The app sizes two adjacent images to the same height. Maybe there's a better approach?

This works, in that I see the original image displayed at the wrong size:

   //img.src = imgsrc.src;

This sizes the image but without the data (black square for toDataURL w/ image/jpeg) in FF, but not Chrome and Safari:

   var canvas = document.createElement( 'canvas' );
   canvas.width = width;
   canvas.height = avail_height;
   var context = canvas.getContext( '2d' );
   // Tried/failed: Fill white background for JPEG export
   //context.fillStyle = '#fff';
   //context.fillRect(0, 0, canvas.width, canvas.height);
   context.drawImage( imgsrc, 0, 0, canvas.width, canvas.height);
   context.lineWidth = 150; // ??
   img.src = canvas.toDataURL('image/jpeg', 0.92);
   img.onmousedown = disableDragging; // for FF
   img.style.opacity = "1.0"

The page is the view.html one gets to via Enter on phobrain.com.

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 was asked to create a new profile in order to keep using Firefox, despite never having an account. After I clicked okay, it opened the new version of Firefox, but without all the passwords, bookmarks and history of the past few years. This is really inconvenient. I have since then made an account, but the fact that I can't find any of this data anywhere has me worried that every time I update Firefox it will wipe my account.

I keep a lot of tabs open (~60) in any particular session - I find it's faster in this way to get back to a site.

About every six months or so, I lose *all* these tabs because of Firefox's inadequate session backup system. It only saves two or three total backups, some of which are completely out of date. But the worst scenario is when (1) some site pops up a new window; (2) I mistakenly close my main window before the new window; (3) I open this new saved window once or twice by accident, causing my 60-tab session backup to be overwritten.

Using a third-party session manager (I have tried all the well-known ones) can mitigate this problem, but doesn't really solve it because the re-opened sessions aren't quite in the same format as Firefox sessions and so lose information. In particular, I often lose each tab's icon as well as metadata for Tree Style Tab.

Could Mozilla please consider a more robust session backup system for Firefox? All it would take (I think) is to allow the user to choose the total number of backup sessions and the frequency at which a new session is added. Thank you!
