@blantonradford Thanks for reporting back. That can easily happen: As documented in my previous comments, I had black/white tabs already with FF 50. Most users won't have noticed that because the extension "ubuntu modifications" is installed by default and mitigates this problem for versions _before_ FF51 (or FF51.0.1). However, starting from FF51.0.1 (at least), that extension does not help any more and the issue gets exposed to users. Technically, you hit this issue as soon as E10S gets enabled, be it via update or updating previously E10S-incompatible extensions (like Session Manager) which then become compatible to E10S and therefore allow FF to enable E10S. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1643200 Title: After updating to firefox 50.0, tab goes black instead of showing web pages To manage notifications about this bug go to: https://bugs.launchpad.net/firefox/+bug/1643200/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
