Firefox: Localstorage error when "resistFingerprinting" is turned on

Fixed or Completed
1

(PS: This is an experimental Firefox setting. So I don’t necessarily expect a fix on this, but I thought mentioning it wouldn’t hurt.)

Setting privacy.resistFingerprinting to true in Firefox’s about:config results in this message popping up.

This error did not occur on Feb 7th but does on Feb 8th (German time, worked around 1644260400, didn’t work around 1644296400) so maybe something was changed in the “Export all spaces” version?

Functionality does not seem to be impacted. I have not tested anything while offline, but everything got synced while online (multiple browsers, private tabs. no issues)

Maybe the privacysetting wasn’t it. It is turned off but I am now seeing the same error reappear. Logging out and in again seems to work for a short while but then it reappears. I am sorry I cannot give more information but I don’t know how I can debug this further. I am pretty sure this is a local problem as I didn’t have any issues with my work laptop today. Would appreciate any hints :frowning:

This may be related to Firefox silently fails to save to localStorage , any console errors?

Yikes. I played around trying to recreate the issue and log console errors.

  • the message (in the screenshot above) does not appear anymore
  • the syncing sometimes happens, sometimes doesn’t
  • cards get moved from a space to another. I had seen this one or two days ago but thought I’d have imagined it (~0:54 in the video)
  • there is a lot of output in the console

I have recorded a video and copied the console output to text files. I wouldn’t really know what I should be looking for, so I hope that’s fine?

the vid/logs were v helpful, it’s hard to tell what the exact source of the errors was without being able to repro myself. But I’ve added some potential fixes for the spaces not syncing. Let me know if you see the same issue again
