Whenever Adobe Acrobat opens in the browser, the "Welcome to use Acrobat" sidebar remains on the left side, which annoyingly takes up space and must be closed separately. Every single time!

Also, Chrome's address bar is cluttered with "chrome-extension://efaidnbmnnibpcajpcglclefindmkaj/" at the beginning of the URL, so copying the link is tricky.

It's shocking how such usability disasters have been left in the product.
