Chrome Extension Modifying Address Bar Visibility

[Amelia Rave]

Hi all,

I'm wondering if anyone knows about the accessibility to chrome's address bar and scroll bar. I would like to create an extension that removes the address and scroll bar for a non-fullscreen window. Does anyone know if this is possible? I have not seen a way to modify the address bar before. Thanks in advance!

For security reasons, I would not expect that to be possible.

Thanks for your response Bayden. Can you elaborate on the security risks of this? I'm thinking of functionality like some fullscreen modes where toolbars are visible only on mouse-over, but the window is not fullscreen.

Eric is referring to extension scope for modifications. Essentially, when building an extension, one must consider "feature availability" with "can this be justified, at the risk of someone potentially misusing it" for regular users. The address bar is one of these components which are immutable for modifications, aside from colour and textile modifications to icons by design.

Specifically, the fullscreen API within Chrome is not exposed to extensions as without extensive restrictions, it would possible to break the browser if someone wished to because of how low level the API is internally within the browser (and the extension is hooked in). 

Hope this helps.

Cheers,

Removing the scroll bar can be done by setting the style "overflow: hidden".

Removing the address bar is sort of possible by creating a popup window.

Chrome has two types of popup windows:

1. Popup windows created by regular webpages. These do have an address bar.

2. Popup windows created by extensions, These do not have an address bar.

Those are your options. I'm not aware of any other way of not having an address bar.

This is a get around solution, however was not how i interpreted the question. It seems OP is asking if it is possible to modify active window sessions (for extensions to inject into), other than make a new window. Hypothetically it could be done by mirroring the URL into a new popup bar, but also falls under the same point noted in the first sentence.
