All data for the currently installed extensions is stored in extensions.json in the profile folder. There is no history for extension you had installed in the past that are no longer installed.

Thank You so much co-el

one of the reasons i am looking for this is because, i installed an addon that was able to copy all my saved passwords in firefox,and cant really remember the exact one after some few days i started getting login notification from most of my accounts saved in firefox

if i could trace my history i could narrow it down to that add-on i installed , i am 100% sure its an addon that hack my firefox account

if possible i will like to recommend a addon history log
