I found a problem with McAfee Webadvisor 13 Aug 2025 release. It causes flickering in the upper right part of the screen. Disabling it in Extensions fixes the problem. Removing it and reinstalling causes the problem to reoccur. This is new, had no problems yesterday but today all four of my family's computers have this problem. I will report the problem to McAfee and give an update if I get a response.

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!

All of a sudden this evening my title bar is shimmying left to right. If I try to pull down the Bookmarks/History/Downloads box it shimmies, too. I have no idea what caused this to happen and no idea how to fix it. I looked in the Task Manager but I'm not sure anything odd is in there. I ran a scan with McAfee but it didn't pick up anything. I am hoping someone out there can help me with this. I got rid of cache and history. Maybe it's a cookie issue and I should get rid of all of those, too?

I recently bought a new computer, and I'm trying to get everything transferred from my laptop to it. I have a Firefox account, am signed in on both devices, sync is turned on, and passwords are set to sync. I don't know how, but all of my passwords are on my new computer, but not on my laptop and I can't figure out how to get them back. Maybe I messed something up trying to get all of my tabs transferred? It wouldn't be a problem if I was completely done with my laptop, but I'm still going back and forth between the two.

Also, it seems that the passwords on my new computer aren't the most up to date, as I'm signed in to several websites on my laptop, that won't accept the passwords on my new computer.

I would really appreciate any help getting this all straightened out.

Hello,

I've been having this problem recently on Windows 11 with Firefox, where switching my input language to japanese (ALT + SHIFT keys) causes the browser to crash immediately. This happens about half to one third of the times I do it. It didn't happen before and I'm rather confused.

Searching on Google brought up a few similar experiences, such as this one, but the suggested fix (switching intl.tsf.enable to false on the about:config page) didn't work for me.

Any help is appreciated! Thank you very much in advance 😊

bold textUsing beta it became flaky so I tried to move to the release version. I was told the beta was a later version so I could not. When I reopened FF all my data is gone. I lost all index page formatting, bookmarks, history tags everything. I would like to have this back (even beta)

I have an older RAID system that I need to login to from a browser. Is there a way to remove the TLS 1.2 protocol for local NAS drives that are only 2 feet away but I can not connect anymore.

When adding an extension, the icon doesnt appear in the tool bar, and is not visible in the customisation menu of the tool bar. It's also impossible to take an extension icon off the tool bar (customisation menu).

Hello, I’m having trouble getting Firefox to work properly on my computer. During installation, the setup process becomes very slow, and once I manage to install it, Firefox hangs or becomes unresponsive within a few seconds after launching.

My system details:

Operating System: Windows 10 64-bit

What I’ve tried so far:

Reinstalling Firefox Running in Safe Mode Clearing profile data Disabling antivirus temporarily

None of these steps solved the problem. There are no specific error messages — the browser just freezes, and I have to close it via Task Manager.

Up until last week, I was able to get pop-up ads in Digg's Adventure. I went into the settings in Firefox and I have the pop-up ads unchecked. It still doesn't allow me to get prizes from ads. Is there something I can do to fix this? Can you help?

Something or somebody emptied my bookmarks. I tried the import/restore routine but was told that Firefox "was unable to process the backup file." I also tried System Restore without success. Can you help me? I don't want to leave Firefox, but the problem reoccurs, which is maddening and time-wasting. Thanks, Bruce Berckman

For the past several days I click on PRINT and it reads PREPARING PREVIEW . it goes on and on and never prints. I get a message from Firefox that says they are repairing some troubles?
