The Mozilla Foundation's main site -- mozilla.org -- and home of its Firefox browser and Thunderbird e-mail client, suffered intermittent performance problems staring Sunday and continuing Monday, a Web tracking firm said.
According to U.K.-based Netcraft, mozilla.org, which runs off the Apache Web server 2.0.52 software under Red Hat's distribution of Linux, took as long as 10 seconds to load for some users Sunday and Monday. Approximately 15 percent of the requests for the page from mid-day Sunday through mid-day Monday, said Netcraft, failed entirely.
"Version 1.0.6 of Firefox was released last week, but it's not clear whether the update contributed to the sluggish performance for the site," Netcraft said in a statement.
The last time the site was bogged down by large numbers of download requests was when Firefox launched its 1.0 edition in November 2004.
Mozilla did not immediately respond to a request for comment on the reason(s) behind the site problems.
A little more than a week ago, Mozilla acknowledged that its SpreadFirefox.com site had been hacked, and that it had taken the site offline for several days to investigate the intrusion.
SpreadFirefox returned to normal operation last week, but Mozilla representatives urged all registered users to change their passwords.
