(Keywords: blocked-ux, perf)

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:68.0) Gecko/20100101 Firefox/68.0

Steps to reproduce:

Set up firefox Startup to restore the previous session
Open many tabs on many windows and restart firefox
Close and start firefox again

Actual results:

Every tab starts loading, making startup slow.

  • Too many Compute/Network resources are needed.
  • Some sites, like hacker news, don't render properly because of DoS protection.

Expected results:

Tabs use cached data and really start loading when they are focused.
Maybe all the tabs from the active window should start loading.
