Preferences got deleted when addon updated

• I am running the latest version
• I checked the documentation and found no answer
• I checked to make sure that this issue has not already been filed

Expected Behavior

Preferences persist across add-on updates. Is it possible to store user preferences/data in the Firefox profile, aka so the addon userdata gets stored/synced with Firefox Sync?

Current Behavior

When the add-on updated to v0.22.43, I discovered that all my whitelists had been deleted, and I'm pretty sure that all my preferences across the entire add-on (i.e. for default settings) were also reset. I don't know for certain that it was the add-on updating that caused this, but it's the only event that I can think of that coincides with my data/preferences being deleted. I'm curious if any other users have had this issue.

Hi @e-t-l,

I tried updating from v0.22.42 to v0.22.43 and couldn't replicate this issue. Was Chameleon the only addon that was affected?

[e-t-l]

Thank you for trying to replicate it. Yes, Chameleon was the only addon affected. I've been wracking my brain for anything else that might have caused it to lose its userdata.

Mine's been deleted about 5 times now and it's not with updates. The only consistency I have identified is that I add a site with some preferences, and then they are wiped.
It only happens to Chameleon, no other addons.

Thanks for reporting this. I'll look into this angle further. Seems like a bug with how settings are being saved then.

@e-t-l Just noticed you also requested support for Firefox sync. If I recall correctly, this is straightforward to implement. Should have that done soon barring any surprises.

I've just encountered this same problem today for the first time, on LibreWolf not Firefox, the extension works fine on the latter. Restarting the browser cured the issue, which was fine as I only had a few tabs open, but it wouldn't be so convenient at other tomes when I have more tabs and windows open.
