A Firefox update to version 1.0.3 is in the works according to a post on MozillaZine. It includes a fix for the JavaScript vulnerability that GeekCoffee posted on earlier this week. The MozillaZine post follows below:

"Asa Dotzler has announced the availability of a fifth set of Mozilla Firefox 1.0.3 release candidates. We reported on the forthcoming Firefox 1.0.3 and the first three release candidates two days ago. Late on Tuesday, another release candidate was made available with a security change that caused many extensions to stop working. This fifth set of release candidates should not break anywhere near as many extensions. Any feedback should be sent to Asa."

"As many people have asked, we would like to inform readers that the JavaScript engine memory heap disclosure bug will be fixed in Firefox 1.0.3. There will also be a Mozilla 1.7.7 update and possibly a Camino 0.8.4 release to fix this vulnerability in other Mozilla products."

Currently, there are builds of the upcoming update available to be tried and tested. There has been no official word on when the update will be released, however, GeekCoffee expects it to be available soon, considering Mozilla's past track record.

Figures released this week from web analytics company OneStat show Firefox gaining significant ground in market share to almost 13% worldwide, and 16% in the United states. The numbers also show that usage of Microsoft's Internet Explorer (including the new version 7) has dropped by 2.12% in the past two months.

The trends are sure to keep going in this direction if Firefox's 2.0 release goes well and relatively bug-free.
