OnlyWire works good for me, and usually my friends said the same. Onlywire is easy just install the Add On then restart the firefox browser and you've done, next just one click and your link will submitted to 25 and more social bookmark. It's absolutely free, they only ask you to install they FF Add on. That's all.
3 Plugins I use almost everyday for link building and form management: * Roboform << REALLY GOOD for password and form management * FLEM << nice if you have a list of sites and you want to go one after the other without going back and forth from your notepad urls and the browser * iMacros << for macro creation! this one is really powerful but you need basic coding/scripting knowledge
