Mozilla has always created a very good extension development ecosystem for Firefox,
However, every time Mozilla releases a new version of Firefox, developers have to face compatibility issues. The next version of Firefox is 3.1, Mozilla
It promises that Firefox 3.1 is compatible with 90% of the most common extensions. The release of Firefox 3.1 is still in time, but currently, only 28% of the most common extensions are ready.
Long Tail
According to Mozilla's justin scott, 861 of Firefox's 95% extensions account for 5% of the usage, and the other 5000 of the usage is shared by nearly extensions. Currently, the most common extensions are 94% compatible with Firefox 3.0. However, Mozilla's compatibility dashboard shows that only 861 of the 28% most common extensions currently support Firefox 3.1.
95% goals
At present, Mozilla's communication team is trying to contact all Firefox developers to ensure they are ready for Firefox 3.1. The release date of Firefox 3.1 is not accurate yet, But Beta 2 will be released at the end of this month. A beta 3 may be available before the final version is released.
Some extensions have been abandoned by their developers. In the end, Mozilla does not have to achieve the goal of 95%. However, in view of the importance of Firefox and its extended ecosystem, we are happy to see Mozilla's efforts. It is also important for developers to prepare for 3.1, because Firefox users can upgrade quickly after the new version is released.
