Extension Wizard is very helpful
After a couple of days I finally could make an extension work. This was only possible with the help of the Firefox/Thunderbird Extension Wizard
. fill the form, download the zip, it works
I filled in the required fields, and some others as well; checked a few checkboxes, i.e. "Use Unix line endings"; and finally clicked "Create Extensions". I extracted the downloaded zip file to my Development directory on my desktop and updated the development profile for firefox according to the included readme.txt. When I started firefox with the development profile, the extension was installed and I actually saw results! coming next
This is a huge step forward for me
I'll next play around with the current code to get a feel what does what. And eventually there will be a shiny "hello donationcoder" extension for FF3.
Hopefully the wizard will
help others too.
