Chrome Extension - Use Another HTML Source - google-chrome

I'm creating a extension and here is what I want to do.
I have site "www.aaa.com" and the extension I developed can read and navigate DOM element by javascript. However, when I click the extension icon, I'd like get and read the HTML source from "www.bbb.com".
The current page is "www.aaa.com", but want to get the source of "www.bbb.com" in the current page.
How can I do this??

Open html file in a new tab instead of downloading it

For my Trac plugin, I have made an export script which converts contents to a different format. The result is an HTML code.
When I click the link, some browsers open the HTML code in a new tab, while others offer to download it as a .print file, depending on their specific settings I think. Opening this .print file shows the same HTML page as opening it directly, but locally instead of from the server.
How can I force it to always open in a new tab?
I think it might be a mimetype issue. If it is, which mimetype can I use to tell the browser to open the HTML code directly? I am currently using text/html as mimetype.
EDIT: some more info
To give some more insight, adapting from a comment of mine below:
I do not create the link myself. The link is provided by Trac, the bug tracking software the plugin is for, and what I do is implement the method that creates the HTML code and let it return the HTML code along with the mimetype. Trac then returns the HTML code either as a file, or as a new tab, when clicking on that content conversion link. What I am searching for is a possibility to specify in the HTML code or mimetype that it gets opened in a new tab directly.
Maybe there is some kind of mimetype specifying the (HTML) text as an HTML web document instead of HTML file (if that distinction even exists).
Or an HTML/XML header or doctype specifying whether it gets downloaded or opened by a browser. I think the browser need to get that information from somewhere.
Or maybe there is an option to set in Trac.
I hope these ideas of mine about what could exist can help those of you who are versed with either or some of these to find a solution. I could not find a solution through my research yet.
If you have a link that "directly" opens (not in a new tab) and you want it to open a new tab, one way of doing it is
This will create a blank page, then paste the link there automagically and thus you will have a new tab with the desired page.

Google Chrome Extensions: Get Current Page HTML (incl. Ajax or updated HTML)

In my Google Chrome extension, I need to be able to get the current page HTML, including any updated Ajax HTML (unlike the browser's View Source command, which doesn't update it).
Is there a way to get it as a string in my Extension?
Suppose my extension is a right-click context menu called "View Actual HTML Source" which should print the current HTML to the console, or maybe count the number of certain tags there. I wasn't able to find an easy answer to this.
You can get the current state of the DOM as HTML programmatically using document.documentElement.innerHTML
Or just use Developer Tools
I followed the exact solution here, and this gave me the Page Source HTML:
Getting the source HTML of the current page from chrome extension
The solution is to inject the HTML into the Popup.

Google Chrome extension - to open new tab directed to url when a certain url is searched in current tab?

I am very new (started today) to writing chrome extensions but need to write a 'fairly simple' one for tomorrow...
I am really struggling to get my head round it though!
I need to write an extension that opens a new tab or window (whichever is easier!) directed at a predefined url is opened when a certain URL is searched in the current.
An example of this would be if the user typed in www.facebook.com I am trying to get the extension to then open a new tab/window with www.google.com in.
Any help would be much appreciated!
Thanks
Will
In your html of the extension you can specify an anchor tag for the action button which opens a new tab like this
content of the anchor
or if you want to do it programmatically you can
window.open('http://google.com','_newtab');
You cant get at the contents of the omnibox unless you use the omnibox api, which means they have to specify your keyword first before your extension can get at the contents. You could make it open another page once they have gone to a url. You could use a content script that has a matches field that matches the page your interested in and then open a page accordingly.
Content Scripts

Tabs
You can use the tab api to get the current tabs details if your not in a content script. If you are in a content script you can use window.location as stated by Encore PTL. You can also use the tab api to open a tab.

google chrome & other: saving xml+xsl as html

Page of the site, built on a client-side xml + xsl technologies, some browsers like Firefox, Google Chrome, etc.. save the file as pure xml. Without the xsl and css. As a result, saved the page looks horrible. Is it possible to force the save page as html?
If you use Firefox's save dialog (6.0.2), you can see that one of the options is Web Page, Complete. This means that just like normal XML, it also finds all the other linked documents (like CSS files for example) and saves them in the appropriate directory for offline browsing.
If your browser has this feature, then you can see it in its save dialog. Otherwise, it simply doesn't have it.
In Chrome: open F12 to bring up developer tools. Go to Elements tab and right click on html-element and select Copy../Copy element in context menu. Paste into you text editor of choice and save it as an html page.

How can I get a chrome extension to affect the webpage itself? (not the popup)

I have been reading the dev guide but haven't been able to work out how to put my own codes into webpages
I know it is possible because AVG uses it (in it's link scanner), and FastestChrome extension uses it too (highlight something and a link to a search pops up).
I have a backgrounded page but I can't get it to effect the webpages I go on (permissions are correct as I can get css to effect)
I am probably missing something really simple :/
It's not intuitively presented in the documentation but your background page can not access the current webpage b/c they are in different contexts. In other words the background page is it's own separate page so it has no access to any other page's DOM.
If you want to affect the page the user is viewing in the browser you will need to use what is referred to as a "content script".
If you want to communicate between content scripts and the background page you will need to refer to the message passing API. Check out my extension's source code for reference. I do exactly that.
Just remember...
Background Page: used for general logic in your extension, not anything page specific.
Content Scripts: are loaded into every page the user sees, and can manipulate that specific page.
Those probably use Content Scripts to inject Javascript into webpages. These scripts run in the context of the web pages and can access the DOM.
You can either define a script to always run in a web page by declaring the script file in the extension manifest, or you can use your background page to inject a script when needed.
