The current version of Firefox ESR is 102.14.0. I have no Idea what you have installed
And both versions came out the same day... it's confusing
I guess it depends on which distro, which repo or which source. The tar.bz2 mentioned by hacktheworld is usually downloaded from mozilla rather than a distro repo, but there are other mirrors.
did you try the method that worked for thunderbird 115 in your other thread: https://www.linux.org/threads/thunderbird-115-supernova-icon.45940/#post-198831
I remembered the thread, but I messed up because I didn't follow the procedure correctly. Now it works!! Thank you very much!!
