Details

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:76.0) Gecko/20100101 Firefox/76.0

Steps to reproduce:

  • Typed in Email in gmail
  • Noticed input delay and how my notebook's fans (old Corei5 540M laptop) spinned up

Actual results:

Expected results:

  • Firefox should behave like Google Chrome.
    There one process consumes 70% cpu (so there is most likely a lot of scripting going on), but at least I didn't have the impression the browser can not keep up with the frequency of my keystrokes while typing.
