looks like bug 331581. do you have the needlesearch extension installed?
I don't have needlesearch nor session saver installed
OK, do you see the bug with a clean profile and no extensions?
> When using a clean profile, I get much less errors in JS console only a few : Are any of the extensions installed to the app dir instead of the profile so that the clean profile would still see them?
The bug is confirmed in the last Seamonkey release 1.0.7
To kill adblock, if it's in the app dir, is just delete the directory where it resides, c:\program files\<seamonkey dir>\extensions\<adblock dir> What do you see in error console after that?
(In reply to comment #8) I don't know since which release this issue disappeared, but with the current one, it's gone ;)
thanks for closing, but FIXED is not an appropriate resolution. See https://bugzilla.mozilla.org/page.cgi?id=fields.html#status let's call it INVALID (rather than WORKSFORME) because the main problem, related to tabbrowser extension, was gone with clean profile in comment 4
