A second browser window will not open and then closing the 1st window firefox will restart. Taskmgr shows it still running, it will not restart until I end the process in taskmgr.

Question

I open the browser and close it every thing is fine. I open the browser and then attempt to open a second browser window, it will not open. Now because I've attempted to open a second browser window firefox will not restart after closing the open window. Until I've shut it down in the taskmgr. This just started the other day and I have removed the only update I made that was "flash" and I removed the 64 bit version of firefox.

Answer 1

Win 7 with iTunes installed - I was also having problems with that.
"netsh winsock reset" at the command prompt resolved all issues and Firefox launched normally.
Check to see if Winsock is corrupted. May prevent FF from communicating with the web and consequently fails to launch properly - for my situation was not a firewall or antivirus block!

Click Start, and in Start Search, type cmd.
Right-click the cmd entry that appears in the search results, and then click Run as administrator. If you are prompted for an administrator password or for a confirmation, type the password, or click Continue.
At the command prompt, type the following, and then press ENTER:
netsh winsock reset
Then, you should see the following message:
Successfully reset the Winsock Catalog. You must restart the computer in order to complete the reset.
Restart the computer.
Note If you receive an “Access Denied” error message instead of the message that is mentioned in step 3, the command prompt was not correctly elevated. In this case, close the Command Prompt window, and repeat steps 1 through 3. Make sure that you correctly implement step 2.
