Firefox Community Forum

I'm suddenly getting 30-50 popups a day from the above websites telling me that there are all sorts of trojans and viruses on my computer and telling me to "click here" to fix them. I WANT TO BLOCK THEM... as I'm quite sure they are scams. I just delete them, but they keep coming back How do I block them? Just got another one that says "Mozilla Firefox -- Trojan virus detected! Scan and delete with McAfee -- click here: via d14an00hubcc73a1lt40.quickupdevice.co.in". ...and I just got two more.

Please tell me how to stop this stuff. Thank you.

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.

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

I log into a secure web account, use user ID and password, go through 3 rd party verification and gain access.

When I logout it takes back to the sites Home page.

If I decide to login again by using the login icon the website immediately logs me backin with No requirement for user ID, Password or 3 rd party verification.

I am trying to determine is Firefox holding this information (User ID, Password and Third party verification code) and auto logging me in or have I not really logged out.

If I completely close Firefox this does not occur.

Hi, I just installed the latest update (I think it's 136.0.2). I guess I skipped some/several versions. Suddenly my main menu isn't workin anymore (clicking it with the mouse, that is) There is some overlay which I can't find out, how to remove. Even the Minimize/Maximize/Close buttons don't have any function. Luckily I can still access the menu via keyboard shortcuts. How can I remove that overlay bar ... or did I catch some malware ?

using (file, edit, view) type page and would like to change the bookmarks dropdown menu i would like to get rid of: Bookmark current tab, seach bookmarks, bookmark all tabs and the separators i don't use tabs, i just open new windows if i can't delete them, would like to be able to move them to the bottom thank you

Unable to find list of blocked email addresses. Went to "settings" / "Security & Privacy". No luck. I have no problem in deleting addresses. UNBLOCKING is eluding me.

As my title says, i manage to make my Tabs length to be as long as possible, i even manage to make it when i scroll with my mouse wheel one tab at a time, but after accepting to update Firefox, my tabs shrink when i play a video! or when i open a new youtube video in a new tab, that is only on youtube,

So how do i stop this? i do not need my tabs to shrink when i play a video

Hi, I'm working with a website sponsored by the American College of Surgeons. Some of the parts of that website are blocked by Mozilla. Is there a way to trust that website completely?

Hey everyone, I need some help with a puzzling issue. I've noticed that a website (https://storiescastle.com/coco-miguel-and-the-amazing-alebrijes-story/) I'm working on functions perfectly fine when I use Google Chrome, but when I try to access it using Mozilla Firefox, I encounter a '404 error' or sometimes the layout is broken with images displaying incorrectly. Can anyone shed some light on what might be causing this discrepancy? Your insights would be greatly appreciated!
