The latest update for the beta version 153.0b1 of 6/16/26 has made my theme stop working although it still says enabled. The theme is: ANIMATED Sakura by candelora 🌸 Theme Designed by candelora © 🌸 Animated Apng Theme I'm using Windows 11 on a Lenovo IdeaPad Flex with Firefox as my default browser. I'm an old lady, not tech-enabled in any way. Please help and thanks.

I installed Firefox Developer Edition and I am having the following issues, whenever I go to Indeed and I go to a job posting the browser opens up additional tabs without my permission or me doing so. Also the browser does the same in Canvas when I go to my course the browser automatically opens up new tabs without my permission and also me doing so. The Firefox Developer Edition browser update is Firefox Developer Edition is up to date 152.0b7 (64 bit). The following extensions are installed AdBlocker Ultimate, FoxyProxy Basic, Ghostery AdBlocker For Privacy, Malwarebytes Browser Guard, Privacy Badger, and UBlock Origin. This behavior got super annoying and I don't know how to fix it. Any help on how to fix this would be appreciated. My operating system is Windows 11.

I'm a beta update channel user, so this may not reflect what 'normal' users are seeing. I use Firefox in Linux, debian v13, so normal people that are using Windows or MacOS also might not see the changes I'm asking about? -- I have no way of knowing.

Anyway: in FF v152.0b6, the "Connection Settings" area seems to have disappeared entirely from the settings menu. I used this area of the settings frequently.

The ability to set proxy still exists in the about:config settings area. In the future, will about:config be the standard place to go for people that want to manually set (or toggle) an http/https proxy?

Thanks for reading, and thanks to all the Volunteers who make this place and Mozilla software function. I use your stuff all day, every day, and my life is better because of it.

Hi whenever I use my Google account to sign into websites (Google, ebay, YouTube, & anyother sites,) Firefox will become unresponsive, the window containing the tab i was using becomes unresponsive, sort of. - I can't click any open Firefox Tabs, - the red 'Close' radio button is greyed-out, so I can't close any tabs or the window - right-click is unresponsive, so i can't close tabs that way, but Command-W closes the tabs normally, but the others are still unresponsive.

- i can open a new Firefox window (with &/or without Tabs,) which works normally.

- & unrelated, but earlier, Firefox was running really slowly, Youtube videos were slowed down, but audio was normal, and scrolling was slow.

I have a ASUS Vivobook S15 with snapdragon cpu

Some homepages would not come thru it is the same as i can connect to from my win10 computer without problems If you see bad spelling, i have tried to add on English langugare, bur it does nor work

Win11 , Firefox 152 allways updated

All my Tabs Group have disappeared from the Tab Bar. I can see the Closed Tab Groups in the drop down but i can't find a way to re-open Closed Tab Groups. Any clues welcome. Running 146.0 and on the beta update channel.

Сегодня 23.04.2026, я открываю браузер и вижу, что моя строка и ярлыки находятся сверху, а не в центре(1 скриншот). Вчера 22.04.2026 все было хорошо, я покажу на 2 скрине как это должно выглядеть. Хочу заметить что у меня включена функция Handoff и она мне удобна, но мне неприятно видеть блок с ярлыками и строкой не по центру. Я использую тему ffultima, скажу еще раз, вчера все было нормально. Версия фаерфаокса у меня - firefox developer edition

So, forgive me, I'm a little frustrated right now, but I needed to move an Open Tab to it's own window, without the use of my mouse (yes, it's having issues right now), but: I used to do this by tabbing to the TAB in question and pressing <Shift> F10, which opened a context menu with a Move To sub-menu. Now the menu didn't have that option. see pic below. ...Yes, I was able to do the same via, File | New Window, and coping the address to it with Windows cut/paste and <Alt><Tab>. Still I would like to know how to get to the TAB context menu option without the mouse.

Moderator note: this question has been edited to correct the formatting.

