#16364 new defect

Add an option to resize the browser window to the "safe default"

I just played with my browser window, resized it, then set it to the maximum. Then a yellow line appeared, notifying me that this was an unsafe thing to do. The only option was "OK" to acknowledge the warning.

Please add an option to resize the browser window to the initial size (when I launch the browser it is always set to some default that I assume is safer due to mass usage). If possible in the menus of Firefox or whatever is behind that Onion icon and maybe also in that warning bar.

Well, that's what your Resist Fingerprinting checkbox should do when it becomes checked (from unchecked).
As there is no such warning for resizing, maximization warning could be a special way to restore the size.

Minimization has no effect.

Another consideration: accidental resizing via window border grab bars.

One suggestion is not to allow accidental window resizing at all, via dragging the window borders.
Because it's very easy to accidentally move the borders, prevent the action - at least momentarily. Popup a warning - "Do you really want to resize TBB's window? This is not recommended!"

Unless they don't know the implications of changing TBB's borders or have low anonymity requirements, probably few users intentionally drag TBB borders.

At least in Linux - maybe more in some desktops, it's incredibly easy to move the window border when clicking the scrollbar thumb, if the cursor is slightly moving. No easy way to reset window to original spoofed size.

In Linux - Cinnamon, you don't have to straddle the Fx border - just be near it when grabbing the scrollbar thumb. Most users don't completely stop the cursor before clicking the scrollbar.
The new, narrower scrollbars make the problem worse.
