User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:54.0) Gecko/20100101 Firefox/54.0 Build ID: 20170616104331 Steps to reproduce: I'm not able to reproduce this with perfect reliability. It sometimes happens when loading Facebook or other big, complicated web pages. Actual results: The "A web page is slowing down your browser" dialog appears at the constant area, then immediately disappears. A short time later it will appear and disappear again. This typically continues until I close the tab. The dialog is never on screen long enough to click either of the buttons. Expected results: When this dialog shows up, it should stay around long enough to click one of the buttons.
Sorry, that should say "the dialog appears in the content area".
Component: Untriaged → Notifications and Alerts
Product: Firefox → Toolkit
Change of chrome height and repaint on each notification toggle dosn't help with performance either...
This bug is about a consumer of a notification API, so doesn't belong in the Notifications and Alerts component. This is reporting issues with slow script detection but I think the behaviour is intentional.
Product: Toolkit → Core
Summary: The "A web page is slowing down your browser" dialog flickers on and off → The "A web page is slowing down your browser" (slow script) notification flickers on and off
Will revisit priority when we have solid STR. Does this behavior impact usability or is a temporary flash and then gone?
Priority: -- → P3
The notification appears and disappears repeatedly, usually until I close the tab.
Can you still reproduce the issue in latest stable, Beta or Nightly?
I can no longer reproduce the problem in 57.0.4.
