As written, with Ff 89 beta for Android, the setting "dom.ipc.processCount" resets itself to 1 every restart.

https://github.com/mozilla-mobile/fenix/issues/19385

Can someone please explain me why? It felt much faster before with a setting of 4 or 6 and still feels faster when I set it in about:config for the time not doing a restart...what is going on here?

And why is such a change not being communicated to the community somehow and I/we have to find this out by ourself?

Greets and with best regards, Michael

Hi

This is a process that is managed in GeckoView and is not configurable through about:config.

Ok, and why am I being able to set "dom.ipc.processCount" in Ff 88's prefs.js or about:config successful to 6, resulting in up to 6 webcontent-processes shown in "about:support" - and not in 89 anymore?

Or: why uses Ff 89 less WebContent-processes (and feels slower...) than Ff 88?

Because this commit has landed on 89: https://phabricator.services.mozilla.com/D109798 . It resets the setting "dom.ipc.processCount" to 1 (in 90 to 2) every restart.

I believe that everything is explained right now.

This parameter is locked to 1 after a certain update. You can customize the size of the value, but the value will be reset to 1 after closing the software and opening the software again. Not only this value is locked, but many other parameters are locked, such as "browser.safebrowsing.malware.enabled" and "browser.safebrowsing.phishing.enabled". These values ​​can be unlocked by recompiling.
