Enpass "script" preventing pages to load - firefox extension

[david]

I can't give you the url since it's in our bank/booking service online and you need an account to be able to access. But what happens is that whenever we try to fill in a form on the page (which we do thousands of times per week when doing bookkeeping), enpass, i guess, is trying to intercept the input to see if it's a username/password or whatever (maybe?). Problem is that whenever it does whatever it does, the page freezes for a few moments and a popup in the top of the screen says "a script in the extension Enpass is preventing the page to load" And we can choose to deactivate it temporarily or stop the script. But it just keeps returning and the only way to prevent it is to go to the firefox extensions and dectivate enpass completely. 

Is there any way to get around this? Can I black-list a url from Enpass or something so it never tries to collect any form inputs from a specific url or what do I do?
