Hello! After installing update 129.0.1, in the profile folder, along the path: AppData/roaming/mozilla/firefox/profiles, a folder "extensions store menus" appeared, it contains the file data.life.bin, which changes its modification date as if it was synchronized when the browser closes. I would like to know if anyone else has this folder and file? . I checked the file for viruses, it is clean. Thanks in advance for your answers).
