Bug ID: 495982
Summary: Snap-based firefox can fail to pop up the permissions
box -- suggested documentation fix
Classification: Plasma
Product: plasma-browser-integration
Version: unspecified
Platform: Ubuntu
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Firefox
Assignee: k...@privat.broulik.de
Reporter: hwert...@gmail.com
Target Milestone: ---
SUMMARY
On some Ubuntu installs, Firefox (or snap, whichever should be responsible)
never gives a notice about allowing browser extension integration (with native
host), and just denies it. plasma-browser-integration is basically entirely a
bridge between firefox and "native host" KDE, so it renders the extension
non-functional. There's a workaround, which I suggest putting into the
documentation.
STEPS TO REPRODUCE
1. Choose the notice on the KDE notification area to install KDE plasma
integration
2. Install the extension
3. Notification bar still has notice to install the plasma integration, and
it's controls in Firefox indicate "failure to connect to the native host".
OBSERVED RESULT
See STEPS TO REPRODUCE
EXPECTED RESULT
It should ask for permission then be all nicely integrated.
SOFTWARE/OS VERSIONS
(available in the Info Center app, or by running `kinfo` in a terminal window)
Linux/KDE Plasma: Ubuntu 22.04
KDE Plasma Version: 5.24.7
KDE Frameworks Version: 5.92.0
Qt Version: 5.15.3
Kernel 6.8.0-45-generic (64-bit)
Graphics Platform: X11
ADDITIONAL INFORMATION
My Ubuntu 22.04 install has been multiply upgraded -- I assume something
"broke" during one of the upgrades that it never asks for permission for native
host integration for extensions... when I first had this happen (with Video
DownloadHelper) I assumed it was some one-off problem I had, but it's happened
to enough people that there's bugs filed, and VDH's help page has documentation
on how to fix the issue.
I suggest a documentation update -- the "failure to connect to native host"
links to this page https://community.kde.org/Plasma/Browser_Integration . I
suggest adding info like they have here (Video Downloadhelper has the same
issue, and they have a working fix)
https://github.com/aclap-dev/video-downloadhelper/wiki/CoApp-not-recognized
In short, you run
sudo apt-get install -y flatpak
flatpak permission-set webextensions org.kde.plasma.browser_integration
snap.firefox yes
(Why snap has this problem... why the snap developers, or the developers of the
snap firefox package, haven't figured out the root cause to make it ask for
permission like it's supposed to in these cases where it doesn't... and why
snap doesn't have a tool to manage these permissions, but flatpak not only does
have a tool but has one that also works with snap permissions? I don't know,
just imagine I have a giant rant about Snap here.)
Of course this apt-get command is not distro-neutral, but as far as I know only
Ubuntu (and some Ubuntu-derived distros that also use apt-get) have a
snap-based version of Firefox anyway.
Thanks!
