Firefox Developer Edition doesn't work

Question

A few days ago I installed firefox developer edition by this method (downloading and unzipping the .bz2 file). That install worked well.

After some time Firefox notified me to update, so I deleted /opt/firefox and reinstalled it using ubuntu-make (umake). While doing so, I accidentally installed firefox by running sudo apt update firefox, so I ran sudo apt remove firefox to delete it.

When the umake install didn't work well, I removed ~/.local/share/umake/ and reinstalled it the first way. But it still isn't working as well as before the update. What should I do?

I'm using WSL.

What isn't working:

• minimize/maximize buttons are gone
• menu bar isn't working (every button in menu doesn't work)
• when I type something mouse cursor turn into black box

Answer 1

Try sudo apt-get purge firefox then reinstall by your initial method.

When following a guide to install a thing, it's worth considering it's instructions for the update process (step 7).
