Looks like IndexedDB.open fails if the URL is > 255 characters.

I think this only happens with the file:// protocol

Is this related to bug 1166060?

Comment 3

Definitely sounds similar, but I can't tell if fixing bug 1166060 would fix this as well.

this as well.

Yeah, that bug is now fixed and helped a lot, but I think we can still hit the MAX_PATH, if the HTML file is stored very deeply in the directory structure:
<profile>/storage/default/file++++Users+foo+subdir1+subdir2+subdir3+subdir4+subdir5+(more subdirs)+index.html

We need to replace the long origin directory name (taken from the File URL spec) with a unique (fixed size) name and store the mapping in a database.
