Either it's too complicated for me to install this add-on or it just doesn't work. Either way it only gets 1⭐ for being unusable

I downloaded Firefox for Android specifically for this extension, only to find it's not compatible :(

Can't use it as mentioned in other reviews! Got the 5k app but would have been nice to have this so I could join in.

I only put Firefox on my phone so that I could use this extension. The grey Add to Firefox button does not work. So, I cannot use it. It doesn't work.

Doesn't work. Cant get started. Add to Firefox button doesn't work.

Why has this seemingly stopped being something that appears/works anymore? Update gone wrong?

Find it difficult to get this add on to my parkrun results

Doesn't work
