can we get the Display in new tab option again?

Hi,

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. 

If it won't help, let us know.

I appreciate the reply but I have done that quite a few times yesterday, but that doesn’t bring back an option that disappeared in the updated FVD the “Display in new tab” option that allowed us chose if we wanted to always open FVD in a new tab or not, now its always FVD speed dial and no choice about it.  But I fixed it, refreshed firefox reinstalled all add-on except FDV and installed the Version 23.3.1 instead.

Thanks and sorry for my bad English.

Unfortunately, Firefox 57+ will automatically disable 23.3.1

Looks like you have only Option #2 or #3

We got many error reports, rolled back to the previous version. Just reinstall the extension.

Once we finish fixing major problems, we will launch a new update. Most likely you will have the same problem again.
You will need to do following:
Option #2 or #3

Unfortunately, you can't keep older version for a long because new FF57+ will automatically disable it. There is nothing we can do, that's how Firefox team implemented. 
We try to fix everything that is possible.

Highly recommend using EverSync to backup your dails.
