Firefox performance problems are often (usually?) caused by corruptions or misconfigurations in a profile. <br>

2. Migrate needed settings to the new profile and delete the old one<br>

For instance, recent versions of the JRE install a Firefox "quick start" plugin or addon, one or the other (I guess it's a preloader) which would affect Firefox startup time.<br>
