Can anyone please help me figure out why can't I access my multiple open Firefox tabs on my Widow 11 desktop unless I open a new tab, and then click on the three line Firefox app menu symbol, then select "History" and then go back? I don't even have to choose a function under "History". I just go back to the tabs and they have become available to be selected and activated. This fix is only temporary and may have to be repeated several times in one session. The misbehaving tabs show up in a horizontal row over my toolbar area (sometimes as dark panels after an update) but clicking on them just causes the row of tabs shown, or the vertical list of excessive multiple tabs, to disappear. I tried selecting troubleshoot mode, but did not see any indications of errors. This problem only began after my last Firefox update and does not go away after a Windows reboot.
