Review for the Firefox version of YT crawler, July 2026.
Although Firefox says the extension is installed, it does not run. Seeing as it is 4 years old this is maybe expected.
I noted another review said it only saved 20 comments which is useless for me. The video I wanted to save comments for has over 3000 of them - exactly why I need to download and view them offline so every time I restart reading I can be sure of where I was up to without endless scrolling (and youtube re-organising behind my back)!!

Seems to not be able to handle all comments, contrary to the description text. Seems to only handle the top level ones. Freezes up on channels with a significant number of comments. Seems to not be able to handle extra replies. i can't use this for what i need, which is all comments, replies, and expanded comments that require the 'see more' to be clicked. Excellent Otherwise. Great for small number of comments.

Nice

Thanks.

Saved the comments, nice!

Nice extension overall.

OK
