Many months ago I began to use a version called 2.86 and I noted no problems. Every time I have
installed a new 2.86 Beta version over it Simple Mail fails to work properly. When I manually check refresh all
it will download one email and stop. A red warning sign appears on the email envelope icon. If I close FF 24
and reopen it the warning sign is gone and Simple Mail will download one more email and stop. If I try to refresh
nothing happens until I restart FF. FF changed the Web Developer and I can no longer find the error console although
I do no know what the reports mean usually.

Apparently no one else is seeing this problem.

Thanks
