Zotero Connector add-on in firefox makes firefox lag

smoother · August 11, 2017

Hi,
After I updated firefox to version 55.0.1, I found that Zotero within firefox could not be used any more. It requires Zotero 5 + Zotero Connector. After this, I found that firefox lag very often when opening new tab(s). Firefox most of the time just freeze for 5-10 seconds. Then I disabled all add-ons, then turn on one for each time, to see if which add-ons causing the issue. It seems Zotero Connector causing the problem.
I am not sure if you have the same problem. Maybe other problems rather than Zotero Connector?
Any idea? Thank you guys.

(Zotero for Firefox still works — you just need the latest version for Firefox 55 compatibility.)

We're looking into tab-related performance issues with the new connector, though except for the startup issue I noted there we haven't been able to reproduce anything like what you're reporting. Could you try generating a Debug ID that shows a freeze like this happening?

dstillman, thank you.
For this: (Zotero for Firefox still works — you just need the latest version for Firefox 55 compatibility.)
Seems i cannot find the latest version of Zotero for Firefox in here: https://www.zotero.org/download/

These are not the one like before, which can be installed within Firefox, as an add-on.

adamsmith · August 12, 2017

It's just hard to find (purposefully -- people who start using Zotero now shouldn't be installing the FF add-on), under "Looking for Zotero 4.0"

adamsmith · August 12, 2017

That said, going back now involves a couple of extra steps, so I'd discourage that unless you feel you really must. It's also only going to work until FF57.

adomasven · August 14, 2017

The debug log doesn't show delays of 5-10s and I can't reproduce any significant slowdown with a fresh Firefox 55 profile on Win 10 with Zotero Connector as the only addon. Is Zotero Connector slow even with a fresh Firefox profile?

smoother · August 14, 2017

Hi adomasven,
I also found that sometimes the lag disappeared. The logs were produced when the lag was consistent and repeatable. The new tabs were loading one by one then showed the FF window was non-responsive, need to wait until all tabs loading finished. It was not possible to read other tabs that already loaded. I found that it happens when I clicked on the links of some search results in Google.

dstillman · August 17, 2017

Upgrade to 55.0.2 and see if this still happens. Mozilla fixed a performance regression in Firefox 55 that was triggered by the Zotero Connector. (We need to fix some issues on our end, but they shouldn't cause this sort of slow-down.)
