How do I remove the pop up blocker on Firefox for certain websites? I am doing an online course and each introduction for each chapter has a short video that pops up but as soon as that happens Firefox sends a "Critical error" message then the video stops so I thinks that's happening because pop up blocker is turned on and I just dont know how to turn pop up blocker off for specific websites only like this one I am using for my study course. How can I turn the pop up blocker just for this one website so that this doesn't keep happening?

As of 12/9/25, Firefox seems to now prevent Theme add-ons from working if there is a contrast setting configured in Windows configuration. (Version 146.0) Previously, this allowed a very aesthetically pleasing view. I would greatly enjoy having that option again. Thank you.

Svp, comment changer la couleur de la barre latérale ?

La mienne était toujours blanche, mais vient de changer à mon insu pour du bleu ...

Merci de m'aider.

In my Firefox browser, when i try to sign in to Youtube, a window says "there was an issue signing in to Youtube" pops up. None of the troubleshooting articles are helpful for my situation. My Firefox browser is up to the latest update - version 146 on windows 11. Youtube works, but i am prevented from signing in to my account.

I have used Youtube in Firefox before by signing in to my google account, the only thing that has changed was that I went into settings and cleared my browsing history, cache, and cookies. Once those were cleared, Youtube won't sign me in and only shows that error window.

In my Firefox browser settings, I have set Youtube to accept cookies and have disabled adblock for Youtube.

My Youtube account is still accessible using Chrome, but not in Firefox. Youtube WILL sign me in if i use Firefox private browsing. I'd rather not use chrome since Firefox is my primary browser and I'd rather not jump through the extra steps of google sign-in using private browsing.

I do have a Google account with my school institution, but that has never been an issue (expect it won't open google maps for some reason, not the issue here though). My Youtube has always been signed in with my personal Gmail, not my school Gmail. I'm not sure if that's interfering with anything.

To reinstate the main issue: I cleared my browsing data and cookies, now Youtube in Firefox won't sign me in.

I have a new laptop and am using Firefox as my browser. But when I'm on Facebook, go to chats it says that video chat isn't supported by this browser. Does Firefox not allow this? I've tried going to permissions to allow Facebook to access my camera and microphone, but unable to do so. How do I use the video chat feature in Facebook chats?

Reposting until I get help from someone. Windows/desktop. On Google Chrome, any streaming website I used with autoplay enabled would KEEP full screen mode ON after changing episodes. It would automatically go to a new page with the following episode and remain full screen. Why doesn't Firefox have this feature?? I'm seriously considering going back to Google Chrome for this one small feature. Every time I had any streaming service playing with autoplay enabled, I didn't have to manually select the full screen option every time. I am having to stand up and manually click full screen function. Every. Single. Time. Somebody please help me if there's a way to active that function.

Why isn't the Firefox browser supported by many services and social networks? They even state in the warning that Firefox is not supported! Why should users tolerate this?

Почему браузер FireFox не поддерживается многими сервисами и социальными сетями? Так и пишут в предупреждение, что этот браузер FireFox не поддерживается! Почему пользователи должны терпеть это?

A few days ago my saved passwords all disappeared. I have been logging in manually and when I do Firefox asks if I want to save the password and I click yes. The password then shows up in the saved Passwords. But... in a day or so it disappears again. What's going on? I have not changed any settings.

Emojis do not show on Firefox 146 on macOS. I downgraded to 145.0.2 and they do show, so it seems related to Firefox 146.

I have macOS 26.2 running in both test cases.

Also McAffee notification with all these popups stating that my McAffee protection expired yesterday - I have never had a McAffee notification for a virus or pair for protection from them. Popups are happening every 10 seconds continuously! looks like about 20 or more popups describing different problems with 20 digit numbers and letters as a serial number of the problem!
