hello: i recently updated firefox (win64) and found that some critical extensions i use havent been ported to the new version. i had to reinstall 56.0.1. i'm hoping that in the near future the extensions will be updated, but until then i cant go to v57.x. my concern is security of v56.x and potential security patching. * is v56.x going to receive security updates going forward? im not concerned about functionality updates, only security patches. * when will any updating besides a move to v57.x end? thanks, jr
