Assuming you have disabled the extensions then the crash in bug 1859890 might be from before or after you disabled them. So that's kind of good -- there is no evidence of the crash happening WITHOUT the extensions. Please uninstall them and keep them uninstalled. Then let us know about any future crashes.
