Using Firefox-developer-edition hi, I need help with this new Firefox Feature, seems like the sound tabs get larger when the user is moving any tab. I tried to reach the code, but I can't, I want the 'sound-Tab' to keep the width.

Update: Seems like this code is causing it, maybe there is another way to set a max width?

@media not -moz-pref("sidebar.verticalTabs") {

    #tabbrowser-arrowscrollbox[orient="horizontal"] {

        /* Horizontal tab size for ungrouped tabs */

        &>.tabbrowser-tab[fadein]:not([style^="max-width"]) {
            max-width: 168px !important;
        }

        /* Horizontal tab size for grouped tabs */

        &>tab-group:not([collapsed]) .tabbrowser-tab[fadein]:not([style^="max-width"]) {
            max-width: 168px !important;
        }
   }
}

decrease the maximum width

Exactly, the default is so large, like a sausage.

Then you could just do it like this:

@media not -moz-pref("sidebar.verticalTabs") {
.tabbrowser-tab{max-width: 168px !important}}

Seems like other code combined with this are incompatible (with a tab with sound) in my particular case, first I have to figure it out what of my other code is in conflict, rare all this situation. With your latest code, the issue persist.
