Isn't a little premature to dump all your past purchases on the strength of a beta release of a future version not working with cutting edge alpha / beta versions of web browsers?
The current version (2.3.6) is very stable and that's the supported version. We know that IP.Board 3.0.0 Beta has issues; that's the very reason we ask you to test it. We would not ask you to test it if you were going to make a decision whether to continue using IPS products on the strength of it.
Now, does the edit button work for you in FF 3.0.7? Forget 3.1 Beta 3.5 beta, etc - just use the current stable FF release and let us know. If it does not, then file a bug report. That's all we ask.
Lee, Sunrise was telling you that the option to include the full reply in a topic subscription notification has been in IP.Board for years, since 2.1 if I remember correctly. This feature is also in IP.Board 3.0.0 so there is no need for a mod, etc.
