Firefox 53.0.2 with more than one Firefox process! I get one process for every tab now! You have to set it up in about:config for this to happen at least to get one process for every tab.
 
I don't have that, and I have Win 7 w/ Firefox 53.0.2. I have one process for Firefox (5 tabs open), but it's huge...752,844k

What addons do you have installed?

If you don't want to say then are any of them old XUL addons that don't have multiprocess/e10 support?

Check to see if multiprocess is enabled. Type about:support in Firefox address bar. It should say this: Multiprocess Windows 1/1 (Enabled by default)
 
Whoops...it says disabled by addons. But in the addons manager, it says multiprocess is enabled.

plus a couple more. It does say 2 are incompatible with multiprocess.

Sense 2 are incompatible with multiprocess you won't be able to run multiprocess/e10s stable. So it is recommended for you to not do this. Unless you get rid of those 2 addons.

You can force enable multiprocess/e10s but it can make Firefox even slower like that if all your addons are not multiprocess compatible.

Quick question; why are you using 32bit FF?
Click to expand...

Good question! I forgot to address this so thank you for reminding me! Main reason is because Firefox 64 bit was giving me some weird trouble and decided to just stay with the proven 32 bit for now. I don't mind upgrading to 64 bit though if I have to for one reason or another.

That's a perfectly valid reason of course. I'd recommend trying FF52 or newer in the x64 version. The older x64 versions did indeed have a few issues, but they appear mostly fixed now. It really helps if you have plenty of tabs open. You get ASLR protection as a bonus.

What's the multi process tweak (ie. more than two processes)?

https://www.ghacks.net/2016/02/15/change-how-many-processes-multi-process-firefox-uses/

Set it from 1 to 128 if multiprocess/e10s is enabled on your Firefox 53.0.2!

You can always set it lower too. I was told no higher than 4 or 8 wouldn't make a difference but I disagree I like having a process for each tab and I never open more than 128 tabs.
 
With that tweak I get a pretty close result in the multi-tab loading job that I've been pitting FF and Chrome against. Memory usage is pretty similar as well.

Nice. I noticed the same thing! Glad to see it verify!

I don't really care how much memory my browser takes that is why I got 32 GB of ram.
 
I don't get it. I enabled this in about:config, but I don't see any enable multiprocess option anywhere.

Apparently addons are blocking it, according to about:support. How do I know which one(s) is the problem?
