</p><p>Maybe someone can answer: Why was the multiple application introduced in the first place when it is detrimental to users computers and why has the practise not been eradicated? I'm getting very cynical!

<p>Where do I find browser.tabs.remote.autostart to make the changes?

</p><p>The number of Firefox processes active is actually ONE. CPU usage is nominal. Mem usage is nominal. See screen print where CPU usage is 11%.
No keyboard lag/freeeze in email (or typing this post) whatsoever!! No hangs, delays when moving around email folders. No hangs/lags when opening up new tabs from within another tab (eg. clicking on a CNN link).
Hope this change makes Firefox more stable and my laptop won't crash like it did before.

It seems that the Process Content Limit setting was just a placebo to make users think that they actually had some control.
I've been going back-n-forth with a contributor for weeks w/o any results. Like Felis-Lict, I've reduced the process Limit down to 1. However, did nothing to the number of actual process running and only shot cpu usage up to 90+% and laptop crashes have been more frequent. Screen print attached showing 5 process running when the setting was at 1.
My work-around has been to use MS Edge. It runs with almost a dozen processes but sucks up far less cpu &amp; mem, doesn't freeze up the system or crash my laptop.
I was about to post yet another complaint when I came across this post. I wasn't told about the browser.tabs.remote.autostart trick. I'll give that a try and post an update later.
</p><p>Da**m..WTF!!! Sorry about the outburst. Against my better judgement, I was using Firefox to make this post and it crashed my laptop before I finished. Took forever to recover and to make sure nothing else was crapped out or lost.
