Do you know why Firefox is dying?
Do you know why Firefox is dying? Firefox start process of dying from when you update Firefox to Quantum and make 90% of old addons incompatible. For example, in most recent versions of Firefox I cannot customize right-click context menu. All the old addons to customize right-click context menu now become incompatible. The most advantage point of Firefox is customized addons is gone when Firefox update to Quantum version. Fix this problem fast or Firefox will die. We all miss the old versions of Firefox with many fully customized addons.

Mozilla need to provide tools to convert all the old addons to newer versions compatible with Firefox Quantum automatically. Without long list of customized addons Firefox cannot compete to commercial closed-source Chrome.
Addon are up to the developer to update their Addon so you need to contact the Addon developer to update their Addons if that is the issue. Your best to make a list of your Addon to reinstall them on a update or new install of Firefox if that is the case.
