i dont know why but my firefox is not loading pages fully , lot of breakages or not loading most of the stuff while other browsers are ok , it says its up to date , i restarted it and restarted pc
i also had the problem with NSIS but it happened since some days earlier so maybe not connected with this problem
NSIS Error error writing temporary file make sure your temp folder is valid
Its a fork of Firefox with a different user.js
No it is just a user.js which you apply on regular firefox or firefox-based browsers
