Translated with Google...sorry ^^

For me the first choice as a replacement for SpeedDial ........ actually!
My problem, it is unsuitable as a start page if syncronized Firefox with other computers. On all computers the extension has a different address ...
Eg moz-extension: //ff257a8c-77fa-4ca1-81a5-............/dial.html = Computer 1
Computer 2 is actually assigned another, eg moz-extension: //c229cd13-7104-7c45-a0da-............/dial.html.
However, Firefox-Sync sets all computers to one address as Startpage, which means you have to reconfig the home page on other computers.
But then you can do the same again on the next computer. An eternal cycle. A static moz-extension address would be appropriate

Update:

Thanks,

Simple and effective solution
The wide is often so close ^^

Have a nice day :)
