FireFox and IE not adding file extension

[johnhoysa]

Having an issue where IE9 and FireFox download the file but do not add the file extension. Webkit browsers seem to handle this just fine. Using EE 2.7.2.

Thanks for a great plugin!

Added to line 70 - header( 'Content-Disposition: attachment; filename="MyName.ics"' );

Forced the file to always be named the samething but also forced the file extension to be added and solved the issue.

EDIT
Made it a little more dynamic with the help of a co-worker.
$filename = ee()->TMPL->fetch_param('filename');
if (empty($filename)) $filename = 'MyName.ics';
header( 'Content-Disposition: attachment; filename="'.$filename.'"' );

Then in my template
{exp:easy_ical:calendar timezone="Central/Austin" name="My Name Here" filename="{url_title}.ics"}

Everything is working exactly as I want it to now.
