Firefox 45.01 Portable note: I choose When to update Firefox, because critical Addons are often effected For the last two versions (40 and 45), the Update Nag Pop Up appears Three (3) times First is a small white unobtrusive box in the bottom left corner Then there is the large centre screen grey dialogue box, which must be clicked away (see image) Then it appears AGAIN, random timing, sometimes the two are together, one on top of the other, sometimes they are minutes or hours apart in appearing (I question the need for the Large Update Nag at all, surely the small friendly, and most importantly - Completely Unobtrusive - one is more than enough? If I am wishing to update, this prompt will be enough, if I Do Not wish too, then further prompts are merely annoying [and they certainly ARE annoying]... ) (Extensions: Tab Mix Plus Tile Tabs URL Flipper Addons as standard) Cheers
