I am using FF 3.6.16 with many add-ons. Before switching to FF 4, how can I determine which ones are compatible with FF4? I won't change to FF 4 if too many aren't compatible.

You can check them against this list, though not comprehensive it shows add-ons that are hosted on the Mozilla add-ons site that make up 95% of add-on usage known to Mozilla - https://addons.mozilla.org/en-US/firefox/compatibility/report

Those listed as 4.0.* and 4.2.a1pre should work on Firefox 4.

An alternative is to install the "Is It Compatible?" add-on, (https://addons.mozilla.org/firefox/ad.../is-it-compatible), I have never tried this one but it adds the compatibility of an add-on to the add-ons manager.
