Transfer settings and addons from old firefox version

How i can transfer settings and addons from an old firefox version in snap?

i have version 2971 and 2987 installed, i start firefox 2987 with an symlink in my ~/bin directory. but at firefox 2987 are seperate settings as in 2971. How can i transfer the settings into the new version?

Ok, I’ve already solved it myself. I changed the profile in the new firefox to that of the old firefox version and everything is there again :smiley:
