One of the evergreen simple browser extensions I keep going back to, and blocking annoying stuff all over the internets! If we could have rule sharing it would be even better!
Good!!
Super dodatek i przynajmniej działa w porównaniu do małpy.
Fantastic extension that I use almost daily!
Simple to use and does the job well.
Pretty much exactly what I was looking for: A lightweight method to modify the behavior and look of websites. Lots of features I do not yet need, but which may come in handy. Things that could be improved: – Export not as JSON but zip which contains separate files for JS, CSS, options. That way it can be unpacked into a repository folder and managed with git. – Import from a zip. – Alternatively, backup not to Google cloud, but to GH repository or gist, including commits. – Make documentation easily accessible from editor. – Document editor shortcuts. Also, how about making it open source?
Perfecto para lo que necesitaba.
Ultra Mega Super Great job! This extension works perfectly — simple, powerful, and incredibly useful. Exactly what I needed to customize pages the way I want. Huge thanks to the developer!
Love this extension. It's simple and it deliver exactly what it tells. Would be great to have a repository of other people's published rules for typical things like "Remove cookies banner" or "Redirect Instagram to For You and remove all algorithmic feeds". Also, it would be great to have the rules synchronized accross devices automatically rather than having to click on Upload JSON/Download JSON.
Вообще перестал работать.
