Description of problem: When Firefox is started automatically as part of a KDE 4 login (because it was open when the user shut the machine down) it is unable to find any plugins. Version-Release number of selected component (if applicable): firefox-3.0.4-1.fc10.i386 How reproducible: Repeatable every time Steps to Reproduce: 1.Open Firefox on an FC10 KDE install. 2.Open several tabs on websites then shut the machine down. 3.Restart the machine then log back in. 4.Type about:plugins into the address bar of the FF instance that automatically loads. 5.Visit a (for example) Flash enabled site to verify Flash isn't present. 6.Close FF (hitting the option to save and quit. 7.Open FF again. 8.Type about:plugins into the address bar Actual results: The first about:plugins (step 4) says that there are no plugins installed and the Flash site loaded in step 5 will show the "additional plugins required" message. The second about:plugins shows the correct plugin load and all the sites load and display correctly. Expected results: Plugins should be found at step 4. Additional info: I also had this problem on FC9.
Pretty much a dup of F-9's bug #437596 (I'll leave it to ff's maintainers to keep a separate F-10 bug open or mark the dup). See also upstream bugs: http://bugs.kde.org/show_bug.cgi?id=167373 http://bugzilla.mozilla.org/show_bug.cgi?id=262258 fact is, currently, ff's and kde4's notions of session management is incompatible. Best/only recommendation for now is to avoid the keeping ff open on logout/shutdown.
