Details

(Whiteboard: [photon-preference] [fixed by bug #1406212])

[Affected versions]: 
Beta 55.0b10

[Affected platforms]:
Platforms: Windows 10 x 64, Ubuntu 16.04 and Mac OS X 10.10

[Preconditions]
1. Open Beta with a new profile.
2. Go to about:config and search for "dom.ipc.processCount.web". If this is not 4 repeat steps 1 and 2 until the value of dom.ipc.processCount.web is 4.

[Steps to reproduce]:
1. Open Beta with a new profile.
2. Go to about:preferences#general at Performance section
3. Uncheck the "Use recommended performance settings". -> Content process limit is set to 4(default).
4. Update the content process to 2.
5. Restart browser.

Expected results:
In Preferences page, the Content process limit should be 2 and default value should remain 4(default).

Actual results:
In Preferences page, the Content process limit is 2, but the default value updated to 1(default).


Note:
The problem here is that the labeling for default value is changed from 4(default) to 1(default). The value for the Content process limit remains the one set by the user before browser restart.

This is not an exact dup. Somewhere in the code `dom.ipc.processCount.web` is deleted upon reboot when a manually set `dom.ipc.processCount` value exists.
