Firefox has a global scaling setting that can enlarge everything proportionally, including tabs and their text, text in the address bar, and on the web, as well as the bookmarks? If you want to try it, here are the details: (1) In a new tab, type or paste '''about:config''' in the address bar and press Enter. Click the button promising to be careful. (2) In the search box in the page, type or paste '''devp''' and pause while the list is filtered (3) Double-click '''layout.css.devPixelsPerPx''' and change its value to '''2''' then press Return or click the blue button to change the change. ''Note: the default value is -1.0 but do not use the - on your values.'' The text should enlarge by 200% compared with the base value. Your base value might be 100% - 125% depending on your Windows settings, but either way, it should be dramatic. Too big, try 1.5 or 1.75. ''Note for Mac users with a Retina (double-resolution) display: your base value is 2.0, so you won't notice a difference until you dial in a higher number.'' Please be careful not to select too low a value to avoid everything becoming tiny. If that happens, hold down the Ctrl key and tap the + key several times until you can see the Reset button (arching left-pointing arrow at the right end of the bar) and click that to return to normal. Then hold down the Ctrl key and tap 0 (that's zero) to reset the zoom and you can start again. Can you get it to a size you like?
