Firefox 133 broke the look of my Firefox, and updating this mod caused additional issues.

[Nicholas-Steel]

1. Does the issue occur without any files inside /chrome/ folder? No.
   -> If it does, it might be a Firefox bug not related to this projects files, so "the issue report" is most likely wrong here.

2. Issue description, userChrome.css/userContent.css 'settings' the issue occurs with and steps to reproduce the issue:
   chrome.zip Here is the contents of my Chrome folder, the issue is I think clearly conveyed in the images further down in this report.

3. Does the issue occur with the most recent version of CustomCSSforFx (release/test/dev build)?
   -> Check here: https://github.com/Aris-t2/CustomCSSforFx/releases <-

4. Screenshots showing the issue (drag & drop images into this post):
   So far I've noticed (after updating these tweaks) the Inactive tabs are the wrong colour, Active tab is the wrong colour, Close Tab button on the Active Tab is invisible, gray background in Address Bar and Search Bar.
   
   The popup for Autocompleting a URL in the Address Bar is also broken, it's positioned higher and takes up entire width of display as seen in the below image (the narrow white line at the very top middle of the image is a bug with the Windows Snipping tool in Windows 10 and should be ignored).
   

5. System information

• OS & OS version: Windows 10 22H2
• DPI/HiDPI/scaling value, if not 100% (e.g. 125%, 150%...): "Make Text Bigger" in PC Setings -> Ease of Access is set to 120%
• Firefox version: 133
• Firefox theme (e.g. default, build in light/dark, external theme + link): System Theme/Auto

If this is wrong use of Issue Reporting than let me know where I should go to discuss this kinda situation.

You have to get and use the latest release of this projects files.
Rebuild your userChrome based on the latest userChrome.css

Some things I enabled during tests with your setup:
menubar_color.css
tabs_below_navigation_toolbar_fx133.css
megabar_expanding_breakout_disabled_fx133.css
urlbar_background_color.css

Not sure why your tab text looks like that. Start with a clean setup and enabled everything step by step.

hmm, I thought \config\ folder and the userChrome.css and userContent.css files don't usually need updating (since there's no easy way to do that that keeps your changes), just updating the css and maybe the images folders are usually all that needs to be done.

Looking at my copy of userChrome.css and the latest copy I... guess things have changed quite a bit since v4.1.3 (at least formatting wise) and new entries may have been added/files renamed.
