Firefox and Thunderbird can't read /usr to add apps to handlers file

cn flag

In some recent update I lost all the application handlers in both Firefox and Thunderbird. When I search for "other apps" it reports no permission to access /usr. The directory has 755 permissions, however.

What is your Ubuntu version? Are these applications installed as snap? Check if they appear in the output of `snap list`. If it are snaps, indeed they cannot access /usr.

It's 21.10. Firefox is installed via snap. Thunderbird behaves that way whether the Ubuntu version via apt or a direct binary download. Firefox only started behaving this way recently.

Please add all info that can be relevant to the question: use "edit".

I have the same issue with Firefox in Ubuntu 21.10 (can't really read usr/ even though the permissions are fine). As stated in the comments, the problem is the snap. So remove the Firefox snap and re-install it via apt.

sudo snap remove firefox
sudo apt install firefox

(It remains a mystery to me why Ubuntu has Firefox snap by default, since it is flawed)

21.10 has snap as default? I have 20.04 and it has both Firefox and Thunderbird as regular deb packages.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
