I have a top panel that I set to auto-hide. In Firefox fullscreen mode (F11), the tabs auto-hide after a certain time. Normally, you would have access to the hidden tabs by hovering your mouse to the top of the screen. I can't get to see the tabs when my KDE top panel is set to auto-hide as if it blocked the Firefox tabs. It works again as expected when I disable the option in the KDE panel. I use Firefox 20.0.1 (gentoo ~amd64) and Plasma Workspace 4.10.2 (stable gentoo). Reproducible: Always Steps to Reproduce: 1. Add a panel to the top. 2. Set that panel to auto-hide. 3. Launch Firefox and get in fullscreen mode (F11). 4. Try to access the tabs bar. (Not expected) 5. Now remove the auto-hide feature on the KDE panel. 6. Repeat 3 and 4. (Expected) Actual Results: The tabs and menu bars do not show in Firefox. Expected Results: The tabs and menu bar should have slided down.
