I do second this too (and I just voted for it). But the feature request should have a wider scope: one could also be able to switfly change the language in browser extensions.
(I’m a new user… and being unable to change the language is the biggest drawback in my daily use of BW).
New Bitwarden user. Recent open source lover too. Seeing my native language in an app like Bitwarden makes me annoyed to the point, that I consider changing my system language only for this reason. For some reason it is not the only time I have seen open source software follow system language only.
To be clear, there is a setting available in the Desktop app and in the Web Vault app to change the language.
Furthermore, in the mobile app and browser extension, the language will match the language setting for the browser, not the system language. Instructions are available for changing the browser language in the Chrome-based browsers and in Firefox.
P.S. I will change the tags of this feature request to restrict the scope to browser extensions and mobile.
