Auto resize Firefox searchbar

I am constantly switching between the Firefox address bar and searchbox to locate content. If like me, you find the minuscule searchbox inconvenient for long search strings, the following extension might be of interest.

The Searchbar Autosizer automatically increases the size of your searchbar to reflect the length of your search term(s).

A worthy alternative to manually editing your userChrome (which may still be limiting depending on your searches). If you prefer something a little less flexible, add the following to your userChrome.css file [located in your Firefox profile]:

/* Make the Firefox Search box flex wider */

#search-container, #searchbar {
width: 250px !important;
}

Doing so will transform your searchbox to a 250px fixed with box.
