This is a fork of the original extension from Mossop that just fixes the icon problem.
It gets the icon URLs from google automatically, but also allows the user to set a custom URL.
The XPI that can be installed into Thunderbird is in the releases tab.
The original project is not mantained anymore. Part of the original README follows below.
This is an extension for Thunderbird which allows you to view webapps in Thunderbird's tabs.
There are many extensions for viewing webpages in Thunderbird. This isn't what I think Thunderbird is for, webpages can be viewed in Firefox or whatever browser you prefer. Thunderbird is my communications centre and I use it to display communications related webapps like Google+, Google Reader, Google Groups, etc. and I want to be able to use those easily, opening links in the default browser where relevant.
The main goals are:
- Allow the user to configure a set of available webapps
- Provide a way for the user to open each webapp in a tab
- Any attempt to open a configured webapp (e.g. from a link in an email or anywhere else) should open it in the existing tab for the webapp if one exists or a new tab for the webapp in Thunderbird
- Any links clicked in the webapp that are to other sites should open in the default browser
- The webapp should behave as well in Thunderbird as it would if opened in Firefox
