Why ShowModalDialog function still exists and works in 53 version?
Hello, our software is based on ShowModalDialog function and we are curious if this function is officialy available in version 53? I realised that the function exists and works very well when e10s mode is disabled, and I have to be sure if we can rely on this?

yeah, you've found that out :-D as it's an unsupported feature, any other change (beside requiring e10s) might be breaking it as well - so no guarantees for the future...

hi, this is deprecated in chrome and firefox - you shouldn't rely on it in any circumstance. e10s might become a mandatory configuration one day... https://www.fxsitecompat.com/en-CA/docs/2016/window-showmodaldialog-has-been-removed/
So, as I understand, the moment when e10s will be mandatory is approaching and ShowModalDialog will be completely banned, but exactly in 53 version is still available?
