Works as advertised but I wish I could whitelist some channels.

I'm using it with YouTube Anti Translate(I cannot add url, so replace spaces with dots: addons mozilla org/en-US/firefox/addon/youtube-anti-translate/) and ublock and it freezes me the youtube. I tried it on different browsers. If I disable any of these 3, youtube works again - still if I disable the Anti Translate I have the best results, because if I keep this one with any other I have high CPU usage but hopefully you can find the issue.

Mostly works as intended. Some videos are unaffected by the thumbnail change.
An option to remove emojis from video titles would be awesome

It's a good idea but the thumbnail quality is awful

better then dearrow bs

I love this, but it's not working on all videos on my home. ~1/20 are completely unaffected.

It try hard to show face instead of actual content

Most of the time this addon does not work. It doesn't recognise abbreviations or model names of products, so it makes the titles harder to read. DeArrow is much more effective.

It does the job and efficiently.
As soon as it's on I compared the result with a private tab (didn't allow the extension on it) and it's obvious the difference it makes in my ability to focus instead of having clickbait bs on my screen.
This is immediately going on all my devices, alongside Ublock and Sponsorblock.

Exactly what I was looking for

Works nicely. One suggestion - remove exclamation marks from titles.

you are genius
