I’m not sure which one but it’s whatever the basic one. As far as I know I haven’t changed it from whatever the one is the default.
It’s certainly possible that this is a browser problem on my end. I only started noticing this when I did a completely new reinstall of the system I’m using and installed the newest version of Firefox. Before I did this, I didn’t see anything like this except that I couldn’t do a personal status update post like many of you do. I still can’t.
Also, not to put more into the issue, but there’s this.
