My original review was good but after a windows 10 update KB4023057 (has its own problems) and the Firefox update to 64.0.2 I had 2 problems, the cursor racing across the screen which appears to have gone after I removed the Win 10 update but this extn keeps crashing and when I restore the tab it also does the same thing, very frustrating and still not sure where the probIem is, but it means I have to close the tab and start again, so all I have are my sites all on the tab but tolerate the crashing.

I missed the old when FF messed around with 57 and gave me 9 tabs + suggestions. Just had a windows update, which messed up again and coincided with an FF update which wiped the old 9 tabs and my entire history!. This new one now works fine although I am having trouble with the tile displaying the icon, I wish the drag/copy was an option and also, just for me, a pin tile so I don't hit the unpin and have to start again.
This is pretty close to the pre 57 version and with a bit of tweaking will be just as good.
