Can you restore all the prefs and addons you changed to what they were before and try the following package? https://people.debian.org/~glandium/firefox-esr_60.2.0esr-1~deb9u2.2_i386.deb sha256: 4f092e11faf729316ea96be5b9f6ecca58ea1f001279c44406a8d505b021c17f (Others who have experienced the crash on startup are invited to try this package as well) Thanks Mike
