MSN Toolbar Suite containing Windows Desktop Search is gaining momentum. Late last week they have introduced in the suite a New! Tabbed Browsing capability to IE. Interesting stuff. Currently I use Avant Browser (based on IE Engine) as my browser. I am going to use MSN Toolbar for some time and if its Tabs feature is fast, stable and convenient, I will certainly switch to it.
Post your experiences on tabbed browsing in IE below in the comments section. You can read my earlier blog on Desktop Search posted here.
