Mozilla browser feature request

A new preference I'd like to see added to the Mozilla Organization's browsers is control over the automatic selection of text in the location bar or search box when switching between applications.

When the cursor is left in either of these input areas and then I switch to a different application to confirm whatever I was typing (a long URL most often), then when I switch back the cursor focus returns to where I was typing but the text is automatically selected and I have to either click somewhere or press the correct key to continue typing - otherwise the existing text is removed.
