Firefox Add-ons

[clintin at linuxmail.org]

I have had a problem with getting add-ons with Firefox 3.6.3 (current) 
with the  add-on installation or update failing with a Download Error 
-228 (download failed).   This is occuring on two computers where I 
have installed the 10.04 Release candidate.  Process is as follows 1)  
Find an add-on  2) Click on Install and wait for about 30 seconds or 
so. 3) Click Install Now and wait again.  Installation times out and 
fails with a -228 download error.

What is interesting is that I can go to a Windows machine, put the URL 
in the browser and get an immediate download of the .xpi file which I 
have been doing but then I have to copy the file over to the Ubuntu 
system so that I can install it using open file.

Anybody else seeing this problem or know what is going on?  I do see a 
lot of reports of the -228 download error in a Google search but none 
really current.

Thanks.
