All of my Simple Tabs Group (STGs) tabs were reset in Firefox to 0. I had not cleaned them up in a while & had from 5 to 40 tabs saved in each of the 12 Groups created. In the past, I have had the problem of unknowingly opening a 2nd browser window (with no tabs open) & then closing my 1st (main) window before the empty one after I finished working, but I have always be able to recover one of my main tab screens. All of my other tab groups were still listed & available under the Simple Tabs Group logo beside the currently open web site address on the tabs bar (just below the top line of the open & available web sites). This time after I clicked the STGs icon, all of my Simple Tabs Group label names are still listed, but the number of tabs shown for each label shows "0". They have all been deleted. Does anyone know how I can recover this info??? I have regularly use Windows 10 bkup. Is W10 just in the process of a slow death?? It's certainly very bad time (Apr, '25) to need to buy a new PC with all Trump's tariffs.
