This should be fixed for you now. To my surprise, some legitimate versions of Firefox report 'rv:109.0' with a Firefox/<ver> version that is not 109 (along with all of the crawlers that have latched on to 'rv:109.0' as something they put in their User-Agent strings along with random old Firefox versions).

It looks like those versions will continue for some time, at least until Sep 2025 on Win 7-8.1 and macOS 10.12-10.14, given the recent announcement:

    https://www.ghacks.net/2025/02/19/mozilla-extends-firefox-support-for-windows-7-to-september-2025/

and I can confirm that I can now read your site using the native user agent string. (FWIW, I expect to upgrade to FF-128 within the next couple of months.)
