Firefox Community Forum

Recently, whenever I put a video in PiP, the whole browser freezes. I'm not sure what causes it. The PiP player itself is playing and working fine, it's the browser as a whole that freezes completely. I can play/pause and even pop it back to its tab, but when I do, the browser is inaccessible to me because it freezes, despite the video still playing normally. I can only terminate the browser with Task Manager, otherwise the video will continue playing and the Firefox process goes on the background.

I have tried Googling for a way to fix it, but nothing seems to work. Some of the recommendations were to turn Hardware Acceleration off, allow autoplay, upgrade GPU drivers, and test in Troubleshoot Mode. I have autoplay completely off (including in about:config) and gave an exception to YouTube. I don't think this is the problem though, because I've had it set up this way for a long time, and the browser freezing only started happening recently. I have had Hardware Acceleration off for a while too, so it's not because of that. My GPU drivers are up-to-date (Nvidia). The browser still freezes in Troubleshoot Mode.

The problem is not limited to YouTube. Wherever I can pop the player off with PiP, it will freeze the whole browser (like Twitch or any other site with video player capabilities). I tried playing a video in a different browser and it worked just fine with no freezing, it only happens in Firefox.

I noticed that the common issue people report is the PiP player itself freezing, but my case is the exact opposite. The PiP plays fine while the rest of the browser freezes. I really like this feature and don't want to turn it off if possible. I like to pop the video out and watch it play while I scroll around on my desktop.

Running Firefox 140.8.0esr (64-bit) on Windows 10 Pro on an HP laptop. The feature/problem described works properly with Chrome and Edge. The problem occurs when accessing the following article:

If the window is set wide enough, there is a sidebar displaying, "Share this content in X". If the screen is squeezed down (i.e. drag the right margin to the left) far enough, the sidebar will disappear. That feature is handled properly, but as the window width is increased and the sidebar appears, the main body of text does not wrap properly. It appears that Firefox is not compensating for the width of the sidebar.

 NOTE: As I am not a HTML expert, my subject line referencing a particular HTML class could be misleading.

Watching a CNN video on YouTube Firefox suddenly freezes and does not accept any further actions. Even shutting down it will block the process and I need to use the "Shut down anyway" function. Similarly, Thunderbird will lock up in the middle of writing a response, but here it is just the window and I lose what I typed, but I can go back and push "reply" again and retype the answer. Whether these are down to similar issues I don't know. Obviously, this sounds like a graphics driver, so I made sure all updates are installed and there is no further update available for both, Firefox and Thunderbird as well as the system drivers.

Any pointer is appreciated as this is really annoying. Thanks

Why can't Firefox open .mht email extensions within its default browser? It has never done so to my knowledge. They always point to Internet Explorer or Microsoft Edge.

Often an email may not display images correctly and the ability to open them in a web browser is offered, "If there are problems with how this message is displayed, click here to view it in a web browser." This is certainly a development addition when people view their Gmail from Firefox or use Outlook. Not everybody uses APPS. People who don't want Microsoft Edge watching every move they make have made effective permanent changes in removing the deep embedded PUP by Microsoft.

Firefox version: 148.0

I'm trying to stream a show in the firefox browser and I am getting error saying the HLS is not up to date. I've checked my firefox is at the latest update, is this something you need to update on your end?

Not sure but I read that windows 10 has reached the end of support in oct. 2025. I have no idea what book marks I had because My friend put them in for me. I do not know why firefox or windows had the rights to chage my computer and I do not have the funds to buy a new windows 11 computer. So bottom line what can I do to fix this issue

I have been with Firefox since Netscape Navigator so I understand how it works. I have a Bulletin Board Forum (work on it daily). Posting to the forum using long form bbcode is very time consuming and tedious.

I've been using bbCode for Web Extensions (bbCodeWebEx) (https://addons.mozilla.org/en-US/firefox/addon/bbcodewebex/) for years and up until the recent Firefox update it has worked perfectly.

Matthew G. Saroff (https://addons.mozilla.org/en-US/firefox/user/96273/) was the developer of the extension.

I have tried using the extension on multiple sites. The extension is there and functional but nothing registers in the edit windows. not even here.... I've looked for replacement extensions but none have the specific abilities I need for posting on my forum. Specifically- The ability to select an img coded image address and make it link to a specific webpage url. Other common bbcode can be tagged using the edit window's fully enabled wysiwyg editor.

I'm not sure if other extensions are having issues with this release but the rest of my extensions function normally. Something changed which blocks the paste functionality of the coded clipboard text into the edit window. I might be a developer issue but my question to him is, as so far, unanswered.

I tried to install an older version of Firefox, Downloaded the install, created a new profile, uninstalled this version and it worked until I restarted Firefox (with updates set to manual). It automatically updated and I lost it again. I tried using ~about:profiles~ to revert but it reverted as that profile this version. Years ago, I used Waterfox so I could use the Legacy extensions. I stopped using it when I got accustomed to the new extensions. For the past few years, Firefox is the only browser I use. I don't want to have to cut my teeth on a new browser but as the administrator for my forum, I use bbcode everyday.

I am wondering if any other Firefox users are having issues with the recent update? Thank you for reading my concerns.

Many websites that I use regularly, such as Zillow, no longer work correctly in Firefox ESR (115.33.0). The top menu in Zillow disappeared this week. Others work, but all the text is greyed-out. All except the text thing seem related to Javascript features. For instance, check boxes on a Wordpress site that I manage quit working last month. Some, like www.RCgroups.com just sit and spin, and never fully open up.

But they all work fine on an old copy of Chrome (109.0.5414.120), that is no longer supported on Windows 7 and hasn't been updated in probably 3 years.

My only plugin is NoScript, but the problem is the same whether it's turned off or not. And I also use NoScript on Chrome.

I use Win7 for the same reason I use Firefox -- it is safer, far more stable, faster, and it doesn't force updates on me that invariably break things. I appreciate that Mozilla has extended support for the last stable version of Windows. But somebody should look into this growing compatibility issue.

How do I completely uninstalled Firefox and revert back to the previous version, and turn off auto updates?

I can access my credit union using firefox on my phone, or even this computer when using MSN. I can NOT reach my credit union on this computer using firefox. I get a 403 forbidden message.

When I start MF, all tabs I have used before open. Good! But one of these tabs are not in use. That it why I want to close it for ever.

The option to delete it for ever is not available.

Grateful for your help!

Could someone please help me retrieve my crash report history? My Firefox crashes more than 10 times a day. When I check **about:crashes**, it doesn’t show any reports right now, although I saw some there a few days ago. Is there any way to recover those reports so I can submit them here for further guidance from experts?
