got a side project atm, slimming down firefox. removed half the files from the program folder and lots of stuff from the omni.ja files. not sure if it's making a difference yet, still testing. i removed a lot of the devtools components and various telemetry files. still have a basic working element inspector (i only use the first tab to get domains to block in my hosts file) don't use any of the other tabs as i'm not a developer.
