Total Suspender от k5md

A minimalistic web extension for firefox that suspends natively (with tabs.discard) all non-active tabs and requires only minimal permissions to store it's settings and filter URL's.
- Implements whitelisting feature. You can enter URLs or their parts to the corresponding field and the tabs, which url's contain these patterns will not be discarded. May be useful when reading manuals or browsing tubes.
- Can ignore tabs playing sound
- Implements delayed suspend feature
