I am a Quickbooks Online user. Recently, my Firefox browser updated to 72.0.2 (64-bit). Now, after the update, when I attempt to go into my Quickbooks Online account and create a 'new' estimate or invoice, the menus work, but after clicking, nothing opens. I'm not very familiar with web design, but I believe they are Java based menus. If I click one of the links that directs to an outside website, they work fine. I've noticed the same thing on other websites, gemlux marine boat parts is another. Same thing, clicking in a menu does not open the link. Lastly, when shopping on Amazon, if an item has an option (like sizes, colors, etc), and I click on the different size or color, it does not update the item page and price like it normally does. In other words, if I have a $20 item in size SMALL, and hit the drop down to change it to a size LARGE which should be $10 more, the price change does not show in Amazon's price menu. I found that if I click the 'large' in the drop down, leave it, and refresh the page, the page loads with the 'large' size selected, and then prices it correctly. For whatever reason, if I switch to 'privacy' mode, it works fine. I have used all of these websites frequently in the past year, and only in the last week has this started occurring. All of these websites work just fine in Chrome, IE, Edge, etc. I prefer Firefox, so I'd like to get this figured out. It's probably something simple, like a Java setting...but that's over my head. Thanks in advance Shawn
