Hello. I have been trying to download an iCalendar ics file from a website which has my schedule. Once i click "export to calendar" option on the website, the firefox download manager starts up and download the calendar for me with an ics extension. If i try to open the file it says "file is corrupted or not working". I have downloaded the same file in google chrome and microsoft edge browser and the ics file opens up. It does not however in firefox. Is there a way to download ics files in firefox as firefox is my default browswer and i do not wish to use thunderbird or any other browser. Thank you
