Storage – MDC: Reason #846 why the Firefox extension architecture is friggin’ amazing.
Storage is a SQLite database API. It is available to trusted callers, meaning extensions and Firefox components only.
So, your extension can store its data in a local SQLite database, stored in your Firefox profile. Awesome.
SQLite, as we’ve discussed before, is a fantastic little, file-based relational database. Blindingly fast and crazy lightweight, it gets used in embedded situations all the time, but to let your Firefox extension create one and manage data in it really opens up some great things.
Like what? Zotero — one of the most exciting Firefox extensions I’ve seen in a long time (much more on Zotero later…).
