Tab bar is ~6px bigger with multiple tabs than it is with only one tab

Example:

I open a new FF window. One tab is open. I open a second tab. The tab bar now gains approx. 6 pixels in height. It shrinks back if I reduce the number of tabs I have open to 1.

This is annoying. Is there anything that can be done about it?

I've already tried fiddling with userChrome.css based on a Google search, but since I don't know what I'm doing I haven't had any luck in stopping this from happening.

Chosen solution

Is there a close button appearing on the first and second tab when that happens?

Set the pref browser.tabs.closeWindowWithLastTab to false on the about:config page to prevent closing the last tab from closing the browser and make a close button appear if only one tab is open.

You can open about: pages via the location bar like you open a website.

The close-button is present even if only one tab is open thanks to the "Last tab close button" addon which I have installed.

Speaking of add-ons... I found out the problem disappears if I disable the Oxygen KDE add-on I have installed (probably should have tried disabling all add-ons first.... sorry!). However, the issue may still stand: I noticed that even without add-ons, if I close the last tab (with your setting in place), the FF tab bar shrinks by those same 6px. So I think what I'm needing is a way to make a tab bar with 0 open tabs the same height as a tab bar with 1+ open tab. I'm fairly confident that such a setting would automatically resolve the problem I turn out to be having with the Oxygen KDE add-on as well.

Either way, it's probably best to take this issue up with the Oxygen KDE devs - correct? I'm terribly sorry if I've wasted your time.

Yeah, it was the style that came with the extension. I switched to a Persona style and the problem is resolved :-)

Thanks for helping me out and sorry if I've wasted any of your time.
