Some people have reported add-on incompatibilies with Ff3.0, but these seem to be getting resolved; others have had problems that seem to result from not deleting prior Ff versions before installing 3.0. As 3.0 is the current version, and security updates will no doubt be aimed at 3.0, that alone would seem to suggest using 3.0. 3.0 also contains many "under the hood" improvements in memory usage and speed.
Whereof one cannot speak, thereof one should be silent.
