For finding things I just use search in Power Tabs. Filtering down usually leaves me with a list I can scan through quickly. When it comes time to clean up I cheat by using that as well - filter my tab list, then select individual or groups of tabs to close. Generally I'll start by closing all tabs from news sites like the NY Times and WaPo under the assumption that they're probably stale, then clear out a bunch of HN tabs, and most often then switch to digging through the github ones to see what's actually relevant anymore. StackExchange and Reddit tend to get slashed pretty hard as well. Basically filter, viciously select, then close and I can blow away a thousand tabs in a couple of minutes. The highest I've ever gotten was around 6000 on old Firefox for Linux and I did see some slowdowns then, but that was on a seven year old laptop.
