Hello, I am working as front end developer in a company that have high traffic. in last weeks we want to work on our video upload experience. in this progress i saw that theres no option to limit upload speed or download speed in firefox itself or in developer console. My question is how can i test my codes with firefox (I am showing messages like: Your connection is slow, OR Your upload couldnt finished because of your connnection speed) an add-on a variable in about:config any solution works for me. I dont want to change browser to test this everytime
