I've come to rely on the XUL extension Load Tab On Select in Waterfox Classic, looking for a replacement for Firefox Quantum (83 / latest).
There are two candidates that I know of:
1) https://addons.mozilla.org/en-US/firefo ... onselect3/
2) https://addons.mozilla.org/en-US/firefox/addon/holdtab/
I'm not a coder but I think the original XUL extention was more effective, in that it appeared to block tab loading, rather than unload tabs, but even if that's true what can you do. So basically, since all such extensions require you to grant broad permissions, I'm hoping people here can recommend one over the other, trust-wise, or suggest another method? THX
