Besides writing tips, I also post on the CRM TechNet wiki. I recently wrote a post listing the optimal settings for Internet Explorer. This is something I frequently get asked for. Even if you use a different browser, if you use Microsoft Dynamics CRM for Outlook, when you access records, you will still be using Internet Explorer to render the forms.
Read the list here. Have anything to add to the list? If you have a Microsoft account, you can edit the wiki!
