In the case of IHG, I asked in the forum if it could auto update and the unofficial response is that it isn't coded to auto update and is manual update only.
For Nano Defender, it says in the "Installationn" section
> You need Firefox version 58 or above to install this extension.
so it isn't compatible with WF 56.
Humm.. I installed Fennec and then this add. It shows in addon list but no way to use it.
Did you tried installing this one. Its an older version In fennec says addon corrupt https://imagehostgrabber.com/download.html

Thanks for taking the time to post here,
> 1.7.4.c, please use that. XPI located on site.
https://imagehostgrabber.com/download.html lists apparently inferior 1.7.0.4c and https://imagehostgrabber.com/IHG/imagegrabber-1.7.4c.xpi is 404 not found, was 1.7.4.c a typo?
FYI IHG has decided to only support Palemoon
Through a little trial and error I found the download link for 56.2.14 https://storage-waterfox.netdna-ssl.com/releases/win64/installer/Waterfox%2056.2.14%20Setup.exe
#1 and the hard stop is:
​
Image Host Grabber aka IHG.
​
​
I use it to suck up images. No IHG. ... Not usable.
​
None of the other similar are ported, and they can NOT be ported as the API(s) used are not available.
