Public bug reported: Firefox has started making the default state to Multiprocess starting with Firefox 48. Right now, at least half the Firefox users have Multiprocess enabled by default and the performance and stability benefits are quite substantial. More about Multiprocess here - https://wiki.mozilla.org/Firefox/multiprocess
The Ubufox extension that comes installed by default in Ubuntu's Firefox disables Multiprocess, due it not being compatible with it (check attachment). This leads to all Ubuntu users not benefiting from the performance benefits of Firefox multiprocess architecture and also the ever increasing benefits as they keep improving it. ** Affects: firefox (Ubuntu) Importance: Undecided Status: New ** Affects: ubufox (Ubuntu) Importance: Undecided Status: New ** Tags: packaging ** Attachment added: "Ubufox extension disables Firefox Multiprocess" https://bugs.launchpad.net/bugs/1658407/+attachment/4807405/+files/Multiprocess-firefox-disabled.png ** Also affects: ubufox (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1658407 Title: "Ubuntu modification" extension default package disables Multiprocess in Firefox To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1658407/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
