This used to be a good addon and, in theory, it still is... but the current decision for how to handle changelog announcements, combined with the visual design of the changelog, makes it too reminiscent of adware.

How so?

Expect it to, without warning, steal you away from whatever tab you're looking at, to present you with a huge, ad-like changelog.

This is the kind of behaviour that's had family members calling me, afraid they've been hacked and, as a more tech-savvy user who uses multiple devices and Firefox profiles, it presents me with repeated annoyances I can't opt out of.

I've been using this extension since almost day one but now, I am seriously considering uninstalling it and taking my chances.
