Options

Address bar

I like using the explicit searchbar. In my opinion Firefox must not search in the address bar nor do anything fancy.

Disable search

about:config
keyword.enable -> false

Disable domain guessing

I personally don't like the feature of prefixing entered domains with "www." and suffixing with ".com".

about:config
browser.fixup.alternate.enabled -> false

Disable fallback to https

When i'm testing something as a sysadmin, i don't want to change back the protocol from https:// to http:// manually on each iteration. Timeout -> fine, thanks. Don't try anything else.

about:config
browser.fixup.fallback-to-https -> false

Make sure these URLs match! You'll have to logout from firefox-sync to change this URLs once you change them.

Gopass Bridge

It's not the gopass from the repo https://www.gopass.pw/

   1 sudo aptitude install gnupg2 gopass-
   2 wget https://github.com/gopasspw/gopass/releases/download/v1.9.2/gopass_1.9.2_linux_amd64.deb
   3 sudo dpkg -i gopass_1.9.2_linux_amd64.deb

   1 mkdir -pv \
   2         ~/.config/gopass \
   3         ~/.mozilla/native-messaging-hosts
   4 chmod 0700 ~/.mozilla/native-messaging-hosts

Create a wrapper script for gopass
~/.config/gopass/gopass_wrapper.sh

   1 #!/bin/sh
   2 
   3 if [ -f ~/.gpg-agent-info ] && [ -n "$(pgrep gpg-agent)" ]; then
   4         source ~/.gpg-agent-info
   5         export GPG_AGENT_INFO
   6 else
   7         eval $(gpg-agent --daemon)
   8 fi
   9 
  10 export PATH="$PATH:/usr/local/bin" # required on MacOS/brew
  11 export GPG_TTY="$(tty)"
  12 
  13 /usr/local/bin/gopass jsonapi listen
  14 
  15 exit $?

Allow the browser extension to execute the wrapper script
~/.mozilla/native-messaging-hosts/com.justwatch.gopass.json

Burger menu > Settings > About Firefox > Click on Firefox Browser
