It offers (almost) everything I need without any bells and whistles.

What I personally still miss is the ability to arrange thumbnails with empty spaces between them.

Really excellent. I came from over a decade of using Opera and making great use of their native speed dial feature, and built a huge library of bookmarks there which I got very used to using daily. Out of the options available on Firefox, this one has met my needs and dealt with the imported bookmarks very easily. It's not as pretty-looking as Opera's native speed dial, but it's just one guy working on this extension versus an entire dev team that's been doing it for way longer.

Easy Speed Dial is also updated fairly often, and given great new features and customization.

The closest one to a native speed dial from Opera/Vivaldi. If you're migrating to Firefox from those browsers, this extension is a must.

В отличие от других отлично работает

Минималистично и полноценно... отлично.

can't resize dials. Dials are way too big.

That's a great expansion. It lacks proportional distribution of tabs on the screen. Fills the whole screen and you have to scroll. Zoom does not help due to lack of tab caption size customization. Please fix it.

Dial label seems way to small compared to text in box, it's out of proportion if I zoom in, other than that this addon is closest to Opera's function.

Bravo !

Can't set the bookmark directory (nothing happens when the button is pressed), so useless

Very good, clean dial. The developer recently wrote "The ability to add and edit bookmarks and folders within Toolbar Dial will be added in a future release". I will be waiting anxiously for this feature. Also, keyboard shortcuts to navigate back/forward between tiles and folders would be a welcome addition.
Congratulations so far!

This is the speed dial solution from vivaldi that I want on Firefox! I love it so far. If there's one thing I would like, is to pull a thumbnail from the site, or allow me to add my own.
