I can no longer move tabs around, I already checked the existing advise, its set to 'true'

I haven't been able to move tabs around for days. Not since I tried to take some 'out' to make a new window, and Firefox straight up crashed ...repeatedly. After I gave up, I noticed the tabs no longer moved. I ignored it a few days, but its frankly very annoying! I checked for answers & found an old post from 5 yrs ago here & followed the advice. Or I tried to, but when I checked "browser.tabs.allowTabDetach" in "about:config" it was already set to "true". I even toggled it a few times (I even tried to see if it would move when set to false! ...counterintuitive, but I figured it was worth a try?) Anyhow "browser.tabs.allowTabDetach" is still set to true, and I'm not about to go monkeying with all that :\ (fair warning, while I know how to alter a config under clear instructions ...my experience with such things starts and ends with the config files for Stardew Valley mods) advice I found, which doesn't work/apply??- https://support.mozilla.org/en-US/questions/1302126
