Usually when I Mouse-over my Firefox Taskbar icon. I can preview (EACH WINDOW opened) w/ ("Tab Previews") to know what each windows contents are quickly!! I had a total of 8 ("Tab Previews") available previously to use and if I went above 8 it would start to stack at 9. This ("Tab Previews") Feature really helps to know which window is which and it saves time! I always wished I was able to have more then just 8 windows open. Yes anyone is able to open more then 8 Windows but.... If I go above 8, it (Stacks them all) vs (tab Previews). Then I have no idea where or what each windows contents are! <sad face> . Today I was updated to (Firefox 43.0.3). Now i only have (4) (tab Previews) available or it stacks at window 5, and they are Twice the size? Why? I love Firefox and do NOT want to use any other browser, but I might have no choice if I do not get this fixed. Pls help... Would someone anyone be so kind as to assist me with this problem? On how to correct the amount of (Tab Previews) I have. 4 is of no use to me. I need 8 or more. I need someone to inform me on how to make the amount of (Tab Previews) higher? . Ps...Coincidentally same day... A technician added a NEW USER for me and deleted my old User account on Windows 8.1 on the same day. Perhaps some setting may have been changed? I have this setting to save me time. <br>In Taskbar Properties: Mine is set to: (Always Combine Hide labels) I saw someone else wanted the opposite of me and wanted (Never combine) to have them all listed on their Taskbar Properties. I wish to be able to mouse over the Firefox icon on my Taskbar to view ALL (tiny image/tab previews) of each open window to be able to discern which is which quickly. Now I only have 4 LARGE vs previously having 8. Pls help. Image is included of how HUGE these are and if i go over 4 it stacks at amount of 5... Thanks.
