Firefox on a Windows 10 machine? Seems like something fairly standard.
I resolve this by disabling spell/grammar check on the browser. And everything else. While the occasional error slips through, I just hate all the highlighting that comes with someone else's opinion of how things should be written. Not to mention the outright spelling errors as noted earlier in this thread.
Technology is great, but there is such a thing as "being too helpful". Glad they "let" us disable these "features". I sure wish Microsoft would allow us to disable Windows Update. Maybe I could upgrade from Win7.
A constant peeve of mine is people not upgrading their virus-carrier operating systems to supported, fixed releases. It does not matter if you tell yourself that it's not going to get connected, sooner or later you will, because today, not networking a computer renders it useless.
It is a sad state of affairs that special hardware and software gets written by people not employing more timeless techniques. The lure of the then-greatest soon-to-be-deadend technology (Remember Silverlight? Flash? Any of the Java releases with special features?) is constant. Ten years from now, we'll be swearing over .NET code that cant be gotten to run. And this means that old, dangerous computer installations out of maintenance will remain alive and connected to the Internet.
In my case, I'm mourning a very nice sound card, that had the misfortune of being
- A FireWire connected device
- A M-Audio piece of hardware, and as such abandoned by them way too early.
It is useless to me, and to most other people, because it's only supported with drivers in OS releases that ought not to run anymore.
