Firefox profile on a flash drive


I regularly use a computer at my workplace. This computer multiple people use so it is setup not to save Firefox’s settings. I use it enough, in specific ways, that I decided to find a way to use it with settings available.

I take a flash drive with me to be able to access various personal documents and programs. I had heard about web browsers being installed on flash drives; after I thought about it awhile, I realized all I would be required to do is put a profile on it.

The flash drive I have is formatted FAT32 to be able to use with Windows (my work computer) and I keep my flash drive organized similar to my Linux home directory for convenience. First I created a directory for the profile:

mkdir -p ~/.mozilla/firefox/profile/ANAME

Then I create the profile—from the command prompt this command will get the job done:

start firefox.exe -CreateProfile "MyName D:\.mozilla\firefox\profile\ANAME"


(Or alternately I could have typed firefox.exe -P from the start menu and used the GUI version.)

I started the profile then to have the necessary files created. After it got done loading, I quit Firefox and I deleted the profile managers knowledge of the profile but not the profile itself (see example picture).

With the profile created all required effort left to be done is to instruct Firefox of the profile’s location. I put this in a batch script so that I can regularly use it:

@echo off


set HOMEDRIVE=%cd:~0,2%

if exist C:\PATH\TO\firefox.exe start /b C:\PATH\TO\firefox.exe -profile %HOMEDRIVE%\.mozilla\firefox\profile\toddweed && exit

if exist C:\PATH\TO\firefox.exe start /b C:\PATH\TO\firefox.exe -profile %HOMEDRIVE%\.mozilla\firefox\profile\toddweed && exit

if exist C:\Program Files\Mozilla Firefox\firefox.exe (
  start /b C:\PATH\TO\firefox.exe -profile %HOMEDRIVE%\.mozilla\firefox\profile\toddweed
) else (
  echo Firefox executable not found.

GNU love for Windows


I wanted to be able to type in Windows with a familiar text editor. I downloaded a terminal text editor called gvim, which I think is a good text editor, and it was able to be installed portably—this last is necessary as the computer I use I am not able to install anything on. However, even with having that, I discovered that I wanted to be to use the GNU tools I had become familiar with… hence a dilemma.

There are several projects that provide GNU utilities on Windows… I have learned. I am not an expert in these mind you—I have tried only one—however, I’ve heard good things about them all. The following are all terminal emulators and they include the GNU utilities: Cygwin, Gow (GNU on Windows), and Git-bash.

I have only tried the later one. The reason for this is because I’ve had it already installed as it comes installed with the Git program that I use at times. I would have like to tried for the first two, however I’m not too picky and Git-bash has done me well enough; it has the basic utilities and is pretty much ready to go.

Having GNU utilities available is handy for me and saves me a bit of time because of familiarity; another bonus is time saved that would be required to learn the Windows command line. The tools run just like they do on Linux/Unix and can be used on the whole file system. Many of the tools are there: sed, awk, mkdir…. For example, I can type:

$ find /c/Windows/Web/ -type f -name "*Think*"

By default the terminal emulator uses the already set Windows %HOMEPATH% variable for shell’s $HOME directory—this is usually C:\Users\USERNAME. I decided to use my flash drive as the $HOME directory where all my documents and settings could be kept. I had to create a batch script that defined the %HOMEPATH% and then have it start Git-bash:

@echo off

set HOMEDRIVE=%cd:~0,2%

start /B %HOMEDRIVE%\Downloads\Git\git-bash.exe


I then created a shortcut to flash drive root directory for quick access and to have a custom icon. I icon I choose was taken from the git-bash.exe file when I was asked for the icon location.

Git setup

An error was the first thing I had to fix… and it may just be for my particular version of Git; it complained to me when I tried to use it and I had to specify the certificate location. I did this by:

git config --system http.sslcainfo /d/Downloads/Git/mingw32/ssl/certs/ca-bundle.crt

After this I added ssh-agent to my ~/.bashrc launch it:

# SSH agent auto-launch
# 0 = agent running with key; 1 = agent running w/o key; 2 = agent not running
agent_run_state=$(ssh-add -l >| /dev/null 2>&1; echo $?)
if   [ $agent_run_state = 2 ]; then
  eval $(ssh-agent -s)
elif [ $agent_run_state = 1 ]; then

And likewise I added to the bash_logout file ssh-agent -k as Windows would think that it was still running if I didn’t.

Now I’m working pretty good in Windows.
