With the addon installed you can. The global search box does not disappear but can be used for local filtering.
What I'm not sure about is the indexing which is what you don't want I guess? Doing active search over all accounts etc. was always possible with Ctrl-Shift-F if I'm right.
So I don't know if disabling the GLODA in the Thunderbird preferences while keeping it active for local filtering with the add-on disables indexing or not. How can I see that? Is there an index file/directory to check?
