v15: security fixes
This release fixes the following issues, reported by @CyrilleB79 and fixed by them. We would like to thank @CyrilleB79 for responsibly reporting security issues in private, and helping fix them:
- addon can no longer be updated on secure screens
- dictionaries can no longer be updated on secure screens
- copy addon helper can no longer be run on secure screens
We recommend updating to this version as quickly as possible. There are currently no known exploits of these issues at the current time, and exploiting them would require physical access to an admin screen on your computer. Never the less, updating is recommended for all users.
