I'm using Firefox Developer Edition 132.0b2 (64-bit) and noticed that the only way to open a new tab is to click on the pancake icon and select new tab. The "+" icon in the tab bar is missing.

I also noticed that there is no way to reload the page (especially doing a hard reload). This is a major issue when making updates to websites and wanting to see those edit. Clicking in the address bar and then on enter will reload the page, but does not do a hard reload, so the cached version of the page is displayed, not the updates.
