Taskbar hover reveals small graphic - Firefox 133 and Thunderbird 128

more options

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

When you hover the Taskbar button, you usually will see a thumbnail for each open window. I guess this is not what you see in the open window. Is it clickable?

Thanks for your followup inquiry, Jscher2000.

The action of hovering over the Firefox icon brings up a mini-window, which I assume is what you mean by "thumbnail". That's normal and I don't see anything odd there; I've attached an image of that. But notice how the odd graphic is still off to the right on the task bar?

I can't click it, as it disappears once I'm no longer hovering over the Firefox (or Thunderbird) icon.

Hmm, I can't think of a good reason for that to be there. I wonder if the program icon image is somehow creating a graphical glitch.

It could be icon cache corruption (the IconCache.db file). I started searching for the steps I knew for Windows 10, but it sounds like Windows 11 changed some things and I'm not confident giving steps. https://www.google.com/search?q=windows-11+iconcache.db
