Frequently asked questions
Can I install Zotero Connector and WPS PDF - Read, Edit, Fill, Convert, and AI Chat PDF with Ease at the same time?
Yes, Chrome runs them independently. Keep both only if they do different jobs; if they overlap, pick one, because each active extension adds memory use, page scripts and another set of permissions.

From each extension's public Chrome Web Store listing. They can lag the live store slightly, and a dash means the figures have not been synced yet.
