I was not able to comment in this locked discussion…
so I am once again raising this topic. A very big difference when browsing in private mode using Safari (I'm using version 12.1), as opposed to FireFox or Chrome is, every new Safari tab requires an additional login if you're visiting a secure site. Login creds do not propagate from tab to tab. This was noted in the prev. locked discussion as a key differentiator betwixt Safari and Google Chrome, and sure enough FireFox is also able to open new tabs and preserve user creds. I am a big fan of opening links in new tabs for many reasons. Logging into every new tab is a major pain in the butt.
Here's just one of many examples why I regularly open most links in new tabs: Some forums, once an advanced search window is entered, do not allow the use of the "back" arrow to get out of "Search" to the previous page. You are STUCK in "search". Forever. I get bored in there, ha. So I open any old link in the forum as a throwaway and access advanced search from there. After I get my search results I can close it and click back to the tab where I'm reading. I do this for online banking, forums, Gmail… I do it all the time.
I started moving away from FireFox 'for a second' because it's constantly hounding me to UPDATE UPDATE UPDATE!
DANGER WILL ROBINSON, DANGER!! UPDATE!!! (please flail your hooks for that last reference.)
Safari doesn't do that, at least not in any annoying way that I notice. But I'm back to the Foxy now, because of this fairly crippling absence of 'tabular communication'.
