I don’t recall there being anything obscure about setting up Firefox or using it, and I completely prefer the way Firefox handles Bookmarks to the way IE does it; working with them is done in a whole separate window called the Library that looks a lot like the Windows Explorer used to browse files on your computer. The left pane displays browser History, Tags and Bookmarks with the Bookmarks appearing in a user-defined ‘folder’ structure, and the right pane displays the actual Bookmarks in the currently-highlighted folder. If you’ve used Windows for any length of time at all, the Firefox “Library” window will be instantly usable for you.
I also like that Firefox allows you the use of “tags” with Bookmarks; extra terms you can associate with any Bookmark to make it more easily found in the future. Say, for instance, you have a half-dozen websites you go to frequently for genealogical research, you might put “genealogy” as a tag on each of those Bookmarks. Having done so, at any point you wanted to access one of those sites, you could simply begin typing “genealogy” in the Address Bar, Firefox would pick up that the term was a Tag, and present you a drop-down list of the six websites you’d tagged with that term. More than one tag is allowed per Bookmark, so you could have one website, say, that you tagged “genealogy; records; military” and a different site that you tagged “genealogy; records; Quakers” and so forth.
If it’s something you’ve an interest in taking a look into, Firefox and IE WILL live together in peace on your computer, and you can take time to play with Firefox while you continue using IE as your default browser. That would give you all the time you could want to become familiar with Firefox, and actually make a sensible determination as to whether you find it easier to use, or not.
To make Firefox “play nice” the only thing you MUST do is click “Firefox > Options > Options” pick “Advanced” and go to the bottom of the “General” tab. There you will see a checkbox next to the sentence “Always check to see if Firefox is the default browser on startup”. Simply make sure that box is UNchecked, and Firefox will not “fight” with IE over Alpha Browser status.
In reality both browsers want to be default. The check box in IE is found in 'internet options' on the 'programs' tab...
If you decide you like Firefox, select it as default and turn off that option in IE (along with 'tell me IE isn't default' or however is is phrased to avoid incessant nagging.)
Also be advised that there are still some (although no where near as many as several years ago) web sites that only display properly in IE*. Firefox has a really neat add-on (extension) called 'IE Tab' that allows you to change to IE within the Firefox tab to view these obstinate pages... ;-)
*Usually the result of the webpage designer being lazy and using MS Frontpage to lay out their web pages... (MS software operates with attitude.. "You will do it OUR way..")
