Replace Firefox's default control mechanism with one modelled on the one true editor, Vim.
Simply click this link in Firefox to install our latest "beta" build. These betas are updated with each commit to master on this repo. Your browser will automatically update from there once a day. If you want more frequent updates, you can change
about:config to whatever time you want, say, 15 minutes (900 seconds). Alternatively, you can get our "stable" builds straight from Mozilla. The changelog for the stable versions can be found here. If you want to use advanced features such as edit-in-Vim, you'll also need to install the native messenger or executable, instructions for which can be found by typing
:installnative and hitting enter once you are in Tridactyl.
:help or press
<F1> for online help once you're in :)
Remember that Tridactyl cannot run on any page on about:*, data:*, view-source:* and file:*. We're sorry about that and we're working with Firefox to improve this situation by removing restrictions on existing APIs and developing a new API.
We can now run on addons.mozilla.org and a few other websites if you run
fixamo once you've installed the native messenger.
help fixamo tells you exactly what it does.
If you're enjoying Tridactyl, or not, please leave a review on the AMO.
Like Vim, Tridactyl is modal, with the default mode being "normal mode". In "normal mode", many functions are available using keybindings. In "command mode" (when the command line is shown), you can execute more complex commands, known as "ex-commands". All Tridactyl functionality can be accessed by ex-commands. You can bind any ex-command to a normal-mode shortcut. We also support a
.tridactylrc file, of which there is an example in the root of this repository.
Default normal-mode bindings
This is a (non-exhaustive) list of the most common normal-mode bindings. Type
:help to open the online help for more details.
:— activate the command line
Insert— enter "ignore mode". Press
Insertagain to return to "normal mode".
ZZ— close all tabs and windows, but only "save" them if your about:preferences are set to "show your tabs and windows from last time"
.— repeat the last command
You can try
:help key to know more about
key. If it is an existing binding, it will take you to the help section of the command that will be executed when pressing
key. For example
:help . will take you to the help section of the
Navigating with the current page
k— scroll down/up
l— scroll left/right
$— scroll to left/right margin
G— scroll to start/end of page
F— enter "hint mode" to select a link to follow.
Fto open in a background tab (note: hint characters should be typed in lowercase)
gi— scroll to and focus the last-used input on the page
R— reload page or hard reload page
yy— copy the current page URL to the clipboard
]]— navigate forward/backward though paginated pages, for example comics, multi-part articles, search result pages, etc.
[c— increment/decrement the current URL by 1
gu— go to the parent of the current URL
gU— go to the root domain of the current URL
gr— open Firefox reader mode (note: Tridactyl will not work in this mode)
zz— zoom in/out/reset zoom
<C-b>— jump to the next/previous part of the page
Find mode is still incomplete and uses the Firefox feature "Quick Find". This will be improved eventually.
/— open the find search box
<C-G>— find the next/previous instance of the last find operation (note: these are the standard Firefox shortcuts)
Please note that Tridactyl overrides Firefox's
<C-f> search, replacing it with a binding to go to the next part of the page. If you want to be able to use
<C-f> again to search for things, use
Bookmarks and quickmarks
A— bookmark the current page
a— bookmark the current page, but allow the URL to be modified first
M<key>— bind a quickmark to the given key
gw<key>— open a given quickmark in current tab/new tab/new window
If you want to use Firefox's default
<C-b> binding to open the bookmarks sidebar, make sure to run
unbind <C-b> because Tridactyl replaces this setting with one to go to the previous part of the page.
