Ubuntu 8.04 and Firefox 3 Beta 5

[Ioannis Vranos]

I have some concerns about Ubuntu 8.04 and Firefox 3 Beta 5. I have read
that Firefox 3 Betas are unstable. Why this Beta was chosen to be
included in Ubuntu 8.04 instead of the stable version? Are there any
other Betas included in Ubuntu 8.04? Has anyone any experience on
Firefox 3 Beta 5 under Ubuntu 8.04?

The Firefox 3 Beta 5 mainly stops me from upgrading to Ubuntu 8.04.
