bookmark error comes up when trying to save first time
Bookmarks give an error message when trying to save the first time. After first time, then it saves correctly. I get this message. unload: [Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIObserverService.removeObserver]" nsresult: "0x80004005 (NS_ERROR_FAILURE)" location: "JS frame :: chrome://trustchecker/content/trustchecker.js :: anonymous :: line 955" data: no]

That error message is from something called trustchecker or similar. You didn't bother to post your Troubleshooting Information as requested, so that's about as close to ID'ing that as I can guess.
Tools > Addons >> Extensions - look for that there and either check for an update for it or disable.
