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

Many web pages that have a video header will launch the video in a popup window after you scroll past the header.

There are no user controls in the popup window, and clicking 'block popups' and turning off 'enable p-n-p controls' had no effect on them.

Is there a a setting that will stop these video popups from automatically launching? They eat up a lot of memory, and are a pain to turn off manually.

Thanks.

Hi all,

Just updated to version 142.0.1. I now have the annoying behaviour back that video's on a website pop out on the screen while scrolling on a webpage and they are in the way of the text. I don't want any videos popping out. In the past I had it resolved somehow, so it looks like the update "undid" these. If I'm correct I might have changed a setting in the about:config.

I found multiple articles stating to uncheck "Enable PIP controls" in the setings, section [General] - [Browsing]. This options was moved to the [Firefox Labs] section within the setting. This option however is already disabled.

This page does not resolve the issue: https://support.mozilla.org/en-US/kb/about-picture-picture-firefox#w_why-dont-i-see-the-picture-in-picture-toggle

How can I prevent a video popping out on the screen an float above the web page? I just want to keep it in the window\frame where it belongs.

Link of a page where I have the issue: https://www.telegraaf.nl/video/oprichter-sbs-hiermee-onderscheidt-sbs-zich/86683036.html Also attached a screenshot.

Thanks in advance.

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?

I am experiencing an issue with the Picture-in-Picture (PiP) functionality in Firefox on Ubuntu. Unlike on Windows, where the PiP window automatically appears when switching tabs or pages, this does not happen on my system.

When I manually activate the PiP feature by clicking the button, the window does appear; however, it is placed behind the browser window and remains at the lowest level among other open windows. This causes it to be obscured by other applications and requires me to manually bring it to the front and adjust its position every time.

Is there a way to automate this process or resolve the issue so that the PiP window behaves as expected (i.e., stays on top of other windows and works seamlessly)? Please let me know if there are any settings, extensions, or workarounds that could address this problem.

Thank you in advance for your assistance!

How can I stop sticky/floating videos in firefox? I've tried every solution possible googling and nothing works. When I browse a page with a video that I don't care about watching (I'm reading the page) a smaller version of the same video pops up on the lower right side of the page and continues to follow me down the page regardless of how many time I click on the "X" to make it disappear, it simply pops back up again once I start to scroll further down the page. This is so annoying !!!

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.

Recently, I've been noticing an issue with Firefox's built in Picture-in-Picture (PiP) feature. When watching media, such as a YouTube video, using PiP, the video runs as normal, but recently, the PiP completely breaks when I tab away from my Firefox window to do something in a different app. This wasn't the case a few months ago, so I'm not sure what changed to make this error happen. I had attempted to disable hardware acceleration to see if that was the issue, and nothing changes when it's enabled versus when it's disabled.

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.

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

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.

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?

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?

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!

Over the last 6 months, and increasing number of websites don't open on Firefox. I've noticed it most consistently on any of the wikipedia/wikimedia pages, but it's not just those. When I type in an address and press return, or click on a link, the browser just acts as if nothing has happened. There does not show me the loading symbole. If I ask it to open a new tab with the site, the address appears on the tab, but the page itself is just black. Other browsers have no problem loading the same sites. I am on a mac, and using a VPN. Restarting the browser doesn't help, though restarting the computer sometimes does.

Thank you,

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.

Using hyprland, in one specific firefox profile, whenever I toggle PIP and resize it to be smaller than its original size or toggle float on the window, it just closes. Trying it in a different firefox profile, none of these issues are present.
