Last localization to spanish is not totally good. It uses a regional and not generic terms or words in some texts, I.e. "Doná" or "Explorá" instead of "Dona" or "Explora".

"503 Service Unavailable" on Reddit for weeks or months. They're blocking Tor. Twitter sometimes blocks Tor all of a sudden. "Something went wrong" YouTube started doing less sudden blocking redirects to and more captchas. Teddit, Nitter, Invidious, Bibliogram... Front ends like those are sometimes the only way to read or watch them. To reach Reddit, it **is the only way** anymore. **Can we please have Tor Browser come with Privacy Redirect or something like it??**
