There's still nothing about the telemetry in the browser extension? I couldn't find any mention about it in the "Help us improve Proton apps" or from the privacy policy page. The privacy policy mentions "It details the data processing activities specifically related to the creation and activity of your Proton Account when you use Proton Pass." though, but it's a bit unclear.

When looking at the extension's source code, telemetry data is anonymous, but it's always sent to the remote endpoint, and the only way to disable it is from your Proton account, not the extension itself.

The telemetry option is shared between all products and can be accessed from account pages for each product, for https://account.proton.me/u/0/drive/security for Drive, https://account.proton.me/u/0/pass/security for Pass, etc.
