Bug Description

The new firefox snap in jammy is unable to open weblink included in pdf (for example using evince).

Steps to reproduce:

1. clean install of jammy
2. download the following pdf:
https://packaging.ubuntu.com/ubuntu-packaging-guide.pdf
3. open this pdf with evince
4. go to page 6 and click on the link "The new account help page".
5. the link is not opened in firefox

The same behavior occurs for any weblink in any pdf. In Ubuntu 20.04 this is working fine.
The chromium snap has the same problem.
This seems to be a problem with AppArmor and snap.
