Created attachment 9174007 'GTK_IS_STYLE_CONTEXT (context)' failed Hi,
On Ubuntu 16.04 LTS I downloaded FF Nightly 82.0a1 (2020-08-28) (64-bit), opened it from a terminal with the command ./firefox -p and I did not see the error message. But when I closed the browser and ran the same command again, hence restarting and updating nightly to 82.0a1 (2020-09-04) (64-bit), I saw the attached error messages. How should we proceed? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1893021 Title: Flash plugin symbol lookup error with firefox 80.0+build2 on xenial (gtk_window_set_titlebar) Status in Mozilla Firefox: Fix Released Status in firefox package in Ubuntu: Fix Released Bug description: When testing firefox 80.0+build2 on xenial (from https://launchpad.net /~ubuntu-mozilla-security/+archive/ubuntu/ppa/+packages), I'm observing that the flash plugin (installed by flashplugin-installer) doesn't work. This appears to affect only xenial, flash is working in the bionic and focal builds.
