Clicking link with target="_blank" in Android doesn't work PLUS it breaks debugging and whole add-on

[Juraj-Masiar]

Is this a feature request or a bug?

Bug

What is the current behavior?

See the video:
https://www.youtube.com/watch?v=RxWO3wykTLA

But basically this is what is happening:

1. create any addon page
2. insert any link on that page with target="_blank" attribute
3. open the add-on page in Android
4. click the link
5. link is NOT opened and add-on get's broken, debugging doesn't work anymore

What is the expected or desired behavior?

Link should get opened.

This is because the browser.link.open_newwindow pref is overridden, changed from default 3 to 2.

Unfortunately, there is also a bug in web-ext run for Android that --pref=browser.link.open_newwindow=3 does not override the pref.

So as a work-around, visit about:config and reset the browser.link.open_newwindow preference (there is a Reset button that will restore the value of 3).

PS. Thanks for the detailed video. It made it much easier to see and debug the issue.
