I use these tips to do my web development work.
1. Middle Mouse Button Click On a Link Opens a Tab
(a seperate browser existing in the same window).
Note: Scroll Mouse Button is the Middle Mouse Button..
2. Middle Mouse Button Click on the tab produced in tip #1 will remove the tab..
3. To bookmark all the tabs you have open (as a group),
select "Bookmark all tabs in a folder" option, and save the
bookmarked tab-set where you think it should go.
4. To open a previously defined bookmarked tab-set,
Go to the bookmark location in the bookmark list,
it will appear as a bookmark folder containing bookmarks.
Select "Open in Tabs" at the bottom of the list in that folder.
5. You can put bookmarks or bookmark folders into a folder in bookmarks
called "Bookmarks Toolbar Folder". Or you can drag the icon that appears
next to the url in the address bar unto the blank divider between the
browser page and the address bar.. I use this to keep my favorite links
accessible, without going to the bookmark list..
Reasons to Use Firefox (Almost not even a question for me)
