1) I highly recommend Firefox for web browsing. If you’re on a PC and you’re using Internet Explorer, baby Jesus is weeping. End of story. Safarion Mac is ok too. But for the purpose of this post we’ll be looking at Firefox.
2) Firefox is very customizable. Themes, extensions, and plugins that make your browsing experience your own.
One thing I love about Firefox is the Bookmarks Toolbar.
To save time and space, you can add the sites you’ve recently visited to your bookmarks. When you place them in the Bookmarks Toolbar they show up across the top of your browser right under the nav buttons and address (location) bar.

A quick and easy tip to save even more space in this toolbar is to delete the name of the bookmark in the properties of said bookmark. When you do that it shows only the favicon (icon) for each bookmark taking up a fraction of the space it would if you leave the name in the properties.
To do that:
Right-click (ctrl-click) on the bookmark icon in the tool bar.

Select Properties.

Hi-light and then delete the name.

If you’re like me and you really value browser viewing real estate you can even tweak your userChrome.css file to have the Boomarks Toolbar be hidden unless you mouse over the area where it normally lives. Be warned though whenever you mouse over that area it shifts your browser window down about 3/4 of an inch and then back up again when you mouse off of it. If you have motion sickness it might send you over the edge.
To “hide” your Bookmarks Toolbar and make it mouseover-able:
Install ChromEdit Plus on your Firefox browser.
Restart Firefox.
Open ChromEdit by selecting Tools > ChromEdit Plus > ChromEdit.

Copy and paste this code at the very bottom of the userChrome.css file:
#PersonalToolbar {display: none;}
#navigator-toolbox:hover > #PersonalToolbar {display: -moz-box;}

Restart Firefox.
These are tips that seasoned browser hackers can do in their sleep, but I thought it would be good to share a tip that helps save time and space when I’m doing my daily browsing.
Sites that I include in my Bookmarks Toolbar:
Occasionally, I go through and prune my bookmarks, deleting the ones that I might have added because I thought the site was cool/helpful/informative at the time, but notice that I don’t visit regularly. I’ll move those bookmarks to another folder.
Hope these tips are helpful.
