In case this was discussed before feel free to disregard the comments, I just thought I'd leave here what I felt could be the options when looking into the differences:

(Also wondering, how to differentiate UK vs. US titles a slightly more, like using "from" vs. "by" in them, but leaving that for a reviewer better equipped for language tweaks;D)

I agree with Jan's comments that we should use by Mozilla to avoid too much Firefox repetition

I had some notes originally in #385 — with perhaps a little more intricate disambiguation for some of the key pages, also with ideas about moving the prefix+suffix 3-section titles in some places to just 2-section content when customizing. Also /browsers/mobile does not appear to use the same way of separating the different English variations to help them not get duped against each other in search results. Ah I see mobile/index does not disambiguate but then deeper e.g. mobile/ios does so it's probably fine at that level.

Not sure if there's e.g. meta content already available for what should end up in the CMS versions of the pages, to use that as an inspiration for updates to the static templates as well?
