Icons do not appear in the Collaborate interface when in older versions of Firefox.

Interface icons such as the hamburger menu icon are not visible, but still functioning when the area they would normally occupy is clicked.

Update Firefox browser version or use a different browser, such as Chrome.

Blackboard won't fix this issue due to it being an out of date version of Firefox on University Managed Desktops. Update browser version or use a different browser.
