Rated 4 out of 5 stars

Lightning was a great add-on till last week. I use it in connection with google calendars of which I have six calendars in two different accounts. Last week, the Google Calendar Provider nerved by opening six windows at once at every launching asking to confirm privacy things. Those pop-ups, coming together with several alarms at once, could not be answered because Thunderbird crashed each time. After the fifth try I started Th. in safe mode, deactivated the Calendar Provider, then it was possible to delete the calendars, restart Th. in normal mode and reinstall all the calendars again. So far so good. But there is one calendar (actually my most important) making trouble all the time. Hardheadedly, it wants write-protection. I can clear the check-box as often as I want - at the next start it reappears either with the padlock icon again or with the exclamation mark in the triangle having a secret meaning I am not to know. I could google till doomsday, I don't find any support answer fitting to my problem. I would like to know: What happens here and who is at fault? And, most important: How can I beat that lousy unfitful calendar?

Working very capriciously. First, I could not import my very spacious FF PW manager content (there was no csv or html file, only one signons.squlite which I suspected to content all my PW data).
Sometimes, even if a login has already worked with keefox and the web address is exactly the same, it wants to save again; at other times it doesn't store at all. Does not work with websites where we have more than one login in the family (i.E. Amazon or Ebay). In those cases, it pretends to know only one of the logins, and you can't even tell the preferred one.
The worst was that after deactivating, then uninstalling keepass, the genuine password FF manger would not work again. We had to set back FF and consequently reinstall all the add-ons. Never again.

Improvable Rated 3 out of 5 stars

Sometimes it works, sometimes not -- even on the same website, it would work one time and the next time it wouldn't. Registered logins are often not changed automatically when I change the password.


New Version has a big bug Rated 5 out of 5 stars

This calendar is very useful because you can connect it with different google calendars and share appropriate dates with different people. But if you use a calendar, you become a bit dependent on it, don't you? So I would not recommend to jump positively on every very first Thunderbird update prompt because it happened to me twice that Lightning was not yet fit for the change, and I had no calendar for some hours in times with high rates of new appointments with clients at the phone. This time, I waited some days, but I had to find out that there is a bug with entering new net calendar dates, which has not been fixed yet. So, if you don't wait with updates, you become upset. Five stars though because if it works, it is a really fine tool.

Great and indispensable tool even for dummies who can just write html code and don't always understand why something on their pages doesn't work.

Never any price comparison Rated 1 out of 5 stars

I have this add on for more than one year, I suppose, but forgot completely about it because it never ever shows any comparison price. Maybe I visit the wrong places ;)
