With the update to firefox 53, snap links v2 stopped working on me. I installed Snap links plus. For some reason the initial explanation panel does not appear if you are not making a clean install (without snap links 2) so I thought for a long time that it simply didn't work.

After checking the comments here I found the config page ( http://cpriest.github.io/SnapLinksPlus/welcome.html ) and learned how to use the "lasso". It's better than nothing, but less effective than selecting different cells on a table -> right click -> Open on X tabs that you could use with the previous version.

When you right click to use the lasso, the contextual menu opens at the same time, which makes the usage less than ideal, then it opens the tabs automatically. Not bad per se, but for me it's a step back from what we had previously.
