[tbb-dev] Tor Browser mistakes clearnet web addresses for localhost or Hidden services

[Richard]

Hello, I want to report this bug.

My OS - Kicksecure, based on Debian. https://www.kicksecure.com/
Tor Browser version - 12.0.1
Security level - safer
Steps for reproduction - copy and paste any websearch request to search bar,
click on Startpage icon in the search bar menu, then https://localhost/ appears
in the search bar as if Tor Browser tried to contact localhost instead of
startpage. The issue may not be readily reproduced 100% of all the times, it
comes up very rarely when I do some web search.  This all can happen if I use
either a custom search engine for a single websearch request or with default
search engine. This is metager onion link for me. Note that Tor Browser may
sometimes mistake clearnet link for a hidden service instead of localhost. In
such case it would only display a standard built-in page that says hidden
service with such name is not found.
