My husband was the computer expert - not me and he passed away four years ago. So please bear with me. Until two days ago I was able to open two Facebook tabs on Firefox web browser which is necessary for a platform that I do moderating for. Now for some reason I cannot and I don't understand why. I have tried to find the answer by searching and unable to resolve. Again, very much a novice at this stuff so any help would be appreciated. Thank you very much.
