Firefox Community Forum

In the last few days, after some minutes of usage, parts of Firefox become unclickable:

- I can still click on tabs to change tabs. - When hovering over the cross button to close a tab, it changes appearance as it should. Clicking the button does nothing. Ctrl+w still closes the button. - Clicking on the address bar does nothing. - Cannot click on back, forward, refresh buttons. - Cannot click on any add-ons. - Cannot click on preferences. - Can click on the button to open a new tab. There, I can enter an address. Once the page has loaded, address bar becomes unclickable again. - Bookmarks toolbar is still working as expected. - Keyboard shortcuts (ctrl+t, ctrl-w, ctrl-l) still work as expected.

I'm running ``` Mozilla Firefox 138.0 20250428130755 20250428130755 ```

on Manjaro 25.0.1 with GNOME 48

Since new update was installed today, in touch screen mode, every time a touch a link of any kind my touch keyboard pops up. This is very annoying. Where can I find the setting to turn off this option?

I thought it was an issue with my pc, but chrome does not have this issue and neither do other applications. I have tried clearing my cache and cookies as well as ensuring mozilla was using my computer performance settings as opposed to hardware acceleration. The attached images are a very small example of the issue. Typically, after clicking on the screen or pressing a button the text is corrected but often replaced with new text being "corrupted". Any help would be greatly appreciated.

Firefox keeps crashing and Hanging and I get the error message "gah your tab etc" I have followed the advice for fixing the problem but it keeps coming back Its really annoying when you are trying to do something I'm no computer whiz and I have looked at the crash reports, its just gobble gook to me, I need help to fix the problem.

Along with many other Firefox users, I have a long-term problem with a PR_END_OF_FILE_ERROR in Firefox. How can Mozilla Support fix this problem for me? Can you send a link with the solution, or something?

Thank you, Joseph Seecchack, [edited] @aol,com. I eagerly await your response.

I’ve noticed that Firefox consumes a lot of memory, especially when I have multiple tabs open. Sometimes, it slows down my entire system, and Task Manager shows Firefox using over 1GB of RAM even with just a few tabs. Other browsers like Chrome or Edge seem to handle memory better with the same number of tabs.

I’ve tried restarting Firefox, closing unused tabs, and disabling a few extensions, but the problem keeps coming back. I even checked techsquest.com for tips, but I’m still struggling. Are there specific settings, hidden features, or optimizations I can apply to reduce Firefox’s memory usage without sacrificing performance?

Here’s what I’ve already checked:

Firefox is updated to the latest version.

No unusual extensions running (just uBlock Origin and Dark Reader).

Hardware acceleration is enabled.

Any help would be appreciated—thanks in advance!

Hello,

I checked the troubleshoot and gave all the necesarry permissions on my Mac for Google Meet to use my screen (allowed audio, video and screen recording). Nevertheless, I cannot manage to share my screen on Google Meet. As shown in the screenshot, it offers the option to share my whole screen (I cannot select a window or a tab...) but for my audience neither this is working.

Could you please help me fix this?

Many thanks in advance!

This is a problem I only started experiencing yesterday, but if I try to upload an image to a website (such as social media), and I double-click a shortcut for a folder, it attempts to upload the shortcut as the selected file, instead of opening the folder.

This is only a problem with firefox, as I tried doing this in another browser and I was able to open it as a folder normally. Any ideas on what could be causing this or how to fix this?

Here is something I have never ran into, for some reason suddenly today, I am only able to load about half the websites I try to load. A blank page loads that says "Hmm we're having trouble finding that site". But the tab says "Server not found". Again it's only some pages that won't load.

It does not matter if I click the bookmark, or type in the address,it's always the same pages every time. I tried 19 sites, (10 bookmarks, and 9 typed), plus typing in some of the bookmarks also.

If I change over to Chrome, or any other browser those pages will load. If I use Firefox Mobile, those pages load. Something has gotten messed up in my PC settings, or something.

I have tried clearing the cache, the history, and the cookies, no luck. I restarted into safe mode, and had the same problem.

It's been forever since I had any problems with FIrefox, and must admit I have forgotten most of the troubleshooting tips, that I used to know. But I did remember those, unfortunately none of those are the problem.

What else can I try? Thanks in advance.

BTW: I am submitting this on my phone because this is one site that won't load. If it did I would, I would click the "Share Data" button.

I have two Firefox tabs open on my browser. Task manager shows 35 tabs using 897 MB of memory. How do I make this stop? And why are so many tabs running? I have cleared cache, cookies, etc.

I have Firefox version 136.0.2. I think it was quite recently updated. The right click menu is broken. The choice list is much longer, and the choices "open link in new tab" and "copy link" (ones I tried) do not work. This only started happening this morning. Right click works fine in Chrome. Screenshot included.

Hello,

Two things:

1. When I open a link in Firefox, the back button will not work taking me back to the page before.

2. I want to be able to open another page with another page open.

Any advice or suggestions appreciated,

Don

Hello!

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?

Attachment is a screenshot shows task manger shows there are 64 open files open, when I have only 4 windows open. What would causing this?

Over night Firefox closes and close all my open windows. I need the windows remain open.

Thank you for sharing your wisdom with me.

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!

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!

After the last update, the mouse wheel in the browser stopped working. This is very inconvenient, the pages do not scroll with the mouse wheel, only with the arrows on the keyboard.
