Any developer worth his salt knows about Firebug and its JavaScript console. I use it all the time to tinker with web pages, test stuff out and debug my own pages.
But sometimes, if I'm *cough* hacking *cough cough* someone else's page, I need the added power of jQuery! But what if the page doesn't have it?
Simple – load jQuery from a remote source manually through a javascript: call.
Save Favelet
Just drag the link below to your Links toolbar, then click it on any page to jQuery-enable it.
Test it out!
Save the Favelet and click on it (or just click the link above), then: animate page.
Simple!
