I am using Thunderbird for a long time. But since it started using add-ons in a way, it has become soooo slow most of the time. I don't know which or what. And I don't have the time nor urge to go look after it, which or what add-on is causing the problem. Yes, one can restart with all add-ons off. But it is bot easy to find to do that. I would simply be able to start Thunderbird without any add-ons. And give me the choice to easily turn add-ons on or off. If this continues to be so slow, I go look for an alternative.
