One thing I want to report with the Zotero Firefox Extension is that it seems to cause Orion to become laggy after days.
Previously I after found that problem, this post (https://orionfeedback.org/d/3088-after-1-2-days-orion-becomes-very-sluggish) suggests that it may be the extensions issue, so I disabled all extensions and Orion didn't get laggy. Then, I uninstalled the Zotero Firefox version and installed Chrome version (for I thought it might have higher compatibility); Orion then worked smoothly for days until I found that the Chrome version does not work. Then after I switched back to Firefox version, Orion starts to be laggy soon. The behavior is that opening new window through cmd+n takes 1s every time, and right click -> open in new tab sometimes takes 1s or even 5s to respond.
So, to summarize, all extension disabled -> good, only Zotero Chrome extension -> no lag but no zotero, only Zotero Firefox extension -> lag. I would really appreciate it if that could be resolved.
