System: Ubuntu 24.04, using Wayland
Firefox Developer 139.0b4
When viewing details using the Firefox Developer DevTools, I am unable to grab panel borders for the purpose of resizing.
I have tried various installs of firefox: snap, flatpak and .deb
It seems like you have to focus devtools before being able to resize it.
If it isn’t the focused window, the cursor is correctly displayed as resizer, but nothing happens.
Can you check if that’s the case for you?
Another question: do you have devtools “docked” inside of your Firefox window, or are they in a dedicated window.
