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.

This works great with my desktop, but it does not work at all for mobile. I installed this app so that I would not have to worry about emojis (especially a certain kind of emoji anymore). Much, if not most of my YouTube experience is through mobile. So as much as I appreciate how effective this is on my PC, I cannot give it more than 3 stars until I can access YouTube mobile through Firefox or there is an app that can eliminate emojis on the YouTube app.

I like what it does for thumbnails, but I wish there was a way to disable what it does to titles - it removes ALL caps from titles so they look weird now and unprofessional. Each word of a title should be capitalized, this add-on makes all except the first word lowercase.
