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!

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.

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

There are many tabs open in the firefox window. I'm closing the firefox. I'm opening it again.All tabs opened during the previous opening disappear.Either a new page or a single tab opens. The settings are set to "Open previous windows and tabs" (Image 1)


I go to "Firefox View" ---"Open tabs". (image 2) I see 2-5 windows there.In this case, there are 3 windows.WINDOW 1 is my main window with the tabs that should have been saved and opened when firefox was launched again. I close all tabs from unnecessary windows with a cross.Only window 1 remains. But when restarting, an empty or different window opens again.And again, there are a lot of unnecessary and incomprehensible windows on the list. Previously, a window with restored tabs from the previous session always opened. Question: 1)How can I restore the normal recovery of the previous session when restarting? 2) Tell me.I can somehow switch between windows (Firefox View" ---"Open tabs)(Image 1) Thank you.

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?

I am using FF desktop. All of a sudden, I get no sound through my laptop speakers when trying to watch videos (on YT and FB for example). I still get sound if I use external speakers through the 3.5" jack. I still get sound through other browsers, no matter if it's through the laptop speakers or external ones. So, it is definitely an FF problem. Sound works fine on all other media files on the laptop. Refreshing FF didn't fix it. Nor did reinstalling or restarting the laptop. I tried changing the autoplay settings as suggested in the help article, but still no laptop audio via FF. How can I fix this? Thanks

While I enjoy the capability of selecting a search engine as I see fit, I would prefer that my local drives take precedence. Is there an easy way to enable this for everyday casual use? In other words, can I specify "search local drives first, followed by the web i.e. casting a wider net to search on the world wide web, and an arbitrary third placeholder such as foreign sources (example only) or foreign news items (again, fictitious example)

Any idea how to work round this ?

Problem logging onto Zoho Mail with Firefox.

I have been using both Firefox and Zoho Mail for many years. Now, for some reason, Firefox seems to have a problem completing the Zoho Mail login from the same bookmark I have been using for years, or from a direct URL. The same Firefox installation cannot access Google Maps from a bookmark or directly using a complete URL, but does access some other applications as always.

Now the curious (to me, anyway) part. If I open a new private Firefox window, I can log into both Zoho Mail and Google Maps as I used to from the Firefox private window using bookmarks.

This helps me pinpoint Firefox as the problem – one part working, the other not.

My Firefox is up to date [Version 140.0.4 (64 bit)], and I have scanned all 1,350,000-plus files on my system for viruses and potential startup issues.

Should I reinstall Firefox? If so, how do I do that while keeping my bookmarks and password files?

If I use another browser (i.e., “Google Chrome), I can access both Zoho Mail and Google Maps with no difficulty. That is not a solution for me.

Firefox has been my foundation browser for decades. I don’t want to have to use anything else.
