I suspect this doesn't work because you need to use new reddit. Doesn't work on 'old' reddit.

works exactly as intended, a really helpful extension for me. thanks for not including any kind of ads in this

working just fine on firefox nightly, so just ignore that 1 star. thanks!

(and i have some overly-aggressive ublock filters that sometimes 'over-block' stuff, but it's not blocking this).

Doesn't work. The "Reveal activity" button doesn't appear.

Flawless and works great!
