» Installing Greasemonkey Scripts (Userscripts)
» Procedure 1

- Whenever you click on the link to userscript, a window pops up
- Click on the install option and the userscript will be installed
» Procedure 2
This procedure should be used when clicking on the link of the userscript yields a page with the userscript source and no pop-up window is experienced.
- Click on the tools column of your Firefox Browser
- Watch out for a Greasemonkey Option
- Click on it and find ‘Install This Script’ option to install the userscript
» Procedure 3
This procedure should be used when clicking on the userscript popup’s a window which gives you an option to save the userscript.

- Save the file (userscript) in your computer – say on desktop
- Right click on the saved userscript and navigate to ‘Open With’ option
- Choose Firefox and the userscript will either display source for which you have to follow procedure 2 or a Pop-Up window for which you have to follow procedure 1
» Managing Your Userscripts
In order to view the userscripts right click on the monkey logo in bottom right of your screen and choose ‘manage userscripts’
- In the window, you will have all your installed userscripts listed.
- You can uninstall, edit, and perform other operations in this window.
These were the common installation techniques which can solve common problems in userscripts installation. If you still have any doubt or if you are facing any difficulties, you can leave a comment so that we can guide you further.

























hey after clicking ‘manage user script’,i cant edit any user scripts……..
wen i select edit,nothing happens….
please help me out……….
@akhil – you cannot edit userscripts in here. In case you wish to edit or customize an userscript follow these instructions:
1 – download the userscript to your desktop
2 – right click and select open with notepad
3 – edit and save the notepad file
Let me know if your goal is attained else give a broader explanation on what you exactly want to do.

@samey
First, your Greasemonkey should be enabled.
Then Install your script.
Then in Firefox, go to Tools > Greasemonkey > Manage User Scripts
Select the Userscript from the left section and click edit.
Use Notepad to edit and edit the script as it says to do.
