Comment 24 for bug 428306

I suspect the cause is that awhile back the mars were made to always remove the search engines in the install dir and install the ones included in the update. I'm not sure what the requirement is that drove that decision but I personally don't think we should be removing / adding the search engines everytime.

gavin, bsmedberg: can you shed some light on why this was done and if this behavior can be removed? If not, then this will likely need to be fixed in the search service.
