Try not disabling Firefox. I just checked my "about" WindowBlinds settings and your graphics rating & card is a bit better than mine. And everything works fine on mine. I can only think it might have something to do with preventing WindowBlinds from skinning Firefox which I use as well. If not, I'm sure someone from support will be along shortly with a better answer.

The poster is from Sweden, could this be a problem with the language version of the OS? 

Lazionord...

I seem to notice that you have your tabs on top on Firefox. I always have my tabs on bottom on Firefox and my Windowblinds work just fine. My buttons are never blanked out. Try that and see what happens. I think that should fix your problem with it. Firefox is all I'll use as I hate Internet Explorer.

Tried it out just now, same problem, couldn't even open up Firefox. It's probably another thing than the design layout of Firefox. Hope I find a solution so I can use WindowBlinds.

Just finished installing 17.0.1 and my WB is still displaying properly. As you can see, I have Arsenic by danilloOc applied.

Oh wow! That sucks dude, I feel you. If you haven't done so already, shoot support@stardock.com an email and make reference to this post. Neil did post on it and He's the MAN when it comes to WB's. It may be something quirky and may have a solution. Just hang tight and give Stardock the opportunity to make things right...

Edited:unrelated problem

Could it possible be that my WindowBlinds and Firefox are installed on two different partitions or disk for that matter?

I made a as much as a clean install I could, even installed FF on same partition as WB. Same issues persists, for some styles if the browser is open it applies correctly, but then again FF don't open after a restart.

I have done everything possible to be as clean as possible.

Some skins work just fine if FF is open and I apply them, but when I close FF and start it again, it never opens, FF just runs as a process in taskbar but will not display.

Can Stardock staff acknowledge my issue and help me solve it, I made a ticket three days ago, yet no answer.

i have the same problem, but with some of the skins,

for instance , if you choose the "windows aero" skin firefox is skinned correctly, using its own skin engine

but if you choose other skin, the skin overwrites firefox's skin

so you have to choose windows aero skin, then apply the changes, close firefox , open firefox

then apply any other skin, and again close firefox , open firefox, it should work

but the minimize, restore and close buttons are still skinned, even if firefox is in the exclusion list

so basically i need firefox won't be skinned by any skin, because it has its own skin engine

There is a solution I believe. I just noticed the orange tab at the top of your pic, this is what is preventing your top from skinning I believe. If you right click on it or somewhere near it, a pop up should appear or somehow a drop down menu allows you to disable that menu bar. Then the tabs appear. Sorry so vague , but I had that problem and fixed it, then ended up with an older version for different reasons. Firefoxe site could help disable that menu also. Goodliuck.
