CheckBoxMate for Greasemonkey
"Check multiple checkboxes with ease by drawing a box around them to automatically select them all." Converted from nrlz's amazing CheckBoxMate Firefox Add-on (https://addons.mozilla.org/en-US/firefox/addon/9740). Works with Firefox 3.6.3.
Resizeable Text Fields
Based on Resizeable Textarea 0.1 (https://addons.mozilla.org/de/firefox/addon/3818), original coding by Raik Jürgens. Added support for select lists and horizontal resizing of input fields by Florian Höch. Should now work on all page types (XML/XHTML/you-name-it).
