Tor Browser will now warn users when they change the window size. That's great. But the associated button just says “Ok”. I believe it would be better to provide more active buttons that just one that will dismiss the warning.

How about:

  • Unmaximize (when maximized) (or is it too jargony?)
  • Restore common window size (change to the next rounded dimension)
  • I don’t mind sites learning the size of my screen

Having this would also solve #16364.

In the case of Tails, the fact that people might not be used to the way their pointing device and the window manager behaves, leads to many people maximizing their Tor Browser by mistake.


Providing an "Undo" or other mitigation mechanisms in the warning would be particularly relevant for Tails.

What about having two buttons:

[Undo] [Ignore]

Instead of only [Ok]?

I should point out that in training journalists and others in using Tor Browser, almost none notice the current warning when they resize or maximize their window.

Since browser fingerprinting, as far as I know with my admittedly dusty JavaScript knowledge, can happen the moment a browser is resized, something more in-your-face might be more appropriate; e.g. a JS prompt that intercepts the window resize action and prompts the user to either click OK and resize or Cancel and not resize, with a short warning on why resizing can be unsafe.

Interesting, huertanix. I recently did a UX experiment on the Tor Browser and this warning was viewed as one of the positives of the Tor Browser interface by new users, and didn't seem to be missed. Either way, having a way to undo the mistake and set it back to the common dimensions seems like a very useful feature.

For the idea of a JS prompt that is more in-your-face, I like it but it would have to be carefully designed to avoid pop-up fatigue. Maybe only one pop-up per browsing session?

Add magic gitlab keyword.
