There are incompatibility problems between Ask and Firefox which can affect performance in a variety of ways. See http://kb.mozillazine.org/Problematic_extensions

Remove the one you appear to have installed now by clicking the Firefox button, go to Add-ons, then Extensions.

First, make sure that you don't already have that Search Engine installed.
If you do, does it work? (It may be installed, but corrupted.)
If it doesn't work, try to un-install it from Manage Search Engines at the bottom of the drop-down.

If that doesn't work, remove that search engine from the \searchplugins\ folder in your Profile folder.

Then try to install it again.

Ask.com is a search engine which looks for results within its advertiser database. If it doesn't find any, then and only then will you get neutral results. Is this what you really want?

I dont use Ask Jeeves as a search provider but only their dictionary and thesaurus. In SouthAfrica the english used here 9-(spelling etc) is based on the Uk

You could maybe install this add-on: https://addons.mozilla.org/en-us/firefox/addon/british-english-dictionary/ instead.
