Salesforce Browser Support and Configuration Doc
Mar 18, 2009We recently released a new document listing the official browsers that Salesforce supports. As noted previously in the User Experience blog, Internet Explorer 6.0 is still supported, but we recommend Firefox 3.0 for the best performance. If you want to continue using IE, we strongly recommend that you upgrade to IE 7.0 and apply all Microsoft® hotfixes. IE 7.0 is faster, more reliable, and better supported than IE 6.0. Salesforce also supports Safari 3 for both Mac and Windows platforms.
The new Browser Support and Configuration tip sheet also includes configuration recommendations to maximize browser performance for both Firefox and IE.
As new browsers and versions are supported, we'll update the Browser Support and Configuration tip sheet with all the details.

What is the plan and schedule for supporting Internet Explorer 8?

Please Salesforce, if you're going to push Firefox as the recommended client browser, reimplement your Mail Merge so it works in it. Until you do that it's entirely unrealistic to expect people to use Firefox for their day to day usage, and switch to Firefox to produce letters, contracts, quotes, etc.

@Ollie C - Salesforce already supports mail merge from any browser using the "Extended Mail Merge" feature. You need to contact Customer Support to have it enabled, but once activated, you can use mail merge capabilities using any of our supported browsers.
See the online help for more information:
https://na1.salesforce.com/help/doc/user_ed.jsp?section=Organization_Setup&loc=help&target=customize_ui_settings.htm
(Note will need to change the "na1" portion of the URL above with whatever Salesforce instance your organization resides. The instance is the first set of letters after https:// when you log into the service.)

We are piloting with Firefox (as our policy at the moment is IE) for salesforce.com use.
After some research we did some tweaking to:
1. Double browsing speed using FF (this really works :-)
2. View alt tags on images (on mouse- over see the 'help' text)
3. Be able to automatically windows authentication for Intranet sites (you will see a login screen otherwise)
Below the resources to make these changes in FF:
1. http://www.pctipsbox.com/how-to-double-firefox-speed/
In addition, also set the network.http.pipelining.ssl to true
2. https://addons.mozilla.org/en-US/firefox/addon/1933
3. Go to: about:config in FF and look for: network.automatic-ntlm-auth.trusted-uris. Set the value to the intranet sites, for multiple values, seperate with comma's. Example value: your.intranet1.com, your.intranet2.com, your.intranet3.com
