I've written an Firefox extension to inject some script and css to all web pages loaded while this extension is installed.
Up to now, everything works fine. As soon I open a new page it loads en the script and css are injected. But what I want is that the extension is loaded before the page.
Example; I'm loading the twitter intent page. With my extension I'm customising this page. Right now I first see the twitter page, then the extension is loaded and my changes to the intent page are implemented.
What I want is the opposite. I first want to load everything from the extension, so as soon as the twitter page loads it is directly visible with my custom changes implemented trough my extension.
Currently I'm using the following lines to implement the scripts/styles. Although I've got the "contentScriptWhen" set to start, this won't fix my problem..
include: '*',
contentScriptFile: [data.url('jq.js'), data.url('js.js')],
contentStyleFile: data.url("css.css"),
contentScriptWhen: 'start',
I've 'solved' this problem. I'm loading the Twitter Intent (TI) page in the background as soon my index page is loaded.
While the TI page is loaded, it closes again. The page is in cache now, next time TI is loaded everything is instant correctly.
You can find more about background loading here: developer.mozilla.org/en-US/Add-ons/SDK/High-Level_APIs/tabs
In this fiddle is shown how I did the trick; FIDDLE
You can also start by preventing the document from getting parsed then on the side fetch the same document, make any modifications on the fetched document and inject it in the page. Here is what I currently use https://stackoverflow.com/a/36097573/6085033

I'm developping a jqm application with spring mobile in the back-end.
Whenever I hit the browser refresh button on my mobile phone the page is completely devastated afterwards. Browsers back-button works properly.
The data are still available due prg pattern (flashAttributes in Spring) after refresh. Only the view is malformed.
Any ideas how to solve this problem?
From jQuery Mobile docs :
The simplest approach when building a jQuery Mobile site is to reference the same set of stylesheets and scripts in the head of every page. If you need to load in specific scripts or styles for a particular page, we recommend binding logic to the pageinit event (details below) to run necessary code when a specific page is created (which can be determined by its id attribute, or a number of other ways). Following this approach will ensure that the code executes if the page is loaded directly or is pulled in and shown via Ajax
So what happens is - in jQuery Mobile, the scripts and styles defined in the head are loaded only once. So, in normal conditions, it works fine, as all the pages will use the scripts loaded from the first page.
But. When you refresh a page in-between, it triggers a page-reload instead of the ajax navigation model thatjqm uses. So all the scripts and styles loaded from the first page will not be included from here on out.
What you need to do is "reference the same set of stylesheets and scripts in the head of every page", so that even if you hit refresh in the middle, the scripts and styles that had been loaded from the head of the first page are loaded again.
I recommend you read the docs from the above link fully to gain a better understanding.
I know using Ajax you can load parts of page, but how would you load a different URL (not just hash change) without actually loading full page?
The demo can be found at rottentomatoes.com
Go to home page. On the left hand side of the page, click on one of the Opening Movies.
Now scroll down by 20px appx., to understand the effect.
Click on another Opening Movie.
Now the URL is changed, but full page is not loaded. Or that is what is my perception.
How would you do that?
I don't know fully about this but by using ajax and history api you can do this.
Just try the following links may help you

I'm adding a facebook share button to each post on a Wordpress (Using Facebook Share Button New plugin), it works ok for each post/page except when i'm loading them trough ajax, the result it's a normal Facebook like button but the popup (to write a comment) appears inside the button it is not expanded.
To check go to: http://iwanttobeher.com/ and then click on any face at the bottom of the page, then test the like button and you'll see what happens.
I don't know what to do, i tried to FB.XFBML.parse() after loading the content but the result is the same.
Switching to HTML5 didn't help in our case. What did was to remove the FB object just prior to new content being inserted into the page via Ajax:
delete FB;
wrapper.html(response.data);
We reload full pages via Ajax and so new page content recreates the FB object and re-initializes XFBML anyway. Not sure if this workaround would work if we reloaded only parts of the page though.
The original answer is here.
I've managed to fix it by changing the implementation to HTML5 instead Iframe or XFBML using Facebook's tool to generate like buttons: https://developers.facebook.com/docs/reference/plugins/like/
I have a JSP page, where some parts of the pages are loaded from the backend using AJAX. For example, when I first open the page, the URL is http://www.made-up-domain-name-because-of-stack-overflow-restrictions.com/listUsers.do. The page contains an "add user" button, which loads HTML content (containing a form etc.) from the backend to the div-element with id "addArea". The URL stays the same the whole time (naturally), as the request is done in the background.
The problem I have is that the content loaded using AJAX is not completely viewable with any means.
Using Firefox I can see the new HTML with the Firebug add-on and "Inspect element", but the content within the script-tags is not visible that way (also not in the "Script" tab in Firebug - only the originally loaded scripts appear there). If I use "View page source" in FF a page reload is executed and I don't see the newly generated content (I only see the content of page http://www.made-up-domain-name-because-of-stack-overflow-restrictions.com/listUsers.do as it was when first loaded).
With Chrome I have the same problem as with Firefox.
Using IE I see only the original source.
Of course I can work around this by adding debugging mechanisms to the JS code and working half-blind, or moving parts of the JS code to external files etc., but if by any means possible, I would prefer to just view the code loaded using AJAX. Any suggestions, perhaps using some add-on?
Update: There is a better way: see the accepted answer for this question: How to debug dynamically loaded javascript(with jquery) in the browser's debugger itself?
You can use the JavaScript Deobfuscator extension for that. It can show you what scripts are compiled/executed on a webpage - including the ones that were loaded dynamically.
I want to create a Firefox Extension which will display a webpage. It will be like user should write a something in browser like "about:" or even a button would do ?
How can i load the WebPage in Firefox. The user should have a feel that a webpage is being loaded.
PS: I have javascript and CSS in that Page.
If i cannot make then what changes do i need to make in the web page for that change.
I also want to connect to a server and fetch XML data and want to display process that data and and display it on the page. I am developing this extension as my page is static and HTML/Javascript does not allow cross domain queries. I hope that cross-domain queries are possible if i use extension.
There is Browser XUL object that acts a an standalone browser. You can load any document inside that.
