Recently I've noted that tabs on my browser move from where I had them all the way to the far right end of the tabs list, and it happens at random. There'll be times when I click on another tab while listening to music or a video on another only to find the tab I was listening to had moved when I go to click back on it. Without fail, I've found these tabs at the far right end of the set of tabs, and I need to know how to put a stop to this. It's inconvenient, and annoying in extreme. This has to be due to a recent update, because up til a couple months ago, this didn't happen at all. If there's a setting that I can change in about:config, I would like to know about it, because you can bet I'll disable this feature.
