Does it happen constantly?

Hi,

We launched update couple hours ago. Update extension to the latest version:  62.8.5 or Higher
https://addons.mozilla.org/en-US/firefox/addon/fvd-speed-dial/

This is the simples option, not always help but we encourage to try. 

- Copy and paste in address bar about:support  
- Select following http://nimb.ws/Vm5pjy 
- Rename this folder to any name and restart Firefox http://nimb.ws/awxfuW BUT don't delete it. Just rename it, for example Storage_OLD

Here is VIDEO

If it won't help, let us know.

Wait till FF 57 will be released and reinstall the extension

What's your FF version?

К сожалению Мозилла разработчиков поставила перед фактом. Мы можите поставить более ранюю версию аддон и отколючит обновления.

Вам нужно использовать ФФ57, мы запустили новую версию.

в Текущей версии, откройте настройки  и сделайте бекап.  Обновите до ФФ 57 и востановите с бекапа.
