ohnoreflow

Oh no! Reflow! is a WebExtension to help front-end Firefox engineers detect uninterruptible reflows in the browser UI.

Installation

You may need to set xpinstall.signatures.required to false and extensions.experiments.enabled to true in about:config in order to install.
Click here to download Oh no! Reflow!
Go to about:addons, and click "Install Add-on From File", and then via the file picker, find the ohnoreflow.xpi you downloaded.

Add ability to coalesce similar stacks
Hide rows if the number of reflowed frames was actually 0 (depends on Reflow API modification)
Add ability to update signatures without requiring an add-on update
