Odoo is the world's easiest all-in-one management software. It includes hundreds of business apps:
CRM | e-Commerce | Accounting | Inventory | PoS | Project management | MRP | etc.
All the browsers have there on little and sometimes big problems. They are not all conforming to the standards which are developing rapidly. I have seen different results with OpenERP with different browsers.
What is the recommended browser from which we can expect the best results?
I can imagin it is different for OpenERP versions.
I would say clearly chrome for v6.1. For v7.0 probably too.
It seems OpenERP developper and support teams are mainly doing there tests on chrome, chromium and firefox. Certainly because most of them uses Ubuntu being in the Open Source spirit and those browser are more accessible on it.
On v6.1 we had some issues with Firefox, it's much more stable on v7.0
For other browsers I haven't experienced much of it. However, you can track errors on openerp-web bug tracking You will see that users makes bug reports for specific browsers and OpenERP is constantly improved.
Thought, I can only suggest to avoid Internet Explorer but this is mainly my opinion.
