Save Link in Folder



This add-on/extension is no longer compatible with current releases of Firefox.
The code is based on Mozilla's XUL- and XPCOM-APIs, which are obsolete and no longer supported.

Bringing the extension back to life would require a complete rewrite using WebExtensions.
Unfortunately at the moment I can't give you any details on when (or even if) I will be able to accomplish this task.
I will look into it if time permits.

Thanks for your patience!

This extension helps you to quickly save links/files into different folders without having to click through your folder structure again and again.

Simply create your personal set of frequently used save-locations and access them via context-menu.
The folders can automatically be opened by your favourite file-manager upon downloading.
They can even be browsed within Firefox using a new toolbar-menu.

1.5.12 (2013-01-17)

  • Again, the previous version didn't work as expected. :-( ... sorry 'bout that. :-)
    I invested some more time in code-digging and testing this time. I'm pretty confident it'll work now.
    In case someone else developing extensions is experiencing problems with the saveURL- and saveURI-methods:
    Both of these methods require additional parameters since they're "privacy aware" now.
    Whereas saveURI requires a nsILoadContext-object, saveURL simply needs a document-object referring to the content.
    However, saveURL kept popping up a SaveAs-dialog (due to whatever reason); so I had to remove saveURL-calls completely and replace them with internalSave-calls (which by the way are "privacy aware" as well now *g*).

Hidden Prefs

Save Image in Folder offers settings which are not reachable via GUI but Firefox's built-in "config-editor" (about:config).

The following preferences can be set (Name | Default).


extensions.savelinkinfolder.nofilereference-filename      | 'unknown'
extensions.savelinkinfolder.nofilereference-fileextension | 'ext'
extensions.savelinkinfolder.nofilereference-showdialog    | true

When you try to save an image that has no direct source-reference (e.g. these nasty php-linked images like then you'll automatically get prompted with a "Save As..."-dialog.
These preferences allow you to change the default-filename of the image to be saved; which is "unknown.ext".
You can even disable the "Save As..."-dialog by setting nofilereference-showdialog to false. That way your usual folder-settings will take effect. So keep in mind that if you have chosen to overwrite any existing files without prompting (for example)... you won't get prompted and the file will be overwritten... even if there might have been problems retrieving the actual image!

An extra for the even more advanced users ...
Now here comes a tricky (but very comfortable) way to get a characteristic filename for those parameterised download sources.
Assuming the source of the image reads like this:

You might want to have the threadid and attachmentid to be part of your image-filename.
Just enter something like the following into your nofilereference-filename-preference (mentioned above):


The resulting filename (including your preferred file-extension) will be:


Well... you still have to know the parameters in advance and decide which ones to use. So this isn't a very generic way dealing with the problem since it might not fit for every website. To keep it flexible and "universally usable" I also introduced a variable called ALL_PARAMETERS to just insert all parameters.


... will bring you ...


VoilĂ ! Hope anybody out there finds this useful.


extensions.savelinkinfolder.randomstring-length | 8

Determines the length of the random-variable (see "Prefix / Suffix Variables"-section below).


extensions.savelinkinfolder.doubleclick-minwidth  | 0
extensions.savelinkinfolder.doubleclick-minheight | 0

This sets the minimum width and height of an image when using the doubleclick-feature. If the double-clicked image is smaller than these values it won't be saved. This option prevents "accidental" double-clicks on navigational images (arrows, buttons, etc.) which shouldn't be saved. (Leaving the default setting 0 / 0 completely ignores the restriction; saving every image that gets double-clicked.)

Prefix/Suffix Variables

These variables can be used for the prefix/suffix-string:

Variable Description
%dd% day
%MM% month
%yyyy% year
%hh% hour
%mm% minute
%ss% second
%url% full address of the visited website (e.g. "www.mozilla.org_products_firefox_")
%domain% just the domain of the website (e.g. "")
%title% title of the website
%guid% a "globally unique identifier"-string
%random% a random number (length can be set in "Hidden Prefs")
%clipboard% the current (textual) contents of the clipboard


Q: Is there a way to export all folder-settings so that I don't have to reconfigure them when I reinstall my system.

A: Yes, there is. Like pretty much every other extension out there, Save Link in Folder saves its preferences directly into Firefox's preference-system.
Just open Firefox and type about:config in the address-bar. Then type extensions.savelinkinfolder into the filter-box. You then should see all settings for Save Link in Folder.
Just copy the preference named extensions.savelinkinfolder.folders into a text-file. Now you have exported your folder-settings. Later on you can use this method (the other way around) to import as well.

Q: Some links can't be saved. A dialog showing "unknown.ext" pops up. What's this?

A: Please check the "Hidden Prefs"-section on this page.
