Can i add a default browser to my form. opening in internet explorer messes with the format

I am not sure I understood your question correctly. Could you please provide more information? Do you wish to change the default browser to open the form? If yes, you need to change it in your system settings. JotForm has no control over it.

Please follow this article to change the default browser: https://www.techadvisor.co.uk/how-to/software/how-change-default-browser-3529331/