Navigating to new pages:
O— open a URL (or default search) in this tab (
Oto pre-load current URL)
T— open a URL (or default search) in a new tab (
Tto pre-load current URL)
W— open a URL (or default search) in a new window (
Wto pre-load current URL)
P— open the clipboard contents in the current/new tab
S— force a search using the default Tridactyl search engine, opening in the current/new tab. This is useful when searching for something that would otherwise be treated as a URL by
L— go back/forward in the tab history
gH— go to the pages you have set with
set home [url1] [url2] ...
d— close the current tab
u— undo the last tab/window closure
gT— go to the next/previous tab
g$— go to the first/last tab
b— bring up a list of open tabs in the current window; you can type the tab ID or part of the title or URL to choose a tab
Extended hint mode
Extended hint modes allow you to perform actions on page items:
;I— open an image (in current/new tab)
;a— save/save-as the linked resource
;A— save/save-as the selected image
;p— copy an element's text to the clipboard
;P— copy an element's title/alt text to the clipboard
;y— copy an element's link URL to the clipboard
;#— copy an element's anchor URL to the clipboard
;r— read the element's text with text-to-speech
;k— delete an element from the page
;;— focus an element
Additionally, you can hint elements matching a custom CSS selector with
:hint -c [selector] which is useful for site-specific versions of the standard
f hint mode.
Binding custom commands
You can bind your own shortcuts in normal mode with the
:bind command. For example
:bind J tabprev to bind
J to switch to the previous tab. See
:help bind for details about this command.
- Navigation to any about:* pages using
:openrequires the native messenger.
- Firefox will not load Tridactyl on about:*, some file:* URIs, view-source:*, or data:*. On these pages Ctrl-L (or F6), Ctrl-Tab and Ctrl-W are your escape hatches.
- addons.mozilla.org is now supported so long as you run
- addons.mozilla.org is now supported so long as you run
- Tridactyl now supports changing the Firefox GUI if you have the native messenger installed via
guiset. There's quite a few options available, but
guiset gui noneis probably what you want, perhaps followed up with
guiset tabs always. See
:help guisetfor a list of all possible options.
Frequently asked questions
Why doesn't Tridactyl respect my search engine settings?
It's a webextension limitation. Firefox doesn't allow reading user preferences.
Why doesn't Tridactyl work/why does it break the websites I'm trying to use?
Please visit our troubleshooting guide.
How can I change the search engine?
set searchengine duckduckgo
How can I add a search engine?
set searchurls.esa http://www.esa.int/esasearch?q=
You can also add
%sto specify exactly where the search query should go, which is useful for more inventive uses, such as
set searchurls.phrasebook https://translate.google.co.uk/#en/%s/my%20hovercraft%20is%20full%20of%20eels
open phrasebook [fr|de|la|es|hi|it...]will work as expected.
Can I import/export settings, and does Tridactyl use an external configuration file just like Vimperator?
Yes, if you have
~/.tridactylrcwill be read at startup via an
source. There is an example file available on our repository.
If you can't use the native messenger for some reason, there is a workaround: if you do
set storageloc local, a JSON file will appear at
<your firefox profile>\browser-extension-data\email@example.com\storage.js. You can find your profile folder by going to
about:support. You can edit this file to your heart's content.
I hate the light, can I get a dark theme/dark mode?
colors dark. Thanks to @fugerf.
How can I pretend that I'm not a 1337 h4x0r?
We cater for you, too!
colors shydactyl. Thanks to @atrnh.
How can I pretend that I'm a 1337 h4x0r?
We cater for you, too!
colors greenmat. Thanks to @caputchinefrobles.
How can I bind keys using the control/alt key modifiers (eg:
:bind <C-f> scrollpage 1. Special keys can be bound too:
:bind <F3> colors darkand with modifiers:
:bind <S-F3> colors defaultand with multiple modifiers:
:bind <SA-F3> composite set hintchars 1234567890 | set hintfiltermode vimperator-reflow
CR == Enter).
If you want to bind <C-^> you'll find that you'll probably need to press Control+Shift+6 to trigger it. The default bind is which does not require you to press shift.
How can I tab complete from bookmarks?
bmarks. Bookmarks are not currently supported on
*open: see issue #214.
When I type 'f', can I type link names (like Vimperator) in order to narrow down the number of highlighted links?
