DWM - High CPU utilization when running multiple instances of firefox

Hello everyone

As title says, when I open multiple firefox instances the system start to slow and I can see from htop a high cpu utilization. Closing all the extra firefox but one restore the system to normality.

A thing that maybe is relevant, I'm starting dwm from SDDM because normally I use Archlinux + KDE Plasma, while this is the environment I was testing:

    dwm (patches: attachaside, autostart, gridmode, hide_vacant_tags, restartsig, statuscmd-signal, swallow)

    dmenu (no patches)

    st (patches: alpha, font2, scrollback, scrollback-mouse, scrollback-mouse-altscreen, vertcenter, xresources)

I tried AwesomeWM and the problem does not show up and using Brave browser in DWM is ok, so in my case the problem is the particular combination FF + DWM.


I looked through various forums if it was a common problem but I couldn't find anything similar. How can I proceed to solve the issue?
