This could be a little misleading.  IIUC, we show the prompt once per extension,
right?  So envision the flow:
user clicks extension on example.com
sees prompt "Read and change all your data on the current website"
  * current website is example.com
accepts
navigates to google.com
clicks extension
  * extension has access to google.com, even though the prompt said "current
website"

Maybe we should rephrase this to something like:
"Read and change all your data on the current website when activated" or
similar?  Unfortunately, "activated" sounds kinda weird.  Not sure what the best
string would be.

Would it make sense to say "all information within this tab"? (Assuming that's
accurate and we're generally OK with mentioning "tab" as a technical term in UI)

I think it's not restricted to only this tab. The first time you invoke you get
the permission prompt and then the activeTab is active for the current website.
If you navigate away or use a different tab, activeTab isn't granted for the new
page/tab, but invoking it won't cause any new permission prompts.

I think Devlin's suggestion is pretty good actually, and I'd go with that one:
"Read and change all your data on the current website when invoked"
