Hi there,

It's totally ok if you're not comfortable sharing the about:support information. I just wanted to provide an update here.

Recently, we added the following line in the 142 release notes under the Unresolved section:

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 Bug 1984342.

The dot release is planned this week, so please keep an eye on our update soon and hopefully you can let us know if it fix the issue.

I don't have a problem with that on 143.0.4. Can you try in troubleshooting mode?

Good evening! Yes, there are no friezes in this mode, but do I manage to use the safe mode? After all, I need extensions and other features that are not available in safe mode.

We just released 144 yesterday. Can you try to update and see if it help?
