Problems with Firefox? You might need a new profile

Okay, so I want to begin by stating that I am absolutely loyal to Firefox and would never ever speak against it, but occasionally as with any relationship, there are a few “glitches”… I believe these occasional “glitches” to be solely related to the recent upgrade to Firefox 3 due to the fact that I did not experience these problems with previous versions. (I am basically using all the same add-ons just new versions which further points to the upgrade to 3 being the problem…)
