I use the regular Opera Browser 114.0.5282.102. I can choose on the Theme options between "Browser Preferance", Light" Dark". When I open the inspector, its light mode, when I go to the options, it is shown as being set to "Dark". Switching to anything resets it. Opening and closing the inspector tab makes it white, no matter which option is chosen. Disabled all extensions to test if it was one of them, no difference. Extensions:
"Server IP", uBlock Origin, Zoho Vault, Session Buddy, Laravel TestTools (Disabled 98% of website visits) ImTranslator, Dislikes in YT.

When I ask about coding help, there's always some weird <link></link> tags and when I mention this to Aria, she can sometimes correct herself, but I have to do this for every new chat and it doesn't always work, which is annoying. I dont get what triggers it, I just ask normal coding questions:

Im trynna remove the close button on tabs, because when there are 100 tabs its hard to click it. I use MMB to close it anyways. I've got this so far

{
	"manifest_version": 3,

	"name": "Remove X on tabs",
	"description": "Remove the X on tab",
	"version": "1.0",
	"content_scripts": [{
        "matches": ["<all_urls>"],
        "css": ["default.css"]
    }]
}

default.css

.tab-close { display: none !important; }

I have no idea whats the class name or how I can do this, but I think this code is pretty self explanatory of what I want to do. If anyone has any clue of how I can achieve this, help me out.
