I just started having an issue with my browser where every time I tab out of a tab playing media, the pop-out video appears on its own. It's quite annoying. How do I stop this from automatically happening?

TikTok might not be working due to a few common reasons like a poor internet connection, server problems on TikTok’s side, an outdated app version, or too much cached data. Sometimes, the app might crash or fail to load videos properly. Restarting the app, clearing cache, or updating it usually helps fix the problem. bold text

Can't use YT picture in picture mode on Firefox when logged into my YT account. When I enable picture in picture on a video and scroll down to the comments, picture in picture mode turns off as soon as I scroll past the bottom of the video.

Happens only when I'm logged into my YT account on Firefox. Logout, it works. Logged in on Edge, it works. Logged into my second YT account on Firefox, it works. Only doesn't work for this one account.

Attached images if that helps. Last image shows exactly when picture in picture mode turns off when I'm scrolling

It says on https://support.mozilla.org/en-US/kb/about-picture-picture-firefox#w_keyboard-shortcuts that the hotkey to toggle `PiP is CTRL Shift ]`. When I play a video it shows the PiP button, but the hotkey doesn't work. The other PiP keys like seeking and volume work. I'm on Fedora 41 with KDE 6.3.3 & Wayland.

My Firefox browser used to open in full screen but for the last 2-3 months it only opens about 2/3 of the screen. Pressing F11 does not work. It only works if I press the centre icon in the upper right corner of the browser.

This happens every time I open the browser. I have looked on Google but nothing works for me. It used to work fine and I do not know what has happened. Another browser works fine but Firefox does not. Any assistance is greatly appreciated. Kind regards

Only hours after my previous use of the picture in picture function to watch YouTube via the mobile site on the app browser, the function suddenly stopped working.

It would play the videos when I was in other tabs, and with the app itself closed. However, as soon as I opened it as a picture in picture window, the video paused and refused to restart playing.

This far, I have:

• cleared the cache
• force quit the app and restarted
• double checked that picture in picture was enabled (it was)
• made sure the app is up to date (it is) and compatible with my phone (it is)
• made sure the Video Background Play Fit was still enabled and up to date (it is)

None of these issues has resolved the issue. As the issue is specific to the play to play function, and is not effected by closing the browser or switching tabs, I believe it is an issue with the function, not the site.

the pic in pic feature doesn't work. When I click the icon to go pic in pic Firefox opens a new full screen window with the video. I can't see any way to toggle it to be a small screen at the edge of the screen I'm working in.

Please advise.

I loved the picture-in-picture mode. However, when I closed the picture in picture mode, the video automatically stopped. Is there any ways where the video still plays even after I closed the picture in picture mode?

While watching a video in full screen mode, the screen periodically darkens for 2-3 seconds, after which the video continues, during the darkening the video stops and there is no sound

Hi, I've been receiving the following rejection message as follows: jino.ru rejected your message to the following email addresses:

postmaster@pop3-server-spam.org The address you sent your message to wasn't found at the destination domain. It might be misspelled or it might not exist. Try to fix the problem by doing one or more of the following:

   Send the message again, but before you do, delete and retype the address. If your email program automatically suggests an address to use, don't select it.
   Clear the recipient AutoComplete cache in your email program by following the steps in this article: Status code 5.1.1. Then resend the message, but before you do, be sure to delete and retype the address.
   Contact the recipient by some other means (by phone, for example) to confirm you're using the right address. Ask them if they've set up an email forwarding rule that could be forwarding your message to an incorrect address.

The sender of the email gets those message. I get them also but I'm also getting the message that they send me. It's only doing it with my outlook account. Why is that? I checked it directly on the Outlook website and everything is OK. I can't understand why this is happening.

None of my saved passwords in my Mozilla account are showing up when I switch laptops and try to logon to various sites. Instead I have to manually enter the passwords for the sites every time even though the sites show that I have saved passwords for that site in my Mozilla account. When I type the password in a old or new site, Mozilla doesn't even ask if I want to save the password anymore.

Before you answer with a cache and cookies response, they have been cleared. Performance on Firefox has been getting worse and worse. Not sure what the end game is to make a once great browser into a dinosaur but mission accomplished. Frames on some sites are pushed all the way over to the side so they are, either difficult, or impossible to read or access. After a shutdown, the amount of time that it takes for a browser window to stop loading is about 12 minutes. This is absurd. I just tried loading some reels this morning and all it does is spin, waiting for the download. I left one up for 30 minutes and it just keeps spinning. I did cut and paste into Chrome, and Opera and they opened immediately. What is going on?

Hello I've been a Firefox user for decades; recently a problem suddenly appeared that I'd never encountered before; I mentioned it to you but you didn't see fit to reply. I have twice 'repaired' Firefox, to no avail. After hours of Internet research, I've discovered the nature of the problem: it's called FirefoxCP Isolated Web Content. According to the many forums I've consulted, you're perfectly aware of it. So I don't understand : - why you don't take the trouble to reply to a user with a problem. - and, above all, that you're perfectly aware of the problem and don't do everything in your power to solve it. As 'killing' an activity in my Mac's activity monitor every ten minutes is rapidly becoming unbearable, I'm going to have to change my browser, much to my chagrin. Farewell dear Firefox!
