Windows 7 Themes interfering with FireFox/Gadgets useability

I have a custom theme that I have been using for the past month.

It is a theme with dark menus that I have come to love. I have never had problems with it interfering with Firefox or desktop gadgets before.

Last night, I tried an 'Aero' theme and decided I didn't like it and switched back to my old theme. However, now whenever firefox is loaded, the page background appears the wrong color and pictures do not load. This happens for youtube, facebook, and netflix (all opened in my homepage). I have uninstalled firefox and reinstalled twice since this issue has come up and nothing has changed.

Gadgets also do not load correctly (appearance). This has never occurred before.

This problem goes away when I use an Aero theme or the Windows 7 classic theme, but returns when I use my custom theme or a high contrast theme.

I do not believe I changed any settings under my custom theme, but if we have to, we could run through all the setting under

Appearance and Personalization > Personalization > Window Color and Appearance

To see if I have accidentally filled a field that affects Firefox/gadgets

Here are some pictures for explanation:

So this is what the gadgets should be doing and this is with the Windows 7 Aero Theme




And this is how Firefox looks





And this is how the Menu looks




Everything is fine with this theme.

Okay, so this is the "Life" Theme. This is a dark theme that doesn't interfere with gadgets/firefox.




And this is how Firefox looks





And this is how the menus look




Seems to be fine, despite the obvious and drastic change of colors.

Now here's where problems come in with my theme.

Here's how gadgets look.



Here's how Firefox looks




Here's how the menus look





I never had this problem until last night and don't remember changing anything except for switching to Aeros and back.

Is there something I'm missing? Is there a way to set windows themes to not interfere with other programs?

Thanks a lot to anyone who answers, I've become really attached to this theme and would hate to lose it.

Do you mean in Firefox or in Windows?

I don't believe I initially installed any additional software to alter windows themes.

I eventually did install Universal Theme Patcher, it was an impulse decision that I made because I was trying to change the color of the taskbar in windows (which I eventually decided I didn't even want to do).

I have uninstalled it though.

There was a piece of software (add-on) that I installed in Firefox, after the issue came up, to try and fix the problem, but I ended up uninstalling it because I had no luck with it. It now doesn't show up in Firefox add-ons. However, I haven't checked the Program Files (x86) folder and there could be some left over files there.

Like I said, I have reinstalled Firefox twice since this incident, but maybe there are still files left over that are causing this to happen.

I'm somewhat comfortable/proficient with Windows, but I honestly don't know where to start backtracking and I don't even know how the problem originally came up.

Thanks for you response. :)

I did the SFC Scan and got this message:



Then when to CBS Logs and got the message: "Access is denied" and it opens a blank notepad file.

I have restarted the computer and nothing has changed cosmetically and I have still having the same problems with Firefox.

I would like to repatch the problems, but I need to be able to see them.

Should i just do a system restore?

Should I try the 3 SFC/Restart first?

( should I keep system restore as last resort ? )


Also, there were some modifications like removing start button and removing start menu user picture, will these be altered/reset by system restore?

Thanks SO MUCH for your quick response!
