[FEATURE REQUEST] Browser Extension version checks

### Please confirm these before moving forward

- [X] I have searched for my feature proposal and have not found a work-in-progress/duplicate/resolved/discarded issue.

### Describe the new feature

To be clear, the feature being suggested here is not to allow installation/updates to existing extensions.

However, it would be great to be able to have extensions for browsers checked to see if any are out-of-date, when X browser hasn't been launched in a while (extensions don't update unless X browser gets launched to check for updates).

\* X = Chrome, Edge, Firefox, etc.
### Describe how this new feature could help users.

While extensions not being updated don't pose an initial threat, it's nice to have a single place to see if everything is up-to-date (especially if X browser hasn't been launched in a long time to update the extensions on it)

If you think this is a good idea, I can work on a PoC script that grabs extension data only for installed browsers (I've been working on a script already that audits extensions for all browsers, installed or portable, so it's not much work for me to do).
