How to avoid plugin loss when reinstalling the system or Brave?
The portable version should be free of installation, plugins, and bookmarks without losing data.
The extensions in the Date folder don't seem to work, you must reinstall these plugins.
Unable to protect user data, it seems that this is not a portable version and is no different from the installation version.
If your plugin is decompressed, your browser will delete these decompressed plugins after the system restarts. How can this be avoided?
Can only drag and drop. crx for installation?

Thank you very much

I've had it corrupt etc, but it is in fact portable I've used it on three different systems without losing my data
But I do use a brave sync chain, so when corrupted it just rebuilds.
Any chromium browser doesnt fully install plugins from files, they are usually only temporary and meant for 'testing' and 'development'
Install from the chrome webstore
