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

This is a brilliant add-on. As mentioned in one review, it is sometimes affected by changes to the parkrun website and the developers have to play catch up. They are as swift as they can be under the circumstances. I suspect that most folk who can't get their add-on to work have an ID-10-T problem rather than an issue with the extension.

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.

A great extension that enriches the basic parkrun data with additional information and challenges. As the developers aren't part of the parkrun team, sometimes changes to the website cause problems for the extension, but they usually get fixed fairly quickly.

This extension was marvellous until a couple of weeks ago. All of a sudden it's not showing the maps, or the various challenges & is only showing my name, 2 generic badges (100 & volunteer), Most recent parkruns, event summary & volunteer summary.

I want all of my challenges back!

I've been using this extension for about 3yrs now & have been using Firefox the entire time, but now I don't have any of the functionality that I used to have. I'm very disappointed.

I have Firefox installed on my Android phone solely to use this extension - it's that great. I really enjoy being able to access the stats, badges, and (my favourite) the map of parkruns visited which is always challenging me to fill in a 'hole' or extend the green visited area a bit further.

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

Fabulous extension, which used to be used by many parkrunners, particularly tourists, but sadly isn't compatible with current Android versions of Firefox (since v. 68.11.0, I think), all because Firefox dropped support for all but a few extensions. I've refused all subsequent Firefox updates since then so that I can continue to use the extension.
Fingers crossed Firefox do the decent thing!

Fantastic addition to all things parkrun
