[Windows] Open Firefox and Firefox Portable at the same time with TwinFox

[1]One of the coolest things about Firefox is that it’s available in both installable and entirely thumbdrive-based portable editions. If you’re a user of the portable version, however, you might find it annoying that you can’t run the installed version at the same time as the version located on your thumb drive. TwinFox fixes that with just a single click.

What is it and what does it do

Firefox does not like having multiple copies open at once. TwinFox fixes that, allowing you to open the previously installed Firefox copy alongside your copy of Firefox Portable.



Twinfox is a very simple program. In fact, it’s as simple as extracting it to wherever you keep your portable Firefox installation and running it instead of Firefox Portable. Twinfox takes care of all of the hard work, and lets you then open up another instance of Firefox, such as the one installed on your computer.

There’s only one catch with Twinfox. It doesn’t let you open up Firefox Portable after you’ve opened your regular Firefox installation–that is, you must run the portable version first. This is a minor issue, but is still something to be aware of while using the program.

Conclusion and download link

Users of Firefox Portable will absolutely love TwinFox and its ability to open multiple Firefox instances at the same time. Though not very useful for very many people, for those that use or want to use both Firefox’s standard installed profile and their own portable profile, it’s an immensely useful program.
