Is it possible to replace built-in about pages? - firefox-addon

I am pretty new to developing addons but I'd like to make one that modifies/replaces the about:netError page.
I could not find tutorials or documentation anywhere, is it even possible?
Thank you.
Edit: I need to edit the xhtml file which shows the info about error.

Menu dropdown messed up after translating page using Google translator

My menu drop-down is now messed up, after I translated the page using on-the-fly Google translater. It refuses to recognize CSS classes I have created and used for exclusion (e.g, I have a class like this class="notranslate", which is no no longer working).
For demostration purpose, I have source code
here
Note: Must register to the site first. Any help would be appreciate it. Thanks
Not sure what is going on but look at this tool: Translate This
This uses the Google Translate but is easier to use.
Hope this can help you.

How can I find where actually is the theme file?

I am new to Symfony and I need to work to a large project with many themes to modify them. How can I find where actually is the theme file in which module, just looking at the HTML browser output? Or do I need to look somewhere else, routing for example?
What you want to do is use the Web Debug Toolbar.
Once you have that running on the page, using appname_dev.php, simple click the view link and it will show you which templates have been used. If you need to know which layout to use then use logs link, click none the sfPHPView.

Markdown editor in ASP.NET MVC

I'm looking to use markdown in my website, and I'd like the editor (or something similar to) the one used here at Stackoverflow. As far as I can see, I can get this from the google code site.
What I want to know is, how do I then use this in my site? I see perl files etc included with this.
Anyone done this before, or have links to good documentation (the site of the original WMD appears to have disappeared).
Here is StackOverflows fork/branch:

How to open a popup using Ajax

I'm using Ruby on Rails 2.3.8 and I would like to know how to open a popup using Ajax, instead of jQuery, so when I click in the link that will open it, an action is executed to load some collections and other stuff.
Thanks in advance!
First i think you are messing up some concepts here.
JQuery is a javascript framework and AJAX is a set of development methods.
See: http://en.wikipedia.org/wiki/Ajax_%28programming%29
and: http://en.wikipedia.org/wiki/Jquery
I think that you mean "How do i open a link in a lightbox like screen instead of a javascript popup".
(correct me if im wrong interpreting your question :)
Please take a look at some open source tools like:
http://chriswanstrath.com/facebox/
http://fancybox.net/
And there are tons and tons of other alternatives.
Just google for "lightbox"

Firefox Add ON - To Check for Absolute and Relative Links

Does anyone know if there is some type of tool, preferably a Firefox add on that can check the links on a page if they are absolute links (going to another website) or relative links (within the website)...
I have searched on Google, and the Firefox add ons and haven't seen any. How hard would it be to make my own? What do you guys suggest.
Did you checkout ExNewT ?
btw, it is not that hard to search on addons.mozilla.org, you should have do it yourself.
Write your own Javascript to go through all the elements in the document, or maybe there is a better way to access links using a Mozilla class, and use this guide to discern between absolute and relative links.
