Where is the user manual?(AKA How do I configure dillo/How do I change the settings/What are the keybindings/Where do I change the start page/home page/search engine/panel/etc...)
Click on the '?' icon in dillo's control panel for the local help file. If not installed, it should bring you here.
What's the status of the dillo-3.x series ("dillo3")?This is the active branch.
dillo3 uses the FLTK-1.3 library.
What's the status of the dillo-2.x series ("dillo2")?dillo2 used the unreleased FLTK-2.0 library and is no longer maintained.
What's the status of the dillo-0.8.x series ("dillo1")?dillo1 used the obsolete GTK+-1.2 library and is no longer maintained.
What happened to the dillorc preferences for colors?CSS happened! To set colors, make a

How do I force web pages to use my favourite fonts with CSS?In your
Why isn't Dillo3 finding the font that I set?fltk-1.3 is somewhat more restricted in its use of font names than fltk2 was. Please try the fc-list command as shown in the current dillorc configuration file to find the right form of the fontname to use.
What libraries does dillo use?Dillo itself: Required: libpthread, libiconv, zlib. Optional: openssl, libpng, libjpeg.
FLTK: At least on Unix, the minimum might be X11, Xext, plus the default configuration also requiring Xft and fontconfig. OpenGL, exceptions, and rtti can be disabled since dillo does not use them.
The FLTK library is normally statically linked into dillo, so you would only need to get this library itself if you are building dillo for yourself.
Can I run dillo on directfb?No. (although Nikita Egorov did have fltk-1.1.9 working with directfb)
Internationalization and Localization (i18n & l10n)dillo's internal character encoding is UTF-8. It uses the iconv library to convert from/to other character encodings.
In recent releases, Dillo has improved line wrapping for Chinese and Japanese text, and also handles zero-width spaces, which can help with Thai, Lao, Cambodian, Burmese....
Scripts with right-to-left display (e.g., Arabic, Hebrew) or complex rendering rules (e.g., Arabic, Indic scripts) are not displayed properly.
The current Dillo developers use Latin-1 languages, so i18n testing and commentary would be particularly valued.
Why do some pages look strange?In part because the CSS 'float' property is not implemented yet (it is our top priority).
In the lower right corner of Dillo you'll see a bug-shaped icon. This is Dillo's bug meter. Click on it to see the HTML errors that have been detected.
Any HTML parsing patch should be backed up with information from the HTML 4.01 spec. Note that previous HTML specs can be considered as well.
Unfortunately, despite our respect for standards, there're some cases where it's impossible to change the Web's status quo; in those cases we follow Firefox and HTML5.
What does "bad font: variable" mean?When FLTK2 (used by Dillo2) is configured with XFT disabled, it expects "variable" and "fixed" to be listed somewhere in your fonts.alias files (and furthermore to be aliases for fonts that you have :). (an example)
Dillo2's rendering is badly broken for me. What do I have to change?You're getting blank regions in the window, and much of the text is being drawn in the upper left corner?
If you configured FLTK2 with --enable-cairo, there's your problem. Don't do that :)
OSX users: Dillo3 builds and runs native in it.
Why doesn't Dillo display certain images?
How do I enable cookies?(AKA Why can't I log into [some site]/Why can't I stay logged into [some site]?)
For privacy reasons, Dillo runs with cookies disabled by default. Cookies.txt (also available in the tarball) explains why in more detail.
Configuring cookies in Dillo is easy. Something
like the following inside
How do I clear/remove/delete my cookies?First, stop your plugins (dpis) with the following command:
The cookies dpi will write any permanent (ACCEPT) cookies to disk, and temporary (ACCEPT_SESSION) cookies will be discarded as the dpi exits.
Second, get rid of the permanent cookies by removing or editing your
How do I enable the https (SSL) support plugin for dillo?First of all, beware that this is a prototype in alpha state. It will only provide for very basic web page retrievals, POST and GET. There is no certificate caching and NO AUTHENTICATION performed.
It's disabled by default.
If you want to enable it (e.g. to read forums in https), then use
./configureThen recompile and reinstall.
If you want to help us to improve the plugin, please let us know!
How do I use a proxy with dillo?For HTTP, either set the proxy in your ~/.dillo/dillorc configuration file or set the http_proxy environment variable. To use a proxy with FTP and downloads, you need to configure the wget program that they use.
After upgrading, I get: "ERROR: dpi.c: can't start dpi daemon"The old dpid and some dpis may still be running. Just:
ps aux | grep dpid dpidc stop kill <dpid PID> ps aux | grep dpi kill <dpi PIDs>
Also: If you built dillo from source yourself, did you configure it so that 'make install' put dpid in a directory that's in your path?
How do I get started in developing Dillo plugins (dpis)?First, read "doc/Dpid.txt" and then the Dpi1 spec for details. The easy way to get started is to think of them as CGI programs that don't need a web server, and that provide some handy extensions. Dillo comes with several dpis. Play for a while with the bookmarks in dillo (it's implemented with a dpi) to get an idea of what can be done. The hello dpi provides a simpler example ("dpi:/hello/world"). Downloads, FTP and HTTPS are also dpi programs. Choose one of them and start to make some modifications. Remember that a dpi is an independent process that communicates with Dillo by using sockets. As an independent program, it has all the power the underlying OS provides it. For instance, it would be easy to modify the bookmarks dpi to provide for a dillo-based GUI for data stored in a DB server.
I have sent an email/patch/question/etc. to Jorge, but still no answer. What's the deal?Jorge has much more work than he can cope with. It's impossible to answer all the emails that pour in. There'd be no time for development, design, patch reviewing, patch integration, funding initiative, web site maintenance, quality assurance, release management, ...
So what do I do?
