• System OS: Linux
• Firefox version: Firefox 109.0.1
• Textarea Cache version: 4.5.0

Description: When Firefox (v109.0.1) is launched, the following error is presented in Firefox's Multiprocess Browser Console due to the Textarea Cache extension:

 Error: Please use $(ref:runtime.getURL). ta_bg.js:169
    setupCacheList moz-extension://[UUID]/ta_bg.js:169

Please note this is listed as an error (not a warning). If I understand the error correctly, a small change to a single line of code should fix it.
