Как я понимаю, в этих файлах хранятся настройки и если я захочу перенести свои кнопки на другой профиль, надо туда скопировать эту папку целиком?

Project/Feature Name: Necko Predictive Network Actions
Tracking  ID:881804
Description:
This project allows us to speed up page load time by "getting the boilerplate out of the way" when we're confident what the boilerplate will be for a page load. This means one or more of: resolving DNS, performing the TCP handshake, and (where applicable) performing the TLS handshake. This has the potential to save 100ms-multiple seconds on a page load, depending on the user's configuration, internet connection, and the page being loaded. We predict in one form or another on the following events:

*Browser startup (what pages does the user usually hit immediately after starting the browser?)
*Pageload (when you load this page, or a page from this domain, what subresources or domains are very likely to be used?)
*User hovers on a link (hovering on that link? you might be thinking about clicking!)

This is inspired by chrome's predictor: http://www.igvita.com/posa/high-perform … #predictor (note that we are not yet implementing "resource prefetching" and "page prerendering" in the table of techniques that chrome currently uses).
