User Reviews

Great in theory. Okay in practice. Unreliable in the long term. I've lost track of the number of times that large number of tabs get moved to a random group, or all moved into a single group. Sidebery was the initial reason I switched to FireFox/Zen, but I'm done with the extension now. Really disappointed.

Works beautiful in Zen, when also loading the according Zen mod/theme. Just one thing: when using the compact mode, on hovering, the whole Sidebery interface is darkened (which is not the case when not using the compact mode). I would like Sidebery to retain the Zen theme color. Thank you for your work :)
