So since about a few days ago I noticed that occasionally whenever I right click on a thumbnail in order to try and open a picture in a new tab the menu that appears is sometimes partially or fully black. I thought it might be an issue with my browser but e621 seems to be the only site that has this happen. I use Mozilla Firefox on Windows 10. Any idea what it is or what could be causing it? Sorry for creating a new topic, I didn't know if this belongs on the bug report thread or not. Thanks a lot!

That sounds like a problem with an extension. Have you tried disabling them?

It could also be a GPU problem. Whenever my GPU driver crashes, I get some strange graphical effects until I close out my browser, but it happens so rarely that I don't remember all it impacted beyond making my tabs completely black.

Yeah, you should probably try closing the browser and starting it up again, or even rebooting, see if that helps.
