I heard from so many people that Firefox was an 'awesome' browser, but when I installed it I was faced with the Awesome bar, which exposed sensitive bookmarks to visitors on my computer (and potentially to Mozillla Corporation). As I am a private person, I was not happy about this at all so I went back to using Safari.
However, the new Safari 4 has crushed my belief in almighty Apple (it has eliminated the 'stop loading' and 'refresh' buttons, and it blocks users from saving free movie clips from the internet, even if the site allows you do do this, as shown by Firefox) and so I tried Firefox again. Thanks to this add-on, I am in the Firefox camp and look forward to Firefox 3.5, which will include the feature to remove bookmarks from the Awesome bar.
As a Mac user, I needed to restart my computer to get the add-on to start working. Restarting Firefox alone did not do the job.
