No doubt that Firefox 3 and the new places query syntax is going to lead into a lot of new and creative ways of managing the bookmarks saved on your machine. For those unsure what these are they would be your “Recently Bookmarked” or “Recent Tags” selections you see in your bookmarks menu now with Mozilla’s newest browser.
You can think of them as commands for how you wish to pull up your bookmarks.
When creating one, you do it the same way you would create a bookmark. Hit Ctrl+Shift+B to bring up your Library window. Click on Bookmarks Menu (or any other location you would like to create it) then right click where your bookmarks are listed and select “New Bookmark…”.
Tearing Apart Your Places
Now in the new popup window, instead of typing in an address, we are going to type in the places query syntax. For an example:
place:queryType=0&sort=8&maxResults=10
The queryType=0 is telling us to only look at the user’s history and not the bookmarks. 0 would be history, 1 would be bookmarks, and 2 would be both.
The parameter sort= gives us the information on how to organize the results. Here we are using 8 which means to sort by visit count, descending.
Last but not least you have maxResults=10 and it is probably the one you’ll know right off the bat. This number setup here will tell your smart bookmark how many results to show. Setting this number to 0 would give you all the results returned.
Yes, it might still be a little more on the geekier side of things, but play with it some, tear it apart and see what you can come up with.

Need a Firefox add-on that may fuel your creative juices when it comes to blogging? I know you. You said you might almost want to try it again but you just don’t have the time – or you think it is too complicated. 
Bookmarks in Firefox have a very powerful feature that most people don’t know about. Let’s take a look at this:
How can you see some of the Firefox Addons that might not be ready for “prime time” or mass usage yet? Starting a while back, the Mozilla people decided to create a special section for themes and extensions like that. What is the name for this magical place? The Sandbox.
There are a handful of keyboard shortcuts I always use with Firefox. Maybe I’m just becoming lazier as I get older, before Firefox it doesn’t seem like I ever used keyboard combinations to make my way around a program that often.
