Vimium 'O' does not work.
@kulehandluke @evelant @Fortrikka
Alright well I got the party started on this. The first issue is fixed. Navigating with J and K, viewing highlights with F, and a few other functions now work. It was an issue with WebKit's JSON.parse() not working the same as Chrome or Firefox's implementation.
There are some things still not working such as Vimium not getting focus on page load, which means it can't begin typing into the vomnibar or the / search command. Also the / search command is still not working. Something to do with the retrieval of HTML elements by the looks of it in the console.
You can check out the release and repository here → https://github.com/tyirvine/vimium/releases/tag/vimium-2.0.6
If you guys work with JavaScript at all please consider contributing fixes. Vlad seems pretty busy and fixing this is something we could totally manage. 
I have a pull request opened up with Vimium so any changes can be added to that and hopefully we can get them merged. If our fixes dramatically mess with Vimium then they probably won't get merged, so keep them as minimal as possible.
After some exploration, I finally found that the Vimmatic extension on Firefox can perfectly replace Viumium on Orion.
Vimmatic worked for some shortcuts but not others. 'f" "j" and "k" work, but "?" does not, nor do "H" and "L"
So far the most compatible vim extension I've found for Orion is Surfingkeys (from the Chrome webstore). So far everything except moving back and forward in history seem to work, but Orion alreay has keyboard shortcuts for that.
As of right now Vimium Chrome does not work at all
Working in vimium (tyirvine's version) & surfingkeys (chrome version):
- Hints ('f' in vimium & surfingkeys)
This is a pretty good start. This feature is one of the most important and it's working - Navigation between tabs (Basically like cmd+shift+]/[)
Also important and working. - Omnibar (in both)
Although it can't retrieve tabs icons - Retriving the url of the current tab + editing it
- Vim editor in surfingkeys (This feaure is exclusive to surfingkeys)
Maybe I didn't expect this to work
- Closing a tab
- Duplicating a tab
Bugs:
History navigation
History backward/forward (Basically like cmd+]/[)
If you can fix something go for this one and point 2Reopening the most recent closed tab
Also related to history navigation like point 1
Keep in mind that vimium and surfingkeys have problems with point 1&2 but it is capable of showing history in the omnibar
Page manipulation
- Scrolling (using J/K or D/U/E) is a bit laggy (especially in surfingkeys, may not be a bug)
- Hints doesn't work sometimes (exclusive to vimium)
Occurs if you go backward in history and try to use hints (you will have to reload the page)
Others
- Retriving tabs icons
This is important in cases like tab switching (instead of reading the text you just look at the icon of the tab)
I wish to contribute but I don't program (at least not currently), for those who want a good experience surfingkeys works better in orion than the others.
The most important bugs are 1 & 2 (which are related to history) + 3 (which may be the easiest to fix)
Latest update should have fixed lots of bugs related to Vimium, according to changelogs.
I am currently using the extension and collecting feedback, which I will post shortly. There are plenty of features not working properly yet.
Updating this comment soon with a full report

shebg626 "So far everything except moving back and forward in history seem to work, but Orion alreay has keyboard shortcuts for that."
This is my experience as well - although occasionally I've had Vimium stop working midway through a browsing session (e.g. 'f' does nothing) until the tab is reloaded.
Vimium's (capital) H and L not supporting back/foward in history (like cmd-[ and ]) is the main annoyance for me now. It feels like this should be one of the easier bugs to fix.
For what it's worth, Orion works incredibly well for me now (on desktop and iOS), so I'm sticking with it, unlike a couple of past attempts where I gave up and went back to Safari / Firefox.

I don't see anybody mentioning this, though shift+T doesn't seem to work properly for me. Upon pressing the key for the first time on any new page, the omnibar overlay shows up, but doesn't have focus for some reason. I have to click on it for it to get focus, or click anywhere else on the page to dismiss it (since Esc doesn't work either without it being focused). After this, further attempts at shift+T on the same page always works properly.
It seems to be the same for similar functionalities that use this overlay, e.g. shift+O.
Edit: I also tried tyirvine's version though it seems to have the same issue.
xji You're right, there are many more bugs other than shift+T

Hey there, just wanted to recommend the extension called Vimkey: https://chromewebstore.google.com/detail/vimkey/eeeandejdamjifbgmmmmonggidbccnnj
Even though it's been a while (3 years https://github.com/Haojen/vimkey) since the source code hasn't been updated it works just fine when installed as a chrome extension!
eti thank you I will try it
Sorry to necro this thread (though it's only been a few days). The VimKey extension does NOT work as a replacement to Vimium. There are a number of keyboard combos for which Orion seems to take precedence, including X (capital — open closed tab), J/K (capital — move between tabs), etc.
I realize this is a niche plugin, and so it's hard to make it work. That being said, I have an alternate solution, which I outlined here: https://orionfeedback.org/d/10169-allow-full-customization-of-keyboard-shortcuts
