Click the puzzle-piece icon, pin Zeqlabs Flash, then open any YouTube video. The Flash panel appears right on the page.
Troubleshooting
“Manifest file is missing or unreadable”
You picked the wrong folder. Select the folder that contains manifest.json at its top level — not the folder above it.
The extension disappeared after a restart
Don't delete or move the unzipped folder after loading it. Put it somewhere permanent first, then load it.
How do I update it?
Download the new .zip, unzip over the old folder, then click the refresh icon on the Zeqlabs Flash card in chrome://extensions.
