- a ton of dependencies
- randomly hangs
- can't handle suspending
- cursor blinks when not in insert mode
- doesn't work
- Python not C
- Lacked security features
I'm not sure if all of these are true but this list was their complaints and you'd have to ask them for more detail. A lot of them do sound like they're fixable or just personal preference.
4chan has been discussing options since mid-June and probably has around 50 threads revolving around Netrunner project. And the current devs are not the same people that started the initiative, so the project has evolved quite a bit.
Netsurf, is another project that comes up quite a bit: http://www.netsurf-browser.org/
As well as various forks of the major browsers such as palemoon, icecat, unChromium, ungoogled-chromium, waterfox, opera 12.x, vivaldi, and otter.
> a ton of dependencies
Only Qt and a handful of small Python libraries. Granted, Qt is big.
> randomly hangs
> can't handle suspending
Detailed bugreports or it didn't happen - but that's probably due to people using it with an old QtWebKit version. The latest release warns about that, and v1.0 (coming later this year) will drop support for it entirely.
> cursor blinks when not in insert mode
True - there's an issue open about it, but nobody found a way to make it not blink without other side-effects so far.
> doesn't work
> Python not C
> Lacked security features
That's mostly referring to missing NoScript/uMatrix-like features, which will come with per-domain settings later this year.
