I'm not sure what this feature is called in Firefox lingo...

On my Mac, Firefox will remember which windows belong on which virtual desktops, and so open up with them on the correct (well, not exactly, but sorta) virtual desktops after a restart of the app.

On my new Windows 10 installation, though, Firefox has learned that a specific window was moved to virtual desktop 2, and now INSISTS that that window should always open on the desktop after a restart, regardless of on which desktop that window was actually placed when Firefox was shut down.

Is there a quick fix for this issue, or at least some way to disable this feature?

Thanks :)

I am sorry if this is not the place to ask this question. I am new to web development and have been trying to solve this issue for days. I have an ESP32 acting as an http server. I have developed web pages which have separate html, css, and javascript files. These work as expected when delivered locally (i.e. I double click on the the files), however, when they are served by the ESP the style sheet is ignored and I get the message

The stylesheet (url) was not loaded because its MIME type, “text/html”, is not “text/css”.

from Firefox debugger. The stylesheet is ignore across all browsers (Firefox, Chrome, Opera, Edge), however the error is only shown in Firefox. Normally, of course, I would expect an issue on the ESP32 side, however, the non-Firefox browsers do load the stylesheet (even tough they ignore it) and I am able to verify that the stylesheet is identical to the one served locally.

Oddly, if I open a Firefox tab and load the page, switching to developer mode causes several requests for the stylesheet and the styles are then applied. Subsequent refreshes of the page causes the style to be lost and closing/opening developer mode has no effect.

Although I have disabled javascript to try fix this problem, when javascript is loaded I get a similar message (except the javascript is loaded).

I believe I specified the MIME type because I exactly coped several examples

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="utf-8"/> 
    <meta name="viewport" content="width=device-width, initial-scale=1"/>
    <link rel="stylesheet" type="text/css" href="styles.css" />
<!--<link rel="stylesheet" type="text/css" href="name-of-stylesheet.css" />    -->
<!--    <script type="text/javascript" src="ESP-UI.js"></script> -->
    <title>My ESP32</title>
</head>


Thanks for the help!

Why is the sessionstore.jsonlz4 generated from a private firefox window ? It is not private anymore if the session is stored in place of the regular session, which by the way happens not to be generated when the regular firefox window is closed while a private firefox window is still open. The private firefox window should have no effect on the regular session storage and should never be stored, all this is very confusing.

In daily work tasks, I end up with a large number of windows and tabs open. I am wondering if this is not adding to my extremely slow recovery of frozen tabs and windows and MANY instances of "Non-Responsive" everyday. Firefox is set to allow multiple processes, naturally, but I'm looking for ways to ease the pain here. If I disable Multiple Processes in Firefox v138.0.1, will I have problems running, for example, 5 windows with a total of 30 tabs spread across those Windows? (God knows I don't wanna have to grow up and actually manage the things I open up for stuff.) In addition, I am running Canva, sometimes Paint 3D, and Office 2021 concurrently. An associated question........in this most recent Firefox, how do I run Multiple processes, but limit the number of them to 5, for example? There used to be a setting in Firefox to do that, but I can't find it. I'm working with Windows 11-v24H2 on a Dell Inspiron 17 with an Intel Core i7-8550U CPU (about 7 years old) and 16Gb of Ram.........and sometimes I fall asleep waiting for many tabs, windows, and instances of Office 2021 to come back to work (I'm thinking they signed a Union deal, and didn't tell me about it.).

This has been going on and getting progressively worse for about 3-4 months.

Advice? Suggestions? I'd be truly grateful for any ideas you got.

Hello!

After the latest Firefox Desktop updates (not sure which one exactly, since I didn't notice the issue immediately), I've started experiencing a problem with copy-pasting text — specifically with line break formatting on Windows 10.

Instead of copying line breaks using the Windows-style carriage return + line feed (\r\n), Firefox now copies only line feeds (\n). As a result, the text appears as a single long line when pasted into native Windows applications — which breaks the expected formatting. This behavior mainly affects:

  • Text editable fields (e.g., contenteditable or textarea) in modern web applications.
  • Code blocks or snippets (such as in Markdown or monospace) copied using "Copy" buttons (e.g., in ChatGPT or GitHub).

At first, I noticed this only when copying code from ChatGPT using the code-snippet copy button. But now it happens in almost all editable text areas — if I enter text with line breaks manually, and then copy it, those breaks do not appear properly in native Windows apps. For example:

  • In Google Sheets, I often edit text with line breaks in a cell, but when I copy it back, it's all flattened into one line.

Right now, I have to fix this using scripts that replace \n with \r\n, but that's a very inconvenient workaround.

❗My main question is: What changed in Firefox that caused this behavior? This used to be reliable and feels like a regression. It’s a very basic feature and critically important for my daily workflow!

🔧 Follow-up questions:

  1. Can this be fixed in a future Firefox update? Will it be addressed?
  2. Is there a way to fix or configure this behavior right now via browser(settings, configs)?
  3. Is there an extension or workaround that can restore the \r\n format without manual scripting?

Affected apps:

  • ChatGPT
  • Google Spreadsheets
  • Trello
  • ProtonMail (regular text copying)
  • (more)

Thanks in advance for any clarification or suggestions!

I've noticed my GPU fan runs heavily as soon as I open Firefox, and with even just only one browser page open, it runs high speed, where it didn't use to do this. How can I get Firefox from requiring so much of my power. I don't want my electric bill higher just because of a browser. I have a decent GPU good for gaming quality that usually doesn't get clocked enough to cause the fan to turn on and run at high speed unless it's a high-graphics computer game or something. Anything I can do to make the browser demand less on my GPU?

I'm experiencing an issue with the drag and drop functionality in my browser that's significantly affecting my workflow. Previous behavior:

I could drag any selected text to any area of the browser window to open a new search tab I could lightly drag links anywhere to open them in new tabs

Current behavior:

Now I must drag content specifically to the tab bar at the top to open new tabs This extra precision required is frustrating and slowing down my browsing

I haven't intentionally changed any settings, and this change happened suddenly. This functionality was extremely useful for me as I frequently need to open multiple tabs while researching. Has anyone else experienced this issue? Is this a new "feature" or a bug? Most importantly, does anyone know how to restore the previous drag and drop behavior? Thanks in advance for any help or suggestions!

I have Firefox in all my units and it has worked very well over the years. Until I activated Avast SecureLine VPN on my computer HP Microsoft 11.

When the computer is connected to wifi/internet and VPN is activated, the Firefoxprogram won´t start correct. It says I am offline. If I then turn VPN of and update the page it will work immediately. As soon the page start the update I can turn VPN on and it will work on every link and page.

What can I do to get rid of this problem?
