I reset my android phone Install Firefox from Google Play Store(version 66.0.2) Connect addons.mozilla.org Search ublock origin Touch 'Add to Firefox'

Pop-up message addons.mozilla.org this addon could not be installed because it appears to be corrupt


Connect ublock origin github/releases Download ublock origin rc4

Pop-up message github~ this addon could not be installed because it appears to be corrupt


Connect addons.mozilla.org again Tried other extension Same message pop-up


Reset my phone again Same result...

I have used Android Firefox with addons over 3 years, this is first time(addon install failed) (sorry for my lame English)

How to install add-ons?
