What I mean is, the Firefox version that installs as an add-on I think was version 26.6 or something?
If I have that one as an add-on for Firefox all is well. Apparently the new version 2.8 works for both Firefox and IE, so if I download it, it overrides the Firefox version 26.6. I'd like to use that old version for Firefox and I guess the old version for IE so it won't override the FF version.
This all has to do with a program called Sandboxie - the IE version of Siteadvisor won't work with Sandboxie, but the FF version will.
