Mozilla Firefox removed the status bar / page load progress bar /download status bar from the newest version Firefox 4. I have no idea why they did it, but unfortunately they removed the status bar from Firefox 4. The reason most probably is to give more space to the content of the website rather than toolbars. I used to love it, and it was kind of help that you could determine that how much is the website loaded.
Just after less than 48 hours after the release of Firefox 4 the Mozilla Firefox team released the next version of Firefox for the developers to work on it. Firefox 4.2 alpha 1 is available for download at Firefox Nightly for the developers. So the Firefox team is skipping the version 4.1 and directly jumping on to version Firefox 4.2 is what I see from the nightly latest trunk.
Firefox 4, the new version of Firefox released on 22nd March, got 7.1 million downloads worldwide in 24 hours. So, if someone asks, How many times Firefox 4 was downloaded in 24hours? You got the answer, its 7.1 million. But still wasn’t good enough to break the record of its predecessor Firefox 3. A year ago Firefox 3 came out and made its way to Genesis Book of Record with the highest downloads of 8 million in 24 hours.
