Absolutely love this extension, one of the bests ADD-ONS. Please Please update this extension. Tabzi does not load the previews sometimes now. @Developer When clicking the Tabzi icon previews are very slow to load or if at all when there are many tabs open, 20 or more. I am on the nightly Firefox build on Linux Mint 20.

Simple and useful with nice design.

very helpful & user-friendly

I open a lot of tabs when I work (and usually never close them). This add-on is extremely helpful and elegant to organize my messy tabs!
