Replacing words not working

Anonyme il y a 1 an dans Accounts / Browser mis à jour il y a 1 an 2

I can’t seem to replace any words on the browser. I’m using the correct case and everything. It’s just not working and I’ve done it before so I know it should work.

What website are you trying to use/replace content?

I believe it was TMZ and/or IMDB
