Problem with the extenion after updating Firefox 55

Hello all,

I recently upgraded my Firefox browser from version 54 to version 55 and now have have been having an issue with the browser add-on. when I click on th extension, I can log on just fine and the dialog part of the add-on pops up. But when I try to click on any of the options, all I get is a blank screen. I can click on My Vault and it opens up the web portion just fine but I use the browser extension ALLOT more than I use the web page. I also uninstalled the add-on and reinstalled it (and restarted the browser) and it still doesn`t work. Is there a fix for this or is this a problem with Firefox/ If anyone has a solution, any help would be greatfull!

Thanks

I didn't find the right solution from the internet.
