Thank youuuuuuu. They really should include the ability to change keybindings by default in firefox.

Work perfectly. Does exactly what it says in the description

super helpful for linux users

Thanks a lot for making this! It helps a ton on Linux.

Very useful addon, I don't understand why Firefox don't use it by default.

As others say, it just works. This firefox extension perfectly solved my annoyance of needing to use Alt+Number to change tabs after changing to linux from windows. thank you devs.
