Chrome plugin absolutely draining memory

speasley · April 14, 2024

With the Zotero Connector running, Chrome is nearly unusable. If there is not a memory leak in the plugin, it is so memory intensive that I cannot run it. Is this a bug? Is anyone else experiencing this?

I'm running Chrome v116.0.5845.96

We haven't gotten any other reports of this, no.

If you go to Window → Task Manager in Chrome, what does it say for Zotero Connector?

What happens after restarting your browser? Disabling all other browser extensions?

I have the same issue on Mac.

In chrome 135.0.7049.85 (Official Build) (x86_64):

@alehandro112, @alehandro112: See my questions about restarting and other extensions.

Noticed a similar issue, right now Zotero Connector occupies almost 2GB of RAM. The number seems to increase by a few megabytes sometimes on opening a new tab (the home page is standard Chrome "new tab"), but it never seems to go down until a browser is restarted.

Other browser extensions seem to have no effect on this.

Same issue on Edge 136 on macOS (Apple Silicon), ~5GB usage.

We would be happy to look into this, but someone will have to describe what it takes for this to happen? Does it just passively increase in memory? Does it matter which websites you use, or how many tabs you have open?
