Migrating from SDK to WebExtensions; Multiple listed versions possible?

Hi Jorge,

That's just what we wanted to hear, thanks for the quick response!
We have 2 more questions that I hope you are able to answer as well.

Our extension essentially is a replacement for the new tab page. After
installing it, when a user opens a new tab, 'https://start.me' is opened.
However we'd like to make this optional; Either start.me should open, or
the default new tab page (about:newtab).

Unfortunately, about:newtab is a "privileged page", so the extension is not
allowed to open it (an Illegal URL error is thrown). Do you know if there
is any way we can work around this problem?
I did a lot of searching lately, and checked out various other extensions
that have been ported to WebExtensions, but couldnt find a solution. I
found this bugreport which precisely describes this problem:
This one is also related:

The second question we have has to do with focussing &
selecting/highlighting the URL in the address bar. When a user opens a new
tab, they are redirected automatically to https://start.me. However, we'd
like the full address in the address bar to be selected/highlighted, so
that the user can immediately type in another URL.
Would you know of a way to achieve this? I did quite a bit of searching on
this too, but wasn't able to find a solution. Several extensions that
currently do this have announced that they won't be porting their
extension, because of the limitations that come with WebExtensions, like:
I hope there is some sort of solution for this.

Thanks in advance,
