Disable auto update for firefox extension

Hi. Could anybody tell me how to disable the automatic updates for the firefox extension? I’ve been struggling with some macros using the new version, and I need to keep using them as those macros are part of the workflow of my department. These days I’ve been downloading the older versions from the webpage, but it automatically updates every day. I would really appreciate any info on this topic.

Hi, please see the screenshot:

Firefox makes disabling auto-updates very easy, while Chrome and Edge do not allow it.
