In yesterday’s Tip of the day: Find a file, jump to its folder, I forgot to mention Firefox, which also has a hidden Open Containing Folder menu.
After you download a file in Firefox, you see the Downloads dialog box.
The two visible commands give you a chance to open the file immediately (handy if you want to install a download right away) or remove it from the list of downloads. But right-click and you get two extra choices.
The Open Containing Folder option opens Windows Explorer in the folder where you saved the file. The Properties dialog box tells you where the file came from and where you saved it.
Good stuff to know!

Great set of tips, thanks Ed! By the way, is that a Firefox skin, or an XP visual style (or maybe a WindowBlinds skin)? I like it – subtle and understated.
Jason, I was wondering if anyone would notice! That’s actually the default Aero style from Windows Vista.
