Hello I have been using firefox sync for a long time to migrate between PC to PC My firefox sync profile is full of old stuff and I would like to clean up my settings by wiping out my firefox sync settings and starting fresh. However, before doing that I wish to export all my data/settings/password/cookies/bookmarks and everything, so files on my computer. Files that I can read in notepad and inspect. See which settings I have in there and decide which settings I want to put back in my new installation. I have found a locked question about this on this forum https://support.mozilla.org/en-US/questions/1065938 It mentions two plugins for this purpose FEBE (Firefox Environment Backup Extension) OPIE Unfortunately and worryingly, they have been removed from the firefox addon store https://addons.mozilla.org/en-US/firefox/addon/febe/ https://addons.mozilla.org/en-US/firefox/addon/opie/ I found a wikipedia article about FEBE https://en.wikipedia.org/wiki/Firefox_Environment_Backup_Extension a very old link to download a probably broken version https://febe.en.softonic.com/ and a reddit thread about FEBE which states that there is no equivalent and that it is not possible to export firefox settings anymore https://old.reddit.com/r/firefox/comments/t2zmjb/febe_alternatives/ as for OPIE, I am unable to find explanation of what it was, where it went or who used it I know that my profile is stored in C:\Users\user\AppData\Local\Mozilla\Firefox\Profiles\4vdt083m.default-release However the files and structure in that folder are inscrutable I would like to have control over the settings of my browser, what they are, to save them and modify them on my own terms. I would like to export about:config completely to a regular plain text file, edit them and import them back in.
