If you encounter an issue while using Fission, it can be useful to create a new profile in about:profiles with the default settings (Fission will be OFF) and attempt to recreate the issue. This can be useful to determine if issues are Fission-specific. If you encounter an issue that only happens with Fission, please be sure to file a bug in Bugzilla about it as described above!
 
If you encounter an issue while using Fission, it is possible to open a non-fission window within the same browsing session using the "New Non-Fission Window" item in the hamburger menu. This can be useful to determine if issues are Fission-specific, or to work around fission-specific breakage. If you encounter an issue that is fixed in this way, please be sure to file a bug in Bugzilla about it as described above!


To disable Fission, reset the "fission.autostart" pref back to "false" and restart Nightly.
