Occasional freezes if apply page colors enabled for toolbar

[zezic]

For Firefox 89.0 this addon introduces freezes when switching between some tabs if the "apply page colors" option enabled for toolbar. Other than that it works fine.

As a workaround I disabled the "apply page colors" for toolbar, set its opacity to 0 and added the next rule to my userChrome.css to keep icons and active tab text readable:

#nav-bar,
.tabbrowser-tab[visuallyselected="true"]:-moz-lwtheme {
  color: var(--lwt-toolbar-field-color) !important;
}

With Firefox 91.0.1 I also have a lot of delay between switching tabs and disabling Vivaldi-Fox or just disabling "apply page colors" for the toolbar seems to help a lot.

Unfortunately, this is my favourite feature of Vivialdi-Fox, so I would love to see it working again. But it might also be a Firefox bug causing the delay.

happened to me too. But workaround to disable is no solution for that nice feature.
