debian 11.3 not working

firefox aways crashes when i had enabled this add-on

unuse , share is ff self.

Causes memory leak that causes both plasma-shell and firefox to gradually use more and more memory. Uninstalling Plasma Integration in the browser fixed this. Within 3 days of use, both Firefox and plasma-shell take up 5~GiB of memory.

Kills all thumbnails on all browser windows by showing the video thumbnail and player controls - even on windows that have a different web page loaded, or even after you went away from the video onto another page. It can also not handle multiple tabs / windows with different videos.
In its current form a clear downgrade to the regular functionality of previewing the current webpage of the window.

Firefox broken after installation of this addon

não funciona direito a integração nomeu computador

Its not running on firefox 64 and Manjaro 18.0 - Kernel Linux 4.19.12 - Plasma 5.14.

Some sites like my e-news paper hang when I use the KDE integration. This was for me the reason to uninstall.
