Since you have an extension called "Facemoods", I would guess it has something to do with that extension. Go to Tools > Add-ons > Extensions , locate "Facemoods" and click on it, click either Disable or Uninstall , restart Firefox by clicking Restart Firefox in the Extensions window. Test.

Update Shockwave for Director: your ver. 11.0; current ver. 11.5.7.609 (important security update released 2010-05-11; see http://www.adobe.com/support/security/bulletins/apsb10-12.html) NOTE: this is not the same as Shockwave Flash; this installs the Shockwave Player. SAVE the installer to your hard drive (Desktop is a good place so you can find it). When the download is complete, exit Firefox (File > Exit), locate and double-click in the installer you just downloaded, let the install complete. IMPORTANT: I have found it wise to always restart your system after doing anything with Adobe products. See: Installing Shockwave

I also see in you above posted Troubleshooting info that you or an extension have changed a lot of network.http prefs. You should be careful with making such changes as not all servers support pipelining or like you too make so many simultaneous connections.

I installed facemoods addon and then removed it the standard way from Tools>AddOns... The problem is even after removal the default search that happens from the address bar now points to Start.FaceMoods.Com/... Earlier it was google. So is my browser hijacked as the reviewers of Facemoods addon say? Whatever the case may be, I want the search to default to google and not anything else. So if I type say Oracle in the address bar it should go the Oracle.COM as it was happening before facemoods. Please do help me out in cleaning my Firefox instance.

Renjith The topic of the Original Poster's question is "When I open a new tab, I would like it to open up a blank page, not this site...". Your question is about location bar search. Totally different.
