Open With


This extension displays a list of your browsers on your menus and toolbars in Firefox. Clicking on them takes you to the page you're looking at in the browser of your choice.

Open With will attempt to find other browsers on your system. You can add your own entries, or hide them, using the options tab (visit about:openwith, or click the options button in the Add-on Manager).

Here are some examples of places you can add Open With to your Firefox:

Menu Panel


Developer Tools


Released versions can be downloaded from https://addons.mozilla.org/addon/open-with

You might be here because you'd like to see Open With in your language. Great!

To translate, you can:

  • Fork the Git repository, translate, and send me a pull request. Some knowledge of creating Mozilla add-ons is required.
  • Or, visit the project's page on Zoo, a website for add-on translation. (Please note that Zoo is under development, and could break at any time. It's mostly stable though.)

Contribute code

Want to add some functionality to Open With? Feel free to send me a pull request.

To get a working version of this repo in your Firefox profile, clone it into your extensions directory as openwith@darktrojan.net and start Firefox.

cd [your profile dir]/extensions
git clone git://github.com/darktrojan/openwith.git openwith@darktrojan.net


Releases are made from the master branch, except if a major version has its own branch for bugfixes, such as v5.5. Previously there was an unreleased branch, but I've removed it.


Each version I upload to AMO is tagged with a version number. Some things tagged with a version number are not on AMO.

Contribute money

Add-ons are available for free, but developing and supporting them does take a considerable amount of time. Please consider making a donation to help me pay my bills. You can contribute any amount you like through PayPal via addons.mozilla.org. (Note though that for amounts smaller than about US$1, PayPal takes most of it.)

You can also send BitCoin if you prefer. See the same link for an address.
