It looks like a popular question but it's just the opposite.
When I visit a site in Firefox 15 I have two different behaviours when:
- Pressing enter in the address bar
- Pressing F5 or the refresh button
If I look in the network console I can see that F5 does a lot more requests, most of them about cached resources and with a 304-Not Modified answer.
Is there's any shortcut to make a quick refresh? Just like pressing enter on the address bar.
