Review for Disable Add-on Compatibility Checks by I_am_a_Landstander
Rated 4 out of 5 stars
Lets you install addons marked as incompatible. This is great if you have a non-standard browser (like Pale Moon).
I would like to see an option to disable the incompatibility warnings in the Add-on Manager and even allow you to automatically check and install updates in the Manager. Still, it works.
To create your own collections, you must have a Mozilla Add-ons account.
