When opening a new tab, bottom row becomes "hidden" behind main window and only becomes revisible when tab on hidden row is closed.
I have the browser set to show five rows of tabs, however, even on the third row (I have not closed enough tabs to test if this happens on the second row), when opening a new tab, the top of the webpage gets moved up to cover the bottom row of tabs, save for a sliver at the top. The only way to re-expose the tabs seems to be to close any tab in the bottom row -- closing tabs in other rows does nothing with the problem.

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
