If you see screenshot above, it has only an option to allow this extension on specific sites. Is there any option to disallow to specific sites?

If I had to modify Firefox/Chrome to only allow a specific list of websites, without the use of browser extensions. Where in the source code would that be?
I know the Stylus and Stylish (not recommended) browser extensions that can re-style a given website (basically by customizing CSS).
In this comment, the author states this can be done via "user stylesheets".
How is it possible to use "user stylesheets" to modify the style of www.example.com and a different style for www.example2.com?
Is it something that can be done without requiring a third-party browser extension, if so, how/where in the browser options should we add our custom CSS?
This seems to be deprecated nowadays:

Remove the concept of user stylesheets.
-The support for this has been removed from Chromium already.
This is now just deleting dead code.

As a web developer, is there any way to prevent a user's Chrome extensions from being applied to my site? i.e. a header, meta tag, anything? Additionally, if there is, is there also a way to whitelist particular extensions?
It's not possible. At the web server end, you are only only able to control what the browser will allow you to control. In simple terms, this means you can control the data (HTML, javascript, headers etc) that you send back to it. That's about it.
Can't you create a Content Security Policy (CSP) and block inline javascript and only allow javascript from specific domains? You could even create a CSP in report-only mode and collect violation reports via something like https://report-uri.io/
I want to know whether the APIs available to Google Chrome extensions enable changes the appearance (colors, styles, etc.) of page contents without modifying the HTML?
For example, when spelling or grammar support is enabled, Chrome will underline phrases that contain problems. The browser doesn't appear to change the markup of the page to accomplish this. Does the extensions API have that kind of feature?
I'm thinking of writing a sort of writing assistant extension that would behave similarly to the spelling or grammar checkers. I'd like my extension's display to be similar to those checkers.
I am working on a C++ project that will read a Chrome Preferences file and enumerate Extensions and Plugins from it.
The main requirement is that only those extensions and plugins displayed in chrome://extensions and chrome://plugins should be used/displayed by my app.
Does anybody know which setting for an Extension determines if it is displayed under chrome://extensions? I can't find the logic behind...
Does anybody know the set of rules that will group the plugins as they show in chrome://plugins? Is it name, version or ... I can't find the logic behind as well
This is only a partial answer, but to my knowledge there is no setting to prevent an extension showing up from the chrome://extensions tab - everything installed will appear (you can hide the icons that show up in the toolbar, but everything will be visible in chrome://extensions. Therefore (again, according to what I've read and my somewhat limited experience), all installed extensions appear in chrome://extensions (this is primarily for security reasons).
Regarding the plugins, which particular grouping are you referring to? My groupings appear to happen when either there are multiple files in the same package (inclusive of Firefox plugins as well, oddly enough). See here for a little more detail, and sorry if that wasn't as specific as you're looking for :)
