** Bug watch added: Mozilla Bugzilla #1956549 https://bugzilla.mozilla.org/show_bug.cgi?id=1956549 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/2100945 Title: MozillaTeam snapfree package refuses to work with apport Status in firefox package in Ubuntu: Invalid Bug description: I installed firefox via `sudo add-apt-repository ppa:mozillateam/ppa` I encountered some problems with it (`dmesg` is filled with `[ 9149.120185] audit: type=1400 audit(1741179598.366:5202): apparmor="DENIED" operation="open" class="file" profile="firefox" name="/proc/12151/oom_score_adj" pid=6192 comm="firefox" requested_mask="w" denied_mask="w" fsuid=1000 ouid=1000` and similar) I tried to follow https://wiki.ubuntu.com/MozillaTeam/Bugs#Use_Apport but it failed ``` *** Problem in firefox The problem cannot be reported: This does not seem to be an official Ubuntu package. Please retry after updating the indexes of available packages, if that does not work then remove related third party packages and try again. Press any key to continue... ``` How should I report problems in firefox from `ppa:mozillateam/ppa` Or maybe MozillaTeam in https://wiki.ubuntu.com/MozillaTeam/Bugs and mozillateam in `ppa:mozillateam/ppa` are different things?
