Google Chrome was great – but for some reason, a number of web sites I use almost daily (such as my Internet bank and pbwiki.com) did not function well with it. In addition, I have had some unexplained bluescreens since I started using it (having 30 windows open at the same time may have had something to do with that.) Lastly, a number of plugins, most importantly Zotero, are not available for Chrome.
So it is back to Firefox again. Still some issues, and I will miss the search-like interface of Chrome (write "af", hit enter, and it takes you to aftenposten.no). Still, ideas (and code) of Chrome is open source, so I expect to see a number of Chrome features in Firefox fairly soon – here is a preview of what is to come.
