I got a update notification of Firefox web browser on my system. I updated that and after installation it turned off all my addons. I have IDM installed with a epub reader and a pdf printer. I also has a addons for scanning files and saving the entire web page in pdf. None of this are working. Except a video downloader. Which allow me to download files. How can I restore the old version back again and enable all my addons.
