I'm trying to create a responsive testing browser using chrome extension. Currently I'm using Iframes to render the web-contents. However iframes have a lot of issues opening third party websites in cross-domain origin sites. I found that webviews can quickly render the websites without any CORS or cookies issues. Is there any way in which I can use webviews in the chrome extension? Webviews are used by chrome apps which runs on chromium. So there might be some ways in which we can modify the chromium source code to allow webviews to open in extension.

I'm looking to create a chrome extension that loads a mobile first web experience as content. The webpage that I'm loading requires authentication ( through Google ). I'm just wondering if this is possible with the current security limitation of chrome extensions.
I am working on a webextension that will inject some ui in some pages. this ui will mostly be inside an iframe to better isolate css.
the problem I have is that I can do browser calls from inside the iframe scripts on chrome (I am also using webextension-polyfill) but in firefox I get browser is not defined error.
Am I missing something?
it seems like the errors I get are a firefox bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1443253
a relevant comment on the bug page says
Chrome supports out-of-process frames, so Chrome is able to render an extension frame in an extension process (and the iframe can safely be granted access to extension APIs - https://bugs.chromium.org/p/chromium/issues/detail?id=550151 ).
In contrast, Firefox does not support out-of-process frames, so the iframe is handled by a non-extension process (with only limited access to extension APIs).
I create chrome extension. When user hits special shortcut this extension will add iframe to current active page in chrome. This iframe will load js from external resource (my site) and show some data. Is this allowed (to load external js inside iframe)?
I did not find any restrictions in chrome developers about that, but I worry if my extension will not pass check at chrome webstore.
You can insert any HTML code into the DOM, but if you're inserting an IFRAME, it will be limited by same-origin restrictions which will likely prevent the embedded Javascript from running unless both websites share a common domain and protocol.
See https://developer.mozilla.org/en-US/docs/Web/Security/Same-origin_policy for further details.
This is something like a chrome extension changes the elements of a web page dynamically.
I am wondering if i can change the DOM elements of a chrome app from another chrome app or extension.
If this is possible, how can I do that ?
========================================================
Example:
There is a standalone chrome app working on the desktop
There is another app / extension works like a chrome app debugging tool which can access the content of that standalone app
The answer can be no, since when you are saying the DOM elements of a chrome extension, I guess you mean the popup/options page for the extension, its url starts with chrome://extensions while content script can't access this kind of page.
The answer can also be yes, since if you have control on both of the extension, you can do Cross-extension messaging, in this way, to some degree you can achieve change the DOM of a chrome extension from another extension.
I'm writing an extension.
A part of this extension contains an html page.
I'd call that page, also as a Google Apps,
inserting an icon between applications of chrome.
It's possible create a manifest file to integrate the chrome app with chrome extension?
No. You'd create both an app an an extension, then encourage the user to install both if you detected that one wasn't installed.
There is an outstanding feature request to allow bundled installations of multiple apps/extensions.
