Extension crash all time

[dfullts]

When I gave the download button the extension stops responding after a short time, the images are not downloaded and chrome reports that the app crash and will have to reload again.

Based on your report, it seems like your browser is not able to provide enough memory for the extension to generate the ZIP file.

I've written a new memory-efficient ZIP implementation that uses IndexedDB for temporarily storing the chunks. With this new commit, this extension is going to use much less memory for ZIP creation, however, note that still for the final stage, the extension needs to load all the binaries to the memory for a very short time to create a single blob that is passed to the download manager of your browser. Hopefully, this new implementation works!
