Firefox Tab Height under Windows 8 is double sized.


The Tab on my browser is double sized under Windows 8. I have already searched the forums for a solution and none worked.

Already tried: 1. Safe mode 2. Create new Profile 3. Reinstalled with NO extensions 4. Cleaned out everything entry in appdata/programdata/registry

After everything double sized tab persists.

So I am led to believe that this is some new setting for Firefox where it detects an unknown 'Tablet' mode and sets the default theme as having double sized tabs. -- And just FYI -- I am NOT using a touchscreen. So whatever it is detecting, it is faulty. If you are going to put this in as an option, please add an option to DISABLE it.

When I change to another theme, such as Mx3, it does fix the double sized.

I'm already running v8.1 ( in Device Manager), so that's not it for me. I could try uninstalling/reinstalling them though.

You don't need to edit registry settings to disable the charms bar edge swipe, there's a tick in Mouse Settings "Enable Edge Swipes".

I've decided to go for leaving the "Touch Keyboard and Handwriting Panel Service" disabled as I don't have a touch screen or handwriting panel.

I'm not sure what a Touch Keyboard is? And disabling the service has no effect on multi-touch on my trackpad anyway (controlled by Synaptics).

I'm guessing disabling gestures.enable_single_finger_input disables Firefox's touch trackpad support, not that it works for me and it seems to be for Mac only.

@ ardofy: The tabs are bigger as it think you've got a touch screen and is making it easier for you to press them. I imagine anyway.

I was able to get something to work based on zoao's userChrome.css content. It involved adding a min-height attribute. Try this:

 .tabbrowser-tabs *|tab {
   height: 20px !important;
   min-height: 20px !important;

Seems to work nicely on my brand new Surface Pro.

Well I spoke too soon. It fixed my tab issue, and now they look normal, but now there is no touch functionality in Firefox. I use my finger to try and scroll down a web page or pinch/zoom and it just selects text as if I'm using the left button on my mouse and dragging.
