Assert button doesn't appear on Firefox

Hi,

The assert button doesn't appear on Firefox, I verified it appears on Chromium

Any chance you could share a quick screen recording of it not working? I took a quick check and it seems to be working okay for me right now.

FF Version: 106.0.2, DeploySentinel Addon Version: 0.6.1

Just a note, the assertion popout will only show up once you've highlighted some text first before right clicking.
