I love this add-on, it does what I want, except I'd like to change the default search engine path in order to remove commercials, change locale etc. but it seems not possible - or at least difficult since I can't figure out which files I need to edit.

This add-on keeps changing my home page, which is not something I asked for. Uninstalling...

I don't know why it's so difficult to just add a search engine in firefox these days, you used to be able to right click any search box and select "add search engine". This does exactly what I want, I don't need all the other stuff from the official addon.

As mentioned in the other reivew It does change your home page but it's a couple of clicks to change it back,

It changed my search engine, which is what I wanted. But it also changed my start page, and I didn't want that. There was no option to make it not change my start page.

So I uninstalled it.
