I needed one font...then i found 24000. I installed all of them. My computer started to take minutes to do everything. So ...
How do i browse all fonts without crashing everything..not that i think its a good idea.
You don't say what OS you're on. I have nothing to offer for Windows but...
For OS X
Font Explorer X is a fantastic app. If you're running an older OS (10.6, I believe) you can still use the old free version, if you can find it somewhere. The new paid one is excellent though.
If you just want to see what the fonts look like without any special software, OS X's quick view feature will do the trick (I'm sure Windows has something similar).
