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

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.

Warning: Potential Security Risk Ahead

Firefox detected a potential security threat and did not continue to search-crown.com. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

What can you do about it?

The issue is most likely with the website, and there is nothing you can do to resolve it.

If you are on a corporate network or using antivirus software, you can reach out to the support teams for assistance. You can also notify the website’s administrator about the problem.

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 .

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.

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!

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.

Hello all:

Just downloaded version 140 and ran into an immediate "visual/appearance" problem with regard to the background color(s) of the sidebar bookmarks view. Many themes now have totally dark sidebar colors and not readable (see screenshot image upload with this posting). I always have my bookmarks (almost 1200 of them) displayed in my sidebar, and this is the first time an issue like this has arisen with a Firefox update.

To remedy this scenario, I must use very light colored themes that have a white background when you bring up the sidebar bookmarks. If not, everything is totally dark and unreadable.

Any ideas or help on this one?

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!

As a stakeholder, I am unhappy with Anthony Enzor-DeMeo's ideas to incorporate more AI into the Firefox browser in the future. Most internet browsers are using AI nowadays, and I think Firefox's lack of AI makes it a very appealing browser for users. This is because new AI technology annoys many people. As other browsers continue to incorperate more and more AI, this will increase Firefox's appeal for users who are annoyed with AI.

Overall, I think Firefox will be a much better browser if it does not incorperate AI. It will mean a lot to me if these concerns are taken into account. Thank you for all that you have done.

Sincerely, Eli Buikema

I am using Firefox v140.0.1 Snap on Kubuntu 25.04, Kernel 6.14. Since the Firefox update in the past couple days, the mouse cursor has started appearing huge and slightly blurry (as though the image is scaled up) in Firefox and nowhere else. The size is visually annoying, and occasionally difficult to know exactly where I'm clicking (trying to move the caret in a text box for example). It also appears to be a different style from the main desktop cursor, the shape and color are ever so slightly different, but this may already have been the case and I simply didn't notice because of the previously small size. Firefox doesn't have its own built in cursor settings that I can find, nor obey the system cursor settings. I have a high DPI display so perhaps it is being over-compensated for? e.g. both the system and Firefox are scaling the cursor up, assuming the other hasn't done it already, resulting in a cursor that's too big.

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!

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.

Hello:

I'm not certain if this question comes under Firefox or not:

How do you stop a specific computer software program-app pop-up notification (popping out from the lower right corner of your computer)?

As an example, I have a utility program, IOBIT Malware System Care that pops-up various notifications such as "update notice," "renew," "discount sale" or whatever notice or ads that is 'pushed'.

-I went to my Windows 11 list of installed app "notifications" and this program is not listed. -I tried contacting tech support but they haven't responded. -I went to Firefox 'Settings' -> Privacy & Security->Permissions and then I opened up 'Exceptions' to see if I can block something. It wants me to put in a specific website. The issue is not a website but coming within a software / app program.

So how and where do I stop a "pushed' notification? I assume it's coming in via my browser / Firefox?

Thank you in advance,

Steven

The release notes for Firefox version 140.0.1 indicate the extension button can can now be removed from the toolbar.the noes say:

"Firefox Extensions: Customize your toolbar with the option to remove the extensions shortcut, giving you more control over your browser. When the button is hidden, you can access the extensions panel again at any time from the Firefox menu by clicking the Extensions menu item."

I still cannot drag the button down and out of sight by customising the toolbar.

Suggestions welcome.

My old Firefox on my desk top has a home icon to go back to the home page. This new Firefox on my laptop doesn't seem to have one? What am I missing? How do I get back to the home page?

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?

Since recently 1~2 version, my Firefox keeps consume large amount of memory and release it repeatedly

Even I restart Firefox and do nothing, it will start doing this again

I use about:processes and about:memory to capture this seems the main process's "tab.query" causing this, please check

PS: sometime it will consume till system max (64GB) and cause my OS out of memory. PS2: that wave-like memory usage is cause by Firefox
