--firefox.profileTemplate should take precedence on firefoxPreferences.js

[tarekziade]

When setting up preferences via the profile template, browsertime overrides them with values from firefoxPreferences.js when calling geckodriver. The only solution is to use --firefox.preference but that defeats the purpose of --firefox.profileTemplate

We should make sure preferences set in the templates are not overriden by firefoxPreferences.js defaults

Hi @tarekziade I've never used the profileTemplate, do you have an example of a template file? Is it correct that if you set a profile template, defaultFirefoxPreferences should't be set at all?

[tarekziade]

a template directory is basically a firefox profile that is passed to the browser via geckodriver.
In my case it contains user.js and prefs.js

I think the right behavior would be to selectively removing prefs from https://github.com/sitespeedio/browsertime/blob/main/lib/firefox/settings/firefoxPreferences.js that are set through the profileTemplate

[soulgalore]

I see cool. I think I can fix that if you share a simple profile for your use case with the file? It would be great to add a test case where we have profile, I don't think we have that today.
