Compiling Pale Moon web browser on Fedora 27



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:

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

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

Using Google Talk Plugin in Palemoon Portable in Wine on Linux


My main browser is Palemoon Portable which I run in Wine on GNU/Linux. I also use Gmail, Google Talk (the pre-Hangouts tool), and Google Voice.

In order to make and receive phone calls from my main web gmail page, I used this process.

  1. Install Adobe Flash Player for Firefox on Windows. I used the offline installer from the download link at Weblink 2.
    1. Used my Linux native Firefox to navigate to the normal Adobe flash player download page.
    2. Selected “Need Flash Player for different computer?”
    3. Selected Windows 7/Vista/XP and FP 25 for Firefox – NPAPI.
    4. From a terminal, I ran the following command and installed Flash like ~/Downloads/install_flash_player.exe
  2. Install Google Talk plugin.
    1. Unfortunately the gmail link for “Download voice chat plugin” failed to complete. When I ran wine ~/Downloads/GoogleVoiceAndVideoSetup.exe from a terminal, I observed that the process failed because of some network issue related to wine:fixme:secur32:schannel_get_cipher_algid unknown algorithm 23
      fixme:secur32:schannel_get_mac_algid unknown algorithm 200

      I bet it has something to do with the way my GNU/Linux computers always have some long MAC address in my dhcp list instead of a normal 12-character value. I don’t know how to fix that, nor was I able to trick the installer to continue.
    2. So I had to install the Google Talk plugin manually.
      1. I used a Windows computer that already had a working environment of Google Talk for Palemoon Portable. I copied these files:C:\Users\bgstack15\AppData\Roaming\Mozilla\plugins\npgoogletalk.dll
        To location
        Where /usr/share/PMP257 is my D:\PortableApps location.
      2. I also copied this entire directory:C:\Users\bgstack15\AppData\Local\Google\Google Talk Plugin\
        As the directory
        /usr/share/PMP257/Lib/Mozilla/Plugins/Google Talk Plugin/
      3. I set up the wine registry with a key and values from a registry file as seen
        touch "${tf}"; chmod 0644 "${tf}"
        cat << EOF > "${tf}"
        [HKEY_CURRENT_USER\Software\Google\Google Talk Plugin]
        "install_dir"="z:\\usr\\share\\PMP257\\Lib\\Mozilla\\Plugins\\Google Talk Plugin\\"
        regedit "${tf}"

        If the registry file does not import properly, try sticking a blank line after REGEDIT4. WordPress and the html <code> tag do not play nicely together with blank lines in code.


This entire process was made possible by the fantastic users of the community: portablealpha, taosk8r, acamp, and robertcollier4. It was that one page (weblink 1), and my working but disused Windows installation that made this whole process possible.


I realize I make life hard for myself, for using a web interface in a portable version of a small fork of a web browser in an emulator.

The story behind why I use this portable browser, in wine, on Linux, is this. When I first started getting on the Internet, I was a teenager and did not own my own computer. I had a flash drive, and I used it to store my personal files. I discovered PortableApps which let me use probably Firefox 2 or 3 from my flash drive. Even as I grew and got my own computers, I still kept my main web browser as a portable one so it would be relatively free from OS hooks so it was easy to transplant from system to system, as I migrated my main workstation. I built up a new installation every couple of years, hopping from Firefox 17 at one point to 27 to 33 to 38. After that, I switched to Palemoon 25 Portable and that is what I’m still on as of this post.

Now, 2016 was the Year of Linux on the Desktop for me, as I wanted to avoid the Windows 10 debacle. I had installed Korora 22 Cinnamon on a spare laptop in November of 2015 and from there made it my main system. In February of 2016 I copied over my Palemoon Portable install and it ran in Wine just fine! The only problem it had was it didn’t work with Google Voice.

This week I was trying to solve a VLC dlna problem where it was not finding my Plex server. I got frustrated with that (a bug that’s still unresolved and transitioned into looking into the Google talk problem on Palemoon Portable.

Adding Google Voice plugin

Just wanted to let people know how I got the Google Voice plugin to work so that I could use the “Call Phone” feature from within gmail. This is *not* elegant but it’s the only way I could figure it out because the target computer is behind some nasty firewalls (and the Google Voice installer isn’t allowed to call home to download its files).

1. Install the Google Voice plugin on your home computer.
2. Locate the Google Voice and Video Accelerator plugins in FF using about:plugins.
3. Copy those to your Firefox Portable plugins directory on the flash drive.
4. Locate the “Google Talk Plugin” folder on your hard drive and copy it to the flash drive (doesn’t matter where).

When you want to use Google Voice through Firefox Portable, run the exe in the Google Talk Plugin first, then start FFP and go to gmail. Note that once you exit gmail, it will stop the exe, so you’ll have to run it again manually if needed.

Anyone have any suggestions to automate this?

Oh good

I found this thread again.. I cant seem to find where ff 4.0 puts these.. the info I get is:



Is this even still relevant?

Works like a charm!

You have to search your computer for those two files (real pain in the ass on newer windows machines because they try not to display any scary system files). Once windows can’t find it, click advanced, check include non-indexed, hidden and system files.

You also need to search for the folder “Google Talk Plugin” and copy that to the flash drive. It contains the executable that needs to be launched before Firefox is opened

Works without needing to load the EXE manually

Create the following directory structure if not already existing:

Place the following files/folders in Plugins directory:
“Google Talk Plugin” (complete folder)
“Google Talk Plugin Extras” (complete folder)

The files are located at:
DocsandSettings\Username\Local Settings\Application Data\Google\Google Talk Plugin\
DocsandSettings\Username\Application Data\Mozilla\plugins\

Then it will work and the EXE will automatically load from Gmail.

Specify path in registry to load EXE automatically

Hi – there is one update. If you want the EXE to run automatically, you must add the following registry key with the proper path to googletalkplugin.exe so that it knows where to find it and load it automatically. It will work without adding the registry path – but if the registry path is not there as shown below then you must run the googletalkplugin.exe manually before loading the browser.

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Google\Google Talk Plugin]
“install_dir”=”D:\\FirefoxPortable\\Data\\Plugins\\Google Talk Plugin\\”
