Compiling Pale Moon web browser on Fedora 27

<

Story

I like the traditional model of Firefox. This is easily represented in the current project Pale Moon. The upstream project does not currently provide instructions for compiling on Fedora 27. All the options they have documented are on their developer site: https://developer.palemoon.org/Developer_Guide:Build_Instructions/Pale_Moon/Linux.

You might think it is no big deal to download and compile an application. But when the application is still targeted for gcc4.9, it’s a little tricky to compile on the current Fedora which uses gcc7.

After consulting the Internet, I have assembled my instructions for compiling Palemoon on Fedora.

Compile palemoon on Fedora 27

# Install the whole set of packages listed on (primary ref 1) for CentOS7
sudo dnf -y install gtk2-devel dbus-glib-devel autoconf213 yasm mesa-libGL-devel alsa-lib-devel libXt-devel zlib-devel openssl-devel sqlite-devel bzip2-devel pulseaudio-libs-devel
sudo dnf -y groupinstall 'Development Tools'

# Install additional dependencies I found
sudo dnf -y install nspr-devel

# Use autoconf 2.13
autoconfver="$( autoconf --version 2>/dev/null | awk 'NR==1 {print $NF*100;} END {print "0";}' | head -n1 )"
test ${autoconfver} -ne 213 && test ${autoconfver} -gt 0 && sudo mv /usr/bin/autoconf /usr/bin/autoconf-${autoconver} 2>/dev/null ; sudo ln -sf autoconf-2.13 /usr/bin/autoconf

# Use the copr davidva/gcc49
sudo dnf -y copr enable davidva/gcc49
# fix the $releasever variable in the repo
sudo sed -i -r -e 's/-\$releasever-/-23-/;' /etc/yum.repos.d/_copr_davidva-gcc49.repo
sudo dnf -y install gcc49
# fix a minor library problem (primary ref 2)

sudo cp -p ../lib64/libgcc_s.so.1 .
sudo ln -s libgcc_s.so.1 libgcc_s.so

Future steps

Post these instructions on the fedora and palemoon fora.
Ask Pale Moon devs if these can be adapted and shared on Reference 1.

My best practice for html links

  • Don’t use target=”_blank” because that forces only one behavior, opening in a new tab. I should expect the user to open a link in a new tab if he wants to.
  • Don’t omit the referrer, which is done by including rel=”noreferrer”. I want other sites to know who is linking to them, in the hopes of getting cross-traffic.
  • Do include rel=”noopener” to protect users (reference 1).

Adding Reverse Proxy for Plex to Apache vhost

Introduction

It is easy to find apache vhost definitions for reverse proxying plex traffic.
What this post does is show you how to include the parts needed, to provide a reverse proxy to plex, in an existing vhost. Why would you need this? I don’t know. I did, and it was as easy as adding a few bits to represent the web address.

Adding reverse proxy for plex to Apache vhost

So in your vhost, add these lines:

        <Proxy *>
                Order deny,allow
                Allow from all
        </Proxy>
        ProxyRequests Off
        ProxyPass               /web/   http://www.ipa.example.com:32400/web/
        ProxyPassReverse        /web/   http://www.ipa.example.com:32400/web/
        <LocationMatch '^/web\/.*$'>
                RequestHeader set Front-End-Https "On"
                RewriteEngine On
                RewriteCond     %{REQUEST_URI}          !^/web
                RewriteCond     %{HTTP:X-Plex-Device}   ^$
                RewriteCond %{REQUEST_METHOD}   !^(OPTIONS)$
                RewriteRule ^/$ /web/$1 [R,L]
        </LocationMatch>

So the difference in this snippet from a separate vhost definition is that you proxypass only the /web/ location over to your Plex media server.
