Under normal circumstances, extensions compatible with Firefox version a.b will also be compatible with version a.b.n for all n. In other words, extensions compatible with 1.0 are also compatible with 1.0.1, 1.0.2, 1.0.3 and so on. Hence Firefox versions 1.0.n shouldn’t break any of your extensions.
Except Firefox 1.0.3 does break some extensions. Extension authors have been notified about the problem, so you should get updated versions of extensions broken in 1.0.3 soon. See below for more info.
Extensions enabled but not working
However, you may find that Fx brings up the dialog saying that it has disabled your extensions for compatibility reasons. You may then find that many (but not necessarily all) of your extensions have indeed stopped working, although they are not actually disabled in the Extension Manager. To resolve this, manually disable and then re-enable all broken extensions in the Extension Manager (by right-clicking each one and choosing "Disable", then right-clicking each one again and choosing "Enable"), then restart Firefox. If you have a lot of extensions installed, you may find it quicker to browse to the folder <Profile Folder>\chrome\chrome.rdf and delete each occurrence of c:disabled="true", being careful not to delete any of the /> symbols. (Reports indicate that this problem applies to Windows 98/ME/XP SP2 having upgraded Firefox over the top of an existing installation rather than uninstalling the original.)
Extensions incompatible with the new version
In Firefox 1.0.3, changes were made for security reasons which break a small number of extensions. Check a broken extension's homepage to see whether its author is aware of these changes. Currently, Dictionary Search is one of those known to be problematic. See also this thread.
