I've been thinking about how scrolling a Workboard page, like this one and that one, is experienced in various browsers. Actually, I intend to describe in one task how the Workboard pages are tested on other browsers. However, I figured that describing the experiences takes a lot more words and formatting than I thought. Therefore, I think figured using this task as the parent task for child tasks about the pages in individual browsers would be more efficient than creating one huge task about various browsers.

EDIT: However, I tested Firefox 59 and found out that Workboard pages don't have scrolling issues, aside from not being able to click the scroll wheel on the open white area and grey left panel. The scrolling experience seems similar to those of Chrome and Opera, but I can only horizontally scroll a Workboard page, and I can only vertically scroll any column. Also, no (minor?) vertical scrolling issues, like ones experienced by Chrome and Opera. Overall, much much better than using other browsers to scroll a Workboard page.
