Hello Firefox community, As I realized some time ago, Firefox makes simulatneous requests againgst disk cache and network called "Race Cache With Network" (explained here https://support.mozilla.org/en-US/questions/1267945). In my home country, this has never bothered me as I had an unlimited data plan and therefore was pleased to get fast loading webpages. But now, I moved to a country without unlimited data plans (Ghana, 40GB per month, 120GHC, approx. 20€, approx. 22USD) and I'm thinking about how this feature must be eating up peoples data. Because even if you visited a webpage before and most of data is within your disk cache, Firefox will still issue a network request, resulting in increased network activity and therefore consuming additional data. In my opinion this adversely affects people in emerging countries, as internet is already a pricey good and Firefox is using more data than necessary, just to allow webpages to load fractions of seconds faster. Why is there no UI option (I know it can be turned off, using config key "network.http.rcwn.enabled") for users to turn this feature off more easily in order to save data? Furthermore, this behaviour is not even explained to users, so users might not even know Firefox consumes more data than expected. With best regards, Gabriel
