All kinds of problems with ZOHO Business

I was wondering is Zoho compatible with Flock?

I'm having all kinds of issues with Zoho in Flock and Mozilla Firefox as well.

Email:

1) Email has very slow reaction time when clicking on certain actions like: fetching mail, move emails to folders.
2) Labels that I remove from emails will re appear for no reason at all. And double up with the newly assigned label.
3) Adding folders is very slow.

Adding Applications:

1) I can't reorder the applications I add or even the once already there. (not in control panel or dashboard)
2) I have deleted certain applications but are still showing in the list of applications on my dashboard (but not in the control panel app list)
3) Request: Possibility of opening applications in tabs on dashboard. (like this forum does) Would be great.

Notebook:

1) Very slow responds
2) Notebook functionality freezes up a lot while trying to add items.

General issues:

1) Really the whole Zoho system for some reason tries to freeze up on me a lot. I don't know if this has to do with any settings in my browser or if there are still bugs in the program.

Either way please help me out. I really would love this to work because I do like the complete concept but it would greatly in prove satisfaction if it would not freeze up on me and if the above points could be resolved some how.

Thanks for your responds
