Escalating privilege

Useful workarounds and methods to get the power we want in the brave new world of webextensions.

Function in newtab
- chrome_url_overrides
Function in home page
- chrome_settings_overrides
(Downside for both is that we need to reimplement a useful home and newtab page)
Shell and write access to filesystem
- Native_messaging
Hiding firefox chrome
- API proposal for hiding tabstrip (but not nav bar): Bug 1332447
  - :Gijs discusses why nav bar can't be hidden, but I still don't get why whatever happens in fullscreen can't just also happen in windowed mode.
- Hiding with userChrome.css
  - http://kb.mozillazine.org/Chrome_element_names_and_IDs
  - e.g. "#tabbrowser-tabs { visibility: collapse !important; }"
  - requires restart, probably
Commandline thru toolbar API
- Bug 1215064
- As currently envisioned, size is fixed, I think
Commandline thru HTML injection into webcontent
- Dangerous, see Bug 1287590
- Shadow DOM would probably be simpler than iframe, but not implemented yet Bug 1205323
Commandline thru search suggestions on the omnibar (this is a bit mad)
- chrome_settings_overrides
Find API
- Bug 1332144
- Demo
- How to replicate find links? Do we care?
- Can this be used to exfiltrate info about about pages?
Can't navigate to restricted URLs
