Could be very good, but is so bug ridden that after a few days I just had to uninstall it. The bugs:

1) Keeps showing the tour on every start in Private windows, tabs, or if you have deleted your cookies.
2) Randomly displays text info below the dials... which pushes the dials up under the group bar.
3) Randomly reverts to default settings on either all, or some of the options.
4) Randomly opens up as a blank page, yet the "moz-extension://cd47a81f..." still shows in the address bar.

I could list more issues. Note that this occurs on Linux, WIndows 7, and Windows 10. Real bugs. And lots of them. Developer: If you want people to pay for premium, at least make it stable. One should not have to reconfigure your extension on almost every use. And, it needs to work with ALL types of FF settings.

New update open to Speeddial 2 webpage. No customization options. I'm sure it will get worked out. I love this addons my very best favorite use it on all my laptops... I have 4 for different reasons and loving it.
ALREADY FIXED.

Именно то, что искал, минималистично и функционально)

I have used this for a long time in Chromium, it's well worth getting the premium version if you want your dials to be synced across browsers.

Very Best

хорошее расширение. Не тормозит.

Awesome ! Can add many that are not listed. customization is great

really nice speed dial, but there are two bugs.

1. i have the speed dial set as my home page. after closing firefox and opening it again the speed dial does not show. i have to open a new tab to see it.

2. in ingocneto mode it keeps showing me the welcome tour (though i realise that may be a little more to do with FF than this addon).

otherwise, its really good.

"コンテキストメニューにSpeed Dial 2 を表示"が全く機能していないので直してほしい。
サムネイルを自分の好きな画像に変更できるようにしてほしい。
そしてもう一つ、アドオンの"Quick Dial"のように、ブラウザのブックマークが直接、スピードダイヤルに反映されるようにしてほしい。
これらが満たされれば、常用するに値するアドオンとなる。

每次打开浏览器都要重新跳过游览？

操作性・表示スピード等は良いがオリジナルのサムネ設定する事すら無料で出来ない。設定がすぐ飛ぶ。無料で充分他のアドオンで代用できるからアドオン停止しました。

Der letzte Mist. Setzt sich so nach jdem vierten bis fünften Neustart des PCs auf die Ausgangseinstellungen zurück und man muss wieder alles von vorne einstellen. 10 Tage gestestet, nach dem ca. 20.ten mal neukonfigurieren runter damit. Schade, dass das gute alte original SpeedDial für Firefox nicht weiterentwickelt wird.

I've been a user of this extension in Chrome for quite a long time but the Firefox version is rather broken. Many functions do not work normally yet, e.g. custom CSS.

Not bad extension but it doesn't keep user settings. After restart firefox, it again shows the tour, and appearance preferences are resetting.
