Tab title disappears indefinitely if I move tab to new window while something is loading in iframe
I have a problem with Firefox Beta 53. It also happens in Firefox ESR 45. Sometimes when I move tab to new window, the tab title disappears indefinitely. It happens unpredictably, however, I noticed one specific scenario when it happens 1. Open this url in a new tab: data:text/html,<title>hello world</title><iframe src="data:text/html,<body onload='document.open()'>"></iframe> 2. Move the tab to new window Result: The tab title isn't visible Expected: The tab should display the title
Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:55.0) Gecko/20100101 Firefox/55.0 I have tested your issue on latest FF release (52.0), latest Nightly build (20170316030211) and managed to reproduce it. I can see that tab title is missing when tab is moved to a new window.
