Highbrow hangs out in your menubar and has three separate behaviors. You select the one that will best suite your style. If you click on the Highbrow icon in your menubar, then you'll see the three options listed under "Behavior".
Use My Preferred Web Browser
When using this option, your Mac will feel pretty much the same way it did before you installed Highbrow. The only difference is that you can now change your Mac's browser at will from the menubar by selecting a different preferred browser.
Use the Most Recently Used Web Browser
This option really gets Highbrow working for you. Now whenever you switch from one browser to another, your Mac will use the new browser. Thus, if you use Safari, but launch Firefox then your Mac will use Firefox to open links. Switch to Safari again and now your Mac knows to use Safari to open links.
Ask Me Which Browser to Use
When using this option, your Mac will present you with a list of browsers to choose from whenever you click on a link.
Mac OS X v. 10.7 or later

Highbrow says "20 days remaining"
Highbrow runs in a fully functional demonstration mode for 21 days. This message will count down the days until your Highbrow demo expires. Highbrow can be unlocked with a license code available from our store.
When I try to enter my license code, the "OK" button is disabled.
When you purchased Highbrow, Helium Foot (the makers of Highbrow and MercuryMover) e-mailed your license code to you. Try copying and pasting the e-mail address and license code from that e-mail into Highbrow.
I see a message saying: "Your pre-release has expired."
