> Interesting - I did not realize that XPI and ZIP files were the same. The Zip file format was invented by the late Phil Katz of PKWare, and first used in his PKZip product for MS-DOS. He explicitly placed the format in the public domain and released specs for it, so other people could write software to read and write Zip archives. They did, and every archive utility I'm aware of can create and extract them. (I use the free and open source 7Zip product, from http://www.7zip.org.) It's well documented and understood, with lots of freely available code for dealing with it, so Mozilla's decision to use the Zip format for extension install files makes sense. I've done a fair bit of "bumping" to bypass compatibility problems with Firefox versions by opening the XPI file for an extension in 7Zip, extracting the install.rdf file, changing the maxValue field to whatever the current FF version is, stuffing it back into the archive, then installing the local copy. > Dave _____ Dennis -- You received this message because you are subscribed to the Google Groups "Firebug" group.
