So.. I'm always looking to expand to use tools to make my life easier and get the job quicker...
What are some of your bookmarks / JS bookmarklets (not stand alone programs, browser add-ons, etc.) that help you during your web development times?
I'll start off with my list:
Visual Event JS Bookmarklet, let's you see what events are attached to what DOM nodes.
CodeViper Bookmark, a PHP pastebin that shows the output of the code. Useful for IRC/IM help
JsFiddle Bookmark, similar to CodeViper, it's a JS (multiple frameworks available for use), HTML, and CSS pastebin that shows the output of code. Useful for IRC/IM help
NoisePNG Bookmark, creates a repeatable .png tile with noise (you choose the amounts)
border radius Bookmark, quickly create cross-browser (webkit, gecko, standard css3) border radius just by changing the numbers on the corners
PreMailer Bookmark, Check & tidy up HTML email source codes before sending to your userbase
