can't change default browser to Firefox

i just heard the news about IE and now i want to change my default browser to Firefox and now i can't change it because i tried to open up a favorite from the start menu and it opening in IE and when i went to internet options it still showed IE as my default browser i am using the beta version of Firefox 29 i looked at the firefox options and clicked make default it was a no go

tried it like this everything is still opening through Internet Explorer, any other suggestions, should i try removing Firefox and then re-installing it through Internet Explorer

if you are on WinXP:

Click start, then click "Set program Access and defaults".

Click custom, Click the arrow on the left of custom. The first thing you will see is "Choose a default Web browser". Click Firefox and that is it.

If you are on Windows 7, Try @Brink's Instructions again. if that does not work, your windows os might be malfunctioning.

i finally fixed, but now i am having another problem with FireFox, Flash is not working at all on CBS's website when i try to play a video i get the message saying the plugin become unresponsive and i get the option of stopping the plug-in or continue waiting for it it does this everytime and it is becoming frustrating does anybody know how to fix this please help i hate missing my shows

plugin lock up? try restarting Firefox. and/or update flash player.

first of all you are not an expert i would much prefer for Brink or Thrashzone to help me because none of these suggestions are going to work

i tried it and it still didn't work still got an error i finally did say screw it and went to chrome and it woroed fine, i tell you ever since i switched to firefox its been nothing but a nightmare
