hi :) you have to enabled it first. Before it starts measuring. And it might needs a fix. (A future version could also analyze whats in browsing history, but that doesn't include duration / will have to guess)

What about joining us on Github? (over 170 people already contributed)

(4 stars is not, helping, reducing the average)
thanks

hi, agree, have written both of that in our to-do lists already long ago. And you could go there to vote for it.

( "so far.. but it'll be better if you made 2 options" many people said such that and it is unaware(/ignorant) of the situation. /Better phrase: "For the wish-list:" )
thanks

hi, there is no "good but i wish" in feedback ratings. If you are ratings below 5 stars, then you are voting against the project.

the feature just received an update. (please differ outdated feature vs actual freezing/ or cpu load) . You shouldn't be surprised when one in 200 features ever needs an update, but be surprised how our development team of 0 people keeps up with Youtube's changed like Sisyphus most of the time. (There might be guarantees for fast updated in future, if we get any funding.)

hi! this feature specifically doesn't work yet with Firefox only. https://github.com/code-charity/youtube/issues/2310, however, since Firefox featured us, now all known Firefox bug can be considered urgent. Did you possibly forget using the feature to hide recommend videos? Please consider it is more likely that there was no need to reinstall. We are one of the biggest projects among the browser extensions already. Over 170 People have helped. Still it is common, that some issues stay for years. You can make a difference. 1000 of steps have been done and 100 are currently on the to-do Lists. We prioritize.

Thank you! We would love to know all issues and read all your wishes on GitHub to sort them in our to-do lists.
