Can not display local image (ver. 2.0.2.8)

[sppmg]

Can't display local image file. Don't know which is last working version.

I tried relative path (with correct file location), but nothing to display. (Online image url working)

![01](01.jpg)
![02](./01.jpg)
![03](./img/01.jpg)

Also, can't click view Source on addon's menu.

System

• OS: Debian GNU/Linux 11 (bullseye)
• Firefox: 102.12.0esr（64 bit）
• Addon: Markdown Viewer Webext 2.0.2.8

Another addon include:

• NoScript
• uBlock Origin
  (But I don't see they block anything. NoScript show can't change authority, but I still try to click allow all in this page.)
