Diễn đàn hỗ trợ Firefox

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.

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

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

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.

I am currently on windows 11 for ARM (surface laptop 7) and this problem is occurring with both Firefox as well as Firefox developer edition. It's also only happening on my external monitor. I have done some searching and found posts from as long as 4 years ago. The posted solution is to disable any compatibility options but in my case none are selected. This is driving me nuts, does anyone know of a solution? This has to be firefox specific because no other program does this, including other browsers. I have included a screenshot to show what it looks like.

It's a bit weird, I got the thing you get when you migrate to a new browser - asking if you'd like to migrate history and bookmarks. I closed it because I've used Firefox for years.

When Firefox opened proper, I got a tab asking to restore the previous session, along with a "Welcome to Firefox" tab. As well I got a few popups for other things, basically just stuff you see when you open Firefox for the first time. A couple of extensions opened up a landing page that should only open when you first install them.

All my bookmarks and browser history is there. The settings have all been reset to default. The extensions are there but all of their storage seems to be gone, like my dark reader extension no longer has the exception sites on it. Ublock has the ad count reset and most importantly all my custom rules are gone! I have spent years making hundreds of custom rules, and quite a few took hours to get right. I am sad about losing that.

Does anyone know what might have happened?

When I was looking at my about:config to see I saw these things in the modified settings.

there's quite a few settings here and IDK which are relevant. The ones in the pictures where just the first couple and I show them because they seem to have something to do with this situation "auto migrated" - when it seems like the browser did this because it thinks it migrated, the first screen I got was asking if I'd like to transfer my bookmarks and history (and good thing I closed it,or it might have deleted those too).

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.

starting the computer I receive following message: C:ß\users\....\AppData\Roaming\Mozilla\Firefox\Profiles\ibp4oc3n.default-release\search\json.mozlz4

can notbe opened

whatshall I do?

Thank you! Anne

Hi everyone, I've been experiencing a persistent issue where my Firefox (Windows 10) randomly crashes or closes. I recently noticed that this always happens when a JSON file appears in the following directory: C:\Program Files\Mozilla Firefox\distribution The strange thing is that this file shouldn't even be there, as this is my personal computer and it is not managed by any organization. I have already tried deleting or renaming the file, but after a seemingly random period, it gets recreated automatically. Here’s what I have tried so far, without success: - Deleting/renaming the file - Checking the registry at HKEY_LOCAL_MACHINE\Software\Policies\Mozilla\Firefox (but the "Mozilla" folder does not exist there) - I have never used any third-party antivirus software (only Windows Defender) Does anyone have an idea where this file might be coming from or how I can prevent it from being recreated? I’m not very tech-savvy, so I would greatly appreciate simple explanations or step-by-step instructions. Thanks in advance for any help!

FIREFOX SETS LILBOBAGS1 PROFILE PAGE AS MY ROBLOX SHORTCUT ON THE NEW TAB, AND ROBLOX RUNS SOOOOO SLOW!

FIREFOX IS [edited] MAKE IT 100000% FASTER OR IM SWITCHING TO CHROME!

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.

Hello, I am a tinkerer and I would like to tweak my Firefox Developer Edition to suit my tastes, but I don't know what each of the preference commands does. Could you provide a list explaining what each command does and, if possible, how to use them? I don't want to reinstall Firefox.italic text I prefer to do things properly. Thanks

Previously, I made a custom scale ".3,.5,.6,.7, .71, .72, .73, .74, .75, .76, .77,.78,.79, .8,.9,1," and thus using Ctrl + the mouse wheel allowed you to set any scale in this way, since when "Ctrl + mouse wheel" the page was scaled by 10% regardless of the values. That is, I could set 74% and use Ctrl + mouse wheel to make the page scale 64% or 84%, even without the available value. Now I can't do this because now my "Ctrl + mouse wheel" doesn't increase/decrease 10%, but just scrolls through the set values. How to get everything back? It's very annoying, I can't use it.

Hello,

I hope you are doing well.

I am contacting you regarding my Firefox account, which is currently registered with my ProtonMail email address that I no longer have access to.

Unfortunately, my ProtonMail account has been permanently disabled, and I am unable to receive any verification emails.

I would like to request your assistance in updating my account email address to a new one.

I can confirm that I am the rightful owner of the account and I am willing to provide any information necessary to verify my identity, such as:

Previous account details Login activity Devices used Any additional verification you may require

Additionally, I am currently located in Iran, where due to recent internet restrictions and instability, I have had to rely on VPN services, which may have contributed to unusual activity patterns.

I would really appreciate any help or alternative verification process you can provide in this situation.

New email address: intelligentquantum@gmail.com

Thank you for your time and support.

Best regards, Hamed

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.
