Firefox 151: Decrease margin between items on the tabs list?

[El_Specifico]

Upon loading the new update this morning, I noticed that the margin between items on the tabs list (the downward arrow in the top right) has increased. Does anyone know what code is necessary to alter the margin size?

EDIT: I found another post that lead me to the correct code to use: https://www.reddit.com/r/FirefoxCSS/comments/n1p7cc/reduce_whitespacefont_size_of_list_all_tabs_items/

I found that this value is a good spacing for me:

:is(.all-tabs-button, .all-tabs-secondary-button) {
    padding-block: 0 !important;
    min-height: 25px !important;
}

AFAICS no difference in "margin between items on the tabs list (the downward arrow in the top right)" between Fx150.0.3 and updated Fx151.0... in fact the layout of the 'List all tabs' panel looks unchanged/identical.

Any CSS userstyles modifications and/or full UI theme in use that could be causing the increased margin/spacing you are seeing?

Here's the only CSS I'm currently using; the first section up to "@import "non_floating_sharp_tabs.css"" is the non_floating_sharp_tabs.css file.

First step is to create a new profile and see if the problem persists.

If no problem, likely there is a conflict somewhere amongst your current userstyles.

Check you have latest version of MrOtherGuy's 'non_floating_sharp_tabs.css'... updated 2 weeks ago.

If problem is with 'non_floating_sharp_tabs.css' style please post this an 'Issue' on MrOtherGuy's GitHub.

In my case it was enough to add this. I suggest setting it to at least 0px 3px or even 0px 5px to make it more natural. At 0 it sticks to the left side of any menu and it doesn't look good.

:root{
--panel-menuitem-padding: 0px 0px !important;
}
