I would like the know how to increase and/or decrease the size of my navigation and menu bars. Not of the text but the bars themselves. It has happened to me twice now where, during my normal browsing, instead of zooming the webpage in and out I somehow zoom the navigation bar. This resulted the first time in a navigation and menu bar so tiny they were almost impossible to read. A complete un- and re-install of the browser fixed it, but it happened again recently. Only this time my Navigation, Menu, and Bookmarks bar are twice their size. I don't know what in my mouse movement's triggered the changes, as I have tried to repeat the effect on purpose and failed. I've looked in aboug:config but none of the 'layout' preferences show any user modification and are all on their default settings. Right now my bars are so large that they're annoying. And if it helps narrow down what's going on, the size changes also affected the writing inside the bars, making them smaller/larger.
