ooooh, I wonder if I give a higher zindex to all the navigator-toolbox it could cause random problems but I will try.

Edit: Sadly changing the z-index to all navigator-toolbox cause other issues in my theme and I should change a lot of code, hate this Firefox change jeje.

Edit2: I tried this code and seems to work in some cases, I wonder what damage this could cause but the time will say:

#navigator-toolbox{
        z-index: unset !important;
    }

I’ll try it, hope works fine, ty. 💜

@[email protected] I’m gonna need your help again, sorry. I used your code to gradient border around selected tab and works fine but I see a little flash in certain situations that makes me nuts; this is the code:

.tabbrowser-tab[selected] > .tab-stack::before{
    content: "";
    display: flex;
    min-height: inherit;
    border-radius: var(--tab-border-radius);
    grid-area: 1/1;
    margin-block: var(--tab-block-margin);
  /* Edit gradient colors here */
    background: var(--general-color) !important;
    border-radius: 0px 2px 0px 0px !important;
}

When I click to select the tab, sometimes the tab is first colored with the border color and then it displays correctly, Here is a SS with the problem, there is a way to delay the colored after the tab is completely charged or some trick?

Information that heals, thanks for all. 💙

ooh, I notice a rare behavior when use this in horizontal tabs, so the issue is that min-max width cause problems, I understand.

/* Horizontal tab size */

.tabbrowser-tab[fadein]:not([style^="max-width"]) {
    max-width: 200px !important;
}

in Vertical tabs I noticed that the property of the tab that don’t close has fadein property, I tried this code to delete that empty space, but visually works but in the background the tab is still stuck.

/* Important! bug fix for tabs that keep space after close them */
    
    .tabbrowser-tab {
        &:not([pinned], [fadein]) {
            visibility: collapse !important;
        }
    }

@[email protected] hi, I wanted to bother you with another question, If you use the new feature of Vertical-tabs you maybe notice that if you have the Sidebar expanded the tabs is like they stuck in some way, I’ll show you this with new-tab pages but is the same with webpages: https://imgur.com/a/BbECuIp

I think this is not a behavior caused by a CSS or it is possible?

toggle: devtools.debugger.prompt-connection

Thanks, this open a lot of possibilities. 🖤

I updated the code and check the rest of my code and all is good now, sorry for the lost time.

I will check again…

💙I saw you updated the style, thanks.

thanks for the explanation but I can’t get it to work. you said :root but I don’t understand how, I saw a div called root inside body element, I tried too apply to html jeje I don’t know, maybe I should start to love the scroll.

ooh, thanks for the explanation, I’m sure I understand better how this works. 💙

thanks for the answer, I searched where the variable is used and added !important and that fixed, I don’t know why but all right jeje:

body{
    background-image: var(--newtab-wallpaper-dark, "") !important;
    ...

thank you so much, I will use @-moz-document for a quick solution, I will try your new code in a future cause I’m getting some issues combined with my personal code, I think jeje. Thanks for the quick answer.

thank you very much. 💙
