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.

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

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!

Hey there,

Whenever I use the picture in picture feature on Firefox to watch something while doing other things,it has randomly gained these black bars on the side of the image and I can't work out what is different? If this is a quick fix, I haven't been able to find it, sorry!

Thank you in advance!

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?

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.

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.

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!

I know that after PiP(Pitcure-in-Picture) is enabled, I can use it in two ways: one is the button on the right side of the address bar, and the other is the icon button floating on the video. I'm trying to figure out how to keep the PiP button on the address bar while hiding the icon button on the video. I do not want to turn off PiP, I just want to hide the icon button on the video. I tried setting it in about:config, but it only seems to have the opposite effect. If it's not possible to achieve what I want, where can I request this feature from Firefox?

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 am having issues disabling picture-in-picture mode, even though I have disabled it in my settings.

The settings regarding picture-in-picture mode (in general) and the Firefox Labs' "Picture-in-Picture: auto-open on tab switch" do not seem to work. I am disabled and re-enabled these settings multiple times, though picture-in-picture mode still auto-opens on tab switch. I have restarted my computer and Firefox multiple times.

Please advise on potential solutions. Thank you!

Since a recent version of Firefox was installed the picture in picture control does not work. I have unchecked the option but It still shows in YouTube etc.

I know this can be disabled in about:config but I prefer not going there. I wonder if this will be corrected sometime, otherwise the setting option is pointless.

Another item: I have unchecked the search suggestions in settings but it makes no difference.

Input welcome.

For some reason my install of FireFox on Linux refuses to hide the picture-in-picture button in the address bar on video sites.

See included images; all relevant settings are disabled.
