We have fixed this problem with high CPU usage, and we have submitted a new version of add-on to Mozilla on Feb/28/2023 for approval. Once AMO team approves it, you will be able to update to it. We have disabled 6.41.7 version in addons.mozilla.org. Please delete 6.41.7 version in your Firefox browser and install 6.41.1 that is listed as current in addons.mozilla.org.
