It's OK. as long as all of the tabs are loaded in Firefox (not asleep), this extension will suspend them to the mobile browser; for this I'd recommend a feature that refreshes all Firefox mobile tabs, if that is possible. My one biggest gripe is that it is lacking many features from the desktop version, such as the option to not open onetab at startup. Please add these, as it is really annoyong having the onetab page pop up whenever I open a link in Firefox.
