Default: `false`.
After uBO 1.17.5rc0 - Chromium only. Firefox now uses ["persistent startup listeners"](https://bugzilla.mozilla.org/show_bug.cgi?id=1503721) by default.
If set to `true`, uBO will hard block all network requests when the browser launches until _all_ the filter lists and rules are loaded and ready, at which time uBO will force a reload of the tabs for which there were network requests blocked during the setup phase.
Disclaimer: even with this setting enabled (set to `true`), it's impossible for uBO to guarantee with 100% certainty that everything will be properly blocked when the browser is launched. **This is a by-design browser issue** -- do _not_ open an issue on uBO issue tracker about this.
