I don't know, how I can download GhostText for Firefox 49.0.2, so I did not have to reinstall GhostText at each session in Firefox.
Detail
I want to use GhostText. GhostText collaborator tell me, what addon on Mozilla site not worked and I need install GhostText manually. I need visit about:debugging#addons in Firefox →
click on Load Temporary Add-on and select the file browser/manifest.json inside my cloned project.
Now GhostText worked for me, but if I close Firefox, I need reinstall GhostText. I don't want reinstall GhostText each time, I want install addon one time and use it.
Did not help
about:addons → click on Settings button → Install Add-On From File. It is solution for .xpi or .jar extensions, if I select manifest.json, I saw Firefox message:
This add-on could not be installed because it appears to be corrupt.
I can not search other solutions in Google.
Thanks.
