Being able to install add-ons using a browser is a valuable workaround. 
For a long time the search for add-ons within Thunderbird would miss 
many add-ons. That's working right now, but could easily break again. It 
can also be much easier to search for an add-on using a browser due to 
back buttons etc.

Being able to install add-ons that were downloaded via a browser lets 
somebody get updates for broken add-ons that are only available on 
github etc. There are also some popular add-ons that were never 
submitted to For example, many of the add-ons at . I assume some companies 
have developed some add-ons just for their own employees use.
