Try to clear the cache and remove cookies only from websites that cause problems.

"Clear the Cache":

• Firefox/Tools > Options > Advanced > Network > Cached Web Content: "Clear Now"

"Remove Cookies" from sites causing problems:

• Firefox/Tools > Options > Privacy > "Use custom settings for history" > Cookies: "Show Cookies"

You can run this code in the Web Console (Firefox menu button or Tools > Web Developer) to clear localStorage for the domain in the current tab.

var P=localStorage,L=P.length,i;for(i=L-1;i>=0;i--){K=P.key(i);P.removeItem(K)}

Evaluating localStorage should give length:0

Note that you may have to type a specific phrase to allow pasting in the Web Console.
