If you live in non-English speaking country, it makes real sense. The point is to have english as default input language for new tab and save used language for each tab. IE8 provides this feature out of the box. There is an addon for Firefox that does this, but:
1) it doesn't work in 4.0
2) it is an essential feature that might be availiable in Firefox itself.

Examples of usefulness:
1. You are searching something with Google in your native language and want to open some site -> you have to change the language, because URLs are in English. There would be no harm from a feature I'm requesting.
2. You always use english for about:config or any English forum and always use russian for some Russian sites. Saving input languages would help you save your neurons.

Thanks sencerely.

Reproducible: Always

Steps to Reproduce:
Change a tab or open a new tab
Actual Results:  
System input language stays the same, it is saved for the whole Firefox without regarding to the content

Expected Results:  
System input language should be stored for every tab separately (like in IE) and English should be used for new tabs as URLs are English (at least, for now)

This feature could be switchable in Options or about:config.

i confirm that issue is present even on 42.
firefox needs to remember each input language set on opened tabs.
and on newly opened tabs it needs to revert to the default/top language set on the windows settings.
it must work in a similar way to IE.

input system issue rather than I18N. intl.keyboard.per_window_layout (on Windows) for per window, but no options for per tab.

Today (Sep 25, 2020), I found that even silly Internet Explorer 11 added the feature from current request.
Honestly, I am very unpleasantly surprised that the FireFix browser is not going to do this.
