Unable to open InfoPath form on the browser

Question

Though we have enabled the "Open in the browser" option, some of the users are not able to open the InfoPath for on the browser. It throughs an error message saying,
"This form cannot be opened in the browser. To open this form, use Microsoft InfoPath."
Am I missing any configuration?
I tried the option given in this link as well,

hello Vijayaragavan,
definitely a browser issue, i've seen this A LOT in firefox, where it would open some forms, and throw the same error you got on other times!
-make sure you use IE with sharepoint (check SharePoint browser compatibility) as other browsers would have some feature not functioning as supposed to.
-Add the SharePoint site to trusted sites (Internet options> Security tab> Trusted sites)
-re-publish your form, and make sure the "Enable this form to be filled out by using a browser" is checked.
