policeman

Request filters: These add-ons filter requests to 3rd party hosts, effectively blocking everything (if set to default to deny all). Most sites, other than web applications or ecommerce, only need to connect to at most a single remote host to pull down their CSS files; the next most common requirement is Google Hosted Libraries. * RequestPolicy: No longer developed, but still works for me https://addons.mozilla.org/en-US/firefox/addon/requestpolicy... * RequestPolicy Continued https://requestpolicycontinued.github.io/ * Policeman: Haven't tried it, but AFAIK it also filters by data type (e.g., allow media requests from x.com to y.com, but not scripts) https://github.com/futpib/policeman

Check out Policeman: https://github.com/futpib/policeman It's similar to uMatrix and is under very active development.

I have always loved requestpolicy but for some reason something about RPContinued makes me nervous. Policeman would be a great alternative if Sync worked[^1]. I cant use policeman if it means I have to jump through the same hoops on every firefox installation in order to get things set up. [^1]: https://github.com/futpib/policeman/issues/28 Plus issues 92 and 95.

You can use Policeman https://addons.mozilla.org/en-US/firefox/addon/policeman/ Or on Github for a more bleeding-edge version https://github.com/futpib/policeman/releases

Together with umatrix (https://github.com/gorhill/uMatrix/) are the best chrome extensions Since I went back to firefox those are the only extensions I really miss, there is policeman (https://github.com/futpib/policeman/) but it's not as good as them yet To whoever develop extensions, please don't focus only on chrome, firefox during the last months has become must better that it was before, if developers only consider chrome, people will eventually migrate to it and firefox will die. Even though chromium is open it won't be good for the ecosystem
