Firefox on Windows 11 has suddenly and without my apparent action started automatically hiding the tab bar and the address bar to give all the vertical space to the current tab. I do not like this (I have big monitors and I want those bars always visible)

How do I turn this one and why did it turn on in the first place?

Thank you for having the Q&A facility.

My toolbar is visible when I click on the 'Open a new tab' plus sign at the top. But if I go to a site, either from a search or from bookmarks, the toolbar disappears.

I just (yesterday) had to delete profile, delete bookmarks, delete Firefox, install Firefox, in order to get it where it would save bookmarks again. The toolbar, prior to that, did NOT disappear when I went to a new site.

Please help.

Drop Down Menu On Certain Websites Won't Work

I recently ported from chrome to firefox about 3 days ago and was tryin to access the dropdown menus on this website https://www2.gov.bc.ca/gov/content/governments/government-id/bc-services-card/your-card/get-a-card

I realized it wasn't working so I turned off my adblocker (ublock origin), refreshed the site and still not working.

Also attempted to use troubleshoot mode and still does not work.

Cleared cache + cookies and used troubleshoot mode and nothing working still.

I lastly checked the website was working by opening the same link on chrome after all that and it works perfectly fine over there. Any ideas what could possibly be the issue?? I basically have a fresh install of firefox with no changed settings besides anything that might of been copied over from Chrome when firefox automatically asks you to migrate your stuff over, and used the troubleshoot mode + clearing cookies and cache

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!

Images from canvas black or transparent: img.src = canvas.toDataURL(); // FF: 'image/jpeg'=black. Png,webp,default=transparent.

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!

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 .
