Bug ID: 433609
Summary: The Plsma integration add on for Firefox makes the
system sluggish and unresponsive until it freezes
Product: plasma-browser-integration
Version: unspecified
Platform: Manjaro
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: Firefox
Assignee: k...@privat.broulik.de
Reporter: paul.br...@kde.org
Target Milestone: ---
SUMMARY
When you have multiple tabs open on different pages, media playing in one tab
can make the system sluggish and unresponsive, to the point it becomes unusable
and forces a hard reboot.
STEPS TO REPRODUCE
1. Open multiple tabs
2. Play video in one of the tabs
OBSERVED RESULT
Video freezes, sound skips or repeats, desktop becomes sluggish and
unresponsive. Quickly jumping to a terminal and killing Firefox, allows the
system to gradually come back to normal.
If you do not manage to get to a terminal, the whole system will freeze and the
only option is to power switch to power down.
EXPECTED RESULT
None of the above.
SOFTWARE/OS VERSIONS
Operating System: Manjaro Linux
KDE Plasma Version: 5.20.5
KDE Frameworks Version: 5.78.0
Qt Version: 5.15.2
Kernel Version: 5.10.15-1-MANJARO
OS Type: 64-bit
Processors: 8 × Intel® Core™ i7-6700HQ CPU @ 2.60GHz
Memory: 11,6 GiB of RAM
Graphics Processor: Mesa Intel® HD Graphics 530
ADDITIONAL INFORMATION
To be fair, I do have a lot of tabs open (over 400) spread over 12 different
containers, but, with the Plasma desktop add-on disabled in Firefox, the
problem has disappeared.
