I installed Brave on Crostini on a Chromebook. When I then add the Bitwarden extension and click on the Bitwarden icon in the toolbar, it displays the menu like this:
instead of what I expect it to look more like this
Brave 1.83.120
Bitwarden 2025.10.0
ChromeOS 140.0.7339.242
I do not see a fix or workaround at this point. Tried logging in to BW from the BW website. I also then installed Google Translate and that dialogue pops up as expected when the toolbar icon is clicked. Rebooted. None seemed to make a difference. I thought it might be a BW issue but then I confirmed similar behavior with the extension from Duck Duck Go and Privacy.com
