How to inspect browser's XUL?

I need to inspect browser's UI (tabs bar etc.) to make userChrome.css, but there's no up-to-date info about doing it in current FF to be found anywhere.

I have a Mac that was running Sequoia 10.14.7 I think. Firefox hasn't been giving search results since yesterday so I updated Firefox and restarted it. Still got blank pages after updating. Firefox suggested re-installing so I did. I got no warning DURING installation that the newest version would not work with Sequoia. There was a light gray circle slash through the icon when I installed it, but have never see that when installing apps before. I was given an option to replace the original Firefox or install a second version, so I chose "replace," thinking I was keeping it simple. I updated Mac OS to Catalina 10.15.7--an action I've been avoiding due to all of my most important documents being on an older version of Word for Mac 2011, and TBH I resent having to pay for a subscription to access my Word & Excel documents for revision or printing, and don't like keeping my documents on the cloud...as required by newer versions of MS Office. Now I have Catalina & the newest version of Firefox and can't do the two most important things I need to do on my computer: Work with my Word docs and Firefox STILL PRODUCES BLANK SEARCH RESULTS PAGES. I've now essentially lost access to all my Office docs due to chain reaction fuster cluck resulting from a blank Firefox search page 2 hours ago. PLEASE ADVISE.

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 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?
