I like this for several reasons. The first of which is that it has a cool customization option to allow automatic memory freeing. This is useful for "super browsing" habits-type folks like myself. When there are always multiple tabs, always multiple windows, and always memory-consuming processes taking place in those areas, an "auto-freeing of memory" is VERY useful. It's simple, just lets you enter a time in minutes. Similarly, the rest of this add-on maintains a consistent style of being simple, yet effective. It does, in fact, work, and if you don't believe it does, perhaps re-evaluate what it is you're trying to accomplish, or if memory-freeing is the right type of solution for your issue. This add-on has never NOT worked. Being the laziest possible enduser, I think this is the first review of anything, ever. I also find it inconvenient to merely type names and passwords, let alone donate. I made an account to write this review and donated one dollar, the suggested amount to make a point. When lazy people find one's work convenient and useful, it speaks to the effectiveness of the product being used. The review's called high-quality because this product is just that. Keep making add-ons!
