This site no longer runs on my browser, Safari 8.0.8, in a way that allows me navigate the site with usual navigation buttons found on the top of each page of the site. As of today, some of the buttons no longer appear and the ones that do don't execute properly when I click on them. They were all present and worked fine yesterday.
My browser, although old, is only having problems with SE sites. It does not misbehave on any of the other sites I visit. For instance, in constrast to SE sites, I have no problems at all when I sign into the Wolfram Community site. The problems stated a couple of months ago and have steadily gotten worse. They have reached the point where I feel I can no longer meaningfully participate. For example, to post this question I had to enter the URL
into Sarfari's search field. I not could use any of the usual navigation controls to reach Meta's Ask Question page.
I am working on up-grading my computer's OS from OS X 10.10.5 to OS X 10.13.3. This is a time consuming effort, but it will certainly give me the latest version of Apple's Safari browser and, perhaps, may fix my problems. I certainly hope so. If it does, I will be back. Otherwise, this is goodbye.
Can anybody tell me what versions of Safari are supported on this site? Alternatively, can anybody tell me where to go in the SE environment to get this information?
I ask this in the hope that there is an interim version of Safari that will run on mu current OS X 10.10.5 system and will enable me to remain in touch with Mathematics.SE community until I finally get OS X 10.13.3 up and running.
