Hello, Are you still able to reproduce this in latest versions of Firefox and Ubuntu?
Also, can you please check if you might have 'letterboxing' enabled by any chance? This might be a side-effect of enabled letterboxing. To check that, open 'about:config' and see if you have a 'privacy.resistFingerprinting.letterboxing' setting with a value of 'true'. Also, another possible cause I'd heard over the years is some adblock extensions. If you have any installed, can you try disabling it and see if it helps? If that happens to be the culprit, you may want to try using uBlock Origin, which has been solid and I've never heard any similar reports about it. If none of the above and you can still reproduce this, would you please open a bug report on Mozilla's tracker at https://bugzilla.mozilla.org ? ** Changed in: firefox (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2047760 Title: Empty band at the bottom To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/2047760/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
