Grammarly and browser used

[gunhilltrain]

I had an old Dell computer that had both Firefox and Chrome - I added Chrome later. I had Grammarly on Firefox and continued to use that version, about the only thing I continued to do in that browser. About three years ago, I added Grammarly to Chrome too, and tried a handful of documents as experiments.

Now that I have a new computer with only Chrome, I can only see the experiments. Would I have to add Firefox if I wanted to see the stuff I had been working on recently? In other words, are Grammarly versions tied to a particular browser?
