very frequently when I try and open a tab with Firefox, I can't open it. It's running, but stuck minimized. I can see the little mini version of it when i mouse over the shortcut on my taskbar. I've followed instructions of people who have also had this problem. I've deleted and renamed xulstore. The only thing that ever solves the problem when it comes up (which is often) is trying to uninstall firefox and then refreshing it instead.

This is kind of untenable though because I'd really rather not reinstall my plugins every day and get logged out of everything. What should I do to make this problem go away forever without constantly having to take time and reset firefox
