I have noticed on certain sites, the newest OS/2 Firefox 38 slows way
down pegging the CPU usage at 100%. I tried the same sites on an
up-to-date Firefox under Win7 and this does not happen.

(1) Question 1: Does anyone know the reason for this?

(2) Question 2: Is there any user adjustments in Firefox 38 that can
be adjusted/changed to help limit this inconvenience?

Thanks in Advance for any input.

Just guessing...

The OS/2 memory management functions of the runtime library (operator
new, operator delete ...) do not scale properly for heavy OOP usage.
I already noticed this in another project.

Probably not if the above assumption proves true.

But limiting JavaScript and using a light ad blocker like µBlock can
reduce the problem sometimes.

Do you mean 31.8.0? 38 is still under development and as far as I know
not actually working on OS/2 yet.

Is plugin-container.exe running at the time of 100% CPU? Do you have
Flash installed?

For Flash, you can go to about:addons and under plugins set Flash to
always ask to be activated.
If plugin-container is actually running, you need to set some
preferences to disable OOP
Marcel's idea of using an adblocker is a good one. I use no-script to
avoid situations such as you describe.

Thanks in Advance for any input.

I mean Forefox 31.8. My Flashplayer is 11.5 r502. It was set at
"Always Activate" so I set it to "Ask to Activate"

Good chance that will help. Flash really needs to be updated for FF
31.8.0 and newer but as it is going away it probably won't be fixed.
Always a good idea to keep the use of our old Flash to a minimum, if
only due to all the vulnerabilities in it.

Use top or such to see if the process using all your CPU is actually plugin-container.exe. Assuming you are using the latest FF, it shouldn't
be a problem.
