Some ~10 years ago I used to use a Firefox extension called Vimperator [0]. I then switched to a fork of Vimperator named Pentadactyl [1], because the latter was more complete and stable at the time. And even later I used the Vimium extension on Google Chrome.
But even though I enjoyed these types of extensions, Vim key bindings in the browser powered by these add-ons has always been fragile and prone to stop working all together at times and that eventually caused me to stop using any of them even though I remain a user of Vim and of IDEs with Vim-emulation.
Perhaps these are stable enough today, perhaps not. If I were inclined to go back to having Vim keybindings also in my browser then I would probably want to check out Vieb, as the idea of having it properly integrated into the browser does seem a good idea to me and with Vieb we'd still be getting the Blink engine that Chrome etc is using.
But these days I like to use Brave as my main browser on my MacBook Pro M1, because of the privacy enhancing features that Brave has built into it alongside other nice things. On my iPhone I just use Safari. Occasionally I use Safari on my laptop as well. For example, I have Brave configured to turn all pages into dark mode but some sites become unreadable and then my simple solution because this happens rarely enough to not be distracting is that then I open the page in Safari instead.
Also my usage pattern of browsers has changed. I used to sit on the desktop and read a lot of things. These days I most often read stuff on the phone, and I use the browser on the laptop mainly for looking up things quickly and for using web applications like Google Docs and such. So it's like, one of the main reasons that I used to use Vimperator etc, to navigate by keyboard instead of by mouse, is not as relevant any longer. And even on the laptop, scrolling up and down is smoother and simpler using the touchpad and the spacebar than using Vimperator etc.
When I have the MacBook Pro M1 connected to external keyboard, mouse and monitor I might still benefit a little bit from something like Vimperator. But not enough to be worth the bother anymore, because of the things I mentioned.
Recently discovered this and have been enjoying it a lot. There are some edges but overall works quite well. Also, available for Safari : https://github.com/televator-apps/vimari
There was a problem with the find command '/' [0] I had for months, so I switched to Vimium C as someone pointed out in that thread it was fixed on C already and had other features. I now see that issue was finally fixed last month.
Reading the updated thread now, I see it turned political, and I guess maybe that's why I was downvoted for linking to Vimium C.
Not sure about Chromium, but in Firefox Vim plugins only work if a page is loaded in the current tab. It doesn't work while the site is loading(e.g. to switch tabs), it doesn't work if the page failed to load, it doesn't work in an empty tab, ...
A Vim-based browser doesn't have any of those issues because the whole UI is focused on those controls.
Correct, that is exactly what I was referring to. Back in the old days of addons to Firefox it used to be possible there as well.
Vieb looks cool, but I've already learned Vimium and likely won't switch. Same as with screen and tmux. Maybe tmux is better, but why do I have to learn a tool every 15 years, right?
UI of Vieb is gorgeous. So slick, restrained. Love it.
