Opening local files
Browsers block extension access to local files by default.
Follow the instructions below to allow links to local files from the new tab page.
Go to Manage Extensions > Details (or chrome://extensions/?id=mfgdmpfihlmdekaclngibpjhdebndhdj)
and enable "Allow access to file URLs"
Go to about:config and add the following string values:
| Name | Value |
|---|---|
| capability.policy.policynames | localfilelinks |
| capability.policy.localfilelinks.checkloaduri.enabled | allAccess |
| capability.policy.localfilelinks.sites | moz-extension://UNIQUE_ID_OF_ADDON_ON_YOUR_PC |
The last value should be the addon URL - this is different on every PC.
You can find the addon URL at about:debugging#/runtime/this-firefox
The final config should look something like this (except for the addon URL which is different on every PC):
