Rated 5 out of 5 stars
Fox Splitter (Split Browser) is so good that without it Firefox is just another browser. I used it constantly, and miss its features terribly in Firefox 4. I have to completely change the way I work! Piro, will you please post here and let all of us know if you (or anyone) will be updating it? If so, I'll revert back to using it with Firefox 3, and try to wait patiently. Thank you.
