need way to disable all extensions and automatic page reloads before logging on to chromebook

Project Member Reported by semenzato@chromium.org, Mar 10 2017

Issue description

(or if this already exists, it needs to be easier to find because I could not)

I have a Chromebook customer with persistent malware, probably an extension which takes over keyboard and screen and asks the customer to call "Microsoft", see photo.  This makes the chromebook unusable.  Logging out and back on does not fix the problem.  Logging out with long power button press also doesn't help.  (Although that may have been a normal shutdown... we didn't try reload-power.)

To the best of my knowledge, control-W and other keyboard shortcuts do nothing for this customer.  Also, the customer does not have easy access to another computer running Chrome.

I understand that we can ask the customer to remove his account (or powerwash the machine), log on again, and then quickly turn sync off before the extension is reloaded, but I don't think that this solution is acceptable in general.  It's racy, and the customer can be slow.

Being able to log on without reloading pages, and with all extensions disabled, may be a saner way of recovering.  I don't have suggestions for the UX/UI for this.

Essentially we need an extensions disabled safe-mode.

Would our safe mode covers this case?

Yep.

You couldn't click on "prevent this web page from creating additional dialogs" and then go to chrome:extensions?
#4 yes indeed we did not try that.  Sorry about it.  I was debugging via a third party and the initial "screenshot" did not include the full window, then the customer had to leave.

In fact I also didn't think that an extension could intercept control-W (can it?).  But of course that modal window does... it has to.

Now I don't even think this was an extension.  Probably just an evil site.

The "safe mode" in #2 will be helpful to people that get confused.

Thank you all!
