Preview in browsers opens multiple tabs (but Safari refresh the page)

[jonathan (Jonathan Deutsch)]

I believe you probably found this thread, and unfortunately my answer still stands:

Preview in Chrome opens multiple tabs, instead Safari simply refresh the page

We looked into a solution a couple of years ago for this problem but were hit by significant roadblocks due to the macOS sandboxing security technology. My recollection is that there are some Chrome extensions that you can setup that will allow reusing a tab if the same URL is attempted to be opened. I don’t know which one is best (I personally just use Safari that does not have this behavior!) so if you find one please report back with what you used .

I just tried the "Duplicate Tab Helper" extension in Chrome to see if it had improved, but I couldn't even get that to work.

There's probably some way to properly jerry rig this with Hype's Export Scripts and AppleScript; I just remember that the solution we tried wouldn't be allowed on the Mac App Store (and I think also required lots of fragile permission prompts).
