In v3.6 (and it looks like in v4.0 too), every time one clicks the Clear Private Data Now (using a toolbar button), a dialog box pops up to confirm that I indeed want to clear data and which data. Why?!!! Why can this be set like it was in previous versions where a person sets which data they want cleared and be done with it? It's annoying. As such, I've used a v3.0.## since this annoying pop-up began in v3.5 or v3.6 or whenever it was. And please don't ask, if I have it clear on close, why I want clear it during a browsing session. Just know that I do. And the fact that you have for a long time had the feature to clear during a session shows that you or someone thought it good to have this feature--not just when the browser closes. I'd like to move to the current version, but this is so annoying. I'd move to Chrome, but for a few reasons, I'd prefer to stay with Firefox. For the love of gawd, can you please fix this?
