Before upgrading to 20.04, I routinely opened batches of websites by copy/pasting from a spreadsheet full of URLs into a terminal. For example:
firefox nytimes.com &
firefox google.com &
Each site would load in a new tab. (In an existing window if firefox was already open.)
This now fails. For firefox, vivaldi, brave...
If Firefox is already running, this error message pops up:
"Firefox is already running, but is not responding. To use Firefox, you must first close the existing Firefox process, restart your device, or use a different profile."
(...where it did not before. New tabs used to appear in my existing session.)
Why? Fix?
