Okay, but I need your email adress for it (for privacy reasons)

Maybe I can hook up here:
Most of the time it works as you would expect, but more often than other times it does not. Either a new tab shows only a white page, or it looks like the screenshot here.



The message there says:"A website slows down your browser. What should be done?". With the buttons you can choose between "Stop website" and "Wait".
When this message comes up I see only my background-image, but no dials. If I click on "Stop website" the dials will also appear.

Sometimes I see only a white page instead of my dials when I open a new tab. No F5 or Ctrl+R will help, just restart Firefox or deactivate and reactivate the Speed Dial Addin.

Unfortunately this is not reproducible, so I suspect that Speed Dial wants to connect to some server when opening a new tab and this doesn't always work. Therefore,"Stop website" also causes the dials to be displayed as usual, because the attempt to connect to this server is abandoned.

These disruptions rarely last longer than a few seconds, but it still disturbs because it stops the workflow.

Good to know, thanks. I will then wait until I update to FF57. I need this browser because it's smart Autofill function. But I also need your Speed Dials!


By the way: if Mozilla's guys were smart, they would license Speed-Dial to you. For me, this is the AddOn that makes Firefox an unbeatable browser experience!

Thank you very much, this hint helped immediately. After that, there were not only no more update attempts, but also previously disappeared dials including their click numbers were available again.
You did a pretty good job!
