The add-on itself is great and works like advertised.
However, enabling it increases memory usage drastically. I have quite a lot of tabs open, and with this add-on enabled, my RAM usage jumps from 1000 MB to 1400 MB. This is not a fluke, I've tested this multiple times by enabling/disabling this addon and restarting the browser, so even though I've actually used this add-on for years now, I can't recommend it.
