Rated 5 out of 5 stars

Very functional extension.

A simple ability to select which accounts' emails should be checked - very useful for those with multiple email IDs.

A pity that Mozilla, for all its good work, does not provide the extra support such developers need to keep them in step with Mozilla's development plans.

Here is hoping that Mozilla and such developers work well together and such useful extensions have an easy path to staying usable on new versions of Thunderbird.

Thanks to the developer for an excellent extension.
