i love firefox addons for certain quick tasks. they get things done so much faster and there are some really nice ones that i use regularly.
one of them was Exif Viewer, until it stopped working with version 3.6.* of firefox.
since there was no update since July 2009 i didn’t expect a quick fix. so i did it myself.
here is what you do to make the addon work again (i already had it installed when i upgraded firefox to 3.6).
go to (the SOME_HEX_ID part is usually different for everone)
and edit the file
install.rdf in that directory.
em:maxVersion="3.5.*" /> <!-- Firefox -->
em:maxVersion="3.9.*" /> <!-- Firefox -->
or a version number that suits you. after a firefox restart the exif viewer addon should work again.
i give no guarantee this will work on any version of firefox. after all there is a reason they put a version number in there
