Large white space above the add-on bar
A large white empty space randomly appears above the add-on bar for some reason. After searching for a solution, i put this in userchrome:
- status-bar {
border-top-width: -1 !important; -moz-appearance: none !important; }
- addonbar {
border-top-width: -1 !important; -moz-appearance: none !important; }
Now at least the white space will be gone when i restart Firefox or open a new tab. But the tab that has the white space will continue showing it until i do something with the window, like show a hidden bar.
Oh and this problem started occurring after i edited browser.cache.memory.capacity and javascript.options.mem.max and gfx.direct2d.disable
Any idea how to completely get rid of this?
