I noticed recently (I think it was around .125) when I'm doing work in a 2nd tab my logs tab goes blank.
I frequently work with multiple tabs open to edit code, test the device and watch the logs. But I can do something like save the code and the logs page will go blank as per the photo. If I hit refresh on it, it returns to normal.
Here is another example I've seen. When I save a driver this shows up in the log. Its got no driver associated or null in the selected driver. That couldn't should even be outputting to the logs but something is causing it to.
I'm using the latest version of firefox and not sure where the issue could be that is causing this.
Just some strange behaviour I figure I would report.
