If Preferences is left when Privacy tab is active, entering back to Preferences shows all of Preferences. So the solution is to have "height:..." in all operating systems. I don't if this is problem for en-US, but I'm forced to add height in Bulgarian (bg) l10n. Reproducible: Always Steps to Reproduce: 1. In Linux, go to Preferences / General 2. Leave Preferences 3. Enter Preferences (it's in General tab) 4. Go to Privacy tab 5. (there is no enough height) Actual Results: Height of Preferences depends on last visited tab. Expected Results: Height of Preferences cover all tabs. All this is in bg l10n but I think this is a general issue.
The UNIX problems are known, this is a duplicate. As for Mac, the prefwindow dynamically resizes like a normal Mac prefwindow, so specifying a fixed height is just plain wrong.
