Firefox 1.5 Beta 1 which has a work name Deer Park is released! You can download it here, test it and help to developers to make Firefox 1.5 perfect! Changelog is here.
Persinally, I’ve already downloaded Firefox 1.5 Beta 1 and I’m ready to try to use it :).
Updated: Note that after upgrate current version of Firefox to 1.5b1 many useful extensions (Web Developer, for example) will be disabled because there are not enough extesions for that version!
Extensions can be easily made available again by changing maxVersion for Firefox in extension’s install.rdf. Most of them still work without any errors.
BTW, it’s not good to use “Deer Park” name for the beta. This name was used for alpha releases but beta ones are branded only as “Firefox” again.
Many thanks for your receipt how to fix a problem with extensions. It’s really interesting thing! I did’t explore Firefox yet (not enough time).
About name “Deer Park”: probably developers just forgot to change it before release of beta version.
