Hello Firefox Support Team,

I would like to report a browser compatibility issue regarding CSS positioning behavior that differs from Chromium-based browsers.

• • Issue Description:**

When an element with `position: sticky` is placed inside a container with `position: fixed`, Firefox treats the sticky element as if it has `position: relative`, effectively breaking the sticky positioning functionality.

• • Expected Behavior:**

The sticky element should maintain its sticky positioning behavior even when nested inside a fixed-positioned container, as it does in Chromium-based browsers.

• • Current Firefox Behavior:**

The sticky element loses its sticky properties and behaves like a relatively positioned element.

• • Use Case:**

This issue particularly affects modal implementations where: - The `body` element receives `position: fixed` to prevent background scrolling - Page elements (such as `.total-section`) should maintain their sticky behavior regardless of changes to the body positioning

• • Browser Comparison:**

- **Chromium browsers (Chrome):** Sticky positioning works correctly in this scenario - **Firefox:** Sticky positioning fails and falls back to relative behavior

• • Request:**

Could you please consider aligning Firefox's behavior with other major browsers? The current inconsistency creates cross-browser compatibility issues and forces developers to implement JavaScript workarounds.

Thanks!

There used to be a much more useful interface for clearing specific browsing data (the landscape-oriented one). The new interface is far less detailed to the point of strictly limiting its functionality. There used to be a config setting ("privacy.sanitize.useOldClearHistoryDialog") that could toggle which interface to use, but as of an update in the last week (I've been away without a computer for a while), that toggle does nothing. Is there any other setting that can make this feature actually useful again?

Firefox has "Open previous windows and tabs" ticked in Settings. I had to force restart MacOS, and upon starting Firefox again my existing windows are invisible. They are shown in the Window menu and when right-clicking the Firefox icon in the MacOS dock, however when I select one of the windows it does not become visible. Command+` does not show the windows either.

I can however open new windows.

I tried renaming xulstore.json per this old article with no effect.

How can I make the existing windows visible again?

I am having difficulty using Google Sheets within Firefox Developer Edition 144.0b4 (64-bit) on Linux Mint 22.2 Cinnamon. When I load any of my Google Sheets, I am unable to scroll. This includes when using a blank sheet.

I also have Firefox 143.0.1, which seems to still be functioning correctly.

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

I don't need to pin tabs, ever. Every time I try and drag a tab to the first slot, it always pins the tab, and I don't want it to do that. Is there a way to disable this stupid feature?

Hello,

I have three devices: a desktop and a laptop with Windows 10, and another laptop with Ubuntu (LINUX).

I read that I can purchase a VPN installation. Do I need to buy three separate VPN installations or one with a single login and password?

Thanks, Pavel

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: 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.

/edit:fixed a formatting issue causing horizontal scrolling

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).

Win 11 Pro, Firefox Browser-Developer, 147.0b9, 64bit Problem recently occurred. Example it was working fine this morning and after turning the computer off and restarting later in the day this happens. The image below shows faded access to the password manager. Link that appear do not work: Log in at the header and link in password support highlight in the visible text portion. Thanks in advance for your help

the msg returned

Hmm. We’re having trouble finding that site.

We can’t connect to the server at marvelsearch.com.

If you entered the right address, you can:

   Try again later
   Check your network connection
   Check that Firefox Developer Edition has permission to access the web (you might be connected but behind a firewall)

i am using a local dnsserver and firefox is connected to it. is this the reason? if so how can i disable this? other firefox features are working beautifully.

Hi,

The 'Forgot password' option is not working in Firefox. I tried it multiple times and it doesn't send me a temp password/recovery link to my email. It just says 'Invalid account'. Please take a look.

Thanks
