Updated Firefox, Lightning now disabled. Need Lightening back as important events are trusted to it. Thunderbird now at 38.0.1

Chosen solution

Extensions Lightning, 4.0.0.1, true, {e2fda1a4-762b-4020-b5ad-a41df1933103}

Lightning is enabled and should be working just fine. Do you still get any error messages? Can you explain the problem in more detail? What are you doing? What happens? What do you expect to happen?

If you attempt to install Lightning in Firefox this will ultimately fail.

Lightning should get updated automatically along with Thunderbird.

Press the Menu button ≡ - Add-ons What is the current status of Lightning in your Add-On Manager? Do you have version 4.0.0.1?

Yes, I confirm it is 4.0.0.1

I am not attempting to install Lightning in Firefox. This is the message I receive having updated Thunderbird. I was offered an upgrade of Lightning, I accepted, then got this message. It was showing as disabled owing to incompatability, now having re launched Thunderbird, Lightning it is listed in the addons but is not available.

Lightning is enabled and should be working just fine. Do you still get any error messages? Can you explain the problem in more detail? What are you doing? What happens? What do you expect to happen?

Does this now help? I could still do with knowing how to retrieve my valuable calendar so I can load on another pc that will accept it. Thanks for your help.

Lightning is not working. I expect to see the "events and tasks" menu between the message and tools menu, it is not there. (if it was I could export a copy of my calendar for use on another pc running older versions) I expect to see the events and tasks icons at top right. They are missing. It is all as if Lightning is disabled. (which is indeed the message I originally got. It said this is due to due to incompatability) I do not now get an error message. I could still do with knowing how to retrieve my valuable calendar so I can load on another pc that will accept it.

Try to uninstall Lightning via the Add-on Manager. You'll need to restart Thunderbird. Is Lightning gone from the list of extensions? Report back if it's still there, and do not continue in that case.

If it's gone, download Lightning 4.0.0.1 from AMO. Follow the instructions shown when hovering over or pressing the Download button. https://addons.mozilla.org/en-US/thunderbird/addon/lightning/

Install Lightning as per the instructions, and restart Thunderbird.

Your calendar data is not impacted by this. In any case, make sure to have a backup of your Thunderbird profile folder. http://kb.mozillazine.org/Thunderbird_:_FAQs_:_Backing_Up_and_Restoring

Its back! Thanks christ1. Removing Lightning via Add on Manager and restarting, removed it from the list of installed Add ons. Re installing via Add on Manager, restored Lightning and most importantly, my calendar. Now I know what I am supposed to be doing today. Phew! Much appreciated, hope the rest of your day goes well. turkeysnipe
