WEB2E Runs in any browser. There was an issue in the original JavaScript with supporting the Command Keys for browsers other than IE, but that was resolved with the latest release (8.7). It is documented in the release documents. I think there is a small issue with Safari in supporting F5, but that's Safari for you.
From the release notes.
Command Key Processing (Mouse-click and Key-press)
CA 2E Web Option provides access to command keys on the browser interface using mouse-clicks and pressing keys on the keyboard across the browsers listed below:
■ Internet Explorer 8 and 9 version.
■ Safari 6 or a later version for Mac.
■ Safari 5.1.7 or a later version for Windows.
■ Chrome 24.0 or a later version.
■ Firefox 19.0 or a later version.
Note:
■ Internet Explorer version 8 and 9 are the only officially supported browsers. Check the compatibility matrix on CA 2E Product page for the latest information.
■ Changes have been made to the YMLSSYNRFP syntax file to support Chrome, Firefox, and Safari. For these changes to take effect, regenerate skeletons for functions that you wish to use in these browsers.
This information is also documented in the following documentation deliverables:
■ Web Option User Guide
Here's what they say about Safari
Safari for Windows - F5 Key Behavior
Web Option does not suppress Safari default refresh behavior for F5 key.
During Web Option runtime, if you press the F5 key on the keyboard, a dialog opens with the following message:
“Are you sure you want to send a form again? To reopen this page Safari must resend a form. This might result in duplicate purchases, comments, or other actions.”
We recommend that you do not use the F5 key. However, if it is inadvertently pressed, select the Cancel option in the dialog box.
Frankly, we have been supporting ANY browser using WEB2E for a decade or more in our implementation. It was just a matter of making the (small amount of) javascript work across browsers. It really wasn't a huge technical hurdle, and anyone that wants to do anything more than out of the box WEB2E should have the technical skills to have been able to achieve it without needing CA to do what they did for 8.7, but I digress.
Now, that CA would tell you that they are not supporting other browsers, well, all I can say is you must have go the wrong support person...well, other than that's what their documentation states. I think that's a little overboard, and as I have already noted, we support all browsers through our implementation...
