handle error when extension at AMO is not found

[dapgo]

I am seeing that error at AMO () are handled ()https://addons.mozilla.org/en-US/firefox/addon/xxxx/

with followinf text and link to caa:addon/xxxx Try to find "xxxx" in the### Classic Add-ons Archive.

However different URLS available in Internet are not handled, such as

https://addons.mozilla.org/en-US/firefox/downloads/latest/1191/addon-1191-latest.xpi?src=addondetail

Can be handled errors from this type of URL?

I will check whether this can be done.
