Assuming that you were referring to my suggestion, yes and no: I started a new profile on my wife's computer a short while ago, after removing Zemana, as discussed in another thread, which fixed the problem of my Fx UAS being changed when rebooting.
The first thing I did was to copy the Extensions folder into the new profile; unlike what I found on my computer when doing that, I did get the bothersome set of tabs, so I decided to see what would happen if I closed all of the tabs before doing anything else. That done, I opened the Add-oms Manager, and there I found all of the extensions there in disabled mode. The first one that I enabled was one that I had, in an earlier new-profile creation, opened from its tab, and which failed to show its icon; when I enabled it from the Add-ons list, the icon appeared. Several other extension-related icons failed to appear when I used the tabs, all of which were present when i started over in my profile and enabled from Add-ons.
Based on that, I would add to my suggested change that, if the tabs do appear upon Extensions folder copying, that the tabs be closed and the extensions be enabled from Add-ons;