A couple of days ago I noticed that Firefox had started using "Profiles". I do not want a profile. When I wanted to open firefox a window popped up asking me to pick a profile. I deleted my account. Now Firefox will not let me use it because I don't have a "Profile". If I cannot use firefox without a profile, which I never had to do for umpteen years, then I well switch to Chrome.

gmail no longer works in firefox. Nightly has been giving me a message about clearing cache and cookies for many many many months. After I do that, nothing changes and I still end up in a website about clearing cache and cookies.

Firefox ESR is not able to delete gmail emails after I check the delete box. It says they are deleted but the don't ever go away.

I cannot find any version of firefox that works with gmail. Please let me know if you have found one and provide a link for me to download that version.

thanks

Hello. Why nexusmods.com and loverslab.com are blocked (Secure Connection Failed) on my FireFox Dev Edition 150.0b6 (auto updates)? It bothers me to use it as a default browser. Both nexusmods.com and loverslab.com are ping well and work fine on any other browsers.

I have a directory structure

C:

   Gustafson
       Website
           ⋮
           scripts
               global.js
               ⋮
           ⋮
           TestDirectory
               baseUrl_test.html
           ⋮

In the <head> of a webpage, I determine a baseUrl for the page using the following:

 <script>
   // assumes website topmost directory is "Website""
   ( async ( ) => {
     const segments = document.documentURI.split ( "/");
     const index = segments.findIndex ( element => 
                                        element == "Website" );
     if ( index < 0 )
       {
       throw new TypeError ( 
                 "Website structure not constructed correctly" );
       }
     segments.length = index + 1;
     let path = segments.join ( "/" );
     path += "/";
     window.baseUrl = path;
     console.log(`${baseUrl}`);
     } ) ( );
 </script>

The console log displays

file:///C:/Gustafson/Website/

In the body is

 <script>
   console.log ( `${baseUrl}scripts/global.js` );
 </script>
 <script src=`${baseUrl}scripts/global.js`></script>
 <script>
 window.onload = 
   function ( )
     {
     Global.initialize_globals ( );
     };
 </script>

The console log displays

file:///C:/Gustafson/Website/scripts/global.js Loading failed for the <script> with source “file:///C:/Gustafson/Website/TestDirectory/%60$%7BbaseUrl%7Dscripts/global.js%60”. Uncaught ReferenceError: Global is not defined

   onload file:///C:/Gustafson/Website/TestDirectory/baseUrl_test.html:37
   EventHandlerNonNull* file:///C:/Gustafson/Website/TestDirectory/baseUrl_test.html:34

The problem is the console.log displays what is expected but the src= is using something totally different.

I have vertical tabs enabled and the "expand when hovering mouse" option is activated (see screenshot). However, the latter functionality tends to glitch at some point in basically every session. I can't tell if a specific action triggers it, so far it seems pretty random. The glitch is that either the tabs are expanded and won't collapse, or the opposite: they're collapsed and refuse to expand when I point at them. Is this feature maybe still experimental? or something? I'm running Firefox 149.0b5 DEveloper Edition on Garuda Linux (Arch based).

Hello: FF dev 150b5,w11p. With this v 150 there's a new irritant that I would like to stop, please. That's the sudden (starting w/v150 again) appearance on lower L corner, of a popup window, which may be interactive. That is, this thing is so new I can't say more about it except that I didn't change anything to make this thing appear, & this didn't happen in prev.versions.

I looked in settings & the only thing on keyword "popup" goes to, in "search results", is: "block popups & 3rd party redirects." I already had that choice checked from previous versions (that is, do block). But this new popup appeared (unasked) anyway.

Is there an extension that will stop these? If so, what keyword(s) do I put into the "search extensions" box to find the extension(s)?

Also, w/this new "wonder" of unasked-for popups -- is this another "coming w/AI" feature I will have to live with?

I did a search here on "popups" before posting,but came up w/nothing relevant.

Thank you.
