I've had this for around five years until last week when the Galaxy function was empty. Then it stopped working all together. I have tried reloading FOE on Firefox, Google and Brave. The extensions install, but I can't start the game from the browsers and none of the tools show up. When it worked before, I would select the FOE-Helper extension and a drop down window would give me a FOE Tools that when selected, would start the game.
I am logged into teh FOE Helper web page and it shows my profile and worlds I play in. What step(s) did I miss?

For all those looking for the good old features, just downgrade to the old 2.4 version. Just scroll down the addon site until you get to More Information>Version History.

Slows down the computer, and the most interesting functions have been removed since the last update. No!
Fait ralentir l'ordinateur , et les fonctions les plus intéressante on été supprimé depuis la dernière mise a jour. NUL !
