[conspire] even though I install an add-on to create a tiny url in Firefox, the add-on is not available

[Darlene Wallach]

I installed an add-ons to create a tiny url, TinyUrl Creator 1.0.5 and
TinyUrl Generator 1.0.12 to Firefox - Mozilla/5.0 (X11; U; Linux i686;
en-US; rv:1.9.2b5) Gecko/20091218 Remi/fc10 Firefox/3.6b5, neither
add-on shows up in the tools drop-down menu of firefox nor when I
click the right mouse button on a link or webpage.

I also can't find an add-on to shorten urls for SeaMonkey Mozilla/5.0
(X11; U; Linux i686; en-US; rv:1.8.1.23) Gecko/20090908
Fedora/1.1.18-1.fc10 SeaMonkey/1.1.18.

Any suggestions as to how I can generate short urls?

Thank you!
