I'm using Firefox 8 with the Web Developer(1.1.19) add-on and Firebug 1.8.4.
Ever since Firefox 6 or 7, it has started to act weird. For instance if I type into the URL field, it properly looks for matches within the URL history but while it does this the URL field where I am typing goes blank.
It has a similar behavior for filling out forms. If I have two user accounts on a website and I start typing my email address it presents me with my two user names. However it is very difficult to select one of them as the user account field will go empty on me.
Firefox only gets into this quirky mode about half of the time. Restarting it often fixes it.
Is there a solution to this?
Is there an updated replacement for the Web Developer add-on? I rely upon that for my work.
