Quick warning to all the folks here praising OneTab. The extension is wonderful for easily, quickly saving, importing and exporting tons of tab links, but for me at least, it has crashed more than once over a couple years of use and completely erased all the links I had saved to it.

I learned to periodically export all my OneTab links in the extension's export option and save them to text files named by date range. I'd suggest the same or similar to anyone using OneTab and obsessive about saving tab links.
