I'm using Firefox 67 (64-bit) on Windows 10. The Create link and Change language (which appears in a code block) buttons don't work. They're supposed to open dropdown menu of sorts, but that doesn't appear, or only very briefly, and instead the floating toolbar disappears. Ctrl + K still works to create a link, but I'm not aware of any such keyboard language to change the language for syntax highlighting a code block. I've tried this both with and without Content Blocking and uBlock Origin, and the issue remains. This functionality works perfectly in Chrome.
