Neat URL by Geoffrey De Belie

Neat URL cleans URLs, removing parameters such as Google Analytics' utm parameters.

Example
Before:
http://www.phoronix.com/scan.php?page=news_item&px=Ioquake3-Auto-Updater&utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+Phoronix+(Phoronix)

After:
http://www.phoronix.com/scan.php?page=news_item&px=Ioquake3-Auto-Updater

Custom rules can be added using the global format or the domain specific format (parameter@domain). A domain specific parameter would be, for example, utm_campaign@phoronix.com.

Parameter rules
A parameter is something that starts with ?. You can add your own parameter in the options of Neat URL. The ? is ommitted in the options, so a ?ved parameter becomes "ved". There are a few exceptions to this rule (see below)

Parameters can be global (for every domain):
utm_source

Parameters can contain @ signs (domain-specific):
nb@tweakers.net

Parameters can contain @ signs with a wildcard so every subdomain will match too:
param@*.wired.com

Parameters can contain @ signs with a wildcard at the end of a domain name (matches every domain name which begins with "google" and ends in an unknown suffix:
param@google.*

Parameters can also apply globally (first rule), except for a (wilcard) domain (second rule):

ref
!ref@amazon.co.uk

The excluded domain always takes precedence. Should you include "ref" and "!ref", "!ref" will apply.

Other valid parameters (exceptions to the ? rule):
#xtor=RSS-8 (remove this parameter - be sure to include its value as well when you are using anchor tags)
#xtor=RSS-8@futura-sciences.com
$/ref@amazon.* (remove everything after /ref on amazon domains - this will only apply when there are no query parameters left after removing the filtered query parameters)
$$/ref@amazon.* (remove everything after /ref on amazon domains - this will always apply, even when there are other query parameters after removing the filtered query parameters - this option is available because the user should be in control but beware that double dollar signs are dangerous, it might break the URL)

Invalid parameters:
param@*.google.* (too many wildcards)
!ved (this is some random string - not supported, but it might work)
/ref@amazon.*$ (dollar sign should be at the beginning)

History
Neat URL is based on Lean URL. Neat URL contains a few improvements:
* set your own URL parameters on the options page (to reach feature parity with Pure URL)
* fixed for recent Firefox versions
* a nice animation in the toolbar (can be changed or disabled)
* domain-specific blocked parameters (to reach feature parity with Pure URL)
* wildcard domain-specific blocked parameters
