fb purity has been updated for Chrome and Edge and IE. the developer is waiting for Firefox to do the update. I use it and like it but it does not do all the things it does on other browsers because it is not updated. I think the developer of fb purity is waiting for firebox to update or give him the code or whatever you have to do to make it work. I like the extension but like i said It does not do what it does and when it removes on the other browsers .I like and have used Firefox for years and do not want to use any other browser So I am asking please allow this extension to update on Firefox. Thanks
