Several times in the last few days, I have had missing scrollbars or whole areas of content. In the missions area, the current special mission is the only one that shows (following the trail), the area where the rest of the missions available is blank, and there are no scrollbars. In the planetary actions -> user planetary artifact display, it only show three artifacts, and no scroll bars even though I have many more planetary artifacts in my inventory. I also get missing scrollable area in some of the Ship 'build new' displays; again it only shows the content of the top of the list and no scrollbars. This has happened on two different computers over the last several days.

I've seen this happen in Firefox, works fine for me every time in Chrome.
