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.

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!

When using version 143 on linux and PIP is open and I go to another workspace the PIP does not show on any other workspace other than the workspace it is already on. This does nt occur with Chromium browsers as there PIP follows on any workspace.

What should happen is the PIP in firefo should always appear on the displayed screen I am working on.

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

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!

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.

while watching YouTube in direct mode ... F revert back to normal mode every time new advertisement cut into the flow I have to reselect picture-in-picture mode. Will work reliably till new advertisement

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?

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?

When I close a tab that had a video playing, the picture-in-picture box will stay there after I close the tab. The picture is just a white box. The controls are there, but when I click on any button, nothing happens. I can only move the box around and resize it. It usually happens when I close the tab while the video is playing, but sometimes it happens when I close the tab and the video is paused. It happens on videos that were in a picture-in-picture box and videos that weren't. I go into setting and disable picture-in-picture which will stop new picture-in-picture boxes, but won't get rid of the white box. The only way to get rid of the white box is to close FireFox completely and then reopen it.
