Restrict the scrollbar hack to the keycode for "spacebar",
since the bug only occurs in Firefox with spacebar.
Keyboard navigation is only activated for the spacebar if
the currently focused element is not a button.
These lines were introduced in 612f59aa10
when the only shortcuts were +/-/=/0 (to change zoom level).
Back then, when the input fields were focused, using these keys would
add these unwanted characters to the input field and change the zoom
level of the viewer. Having both operations at the same time was an
undesired event, so a check was inserted, to ignore shortcuts when
the toolbar is focused.
The #toolbar element doesn't exist any more, so these lines are obsolete.
The PDF Viewer will always be rendered directly from the extension,
so checking "origin == chrome-extension:/.." is not needed any more.
( since edd4bae903 )
This method captures all application/pdf streams, loads the viewer
and passes the stream to the PDF.js viewer.
This commit shows a proof of concept using the chrome.streamsPrivate API.
Advantages of new method:
- Access to the response body of the original request, thus fewer
network requests.
- PDFs from non-GET requests (e.g. POST) are now supported.
- FTP files are also supported.
Possible improvements:
- Use declared content scripts instead of dynamic chrome.tabs.executeScript.
This allows the extension to render the viewer in frames when the
extension is disallowed to run executeScript for the top URL.
- Use chrome.declarativeWebRequest instead of webRequest, and replace
background page with event page (don't forget to profile the
difference & will the background/event page still work as intended?).
