I am the developer behind Open Access Helper, Wayback, TabCount & Spesensatz - all for macOS / iOSI provide all my apps free of charge on the App Store, but if you wanted to buy me a cup of tea, I'd very much appreciate it. It is totally voluntary, of course!
Thank God we finally have an extension to limit opened tabs in Safari! Thank you so much, Claus!
Thanks for the do not allow more tabs feature in Tab Count, now I can finally work more focused without the never ending tab clutter. Vielen danke!
Long searched - now found. Great, thank you very much!
Thanks for writing this extention!
