Firefox Community Forum

I asked this a year ago and never saw a solution (other than 'gee, it should work yet'.) I use the local Windows Hosts file to give my router a quick reference name to get into it. That too has worked for years but began to fail last year. Inconvenient. The best I could track this down, it has something to do with forced DNS lookups and skipping the old Hosts file. If so, any work around to get my system simplicity back? Attached is what I see on each attempt.

I tried various settings for DOH and nothing works. I can reference the Hosts file in a Windows Cmd Prompt and it resolves just fine. Something is screwy in Firefox for some time now and I'd like to know what.

I have searched these forums for "always on top" and the results were completely useless, so I assume no one has asked this question before, or the search engine is ineffective.. anyway, the question is:

When watching a video where you can click the right-side button to pop the video out to Picture-in-Picture mode, the video window that pops out is permanently set to Always On Top. It is often inconvenient for it to be Always On Top. I would like to be able to right-click on that video window and be able to select an option to disable Always On Top, or failing that, I would like to be able to disable this Always On Top via manually setting something in about:config. Can anyone recommend a solution that doesn't involve installing any third-party software to control Always on Top behavior? Thank you in advance.

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

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!

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!

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.

Firefox Picture-in-Picture (PiP) Issue

• Problem: PiP window loses "Always on Top" focus or vanishes when switching workspaces/tasks.
• Config Changes: Set 'focusmanager.testmode' to true and 'media.videocontrols.picture-in-picture.video-flips-visibility-on-focus-change' to false.
• Window Settings: Focus set to "Click" via GNOME Tweaks/Settings.
• Environment Test: Tested launching via 'MOZ_ENABLE_WAYLAND=0' to bypass Wayland focus logic.

Software & Tools

• Tweaks: Installed for font hinting (Slight) and window behavior management.

The picture-in-picture setting use to keep the detached video visible if I scrolled the original or source page past the video player. Now the detached video disappears and reverts back to the source page when I scroll this control out of view. Is this change intentional and permanent?

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

Good afternon,

I am writing to request assistance in disabling the Picture-in-Picture (PiP) feature on my browser. Despite my best efforts over the past few days to disable this option through the settings, it continues to activate when I listen to music on YouTube.

Each time I navigate away from the YouTube tab, the Picture-in-Picture window appears and persists across all my other tabs, which is quite distracting and impedes my ability to work.

Closing the PiP window pauses the music, which is not ideal for my experience.

I am looking for guidance on how to effectively deactivate this feature, as the settings adjustments I have made do not seem to take effect.

Any help you can provide to resolve this issue would be greatly appreciated.

Thank you for your attention to this matter.

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?

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 !!!
