[Affected versions]:
Nightly 55.0a1

[Affected platforms]:
Ubuntu 16.04 x64

[Steps to reproduce]:
1.Open the System Monitor
2.Launch Firefox with a new profile
3.In the 2 already opened tabs, navigate to 2 websites of your choice
4.Add an integer preference called "dom.ipc.processCount.file" and set the value to 5 in about:config
5.Open 2 local file (PNG, HTML, WebM, .txt, PDF, etc) and check the System monitor processes
6.Open 3 local file (PNG, HTML, WebM, .txt, PDF, etc) and check the System monitor processes


[Expected result]:
5. Two new local content processes should be opened in System monitor.
6. Three more new local content processes should be opened in System monitor.

[Actual result]:
5.Two new local content processes are opened in System monitor.
6.Local files are using the existing content processes opened in step 5.

[Note]
The issue is not reproducible on Windows 10 and Mac OS X 10.11
This seems to be working for me.

Did you open the documents separately (using Ctrl+O for example) in new tabs?

If the pages are related in any way, for example opened using a link from another page, then they will run in the same process as that page.

Hi Bob,

Strangely I can't reproduce this issue either on the latest Nightly version (2017-03-16).
I opened the documents separately by drag and drop from my Desktop and I even used clean profiles.
I'm marking this as Resolved Worksforme and I'll keep an eye on this issue.

Thanks for taking the time to look into it.
