I'm not sure when it started (this week maybe?), but I've been noticing a small graphic appear to the right beside the Firefox icon when I hover over it. The same graphic also appears when hovering over Thunderbird's icon. Does not appear when hovering over any other icon on my task bar. It appears whether I am connected to the internet or not. I ran Malwarebytes latest build antivirus, which found nothing. Any ideas what this graphic is and/or what is it for?
I've made a screenshot, which I'll attach.
Running Firefox 133.0.3 64-bit, on Windows 11 Home (Build 22631.4602) , using DuckDuckGo as the search engine. The version of Thunderbird I'm running is: 128.5.2esr 12th Gen Intel(R) Core(TM) i9-12900K 3.20 GHz
