Please don't throw an Error when vAPI is not available

[herrernst]

Describe the issue

I use Chrome for developing and debugging websites and thus always have developer tools open and breakpoint on exceptions enabled. If I am debugging websites with SVGs embedded as <object> I always get an exception at

uBlock/src/js/contentscript.js

Line 90 in 64c92a9

throw new Error('uBlock Origin: aborting content scripts for ' + window.location);

which is very annoying and forces me to disable uBlock origin.
Please could you just log with console.error() instead or something like that? Thank you.

Would it at least be possible to not throw the error when uBlock Origin is disabled for a site? Thanks

[gorhill]

Content scripts are declared in the manifest and injected unconditionally by the browser. What would be nice is the chrome API allowing to declare document type filter options in the manifest.

OK, thanks nonetheless.

I do plan to do something about this, it's just a question of free time and I do not consider this an issue which is at the top of the list.

I found an obvious solution to not cause the debugger halt on this error: simply blackbox the content script!
