Then select different language (in my case English) Actual results: I got redirected to homepage in selected language (https://support.mozilla.org/t5/Mozilla-Support-English/ct-p/Mozilla-EN) Expected results: Same article in selected language should be opened (https://support.mozilla.org/t5/Basic-Browsing/Web-Push-notifications-in-Firefox/ta-p/28744 in this case)
Thanks for reporting this, Tomas. Due to the platform's current limitations, this is an expected behaviour. We will be introducing a component on the article page (in the side bar) that will allow you to switch to other language versions of the viewed article (if they exist and are linked using the English article ID tag). More information on this soon, hopefully. We had the component ready in testing, but string encoding issues made for a bad user experience, so we decided to not launch with it and add it when it's fixed.
Marking as WONTFIX - more details here: https://blog.mozilla.org/sumo/2017/06/28/important-platform-update/
