When I open DevTools on AO3, FFN, or Webnovel, it defaults to the debugger tab, and I would like to have it not do that.
Any suggestions that might work are welcome.
How are you opening DevTools?
There’s no configuration by origin/page, when you open DevTools it opens with the latest selected panel.
If you use the “Inspect” context menu, it should always open the inspector.
Then you have panel-specific shortcut: All keyboard shortcuts — Firefox Source Docs documentation
