I just updated to 143.0.3, and unless I open FF to its full width now, my clear-browsing-data and zoom icons have been disappeared from my menu bar. The reason is because large (one-inch!) empty spaces have suddenly been inserted at the far left end of the menu bar (next to the back arrow) and between the hamburger icon and minimize "-" sign. It's not possible to remove those blanks via customize. I click on my "clear" and "zoom" icons hundreds of times a day and I prefer having my browser non-full-width (prefer 2/3 width). Anyone know what caused this and/or how to fix it (apart from rolling back to 142). Once again Mozilla has broken something that worked perfectly for me for many years and I suspect it has something to do with more screwing around with tabs. (I do use a CSS file solely to keep tabs on bottom.) Alternatively, is there a way to shorten the address bar? That might create room for my add-on icons to re-appear while leaving the spurious blank spaces on the menu bar. Thanks in advance! --KK
