Public bug reported:
Lubuntu resolute is running live.
I want background sounds whilst I delete files prior to actual install
i'll run, i got annoyed by vlc so switched to firefox to stream stuff
from youtube...
advert appeared; so I opened a settings tab by menu top right; instantly
firefox freezes
this behavior (this run anyway) can be easily re-created; new tab of
settings & whilst background tabs will continue a short while (if they
have music etc running on them), but you've lost access to using current
tab & background tabs soon run out of cache & firefox goes silent
(audibly)
** expected behavior
I can peruse settings and make changes to suit my tastes
** actual behavior
firefox just freezes & needs to be killed at terminal
-- messages when run from qterminal
lubuntu@lubuntu:~$ firefox
