debian stable - v11 - bullseye - firefox esr performance improvement on old hardware
For some websites, the default settings in firefox esr on my old hardware, seems to make the site slow to load, and have "top" indicate unexpectedly high system load (4+), even though the website was mostly text (news google com).
=> Edit => Settings => Fonts and Colors => Advanced (is a button) => UN-CHECK "allow pages to choose their own fonts, instead of your selections above."
I discovered if you un-check the setting, under Advanced, for fonts, of "allow sites to override font settings", the pages are faster to load, and the system load is noticeably reduced.
