Firefox 13 and 14 will not install properly on my windows 7 starter. Also I cannot get the Scrapbook addon to work. Can you tell me why ?

Question

I have tried to install Firefox 13 and 14 on my netbook, running a Windows 7 starter OS. The installation begins to go smoothly from the setup.exe file; but after the installation seems complete, and I press the 'Open Firefox' button the firefox programme can be seen to start opening because it accumulates about 50mb of private bytes RAM on the windows task manager or on the 'process explorer' utility program by sysinternals. '''However the firefox screen/window never opens up and so firefox does not seem to be properly installed.'''' Also I have had problems with getting the Scrapbook" addon to install properly. I have another computer, a laptop, running XP Home, and I can get the Firefox 13 or 14 to install but it is on this other computer that I cannot get the 'Scrapook' addon to install properly; There is no notice on the Addon page saying the 'Scrapbook' addon does not work on Firefox 13 or 14, and the addon does install, but not properly, so it does not work.
I have the old Firefox setup.exe files, and so I have managed to install an old version, firefox 3 or 4, on an external hard drive. I have successfully got this old firefox to work on the XP Home laptop from an external hard drive, and can successfully use the 'Scrapbook' addon in this way.
I cannot understand why I have problems with Firefox 13 or 14. I think I first noticed the problem about 'Scrapbook' with Firefox 12.

It seems your Mozilla installation is broken. Try the following steps to fully uninstall Mozilla Firefox:
1. Uninstall Firefox as you would normally do.
2. Open a command prompt as administrator.
3. By using the cd and rd command, remove Firefox AppData and Roaming folders, for example:
C:\Users\USERNAME> cd AppData
C:\Users\USERNAME\AppData> cd Local
C:\Users\USERNAME\AppData\Local> cd Mozilla
C:\Users\USERNAME\AppData\Local\Mozilla> rd /s Firefox
C:\Users\USERNAME\AppData\Local\Mozilla\*.* - Are you sure? (y/n) y
C:\Users\USERNAME\AppData\Local\Mozilla> cd ..
C:\Users\USERNAME\AppData\Local> cd ..
C:\Users\USERNAME\AppData\> cd Roaming
C:\Users\USERNAME\AppData\Roaming> cd Mozilla
C:\Users\USERNAME\AppData\Roaming\Mozilla> rd /s Firefox
C:\Users\USERNAME\AppData\Roaming\Mozilla\*.* - Are you sure (y/n) y
C:\Users\USERNAME\AppData\Roaming\Mozilla > exit
Remember to press Enter each time.
4. After that, open a hard disk clean-up tool (such as CCleaner or Windows built-in) and remove all temporary files from your computer.
5. Restart your computer. Download '''again''' the Firefox package from [http://www.mozilla.org/es-ES/download/?product=firefox-14.0.1&os=win&lang=es-ES Mozilla official servers] and try to install Firefox. If the problem persists maybe your computer has a problem or is infected with viruses.
About the Scrapbook add-on, I could get it to work. It has no icon when docked to the toolbar, but you can anyway open it. Right-click a button on the toolbar, click Customize... find the Scrapbook icon, drag it to the bookmarks bar so you can see the icon and click on it to open it. Whenever you need to save a page, right-click that page and choose Save page.
