We currently have multiple tab tags open on our site:
tabs Tabs are a graphical user interface feature that allows multiple documents to be contained within a single window.
browser-tabs The tag has no usage guidance, can you help us create it?
The last possibly from an earlier cleanup.
I suggest moving the remaining browser based tags to browser-tabs or all to tabbed-interface. (which a browser interface is just one specific instance off. So tab-interface would be more generic than browser-tab, worksheet-tab, beer-on-tab, ...)
