Firefox X close button on sidebar is a bit awkward

francescoMeninH — Mon, 15 Jun 2026 08:00:46 GMT

I recently switched back from Edge to Firefox due to a number of issues with profile syncing, and I love the vertical tabs option because of how 16:9 screen estate is designed.

One issue I get with using it in Firefox is that I sometimes misclick the X button and close the tab instead of selecting it, so I was wondering if there is a way to disable it by default (and only use either the middle button or a keyboard shortcut option).

It may be a very small change, but it has happened so many times in the last few weeks I am starting to worry that I am not able to use a mouse anymore...
