Refreshing browser does not work after changing CSS

When I change my css and save it, nothing is changing in my browser (Both firefox and safari)

When i reset safari and empty cache i see the changes on my website.

I have never had this problem be开发者_StackOverflow社区fore, does anyone has a solution for me?

Any help would be appreciated.

You could turn off the cache while you develop. In Firefox, insert about:config in the address bar and set:

network.http.use-cache = false
