[email protected] : Is it possible to duplicate a tab without reloading it, like actually make a copy of it? (self.firefox)

When I duplicate a tab, a new tab is created with the same URL and I have to wait for it to download again. Why wouldn't Firefox just duplicate all the data of the tab into a new tab?

~~It’s technically possible. Firefox would need to copy the memory used for the current tab into a new set of data structures. This would be less than trivial, as getting it wrong would likely corrupt memory and cause a crash.~~

~~My best guess, being a developer for almost 20 years, is that it’d be safer for the developer to write code that opens a new tab, reloads the URL, and applies minimal state to the new tab.~~

Eh, never mind. After more thought, I wonder if it has more to do with the webpage’s caching policy and web standards than anything with Firefox’s capabilities.
