I’m always on the lookout for some useful browser extensions to make my life a little easier. My favourite browser is Chrome because it’s fast, clean and stable. Now that extensions are available, it makes sense to compile a little list of useful ones for the semantic web. There aren’t as many available as for Firefox you’ll notice, but it’s early days! Still, here are my 3 picks.
- RDFView:
RDFView is an extension that will find links/references to RDF pages and allow you to open them using an online RDF viewer.
- Microformats:
This extension auto-detects Microformats on the page you are reading and upon finding one will display an Microformat icon in the Omnibox, allowing you to click on it to preview the Microformat content. (Only hCard for now)
- Omiod:
It’s actually called “Meta SEO Inspector” and “Omiod” is the name of the developer, but I prefer the developer name 
It’s made for developers who need to check basic SEO stuff like for example meta tags being in place, but this extension also picks up on XFN tags, Microformats, and more. It flags issues and is mainly SEO oriented.
This is quite a lean offering compared to the Firefox options but at the end of the day you do only need one tool (ideally) that works well for you.
If you know of any others, please share 
Hey great post some good information shared here especially for those who are new to chrome or thinking about changing browser.
Thanks Kenneth, glad you appreciated it!
those are great extensions, i’m glad chrome is opening up and getting some more extensions.
Thanks for these extensions, not heard of them before. I’ve only just started using Chrome, as Firefox has many more plugins.
I’ve noticed Firefox is running much slower now, probably due to the number of plugins. I’m currently using SEO Quake for Chrome, which is alright, but I’m looking forward to trying out different plugins, and eventually being able to switch over to Chrome for good.
Chrome is a great browser and with the added extensions it will start to gain on Firefox. Thank you for a very informative post.

Heinrich
The michromeformats-plugin supports some more microformats (hCard, hCalendar, hReview, hRecipe and geo): https://chrome.google.com/extensions/detail/oalbifknmclbnmjlljdemhjjlkmppjjl
You might be happy to know that SEOQuake is now available within Chrome. Unfortunately Firefox is still the swiss-army knife of plugins and usability but give it another year and hopefully we’ll all be using Chrome (and saving a few hours each day)
