Hi Liv, We added the following line in the [https://www.firefox.com/firefox/142.0/releasenotes 142 release notes] under the Unresolved section: <blockquote>Multiselecting non-contiguous tabs to drag may result in toolbar unresponsiveness or visual glitches. Dragging any single tab should resolve this. We will be landing a fix in the next dot release with [https://bugzilla.mozilla.org/show_bug.cgi?id=1984342 Bug 1984342].</blockquote> The dot release is planned this week, so please keep an eye on our update soon!
