Describe the issue

• FF56 (windows 7), uBo 1.14.10 (note I just updated from 55 and 1.13.8->1.13.10->current, restarted etc)
• On about:newtab the panel shows my default settings including blocking remote fonts no-remote-fonts: * true - see the red X lower right. Note the uBo icon is greyed out. This is recognized as newtab.about-scheme in uMatrix
  
• My actual newtab page is a speed dial that is recognized as speeddial.chrome-scheme in uMatrix [note the extension I use is Speed Dial [FVD] which is currently legacy but they have a chrome version which will be coming to AMO]
• this is how uBo handles .chrome-scheme - note the red x missing on remote fonts. Also note the uBo icon is NOT greyed out
  

to reproduce

• Create a nilla profile
• Install uBo
• Install Speed Dial [FVD]
• Set no-remote-fonts: * true
• open about:newtab and click on uBo icon - note red X across remote fonts
• open speed dial home page - note red X missing on remote fonts

I looked but did not find anything similar lodged as an issue. Apologies if one already exists. I also do not know what else loads a *.chrome-scheme, and once FF57 lands, this legacy extension will be updated to a web extension, and I do not know what that will use. If this is not that important (eg its just because of my extension), then close it and I will see what happens after 57 :) Thanks
