Firefox Community Forum

I have had the YouTube Nonstop extension for a few months. It was great. It let me play playlists without stopping every few songs. Then today it quit working.

I turned it off and back on but that didn't work. I looked for an update but the last one was 2 years ago.

I haven't tried removing it and reinstalling it. I guess I will do that. Anyone have any ideas?

I see people communicating with the developer on the App store, but I can't find out how to do that. I don't see a link to the developer.

Any help would be appreciated.

I found some information about deleting closed tabs from Firefox.

Please allow users to select a date or date range instead of a maximum number of tabs and windows. Computers often restart, for instance when installing updates, and some sessions will include more tabs than others.

Thanks in advance!

I'm using a Windows/Linux client called WSL (Windows Subsystem for Linux). I've installed Debian as my WSL OS and for a long time I had Debian version 10. Firefox worked fine with ver 10 but this morning I upgraded to Debian version 13 (which required me to upgrade to the latest version of Firefox).

Firefox still launches okay but I wanted to change my home page to Google. So I clicked the 3 lines at the top RHS which showed me a popup menu but none of the options was selectable. Eventually I twigged that to change settings I needed to launch Firefox using sudo.

I managed to change the home page okay but I then realised that if I launch Firefox without using sudo, my new home page is ignored. Conversely (if I launch using sudo again) Firefox launches at a tiny size and can't be re-sized (at least, not using my mouse cursor). I've attached a small screenshot.

All I can do is to display it full screen and then I can tell that the home page is indeed now Google. I don't remember having these problems previously so can anyone give me a clue as to what I'm doing wrong??

Some how someone has attached to my computer and its system or programs, accounts Etc... Im not entirely sure, I am Looking for anything that I can Install or Add-On, Download or Extension's, Whatever Could Help Deep Search and Locate the Root Cause or Area where they were able to attach to my Files or whatever it is they latched onto.

I recently have been having issues w/ Firefox updates & data loss involving an extension I use / Clippings. For other reasons (gaming) I installed Brave browser to compare performance. As a result of the issues I've had recently I decided it would be a good idea to have a backup (export) of my passwords & decided to Import the .csv file created into the Brave browser. The last line of the .csv file has a line that begins w/

chrome://FirefoxAccounts

.... along w/ several other fields. The information contained implies that it has something to do with Sync & also references a URL:

https://identity.mozilla.com/apps/oldsync

... along w/ MANY other operands.

What does this line do  ? This does NOT appear to be a working 'setting command' option (like: about:logins or about:debugging) in either Firefox or Chrome. The first 3 cells look similar to (some information changed):

chrome://FirefoxAccounts a5847f4e7faf42f19f17c0f531c77acc {"version":1,"accountData":{"scopedKeys":{"https://identity.mozilla.com/apps/oldsync".... more

google blocking Firefox download. What do I do? When I open the downloaded browser app icon from Google store the browser changes to Google and Firefox is not in the drop down list either.

Information: I am using a custom theme, and rn im making some changes using about config mainly changing parfait.urlbar.results.compact parfait.window.borderless parfait.traffic-lights.enabled to true.

But my browser is unable to remember these and when i close and open it back up, it changes back to its old self where all of those are false. please help!

We have an asp.net Blazor SPA (server side Blazor) that dynamically generates components within the page. Over time, there is a very large RAM leak under document-shared that climbs until the windows are closed.

We have tried various firefox configurations to try and either disable this shared storage as well as limit but with no luck. THe memory allocation is in GB of RAM space and cannot be limited or reduced until the window itself is closed/restarted.

Research online indicates this can happen due to colocated stylesheets and how firefox wants to cache styles aggressively. Adjustments to move stylesheets does not appear to help.

What configurations can I use to help prevent/reduce this high RAM usage? This does not occur in Chrome or Edge, I cannot replicate this well under FireFox for Windows.

I have installed Firefox VPN, but it is disabled by default so I have to enable it whenever I use it . How can I change the default setting to make it on by default

My FF Browser introduced a vertical row of rings which I want to get rid off. Im using W10 and FF Version 151.0.4 (64-Bit). Rings are stable, updates show them again. Any Help???

Moderator note: Moved from the Firefox for Android forum to the Firefox Desktop forum.

I run the current version of Firefox (152.01) under Windows 11 Pro on a Dell Inspiron 15-3530 laptop. More and more frequently, I'm getting "Access Denied" messages when I click on a site link t56o an internal page. This happens on several sites, most notably Dell.com. I get the error in Troubleshooting Mode, and clearing the cache doesn't help. I've searched the information here, but all the responses seem to involve Windows 7 or Windows 8, not Windows 11. Can someone tell me how to resolve this situation in Windows 11?

Thank you.

After realizing what was being done to my PC, I unplugged it to stop the hacker. And I have since been able to recover my program, except for my ad blocker. Before this unusual encounter, I was using a free ad blocker. I want to restore it to its original status, if possible. Thank you for any help, Leman H Wilson at 7:09 PM 6-3-26
