Ever since the release of Firefox 66.0.0 a strange bug appeared which Mozilla can't cofirm, which makes me think the problem is with FVD Speed Dial: when I wake the computer up and Firefox is running, the whole interface disappears and I have to restart the browser in order to fix it. I made 2 screenshots - one with the normal interface: https://i.postimg.cc/V6mVDkg5/normal-look.png and one with the missing interface: https://i.postimg.cc/HLQNwyQf/after-waking-up.png

At first I thought it was a Firefox bug considering the address bar and the whole browser interface disappeared. But neither Mozilla or any other users can cofirm it as a Firefox bug, so the only possible explanation is that the cause of it is FVD Speed Dial. I have reported it to Mozilla and now I'm reporting it to you, hoping that one of the two companies may fix it.

In case the operating system matters for the problem, it's Linux Mint 18.3 Cinnamon x64.

Three times in a few days - the restoration of dials. similar plugins work fine. It is probably worth removing FVD and using normally working plugins.

Result:

Premise: Installed EverSyncIE.application on Windows 10 Pro for Workstation with an Administrators account.

Resize group tab size in the top left corner. There is lot of space left and the current tab is too tiny. 

I keep getting the error application validation did not succeed unable to continue when trying to install IE SYNC on windows 10. Application.InvalidDeploymentException (HashValidation)

In Opera v58, clicking the + button next to a tab opened my FVD SpeedDials.  Now it opens the Opera SpeedDial page.  FVD still works if I use CTRL-T or right click a tab and select "New tab"
