convert hacking device to my console

Here is one example: http://iopscience.iop.org/journal/0031-9155/page/PMB_webinars

Click "Invite", and there's a couple of text boxes. Clicking backspace in one of those will navigate back (if possible), or otherwise simply ignore the backspace key.

Looks same as  Issue 639645  hence merging into that. Please un-merge if this is different.

I've fixed the Flash issue (fix in review), but can't get the same problem to show up for the PDF control. Re-splitting the two bugs for now, so I can continue investigating the other one.

The Flash fixes landed as

patchset #5 (id:80001), committed manually as
6cfc8a0b8ad0e6d5485912816371ac07eced8259 (presubmit successful).

They haven't yet been put into the Web Store. They'll be in v2.0.

Apologies for how long this is taking to get to the Web Store. It's part of a larger batch of features, including a blacklist (individual pages you don't want the extension to go back from), a button up by the omnibox to add a page to that blacklist, and a whitelist (in case there's a Flash app where you *do* want to go back). Making a usable UI is always harder than just making the feature work. ;)
