Welcome to Foxden

If you’re reading this you have probably just installed Foxden. If the Foxden window opened up too small, remember that in most operating systems you can double-click on the title bar of a window to make it full screen. Thanks, welcome, here’s how Foxden wants to help you live your life.

Foxden is a personal information radiator. It allows you to split Firefox into several panes so that your important information is always visible to you. You can have your email, calendar, todo list, bug list, feeds, news, whatever matters to you, all on one page.

Click here to open the Foxden tutorial in a different window so that you can experiment with the layout of this window.

Basic layout

In Firefox, select Tools, then Foxden, and finally Configure…. This opens the configuration window. Click the Add… button, name your new layout ‘Search Engines’ and paste this into the layout box:

rows http://www.google.com http://mail.yahoo.com :rows

Click OK in both windows, and in Firefox select Tools / Foxden / Search Engines.

You should see a layout like this:


Pretty simple, right? Try adding a different URL on a new row, between yahoo and :rows. That should give you three rows.


Between each pane there should be a bar you can drag to resize the panes. Firefox remembers their size for you, so next time you open Foxden the panes are as you left them.


Now try some columns. Paste this into the layout box:

columns http://www.google.com http://www.yahoo.com http://www.msn.com :columns

You should get this layout: foxden_3col

That’s all there is to the configuration language: rows and columns. Let’s start our information radiator.

Rows in columns, and so on

columns http://mail.google.com rows http://calendar.google.com http://reader.google.com :rows :columns

That should give you a layout like this: foxden_rad1

Not just http

Here is the setup I use every day:

columns rows http://mail.google.com http://calendar.google.com :rows rows columns file:///home/graham/Desktop/SCRATCH.txt http://www.tadalist.com/ :columns http://reader.google.com :rows :columns

It gives me this layout: foxden_gk

Notice the file URL. Foxden automatically makes any local file editable.

Try this:

columns rows http://www.google.com chrome://browser/content/browser.xul :rows ftp://mirrors.usc.edu/pub/gnu/ :columns

On the right is an FTP site. Any URL that Firefox understands you can put into Foxden.

Notice the chrome URL? That’s a Firefox internal scheme, and gives you a browser in a pane. Other chrome URLs you might want to try are:

    Thankyou for an excelent addon. I was wondering if it is possible to start a foxden window upon start of firefox so I don’t manually have to open it from the tools menu?

    cool…really nice and simple.

    One thing to request is can you have optional address bar so as to change thing runtime? i have few sites which works only in IE and i can’t use them with this on single page. though its technically site issue if i could change the url , i can have them on single page.

    Tools is really good. Vijay

    Love this, but I do have one question. Can I use the auto-reloader with Foxden? For right now, I want to use it to pick up logins for several games and in order to do that, I need the screen to be refreshed at least every hour.

    Thanks. It’s a great add-on.

    Hi Graham, Nice job, I use your addon as a IP cam viewer. But I would like to know hot to run this addon automaticaly with Firefox. Is it also possible to start Foxden in previous (or set) positions of rows an collums?

    I was (and am) excited with this Add-on to Firefox! It is something that I have been looking for for a while now.

    Some things I noticed:

    1. The Foxden screen can not be resized. It is either full screen or a very small window in the upper left corner. To change between those options I have to go to the Preferences dialog, make the change and then minimize the window and restore it. I guess that this may have something to do with the fact that the Foxden window is not really maximized, but simply resized progrmatically to the screen dimensions.

    2. I tried making changes to the layout via the Preferences dialog, and got a message wanting to know if I wanted to restore a crashed session. And that leads to…

    3. I used your example script: columns rows http://www.google.com chrome://browser/content/browser.xul :rows ftp://mirrors.usc.edu/pub/gnu/ :columns When I attempted to open a Bookmark (also with PlainOld Favorites) nothing happened in the Foxden window, however the selections I made were opened in the parent Firefox window.

    4. There appears to be a video problem when when minimizing the Firefox parent window to the Foxden window. I notice that the Firefox title bar will flicker for a approximate 1 to 1.5 seconds then the Firefox window will minimize. This seems to happen when you have opened a new tab from the Foxden window.

    5. As mentioned previously, no option to maximize a window within Foxden, no way to navigate (backwards and forwards), Foxden can not be resized, only one Foxden window can be opened. It would be nice if Foxden opened into a new tab within the currently opened Firefox window.

    I look forward to testing future version of Foxden!

    one very annoying thing right off the bat: preferences opens in new browser window instead of tab or pop-up. when you have a lot of extensions this is really impractical. takes forever to load.

    also the lack of context menu, and all extensions disabled are huge negatives.

    in trying to post this comment i come upon another pretty unbelievable flaw. in adding the numbers (in text) i entered the sum in text. seems logical. but the answer was rejected. then i’m told to hit the “back button”, which doesn’t exist, and try again! backspace didn’t work, f5 didn’t work to refresh. i had to close it and start afresh. weird.


    Yup, agree with you about always opening a new window being impractical. I’ll have to look into that.

    Taking ‘forever’ to load is not Foxden, but the apps you put inside.

    The context menu is back in v0.2, grab it from here and install over the top of the previous version: https://addons.mozilla.org/en-US/firefox/addon/11363

    I tried the add-on and looks very nice. A little complicated for the common user though. I’d like to be able to drag panels once they’ve been created as to being able to reposition them. Good job

    [Graham] Yeah, being able to drag the panels would be nice, eh. That’s a serious improvement though, if anyone else fancies coding it, I’ll include it :-)

    All seems far to long winded to be of quick and easy use… could do with a friendlier interface.

    I really love the Foxden. I use it to have all my banking pages all together. My only regret is that I can’t figure out how to have 2 Foxden pages. I would also like to set one up to have all of my general daily productivity stuff open, such as email and chats and such that I leave up all day.

    Thanks for giving us the Foxden. I guess I am greedy and want more than one. :)


    [Graham] I can see how having several layouts could be useful. I’ll try and put that in a future version. Thanks for the suggestion.

    Ok I love it but here are a few major issues for me. No navigational abilities (back/forward). Most important to me is that I need to be able to zoom content. I have poor eyesight and most to all site’s text sizes are too small. The Reload button didn’t work but the Save function apparently did. Perhaps I need to try Foxden in a new Firefox profile? Extension conflicts?

    I can view my Desktop in a column, and I can view a .txt file, but how are you able to edit one in your configuration?

    All in all, this is a very cool extension. Please feel free to contact me directly to discuss the issues that I’ve noted or if you need help with future testing.

    [Graham] Hi Ken, appreciate the feedback. It’s not extension conflicts, just the features weren’t there.

    Most of this should be solved in v0.2, grab it from here: https://addons.mozilla.org/en-US/firefox/addon/11363 (Note that auto-update isn’t enabled for Experimental addons)

    Editing a file in Windows doesn’t work, oops. I’ll have that fixed soon, thanks for letting me know.

    This is really exciting. I’ll give you more feedback after I “kick the tires” for a while.
