12. Hack Firefox's new Zoom feature
Firefox 3 adds some very nice capabilities to Zoom, which now magnifies images as well as text. But if it doesn't do everything you want it to, or you don't like some of the features, they can be hacked. Here's how to do it with about:config.
You can zoom in and out of pages with Firefox using the Ctrl + and Ctrl - combinations, or by selecting View --> Zoom. When you zoom pages in a Web domain (such as computerworld.com), the next time you visit any page in that domain, Firefox 3 will remember your zoom level and display it at that level.
You may, however, prefer that Firefox always display a page at a normal zoom, no matter how you displayed it the last time you visited. If so, you can change the following setting from true to false by double-clicking it in about:config: browser.zoom.siteSpecific.
Firefox 3 adds some very nice new capabilities to its Bookmarks Library, which you access via Bookmarks --> Organize Bookmarks, or by pressing Ctrl-Shift-B.
One big change is the use of tags, which makes it easier to find and organize bookmarks. When you bookmark a site, you can add tags to the bookmark, by typing the tags into the Tag box. If you want to add multiple tags, separate them with commas.
To find sites that match your tags, open the Bookmarks Library, click Tags in the left-hand column to see all of your tags, then select any tag. You'll see a list of all the sites with those tags.
The new Bookmarks Library (accessed by clicking on the Bookmarks menu and selecting Organize Bookmarks...) has a nifty trick for you: the ability to create Smart Bookmark Folders. When you add bookmarks, they can automatically be routed into the proper Smart Bookmark Folders, without you telling them where they need to go. That way, sites can show up simultaneously in multiple folders. And if at any point you want to reorganize your bookmarks, you don't have to move the bookmarks around. Just redefine the Smart Bookmark Folders, and the bookmarks will be displayed in their new locations.
One interesting note about Smart Bookmark Folders: Not only bookmarks will show up in them, but also sites that you've recently visited.
To create a Smart Bookmarks Folder, you create a search, and then save it. All sites that match your search will automatically show up in that folder:
1. In the Bookmarks Library, search for a term or combination of terms by typing them into the box on the upper-right portion of the screen. Press Enter.
2. Click the Save button. A dialog box appears, asking you to name the search. Give it a descriptive name and click OK.
3. The new folder will appear toward the bottom of the navigation on the left-hand side of the Library window. Click it to see bookmarks that match the search term, as well as sites you've visited that include the term in the URL or description.
