Just as soon as you release a stable alternative...
Win10 comes with Edg & IE11, and your own advisories to the assistive tech using public is NOT to use Edg, rather use your own IE11 or a third party browser instead.
I've got Firefox ESR installed, but it's an utter clusterfuck of a UI that makes it difficult if not impossible to get shit done.
I tried to use Google's Chrome, but the installer wasn't accessible, I needed a sighted person to get it installed at all, and then I found out that it hates my screen reader. Forget trying to surf the web, I couldn't even get past the bullshit "You are not connected to the internet" message it kept coughing up into my face. Yeah, the same internet connection I could use in every other program except Chrome.
PaleMoon, Vivaldi, Waterfox, etalia are all useless from an accessibility POV, so those got kicked to the curb just as soon as they proved actively hostile to my reader.
MS Edg aka Chrome doesn't seem to like my computer either. It won't install & refuses to tell me why. My sighted helper says the error message flashes by too fast to read, so there's not a damn thing I can even research to even figure out WTF.
So MS, I'll stop using IE11 once you or anyone else releases a stable, accessible, useful browser that lets me turn off scripts, block ads, & refuse to let sites use any sort of cookie/tracking/telemetry on me. Not via plug ins & extensions unless the toolbars for those bits is itself accessible.
Otherwise I'm stuck on Win7Pro64 using IE11.
Win10 isn't fit for purpose, isn't stable, is defective by design, and there's no point in even turning my Win10 machine on since it can't even find the internet. Via the same bit of cat5 I'm using through which to type this rant.
Accessibility: you refuse to code for it & I hope you all go completely blind so you can experience first hand JUST how fucked up you've made my life.
