Can't resize columns in 'network' tab Step, Step Into, Resume.. use different function keys than I'm used to on Linux. Edit + Resend doesn't work for me on Linux. It works on Windows for me. Copying headers doesn't work well for me on Linux. I have to click 'Raw Headers' to copy a header. Works fine on Windows. Chrome is still faster than Firefox. I prefer chrome and Edge's download monitor. I prefer Firefox's proxy controls.
