Problem with TrafficLight recently

Hello.

I'm using TrafficLight on a PC.

In the past few weeks, TrafficLight has stopped displaying the green/yellow/red icons next to search results in Google, both in Firefox and Chrome.

On Bing, the icons appear on some but not all search results.

I've tried removing and reinstalling the extension, including restarting the PC, and sometimes it works, sometimes it doesn't. Right now, it isn't.

I'm using FF 81.0.1 (64-bit) and Chrome 85.0.4183.121 (64-bit) on Win10 Home 10.0.18363 Build 18363.

Thanks!
