It works very well, but sometimes activates itself without me doing anything. And opens huge amount of links I didn't wanted.

you could let us choose between opening automatically or after scroll click/popup icon left click after lassoing. Great extension.
Ps.: It opens the context menu each first lassoing.

It is fantastic and so handy. Especially that I can set it to only open links after a set time. I am not sure if it is possible but could there be the option to only open links you have not visited yet. For example on a site it shows the link go from white to pink because it is visited.
I obviously have no experience with that and would not know. I really appreciate this app though!

excellent software

Updating to Firefox 81.0 will disable the add-ons for version 3.1.7; reverting to 3.1.6 will make them work.