You can, thanks to @saulrh. First
set hintfiltermode vimperatorand then
set hintchars 1234567890.
How to remap keybindings in both normal mode and ex mode?
You cannot. We only support normal mode bindings for now, with
bind [key] [excmd]
Where can I find a changelog for the different versions (to see what is new in the latest version)?
Why can't I use my bookmark keywords?
Mozilla doesn't give us access to them. See issue #73.
Why doesn't Tridactyl work on websites with frames?
It should work on some frames now. See #122.
Can I change proxy via commands?
Not yet, but this feature will eventually be implemented.
How do I disable Tridactyl on certain sites?
In the beta you can use
blacklistadd, like this:
How can I list the current bindings?
viewconfig nmapsworks OK, but Tridactyl commands won't work on the shown page for "security reasons". We'll eventually provide a better way. See #98.
Why doesn't Tridactyl work on some pages?
One possible reason is that the site has a strict content security policy. You can try to use
set csp clobberto fix this, but know that it could worsen the security of sensitive pages.
How can I know which mode I'm in/have a status line?
jand see if you scroll down :) There's no status line yet: see #210, but we do have a "mode indicator" in the bottom right. It even goes purple when you're in a private window :).
Does anyone actually use Tridactyl?
In addition to the developers, some other people do. Mozilla keeps tabs on stable users here. The maintainers guess the number of unstable users from unique IPs downloading the betas each week when they feel like it. Last time they checked there were 1700 of them.
How do I prevent websites from stealing focus?
There are two ways to do that, the first one is
set allowautofocus false(if you do this you'll probably also want to set
browser.autofocusto false in
about:config). This will prevent the page's
autocmd TabEnter .* unfocusin the beta, JS text editors should still work but pages won't steal focus when entering their tabs anymore.
Help! A website I use is totally blank when I try to use it with Tridactyl enabled!
set noiframeon [space separated list of URLs to match]. If that doesn't work, please file an issue.
Building and installing
git clone https://github.com/cmcaine/tridactyl.git cd tridactyl npm install npm run build
Each time package.json or package-lock.json change after you checkout or pull, you should run
npm install again.
Addon is built in tridactyl/build. Load it as a temporary addon in firefox with
about:debugging or see Development loop. The addon should work in Firefox 52+, but we're only deliberately supporting >=57.
If you want to install a local copy of the add-on into your developer or nightly build of firefox then you can enable installing unsigned add-ons and then build it like so:
# Build tridactyl if you haven't done that yet npm run build # Package for a browser "$(npm bin)/web-ext" build -s build
If you want to build a signed copy (e.g. for the non-developer release), you can do that with
web-ext sign. You'll need some keys for AMO and to edit the application id in
src/manifest.json. There's a helper script in
scripts/sign that's used by our build bot and for manual releases.
Building on Windows
Install Git for Windows
Install NodeJS for Windows
- Current 8.11.1 LTS seems to work fine
Launch the installation steps described above from MinTTY shell
- Also known as "Git Bash"
npm run build & npm run run
You'll need to run
npm run build every time you edit the files, and press "r" in the
npm run run window to make sure that the files are properly reloaded.
A pre-commit hook is added by
npm install that simply runs
npm test. If you know that your commit doesn't break the tests you can commit with
git commit -n to ignore the hooks. If you're making a PR, travis will check your build anyway.
Default keybindings are currently best discovered by reading the default config.
Development notes are in the doc directory, but they're mostly out of date now. Code is quite short and not too badly commented, though.
Principles and objectives
- Keyboard > mouse
- default keybinds should be Vim-like
- actions should be composable and repeatable
- ex mode should expose all the browser functionality anyone might want
- Arguable: most (all?) actions should have an ex mode version (departure from Vim?)
- users can map and define their own actions and commands
- be fast - the whole point of a keyboard interface is to be more efficient, don't compromise that with slow code
- don't crash - we're the new UI and we shouldn't crash
- be maintainable - code should be well documented, reasoned about and tested.
