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?

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.

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!

Hello all! Recently I have run into a problem when using the zen browser on my Fedora laptop that I have been unable to resolve despite my best efforts ... specifically, when I double-click on a web-site I have bookmarked and stored under "Bookmarks Menu" it does not come up unless I manually select a container to open it in. I am using Firefox sync so as to keep zen and firefox in sync in both my laptop and desktop and firefox on my Driod. I have reinstalled zen from scratch, I have signed out fo sync and tested, I have disabled my "Facebook Container" extention, and I have attempted to set a default container for the workspace I am in, but nothing seems to change the problem I am seeing.

Do you have any suggestions as to how I can simply click on on bookmarks and see the website without any further clicks [like I used to do up until recently]? Is there any additional info I can give you? Thanks for your time!!! - John C

With update 136.0, FF is requiring us to use a master password. I have one already set so my data is protected. I do not need a master password to open FF, but now I do.

STOP THIS MADNESS

Hello,

Two things:

1. When I open a link in Firefox, the back button will not work taking me back to the page before.

2. I want to be able to open another page with another page open.

Any advice or suggestions appreciated,

Don

Firefox will not longer close without also closing my pinned tabs which pretty much defeats the purpose of pinning tabs for later and makes it much harder to keep track of things. I didn't notice the first time and lost my pinned tabs that had been there for months, I immediately put them back but now everytime I try exiting firefox it informs me i'm about to close however many tabs are open + the pinned tabs. Does anyone know how to solve the problem/what might be causing it.

Every time I try to view a pdf file on Firefox I can view the file but in the lower right 1/4 of the screen I get a graphic of a page with shaded areas representing lines with writing on them. There is a type of pen cursor moving along the line.

This happens with different pdfs - from the internet and from my saved files. This doesn't happen on another computer with Firefox.

I've deleted and redownloaded Firefox an number of times, also tried troubleshoot mode - no improvement. Virus scanned, restarted a number of times.

Pdfs work on edge and chrome and reader with no problem.

I have a screenshot.

Any Ideas? Thanks

Can you guys check why your netflix account is getting logged out every time regardless of how many times you logged in and for prime video if you play any video i'm getting video player error, can you please check

I am sorry if this is not the place to ask this question. I am new to web development and have been trying to solve this issue for days. I have an ESP32 acting as an http server. I have developed web pages which have separate html, css, and javascript files. These work as expected when delivered locally (i.e. I double click on the the files), however, when they are served by the ESP the style sheet is ignored and I get the message

The stylesheet (url) was not loaded because its MIME type, “text/html”, is not “text/css”.

from Firefox debugger. The stylesheet is ignore across all browsers (Firefox, Chrome, Opera, Edge), however the error is only shown in Firefox. Normally, of course, I would expect an issue on the ESP32 side, however, the non-Firefox browsers do load the stylesheet (even tough they ignore it) and I am able to verify that the stylesheet is identical to the one served locally.

Oddly, if I open a Firefox tab and load the page, switching to developer mode causes several requests for the stylesheet and the styles are then applied. Subsequent refreshes of the page causes the style to be lost and closing/opening developer mode has no effect.

Although I have disabled javascript to try fix this problem, when javascript is loaded I get a similar message (except the javascript is loaded).

I believe I specified the MIME type because I exactly coped several examples

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="utf-8"/> 
    <meta name="viewport" content="width=device-width, initial-scale=1"/>
    <link rel="stylesheet" type="text/css" href="styles.css" />
<!--<link rel="stylesheet" type="text/css" href="name-of-stylesheet.css" />    -->
<!--    <script type="text/javascript" src="ESP-UI.js"></script> -->
    <title>My ESP32</title>
</head>

Thanks for the help!

This question relates to version 134.0.2 (64-bit). This morning I started Firefox and found that many of my bookmarks were missing. On trying to restore from the program automatic backups, I get the repeated message "Unable to process the backup file." On examination, the files, while not in ASCII, appear to contain ASCII text strings recognizable from the bookmark descriptions. They are not, at least, empty. Unfortunately, I do not have an HTML format backup. Any idea why none of the backups work or what options I have? Thanks in advance.

Starting early this morning I could not open a website (where I purchase supplements) I have accessed in the recent past. I added the address to the DNS listing but that didn't help. In the verification lock icon in front of the address it says the connection is secure. But below it states the Connection verified by a certificate issuer that is not recognized by Mozilla. Prior to 1/22/25, I had no issues opening this or other websites. It doesn't matter if I have my VPN turned off or not, the website does not open. Was the Mozilla update of 1/22 the cause? If so, how do I rectify the issue I currently have? If not, how do I rectify the issue I have?

When using the PiP feature is there a way to switch whether it pauses the video when closing the PiP player?

Often if i want the audio to continue but dont want the popout player there and if I press the close button it will just stop the audio. If I select the PiP window and use the shortcut CTRL + SHIFT + ] the audio will continue playing as I want it however this is inconvenient and requires using the keyboard, is there any way to change it so that closing the popout player doesn't stop the tab from playing audio?

i have Linux Cinnamon 22 and want to stop the PIP on YT. I disabled/unchecked box for PIP on FFox and PIP still happen on YT. What can i do to stop this horrible PIP now ? thank you.
