I have a local HTML/Javascript document I use for compressing local image files. It relies on HTMLCanvasElement.toBlob() to achieve the compression in the usual way; a pertinent excerpt:

                   const output = document.getElementById("outputDiv");
                   const blobURL = URL.createObjectURL(file);
                   const img = new Image();
                   img.src = blobURL;
                   // ...
                   img.onload = function () {
                       URL.revokeObjectURL(this.src);
                       const canvas = document.createElement("canvas");
                       canvas.width = img.width;
                       canvas.height = img.height;
                       const ctx = canvas.getContext("2d");
                       ctx.drawImage(img, 0, 0, img.width, img.height);
                       canvas.toBlob(
                           (blob) => {
                               const anchor = document.createElement("a");
                               anchor.download = getNewFileName(file.name); /* uses extension .webm for .webm, .jpg for everything else */
                               anchor.href = URL.createObjectURL(blob);
                               anchor.textContent = "DOWNLOAD";
                               output.append(anchor);
                           },
                           mime,  /* set earlier based on file extension: .webm -> "image/webm", everything else -> "image/jpeg"
                           quality / 100    /* (user-specified) */
                       );
                   };

Here's the quirky thing, though: when I'm compressing, say, a .jpeg file (or a .png), clicking on the download link opens a save-file dialog, but when using a .webm file, it opens the compressed image in a new tab! True, I can always then save the image from there (the resulting file is in Firefox's temp folder), but I don't understand the difference in behavior -- and indeed, in at least one other browser I tried (the latest Vivaldi) the download happens as expected regardless of input file type. In all cases the anchor hrefs look like, e.g., "blob:null/724ab85e-53ba-4890-9868-7f1ba27d4278".

Any idea why this is happening? I highly doubt it's the intended behavior.

Browser: Firefox 132.0.2 for Windows. Environment: Windows 10 Home 22H2 version 10.0.19045.

FF v132.0.2 (64-bit). We utilize Sharepoint/Microsoft 365, and since switching to Firefox, the zoom controls normally located in the lower righthand corner for Excel spreadsheets is just gone. This is with extensions disabled, even tried Private View. Chrome properly shows it.

Screenshots attached showing Firefox/Chrome. That basically eliminates our ability to use FireFox if that's the case since there's no other way to do it.

I'm logged in to my Firefox account, I visit (for example) ESPN.com on my PC. I adjust the size to fit my PC screen, then when I visit the same site on my laptop the website doesn't look right so I have to size down, but then when I visit on my PC I have to size up again etc etc etc.

I want to individualize the size of webpages, how do I do that?

Firefox automatically adding the https to our internat Intranet and I cannot access it. Auto adding the https is off. This site is only available within our firewall. I have had access forever until recent updates have made it impossible to access it.

I type in the URL: ourintranet/ and that has always gone to the site. Now, it is changing it to https://ourintranet/ when I hit enter...never done this before. I have this setting: Don’t enable HTTPS-Only Mode enabled.

I beleive in the recent versions of Firefox, shortcut keys have been added/changed such that holding the Option key while in the URL Search bar activates other functions (Switching search engines: Option + Up/Down Arrow) and completely disables my ability to move left or right through the URL by word.

Is there any way I can disable this shortcut key combination?

I just had a suggestion regarding settings that you set. I would like to know if there is any feature being worked on to be able to save all your settings (or maybe even back up) to your login? or back them up to a file that can be imported later? or is there one that i'm missing? I have a custom toolbar and any time I log in to a different computer where I have to install firefox again...I would rather have an import function for all my settings/toolbars

I starting having trouble getting Firefox to open last week on a win 10 PC. I could only open a window if I ran as administrator. If I got a window open, then it would not go to any website I tried. I thought it was issues with my PC because it is old and I was having other issues as well. I got a new Win 11 PC and fire fox opened when I first downloaded it but now, I can't get it to open again. It is my preferred browser of choice. Any help on this? TIA, Stephanie
