What is a cache you may be asking??
Your internet browser saves some pages to make it load faster.
Well newschoolers changed, so what's in your cache is incorrect, it's confusing.
So lets clear that shit.
I took some time to show this, cause it dramatically sped up NS for me at least, I will be covering Firefox, Opera, IE 7, and Safari, all for windows
Click Tools, or CTRL + SHIFT + DELETE.
Should come to this screen
I checked only the cache box, but clearing cookies helps too. Just click done when your set
Pretty simple here, CTRL + F12
Or Click Preferences here
Now Click on the Advanced tab, then History on the Left side .
Click empty now and your set.
CTRL + ALT + E... or click it like in the pic
A window pops up, say yes to empty.
4. Internet Explorer 7
Tools- Internet options
Now click on Delete under browsing history
Now a new window should pop up, Temporary internet files would be cache on IE7 so go ahead and clear that, click yes when a window pops.
Now IE6 , Tools, internet options, clear Temporary internet files.
hope this helps!
