I'm going with the newest version of Firefox Developer, 121.0b9 (64-bit) currently, and have noticed that the "No proxy for" frame in "Connection Settings" became one-line display only several months ago.
This was previously occupying certain height but now is one-line only. I have to manually change the cursor to get other records shown in the frame, which is annoying because I'm unable to locate the certain record quickly. Maybe it's a good idea to make it growing dynamically while fitting the content.
