there's loads of software to detect loss of connection
but what about when your connection is down?
Answer: Something basic - a sound alarm when connection is restored like a ping to a url e.g. your service provider
(ok, a modem/router/pc may need booting - but sometimes not).

As a long term user of v1 i've just tried v2 for the first time and memory use is 16348k (no plugins)
v1 is sitting at 896k
For a non keyboard maniac a simple bloat-free launcher is all i need - so back to v1 - it's perfection for me !
So save the download link for v1 (renamed lite?)

99% of the time i have links, searches, etc auto-open in a new tab, I find it really annoying that i have to repeatedly manually close the Untitled tab to save on screen space.
I use Tab Browser Preferences and ideally it should detect a spare tab and use it.

What is necessary is when a new tab is added then a check for existence of an untitled tab would delete it

Not seeing any solution with a sendkeys type script, I'm toying with the idea of writing an addon myself but it's time ...
