If you are on localized page and click the big "mozilla support" logo in the header, homepage in English is loaded, ignoring any previous language selection.
Thanks for reporting this, Tomas. If we could change the click target of the big logo in the header, what would you like it to be? Alternatively, if we disabled the ability to click the logo as a link, do you think the breadcrumb links (blue ones under the logo) would be enough for users to find their way to the main page?
It would be enough if https://support.mozilla.org remebers the previous language choise from the language picker on the top. Than the link can just lead to the https://support.mozilla.org. Tikl then, it should lead to https://support.mozilla.org/current_lang_code. Or it can be partially solved by fixing bug 1337553
I tweaked a small bit in the component and it seems to be working OK and as you requested on stage (https://support-stage.allizom.org/). We'll have this pushed later this week to prod. Let's see if that solves the issue. Thanks for following up!
I have tried for Czech (without logging in) and the link is always the same as the current page opened. Just check https://support-stage.allizom.org/t5/Firefox/ct-p/Firefox-cs or https://support-stage.allizom.org/t5/Privacy-and-security-settings/bd-p/Privacy-Security-cs.
