User reviews
I've been using this extension for years. It has worked great most of the time. When it hasn't worked, it's simply because the site blocked the script (not an issue with the extension). Most of the bad reviews are due to user being too picky with the UI, user's skill issues or people not understanding that some sites block these kinds of scripts.

Works for me. Good one.
by Eugene Stupak, 2024-08-20

Works beautifully. Much easier for a novice than TamperMonkey. One issue that does come up is that I can see no way to determine which code runs first. I have resorted to placing all my functions in one file, but that is less convenient. Also, worth mentioning there are sometimes syncing issues, meaning that code I write on one device doesn't sync with the extension on another device even though Chrome syncing is working properly.
