Thanks you all, I know how to deal with the problem with Javascript or overlay, but that's not I wanted, overlay doesn't support in Newest extensions, and javascript means I have to carefully writing down code for different platform and would be redundant. In deed, I ask this question because the whole mozilla source tree still need to preprocess XUL/html files for different OS/Target, and that's stopping us to wipe out the preprocess building system for those files. If we have simple runtime directive to direct which part of XUL files should be exclude out , Like IE(<!- if IE ) does, that's would be a good way to move the current if def instruction out. But seems there is no way to do that. > > > ~ Gijs > > _______________________________________________ > dev-platform mailing list > dev-platform@lists.mozilla.org > https://lists.mozilla.org/listinfo/dev-platform > -- 此致 礼 罗勇刚 Yours sincerely, Yonggang Luo _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
