I can confirm this works for me. I haven't been able to use the direct links or pasting the ID# in address bar method(s) as some had suggested, but this one works like a charm.
You have to restart Firefox twice:
- 1st for the add-on to be recognized and
- 2nd for the script [after loading the script, if you can see "Sims 3 Exchange Link Fixer" and the 2 links on the Included Pages, then a restart might not be needed.]
Steps I took:
- copy the code and save as directed
- download and install add-on; restart browser
- ensure that Greasemonkey add-on itself is enabled [Tools menu -> Greasemonkey] or next step won't work
- drag the .js file into a tab and click "Install script" when prompted, restart browser again
- go to Tools menu -> Add-ons -> Extension icon -> options button: ensure the script is listed in the "Manage user script window" and the 2 links on the Included Pages are listed
- click on the picture of the item on the EA TS3 Exchange site you wanted, until you can see the "Add to Game" and "Save File" links
- click or right-click either link to download the sim3pack file
- install as preferred via Launcher or the 3Viewer tool from jfade
- done
hth....
