Alternative question:
Is worldwide Google search (NCR) still available?
If Google is used from an internet segment with excessive SEO (for example, during travel), English queries will often be mixed with irrelevant local non-English results. VPN for different country can partially solve this, but it seems many years ago a worldwide version of Google existed (named No Country Redirect or NCR) which provided the best results.
This question is mostly about Firefox, but if clean solution exists only under Chrome – it will be accepted.
Focus is on minimal history/tracking browser settings (possibly combined with removal of cookies/terms pop-ups using cut extensions). Chrome seems to have this mode only with auto clean on restart extension or full incognito.
Just in case - the question is about removing local spam from search results, and it is misleading to focus on language here: you can set English language in Google settingsettings, which will give pseudo-English results still spammed with local SEO.
Is Google NCR currently available and how to set it up?
