Hi, Before upgrading to Quantum there was an add on called Move Tabs. With this rewrite it doesn't work and wasn't built into Quantum. I really need to have this functionality (basically with two keys, that you selected in setup, you could move the selected tab to the far right or far left. Can this be added to Quantum or will some brave soul write a new add on? To me it is very disappointing that Firefox gets upgraded and things like this are lost. Also Quantum with the latest upgrade is slower that the previous version at least for me. Thanks
