User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.9) Gecko/2009042221 Iceweasel/3.0.9 (Debian-3.0.9-1)

Currently, in order to retry the update installation after download failure, it is necessary to re-run the update check, which can take some time. It would be nice if you could simply click on a button to retry the failed update downloads, when you suspect that the download failure was transient.

Reproducible: Always

Steps to Reproduce:
1. Have a download failure when attempting to install an add-on update found by "check for updates"
2. Suspect it to be transient
3. Look for a "retry" option
Actual Results:  
Can't find a way to retry without re-running the update check

Expected Results:  
Mozilla should offer to retry the download
