Node highlight gets stuck, doesn't go away

There is an issue with the latest version of Firefox Developer Edition, the node highlighting gets stuck.

All I’m doing is inspecting and hovering over a node, where it highlights the element, and that highlight just never goes away.

Hi @jonny ! Thanks for the report. We are already tracking this issue at

Do you reproduce this issue very consistently? When testing here, we rarely manage to get the issue, but for some users (maybe you included) it seems like it’s very frequent. Any additional info that could help us reproduce this?

I would say it’s infrequent, as I’ve tried to reproduce it and couldn’t. It has happened about 5 times, since I upgraded around a week ago.

I’m sorry I can’t be of more help, if I find any hint of a behavior towards reproducing the issue, I’ll post back right away.
