Having tried out Google Chrome in its semi-native version (Windows 7 beta in VMWare Fusion on my Mac) I decided a few weeks ago to try out the Mac dev version. It installed fine and is fast and stable and has worked well for most although not all web sites. Today I decided to get the Linux version and after checking for a package with Synaptic - not there, as I suspected would be the case - I found a direct download at Google of a .deb file. It was one of the many cases of a Linux install being just as easy as in OS X: click to download, enter the system password when it's finished, click a few buttons and it appeared in my Applications->Internet menu. So far it seems fine (unlike Firefox, it works with the Last.fm web site) and it's nice to have yet another browser to choose from.
The one problem was in importing bookmarks. Today I also finally got around to installing Xmarks and signing up so I could merge and synchronize my bookmarks on my two personal machines. That eventually worked out fine, but I wasn't able to find where bookmarks were stored on my Jaunty machine. Both bookmarks.html files I found included only the handful of default bookmarks that came with the basic installation. I still have no idea where they are, but I eventually learned that by going into the Firefox menus in Bookmarks->Organize bookmarks... it's possible to export them as a file and then import them into Chrome.
I'm not giving up Firefox as my default browser, but Chrome is an attractive fast alternative.
