Folder Named "component_crx_cache"

AllanH

Since I updated to Version 6.2, I've noticed that Vivaldi creates a folder with the name "component_crx_cache" in the User Data folder.
Could someone tell me what that folder is?

Interesting, they seems to be in the same format as Chrome Extensions (hence the crx in name), they can be opened as zip files, in one named

I can see download_file_types.pb so it's probably a way of chrome/ium to update its own files.

Yeah, just cache of downloaded components required for Chromium to function. Can probably be safely deleted, but will just get created again.

$ for f in $(ls *_1*); do unzip -qo $f manifest.json 2>/dev/null; grep '"name":' manifest.json; done

The only one of "slight worry" here is First Party Sets - Google's sneaky attempt at overriding blocking of third-party cookies ...

Vivaldi doesn't use this anyway, but probably should nuke the component completely like they did with FLoC.

Thanks to both of you for the information.
