UI is extremely slow, especially with previews enabled.

Pop-up only really limits the usefulness. A sidebar option would be great.

Very slow and takes forever to create previews. Has no progress bar so you don't know if each tab preview is loading, loaded, or anything. The window is too small as well.

Simple and to the point. No bloat and excellent add on.

Excellent extension. I quite like this feature: " save all tabs for later" and mostly the Preview of the tabs on the Left when you Hover-Over them! This is very handy! But you can see the tab's preview, only if the Tab is already Loaded. (If it is muted, you can not see the Preview). Also the number of tabs would be very helpful to be displayed. Fix this please and I will give all 5 stars! * I am also curious to know where do those tabs get save? in which folder on the PC? Because There is no Option to Create account with TABBY...

Because of the preview thumbnails, this is quite handy when you have a lot of tabs open and quickly want to look for a tab even if you don't know the name of the specific article or website off the top of your head.

However, the performance of the addon needs to be improved when there are a lot of tabs open because in that case the addon becomes super laggy.

Would be better if keyboard could be used to switch to tab. Currently I have to type to search for a tab, then switch to mouse, then back to keyboard. Having arrows work for navigating the search result would improve ergonomics.

How to save tabs for next time browsing ? no way there. just tabs and previews.

I love this Addon. It helps me every day with my lot of tabs!
It's fast and easy to configure, the preview is a nice feature.

But please don't forget a "dark mode" ;)

A pop up size is too small and inconvenient with my 600 tabs. Just consider simple task of moving 5 tabs from Window 7 to Window 13.
The app makes it impossible to handle.

Meh. Doesn't really do anything I can't already do with other extensions I already have. Additionally, the most attractive feature, which is the ability to preview tabs when hovering, is rendered basically useless since it doesn't show anything until a tab is actually loaded, and then only after you load it, move away from it, then return. Kind of pointless when FF default now is not to load any tabs until they are selected.
