I use Firefox but have been watching Chrome carefully with an eye to switching, but it seems that Google still has a bit of work to do before it matches Firefox's extensions. This is an interesting article because it gets into the details of Chrome extensions enough to pick out some of the shortfalls. <a href="http://download.cnet.com/8301-2007_4-10416103-12.html?tag=contentMain;contentBody" target="_blank">http://download.cnet.com/8301-2007_4-10416103-12.html?tag=contentMain;contentBody</a> eg. - Adblock Plus, the #1 extension for FF ... 'Despite the name, <a href="http://download.cnet.com/AdBlock-/3000-2378_4-10976589.html" target="_blank">AdBlock+</a> should be avoided. It's not made by the same publishers who manage <a href="http://download.cnet.com/Adblock-Plus/3000-11745_4-10636539.html" target="_blank">AdBlock Plus</a>, the popular and effective ad-blocker for Firefox. This is actually a fairly serious problem with Chrome's extensions, where unknown entities are appropriating identical or similar names to well-known and trusted Firefox add-ons for what amount to nefarious purposes. So far, the ad-blocking extension that most users seem to be trusting in Chrome is <a href="http://download.cnet.com/AdBlock-/3000-2378_4-10976589.html" target="_blank">AdBlock</a>, but don't be surprised if it causes more problems than it solves until there's more consensus on these name-squatters' <a href="http://download.cnet.com/8301-2007_4-10416103-12.html?tag=contentMain;contentBody" target="_blank"></a> Xmarks for synching bookmarks is only Beta.
