To install it:
- Install Greasemonkey add-on for Firefox: https://addons.mozilla.org/en-US/firefox/addon/greasemonkey/
- Make sure the monkey (probably at the top-right) is happy and colourful. Click on it if not.
- Install the tomsnow script by going to http://www.aurochs.org/zlib/js/userjs/tomsnow.user.js then
- Click on the Install button.
- Go and look at a new web page or reload one.
If you want to turn Greasemonkey off altogether, click on the monkey so he’s grey. If you want to stop individual scripts, click on the monkey, click on Manage User Scripts, and click on Disable next to the script.
These instructions were tested on Firefox 3.6.24 on Linux although I imagine they would be fine on any recent version of Firefox. I would be interested to hear anything confirming or undermining that assertion.
If you’re happy to play around, the snow is very customisable: you can easily alter the amount, speed, and style of snow, and so forth:
- Click on the monkey
- Click on Manage User Scripts
- Select tomsnow from the list
- Click on Options
- Click on Edit this user script (you will probably have to select a text editor at this point)
- Look for the section under the line of asterisks where more instructions can be found on how to make customisations.
- Save the file and reload any pages to see changes.
The Greasemonkey version of the script uses slightly different default settings to the previous version, in particular using a lower density of flakes as a huge blizzard of snow is not likely to be welcome if used on all sites one browses.
I haven’t found any particular problems and it doesn’t seem to stop any sites working although sites that are already very script heavy are obviously less happy about running more, e.g. Twitter which is fine but can get sticky, although Gmail seems curiously OK. My cPanel was the only one which was really not happy. When you manage a Greasemonkey script, you will see a box where you can specify websites that you don’t want it to work on. For example, put https://twitter.com/* and it will stop tomsnow working on that URL with anything after it.
