I am trying to install the "Send Later" add-on to the Thunderbird 3.0 by Tools > Add Ons > Get Add-ons. Click install, select "sl8tr.xpi". Then I get this message. ""Send Later" will not be installed because it does not provide secure updates."

I tried the about:config, then added the extensions.checkUpdateSecurity = false and it still doesn't install. I get the same error as above. I don't know what else to do.
Can anyone help me? Thank you.

but there is no Send Later'' add on, unfortunately...
Can be you be more specific posting the link of the add-on you call ''send later''.

A long, long time ago I remember there was an add-on ''send later'' but it did not work well and it was before Thunderbird 2.0.
This add on had never been updated for upper TH version.
Best regards
Thank you,

Please don't create duplicate threads in other forums asking for help for the same problem. This thread is a duplicate of viewtopic.php?f=39&t=1686855 . Please continue this discussion in the other thread. I'm locking this one.
