Install multiple firefox extensions

I’m a full time web developer now. Million thanks to Firefox, web development is made much much easier. To make the web development process easier, there are many many extensions.

A few of them I use for my development,

1. Firebug
2. Web Developer
3. ColorZilla
4. MeasureIt
5. ViewSourceChart
6. FireCookie
7. YSlow
8. Delicious.
9. Twitterfox
10. CSS Viewer

One problem I face when I have to work in a new machine or a new user account is installing these extensions. Not that I face this problem everyday, but this is something which is very irritating. One simple solution will be to backup the extensions folder and protect it safely, so that I can use it on any machine I use. Finally, I wrote a simple shell script which does this job.

#!/bin/bash
declare -a EXT LINK

#Let us populate the extension and the link for the extension here

EXT[0]=”ColorZilla”
EXT[1]=”Firebug”
EXT[2]=”WebDeveloper”
EXT[3]=”MeasureIt”
EXT[4]=”ViewSourceChart”
EXT[5]=”CSSViewer”
EXT[6]=”FireCookie”
EXT[7]=”YSlow”
EXT[8]=”SenSEO”
EXT[9]=”Delicious”
EXT[10]=”Twitterfox”

You can download the latest version of this script from here.

Logic : Download the xpi file. Unzip it. Copy it to extensions folder.

Disclaimer: Download and run the above script at your own risk. I have tested it with many cases. Worst case, this will remove all your extensions from all your profiles (OMG) (Happened to me once). Also, I would advice you not to run this script in windows. I haven’t tested it there.
