Rated 4 out of 5 stars
Extremely helpful. The only problem I see with this addon is that, if you have it notify you with a popup whenever an LSO is detected, it slows down the system. If you find momentary pauses every few seconds while watching youtube vids, disable this option.This review is for a previous version of the add-on (22.214.171.124-signed). This user has a previous review of this add-on.
Thank you for the second review!
I think it's worth to mention that this special notification function is not enabled by default.
Enabling the function even triggers a BetterPrivacy warning, informing you about the implicit drawbacks of using notification. Please note that this option requires BetterPrivacy to frequently parse a usually deep branch of operating system folders. Firefox is not well designed designed to perform this job quietly as background-task - and there unfortunately is no other technical solution possible.
Knowing this for a long time and with this reservation, I finally decided to vote in favor of the many requests for implementation of the feature.
