Reproducible on the latest Nightly (BuildID: 20140408030205) Mozilla/5.0 (Windows NT 6.1; WOW64; rv:31.0) Gecko/20100101 Firefox/31.0 Reproducible on the latest Beta (BuildID: 20140407135746) Mozilla/5.0 (Windows NT 6.1; WOW64; rv:29.0) Gecko/20130205 Firefox/29.0 Reproducible on the latest Aurora (BuildID: 20140409004002) Mozilla/5.0 (Windows NT 6.1; WOW64; rv:30.0) Gecko/20130205 Firefox/30.0 Steps to reproduce: 1. Open about:preferences. 2. Observe the name of the “about:preferences” tab. Actual results: The name of the “about:preferences” tab is inconsistent across platforms: - on Windows, it is "Options" - on Ubuntu, it is "Nightly Preferences" Expected results: The name of the "about:preferences" tab is consistent across platforms. Notes: This issue is not a regression.

It's expected behavior that the Options/Preferences label is used according to platform conventions.

What I meant is that on Ubuntu we have "Nightly Preferences" and on Windows we have only "Options", without the word Nightly. I think that we should have "Nightly Preferences"/"Nightly Options" or "Preferences"/"Options".

I think it's intentional (and in line with platform conventions) to say "<Appname> Preferences", but only "Options" with no app name. If that's not the case then we can re-open.
