Most of these redirects work great, but some don't work for me (404). Thankfully, the redirects I care about seem to work fine, except for:

1) IMDB. It always continues to the regular imdb site even with the redirect enabled/saved.
2) Translate Google: If the regular Google redirect is enabled at same time, then translate google page goes there (eg. searx). So I have to pick one or the other.

Please look into this, as this addon is great.

EDIT: I'm not sure of limitations but would it be possible to let the users define their own redirects?

I hope it will get way more website support in the future

It's a great way to preserve what privacy you have on the internet, however you do rely on pre-defined URLs that may not exist or work anymore, and you can't fill in your own.

For instance, none of the alternative links for Reddit work at the time of me writing this review. And if you're still on old.reddit this extension doesn't redirect you to any of the alternatives, which turns out to be a blessing is disguise in this case, as none of the alternatives work.

But still, it's better than hand-writing the URLs every time.

I love the extension. However, there is one issue that is big to me. Which makes me reluctant to use it. SponsorBlock and Return YouTube Dislike don't work with this on. There is a chance that this extension blocks other extensions too, and not just for YouTube. For now, I will keep the extension, but refrain from use until a remedy is found. To me, it is just a non-negotiable.
