[chromium-discuss] Prevent injecting extension content scripts for particular domains

[Artyom Pranovich]

Hi guys,

I'd like to know if there are any places in Chromium codebase where we can
restrict some domains from running/injecting content script on them?

Just for example, imagine I'd like to block running content scripts
injected by 'Extension X' / or by all extensions on any pages of my site
hosted on **.mydomain.com*. Of course assuming that I have custom chromium
build.
I'm pretty sure that there is such place, because *chrome://* pages already
do that (more info about blocking injecting content scripts on chrome://
pages is here
<https://groups.google.com/forum/#!topic/chromium-extensions/FORua7gwsqI>).

So if someone could guide me through the flow how I can do that, or just
give me directions to particular Chromium codebase place where I could look
into - it would be awesome!

Thanks,
Artyom.

chrome:// is not examplatory here, because it uses a different scheme
(chrome://) as well as rendered by a different (more privileged) type of
processes.
However, the webstore (chrome.google.com/webstore) is excluded from content
scripts, so you can use cs.chromium.org to find the code that regards that
URL until you get to the specific method that causes content scripts not to
apply and add your cases there.
