Hi, I want to solve this behavior when scrolling in 'about:addons' page. I put a background-image in body using 'userChrome.css' and in 'userContent.css' I set transparency in some elements backgrounds, but when I scroll the #main element goes behind .sticky-container element, so here is my question: Can I make the #main and .sticky-container elements don't cross, I tried to set a margin, clip-path, etc but I couldn't make any progress to solve it.

hi, seem like Firefox removed [tabsintitlebar], I wonder if deleting it is the right way to solve it or that condition was replaced with another and its needed to put that one? I'm using hide_tabs_toolbar_v2.css

hi, with the recent Firefox changes I wonder if this style navbar_tabs_oneliner_menu_buttons_on_right.css could be more simple or still will be necessary the other style of window controls window_control_placeholder_support.css

Tested in Firefox developer edition Hi, I used this two files (window_control_placeholder_support.css + hide_tabs_toolbar.css) for tree-tabs but seems like they will need an update. The window controls only shows when press Alt and the menubar shows behind the urlbar.

Issue in Firefox beta hi, I set a z-index in 2 elements but don't work and I can't solve it. I have this code to move the hamburger menu to left top side:

:root:not([chromehidden~="toolbar"]) #PanelUI-button {
        position: fixed;
        display: flex;
        top: var(--windowed-top-padding, 0px);
        left: 0px !important;
        z-index: 3 !important;
    }

and I have this code to move higher the Firefox Sidebar:

:root:not([sizemode="fullscreen"]):has(sidebar-main:not([expanded])) {
        & #sidebar-main {           
                /* Bakground-color necessary for gradient line color */
            background-color: var(--lwt-frame) !important;
                /* Top-bottom margins */
            padding-top: var(--padding-top-left-sidebar) !important;
                /* Gradient line */
            margin-top: calc( -1px - var(--bookmarksbar-height-personal, 0px) - var(--toolbar-height-personal) - 
                             var(--Space-before-gradient-line)) !important;
            border-inline-end: 1px solid red !important;
            z-index: 2 !important;
        }
    }

the problem is the hamburger menu stay behind the Sidebar, I wonder why the z-index don't work.

hi, I would like to know how to Apply margin to web content but not when a video is in fullscreen? and keep the margin when Firefox is in fullscreen. I mean I would like to apply a margin to web content that not affect when a video is in fullscreen. I used this code:

:root:not([chromehidden~="toolbar"]) {
        
        /* Web content */
        & #appcontent{
            margin-inline-start: var(--my-vertical-toolbar-width) !important;
        }

        /* Sidebar + sidebar content */
        & #sidebar-box[checked="true"] {
            margin-inline-start: var(--my-vertical-toolbar-width) !important;
        }

        /* Sidebar + sidebar content + web content */
        & #sidebar-box[checked="true"] ~ #appcontent {
            margin-inline-start: 0px !important;
        }
    }

but that applies a margin when a video is in fullscreen, I tried too this code but removes the margin when Firefox is in fullscreen:

:root:not([chromehidden~="toolbar"],[sizemode="fullscreen"]) {
     ...
}

hi, I'm using window_control_force_linux_system_style.css and works fine to get the theme styles of the system, but the ':hover' is working bad, the ':hover' effect keep the image or background color even if I'm out of that buttons. with other system themes the effect is more noticeable.

Hi, I used this code and it used to work perfectly, but I tried it just now and I'm having some visual issues like in the screenshot. 1.- the url border (not open, not focus) display 1px inside the url default border. 2.- when urlbar is open the border don't expand properly. PD: I'm using Firefox beta.

hi, I wonder if is possible to fix this rare behavior when I apply the next css in the new-tab:

body{ 
backdrop-filter: brightness(99%);
}

if I don't add the filter there isn't a scroll.

hi, I'm asking for help to solve this inconvenient when I try to replace the default wallpapers in newtab page. Fist of all I'm using the developer Firefox version that use beta version to do this.

I have activated this preference in about:config page:

browser.newtabpage.activity-stream.newtabWallpapers.enabled to true

after that I replaced the wallpapers thumbnails successfully with the next code:

/* Miniaturas de wallpapers */
    
/* Dark */
    
.wallpaper-input.dark-landscape { background-image: url("../newtab/wallpaper-dark.png") !important; }
    
.wallpaper-input.dark-panda { background-image: url("../newtab/wallpaper-dark2.png") !important; }
    
.wallpaper-input.dark-color { background-image: url("../newtab/wallpaper-dark3.png") !important; }
    
.wallpaper-input.dark-sky { background-image: url("../newtab/wallpaper-dark4.png") !important; }
    
.wallpaper-input.dark-mountain { background-image: url("../newtab/wallpaper-dark5.png") !important; }
    
.wallpaper-input.dark-beach { background-image: url("../newtab/wallpaper-dark6.png") !important; }

but when I try to replace the wallpaper for the first image in newtab page it don't work with the path I used to use, for example this code:

body:has(#dark-landscape[aria-checked="true"]){
--newtab-wallpaper-dark: url("../newtab/wallpaper-dark.png") !important;
    }

and only works when I use a url for the new image like this:

body:has(#dark-landscape[aria-checked="true"]){
--newtab-wallpaper-dark: url(https://i.imgur.com/It1Ugaa.png) !important;
}

so I wonder if is my mistake or is a Firefox bug, or maybe there is a trick to solve it? cause I would like to use local images and not urls.

I'm using this stile from @MrOtherGuy : vertical_popup_menubar.css and that makes the menu items from Library disappear, I would like to that style not affect the Library window.

I'm using Firefox-beta v.125 on Manjaro-KDE, I use the code from here: window_control_force_linux_system_style.css but seems like don't work right anymore, the system buttons appear overlapping the default, maybe that could be a temporal issue cause is beta version, I don't know.
