Firefox for Web Developer? - firefox

Is there any FireFox plugin which acts the same as IE8 developer tools in a way that it has an option to switch from different modes or versions?
I had many issues when installing different versions of FireFox in just one machine. I now have 3.0, 3.6, 4.0.1 and 5.0.1 of FF but I got a problem regarding add-ons, it seems like they share just one location where add-ons are in.
If I open FF 3.0, since some add-ons are latest version for 4.0.1 and are not compatible with FF 3.0, it will disable them, then when I go back to the later version, add-ons which was disabled by the older FF will be gone.
Anyway my platform is Windows 7 32-bit.

Start firefox with following option
firefox.exe -ProfileManager
For each profile you can add individual addon's which do not conflict with other profile addons. Ensure you give different names for different profiles in different firefox versions.

How to integrate add-ons (.xpi) into my custom Firefox build?

I'm compiling Firefox 44.0.2 on my Windows machine using the official guidance: Simple Firefox build. I want to integrate some custom add-ons to my build. The add-ons are usually .xpi files.
How to do this?
The documented way to do this is to include the .xpi file with the distribution in the directory:
[Firefox install directory]/distribution/extensions
The add-on will then be installed in (copied to) each profile upon the first use of that version of Firefox with the profile. The copy of the extension in each profile will be automatically updated using the normal auto-updating procedure. Effectively, the add-on will be treated as if separately installed in each profile. The user will not be asked to confirm installation of the add-on.

Is there any Firebug version for Firefox Nightly 13.0a1?

I googled for the add-on, but when I go to Mozilla's website, it shows a message that there is no Firebug add-on for 13.0a1. Is there any Firebug version available for this Firefox version?
The last Firebug version working with Firefox 13.0a1 is 1.10.6, as you can see in the compatibility table at addons.mozilla.org.
Though Firefox 13.0a1 is outdated for years. You should download the latest stable version (currently 34.0.5) or the latest Firefox Nightly (currently 37.0a1).
The Firebug version compatible with this Nightly is 3.0, which is currently in alpha state and can be downloaded from getfirebug.com.

How to use the latest version of WebKit when making a browser in Eclipse on Windows? And is it possible to by-pass the Safari requirement?

I made a browser before in Visual Studio. But events occurred and Visual Studio 2010 dosen't work the same with Win8. So I'm trying to make a browser now for the next version based on Webkit, and I'm wondering, if I follow the instructions here (http://www.eclipse.org/swt/faq.php#howusewebkit) wouldn't I have an older version of WebKit? Because Safari is discontinued on Windows and Chrome now uses Blink. Also nowadays people don't have Safari on Windows, so is it possible to by-pass? Because on that website it states that the user need Safari in order to work.
So it boils down to how do I get the latest version of WebKit if I'm developing on Windows? And is it possible to by-pass the Safari requirement. Sorry, I'm sort of new to Eclipse if I sound noobish.

Finding incompatibility in Firefox addon

I have an custom addon developed for our workplace (using the add-on SDK) that was originally developed for FF4.
When FF5 came out all I had to do was rebuild the XPI. FF6 was able to use the same XPI.
Now I'm trying to get it running in FF7, and it's not working. I get a "this add-on is not compatible with Firefox 7" when trying to install it.
I've read this blog post:
http://blog.mozilla.com/addons/2011/07/19/firefox-7-compat-looking-to-8/
And from what I can tell none of the changes affect my add-on.
Also running this validation test
https://addons.mozilla.org/en-US/developers/addon/validate
Yields no errors or warnings.
Any clue on how to find out what makes FF7 think it incompatible?
You should use the newest version of the Add-on SDK to rebuild your add-on. Right now, the latest version you get offered on the SDK download page is Add-on SDK 1.1, released on September 13th. It will mark add-ons compatible with everything up to Firefox 8.0a1. You are most likely using an older version, e.g. Add-on SDK 1.0 would only mark add-ons as compatible with Firefox 7.0a1.

Selenium IDE 1.0.2 in Firefox 3.5 on Mac

I've tried installing Selenium IDE from their website. The newest version - 1.0.2 - installs fine. After restarting Firefox, I go to "Tools" > "Selenium IDE", and this window opens:
No more happens. I can access the menus of Selenium (Create New Test Case, etc.) but clicking them doesn't have any effect.
I am using Firefox 3.5.3 on Mac OS 10.6.1. The version I installed of Selenium IDE was 1.0.2 from http://release.seleniumhq.org/selenium-ide/1.0.2/
Is there any way to make it work? Or is it just me who cannot make it work?
Generally the conflicting extension are themes, for not having to create a completely clean profile and loose all your add-ons, try using firefox in it's default theme and see if that works better.
