3.7.0 Much slower than previous versions

[Crul]

Final?-EDIT: The problem was the Firefox Extension DuckDuckGo Privacy Essentials. Disabling it fixes the problem.

EDIT: I found that disabling all my Firefox Add-ons solves (or almsot solves) the problem. So feel free to close the issue. I left it open because there is a difference between the previous version and this one that you may want to take a look.

Describe the bug Starting today (21st June 2023) , CommaFeed performance is much worse than yesterday.. Almost any input (except scrolling, EDIT: I found that the custom context menu [mouse right click] also works fast) takes around 2 or 3 seconds to be processed. This includes: opening / closing articles both with mouse click and keyboard shortcuts, marking them as read It happens even with low number of articles loaded (50).

I asume is related to the latest deployment, but I may be wrong, I haven't debugged it to confirm the cause.

EDIT: I forgot to say that I have more than 2000 feeds (I know it exceeds the current limit, I'm working on a script to unsubscribe from a few hundreds of them).

Environment (please complete the following information):

• CommaFeed version (or "commafeed.com"): 3.7.0
• Browser [e.g. chrome, firefox]: Firefox 114.0.2 (64-bit)
• Device [e.g. desktop, mobile]: Desktop, Windows 10

Thanks!

It seems it only happens in Firefox. I tested in Chrome at it works fast.
