This is a simple time-saver addon that works exactly as intended and advertized on Firefox desktop (haven't used it on mobile). I love its simplicity—and the easy access menu for saving and printing reports.

Sadly, most of the 1-star reviews seem due to "lack of localhost support" from people that can't be bothered to read the addon description. It requires only a modicum of critical thinking skill to set up free dynamic DNS services for public "localhost" access, and even setting up free LetsEncrypt SSL certificates for secure https access to locally staged development sites is somewhat trivial.

Note to addon dev: perhaps add a bit more about this (localhost use requires x) to the product description, though skimmers are still gonna skim.

Nice i love this

Allows one click lighthouse audits which helps put Firefox on par with native Chrome functionality. Thanks to the team for porting this across and making sitespeed audits even easier to complete!

Приложение с открытым исходным кодом для Firefox. Да еще полезное. Браво.
