Hello, Since I was unable to reproduce this issue in first place, I cannot confirm if it's indeed fixed or not.
Tried to reproduce it using Firefox 67.0, 75.0, 76.0b4 and 73.0a1 (2020-01-01) on multiple Ubuntu 18.04 x64 machines with the STR found in this bug and within the duplicates, I’ve also used a Firefox 68.7.0esr build from Ubuntu Store. It worked fine on each attempt, Firefox worked as expected. I assume this might also be related to the older Chromium/Chrome versions that were available within that timeframe. The Chromium version that is installed on the machines I've used is 81.0.4044.122. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1870827 Title: Firefox hangs after simultaneously opening Chrome/Electron-based applications To manage notifications about this bug go to: https://bugs.launchpad.net/firefox/+bug/1870827/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
