"shortcuts" plugin no longer works, none appear

Question

Google Shortcuts 2.1.6 is installed. Windows XP, sp3. It was working as described. Dont remember what change killed it. Icon no longer appears. Set up for drop down list. Tried uninstalling/reinstalling several times with no success.
Works great in my laptop/Win 7.
Some of the services are set up as bookmarks (since shortcuts quit). They work fine that way.

Answer 1

n Firefox make sure you have at least two (2) tabs open - (Ctrl+T opens a new tab)
In the address bar of one tab, type "about:config" - minus the quotes, of course
You'll see a warning. Click "I'll be careful, I promise" and continue to the configuration page.
There's a search bar at the top. Type "js" - again, minus the quotes.
In the results you'll see pdfjsviewer.disabled with a vaule of false. Click it once, then right click it and choose Toggle to make the value "True".
Close that tab.
Click Tools>Options and go to the Applications tab
Locate Adobe Acrobat Document (or Portable Document File (PDF)) in the list and click the drop-down to select "Use Adobe Reader (in Firefox)". (Mine doesn't have that because I also have Acrobat Pro installed)
Click OK.
Click Tools>Addons to see that the Acrobat plugin is installed
Close and restart Firefox. PDFs should now open in a browser window with the Reader plugin.
Note: This doesn't work for me since the update to 23 and I should have the choice of Reader or Acrobat plugins. Firefox is trying desperatelt to FORCE users to use their crappy PDFJSViewer, which doesn't handle multimedis or forms PDFs.
As to the NPAPI and security risks, that's blown WAY out of proprotion. There are antivirus companies trying to sell their products to Mac users (who will NEVER need them) and they use this "urban legend" to bolster their case.
