Uninstalling other fzf plugins

fzf.fish is incompatible with other fzf plugins for fish.

fzf's out of the box fish extension

Check if you installed this:

bind | grep fzf-history-widget

If there is output, you probably installed it when you ran its installer. Uninstall by running the uninstaller. It may already exist on your system. For example, the homebrew uninstaller is here:

cd (brew --prefix)
/opt/fzf/uninstall

If you can't find the uninstaller on your system, download the source and execute it locally.

jethrokuan/fzf

Uninstall with fisher remove jethokuan/fzf if you installed using fisher.
