I have HDR working in Proton games and mpv fine (using Plasma 6.4 / Wayland)

I enabled HDR in Firefox (gfx.wayland.hdr), and HDR content works in YouTube fine ( looks amazing!) however.. I have an issue in that all non HDR content doesn’t show any video (I have sound) just a green sceen (see screen shot) including all ads.

Any idea how to work round this ?

I have AMD 7800 GPU .

Cheers

What's up with this? Two fake Trust Wallet add-ins were disabled within the last couple of days after one stole my money and I reported it, and another similar one. They had been pinned to my toolbar and they were subsequently taken off from there with the message that they had violated Mozilla's policies. Now I see that again there are two of them. How can this be prevented? The most obvious sign that these are fake is when one goes to create a new wallet the add-in directs the user to import instead, i.e. it wants to steal private information like recovery phrase.

When I click on NY Times link, I get this message: You have been blocked from The New York Times because we suspect that you're a robot. I'm just an old guy with a low tolerance level for tech glitches. Any help greatly appreciated!

I called NYT Support, which tells me it must be a Firefox issue since I can open in Chrome, Safari. I thought it might because I have the Enhanced Tracking Protection box checked, but unchecking does nothing.

Out of ideas.

When I middle-click a link in Firefox, it opens in a new tab, but it also switches me to that new tab immediately.

I’d prefer to stay on the current tab after middle-clicking, and just have the new tab open in the background just like google chrome does. Is there a setting to stop it from automatically switching?

Thanks!

I received this download from Firefox today, July 22, 2025: xRqj7qhl.html - Size: zero bytes - Kind: HTML text . I've never experienced this before. Is it legitimate? Thanks

I'm getting a PR_CONNECT_RESET_ERROR on my PC when trying to web browse. Same problem with other browsers. Was working fine till a few days ago The URL box has 'Not Secure' before each URL address I try. Have looked up solutions on YT to no avail eg clearing cache etc

My Laptop has no problem with this.

I use an independent password manager to store my passwords and prefer it over Firefox's because it has a highly customizable generator for creating new passwords. However whenever I am on a new site, Firefox pops up with a prompt to generate a secure new password (it appears as a drop-down from the item text box). My password manager also creates a pop up/drop down, but it is hidden behind Firefox's and I cannot access it. I need to be able to disable the secure password generator prompt. Please take a look at my excellently annotated screenshot, attached.

I don't know if this ever worked in FF, since I've been on Chrome a while. I tried canvas.toBlob() in FF without a solution.

The behavior is the same whether the served image is jpg or webp. A Servlet delivers the image data, here in webp:

          response.setHeader("Content-Type", "image/webp");

On page, I use a canvas thus => see '// FIREFOX'

     var canvas = document.createElement( 'canvas' );
     canvas.width = width;
     canvas.height = avail_height;
     var context = canvas.getContext( '2d' );
     context.drawImage( imgsrc, 0, 0, width, avail_height);
     context.lineWidth = 150;

     // FIREFOX: canvas.toDataURL('image/jpeg')=black, png,webp,default=transparent
     img.src = canvas.toDataURL('image/jpeg');

     img.onmousedown = disableDragging; // for FF
     img.style.opacity = "1.0";
     console.log('setImg ok');

Inspecting a black jpeg:

        data:image/jpeg;base64,...

Thanks!

Before upgrading to Firefox 140, I would always quickly switch between my default DuckDuckGo and alternative search options, like Wikipedia, using the up and down arrows. I would just type the search term in the address bar and then tap the down key a couple of times before pressing enter if I wanted to use a different search engine.

The new address bar no longer seems to offer this option. I see I can still select alternative search engines using the mouse, but pressing the down key no longer lets me select them.

Is it possible to re-enable this way of quickly switching between search engines using the keyboard?

Whenever i search something on google, firefox desktop (all fine on android) is failing to display the ai(gemini) answer no matter what questions i ask.

Same happens in the "AI Mode" option that is available in google's recent update.

And, I,m logged in.

This started since a week, everything was working fine before that.

Adding the images below.

Hello,

I'm writing because I’ve encountered an issue with the tab groups feature in Firefox.

Some time ago, after a browser update, I noticed a new feature that allowed me to group tabs thematically — I could name each group (e.g., "Study", "Work"), choose a color for it, and save and close groups to reopen them later. I found it very useful and used it a lot.

Last night, I decided to declutter my browser and closed several tab groups using the built-in menu. A bit later, I shut down my computer, but perhaps too quickly. This morning, when I turned my computer back on, Firefox was very slow to start. After a restart, everything seemed to work fine again, and the open tabs were restored.

However, all my previously saved (but temporarily closed) tab groups disappeared. In the tab group menu, I can now only see the ones currently open. I’ve searched through all the settings and history but cannot find any way to restore the missing groups.

Is there any way to recover the tab groups that I had previously saved and closed?

Thank you very much in advance!

Application error: a client-side exception has occurred while loading (see the browser console for more information).

where is the browser console? how do i fix it never had an issue with until the last two days?

After upgrading my 128 esr to 140 esr, some sites stopped opening. In regular versions, it has not opened for a long time. There are many such sites, for example, qwen3.app or temp-mail.io. It thinks for a long time and finally a message that the time has expired. Chromium is ok.

Recently, after the newest Windows 11 update, Twitch hasn't been loading correctly, the tab looks as if it finished loading, but the page gets stuck in endless loading, no other site has this problem, and it happens even opening links to Twitch channels directly. I've added and screenshot of the problem.

I'd love some help or at least know if this is a problem on Twitches end or not. Thanks.

For the past 2 months I've found it very difficult to sign into my Hotmail account using Firefox. Microsoft keep telling me to use a VPN or another device. I like answering emails on my computer because of its large screen. I've tried signing in about 2000 times now. Firefox told me they can't help me because I'm not a Mozilla subscriber even though they own Firefox. Microsoft told me it's Mozilla's problem. Can anyone help me please. John in the Philippines.

I have a profile that causes odd behavior, within the profile, and to the OS.

Regarding the profile itself:

1. I use Multiple Tab Handler, which should allow me to move tabs on the tab bar with the mouse, but it does not (see image of proper behavior)

2. Normally, i can drag this padlock button to the desktop to create a shortcut. but now, it will not move/drag (see image 2)

3. I also have a backup profile from several months ago that has none of the above symptoms. However, If I substitute it's sessionstore.jsonlz4 file with the the one from the problematic profile, all the bad behavior mentioned above re-emerges.

I know this sounds strange, but, I also get external display issues when using the broken profile. These events are random, and manifest themselves differently, so I can't duplicate them. Essentially, these snips are examples of images from the taskbar tabs, or the clock area, suddenly superimposing themselves on the top portions of the taskbar toolbar area.

This is the view of my clock area (see next image 3)

In the following image, imagine that the portion on the left, that opens the start menu, is now hidden under what looks exactly like the clock area on the right, superimposed over it (see next image 4)

Those aberrations are removed by simply moving the mouse cursor over them, but they will continue to occur in any number of variations over any area of that top toolbar.

Is there a Session Manager that will save the session, to be later restored into that previous profile, but not also pass along the corruption?
