The Tabby Reopen Current Tab on Reload plugin enables the currently active tab in a tabby responsive tabs tabgroup to remain the active tab after the page has been reloaded. This works by updating the target parameter in the url query string shown in the browser address bar. Due to this it is only possible to target a specific tab within a single set of tabs on a page.
The cost of this add-on including updates and support for one year on a single site is £24.
The Developer option including updates and support for unlimited sites is £89.
