Hey Cristian,

Thanks for reporting. I can't reproduce this issue, so a couple of follow up questions:

1. Is your locale set to Russian?
2. Does https://www.mozilla.org/?utm_source=firefox-browser&utm_medium=firefox-desktop&utm_campaign=about-dialog direct you to the English site? That is what the link is currently set to

In searching with mozregression the settings should have been default. Initial checks had the build and settings to EN.

Did a quick check on macOS 11 and with browser.search.region:

• 86.0 RO --> gives RU page
• 86.0, 88.0a1 (2021-02-22) en-US --> DE page

The link from 2nd question opens up the expected en-US page.

It seems like this might be happening after the URL is sent to mozilla.org
