Firefox 53
GOG.com version 2 (with colour)
Remove the dark menu overlay

Edit: Wait!. I just found out myself. This error was totally on me - sorry! You do remember this CSS script to remove the purple bar? I still had it activated. Turned it off and transpoarency went away. Now it's nice grey. Sorry again for the confusion.

Looks greeat now!

Thank you so much - this all now seems to be working. And I can now get rid of that awful morbid black nav bar. Thank you :)

EDIT - also another thanks as the fonts now seem to be at a readable size too!

Is there a way to prevent the page from showing it's ugly original face whenever the page is loaded?

Version 2.18.1 is out. I touched up the themes for imitating previous GOG designs, with the help of archive.org. You can now make the navigation bar look similar to the second or third design from the GOG website.
This is something I'm investigating. I have a way that will probably work, but it involves re-arranging a lot of the code. I might get a chance to work on it this weekend.
That explains it! :)

thank you for your awesome work.

This is great - thank you.

Just trying this out for the first time using 2.18.1 with Chrome. One question I have is what is the option "Remove the dark menu overlay" supposed to do? When I have this checked I see no effect on the menu or darkening of the web page when I hover over a menu item.

Is there a way to have the top menu slide up and out of the way and reappear when at the top of the page or when the mouse is at the top of the screen?

Yes, third theme is nearly identical to the one I used before. However it seems to me that the size is a bit small (and of course there are still those arrows visible - don't know if this could be changed). I thank you so much that you designed this amazing themes so fast (I was thinking about not using GOG for the next few days when GOG surprised me with this new depressing black look - not anymore :)).
I just turned this on to test (on firefox) and yes, it is supposed to turn off the dimming effect when hovering over the menu bar.

In that case, I can advise that this is NOT working in Chrome - the background darkens even with the option checked.

Make sure BE is loaded before testing. If you've set the option to remove the purple bar, then watch for that bar to disappear.

Several times I've brought up the site and it took several seconds for the BE corrections to kick in.

Yet another quick update. Version 2.18.2 is up and should be arriving on all browsers shortly.

I changed the names of all the themes, which unfortunately will effectively reset your theme selection, but you can go back to the settings and change the theme back to the one you like.

The "GOG Classic 2014" theme (the one which imitates the appearance of GOG's navigation bar from late 2014 until it went dark yesterday) has had a lot of fine-tuning.

Finally, if you were having trouble disabling the menu overlay then this update should fix it.

Yes, it is supposed to. Here's what it looks like for me.

Thanks for the update. This has fixed the menu overlay issue for me in Chrome :)

Weird, I switched between themes, and now it shows for me too. Cheers.

After updating to Barefoot 2.18.2 and reloading the GOG page, the Barefoot item no longer shows up on the GOG navigation bar. I was using the default new navbar at the time. Upon restarting my web browser to see if that did anything helpful, I got the same results also. I brought up the Firefox Addons page to try tinkering and the page came up but sat there infinitely trying to load and the browser would no longer respond to input, giving the spinning mouse icon. After a minute I terminated Firefox.

I restarted Firefox which restores open tabs by default and when the addons tab loaded the browser hung again instantly not responding to input. I tried restarting it several more times and the browser hangs every time. I decided to start Firefox in safe mode by holding down SHIFT when clicking on the Firefox icon, and the browser came up no problem. I went into the Addons screen and disabled Greasemonkey then exited and restarted normally. Firefox loaded with all of my tabs including the addons tab and now responded normally. I re-enabled Greasemonkey and the browser hung again.

Barefoot Essentials 2.18.2 is the only thing that changed in the minutes when it worked until the hang started happening so I speculate that there might be something causing a problem in the new script. I'm unable to just disable Barefoot however because when Greasemonkey is enabled at all now the browser hangs, and it looks like the only way to disable Greasemonkey scripts is if it is enabled. So I'm running with Greasemonkey disabled for now. I'll probably have to hand edit some Firefox configs to manually disable Barefoot later on.

Anyone else having this problem? Firefox 53/64bit on Windows 7/64bit here. 2.18.1 was working fine for me BTW.
