When clicking on the wrenches in Style Manager, sometimes the class name disappears when I click on the check box. Am I accidentally deleting the class, since it seems that the X button is hidden by the scrollbar?
Thanks so much for reporting this. Designer support in Firefox is still experimental, but I’m happy to share this with our team so we can take a closer look!
Would you be able to use a tool like Cloud App to provide me with a short video about what you’re seeing?
Looking forward to hearing back so we can tackle this issue!
It seems that I was acciedntly double-clicking the took icon. In between, that icon changed into a delete icon, so my second click registered as a delete. Tricky to use such small buttons, though I understand you want to make the most of what room you have. Maybe look into improving the UK?
