Tampermonkey: [Firefox 57+] All Scripts and Settings Disappear Every Time I Quit Firefox

[pootz10]

I import my scripts from greasemonkey to tampermonkey.
I just read this topic
https://github.com/Tampermonkey/tampermonkey/issues/458
trying to find a solution, but it didn't solve it.

Today I reset firefox to it's default settings trying to see if that would solve the problem but it didn't.
After quit Firefox, the next time I open everything is gone inside tampermonkey. Fortunately all scripts and settings can be imported very quick but this issue.

Do you have have some special settings like

privacy.resistFingerprinting
dom.storage.enabled or
Accept cookies from websites

modified?

[pootz10]

They were on it's default before the reset and should be now, I'm going to check it again.
I'm sorry I had to edit the topic because I hit enter by mistake and the topic was created before my full post be ready.

EDIT
They are all on it's default settings.

Can you please create a new Firefox profile and check? If that's not working, then can you please check Tampermonkey's background console? https://developer.mozilla.org/en-US/Add-ons/WebExtensions/Debugging#Debugging_background_scripts

[pootz10]

By resetting firefox defaults it created a new profile and I don't have another. Do I still need to create another?
I'm not certain if that's the screenshot you want to see, I enabled the debug mode on about:debugging
and reopened the firefox, clicked debug button on tampermonkey and take the screenshot.

I also made the import of the zip file and see the debug mode importing without error only warn about xmlhttprequest

Same problem here :(

Hmm, I have no idea why Firefox forgets the data of browser.storage.local. 😧

However, as a workaround you can switch Tampermonkey to use localStorage only. Please note, that this storage (even though it is an extension storage) is cleared or not available if:

• all recent browser data is cleared,
• cookies are not remembered
• dom.storage.enabled is off
• Accept cookies from websites is off
• privacy.resistFingerprinting is true
  🙄

In order to switch to localStorage please execute this command at the console tab of the developer tools (your screenshot):

localStorage.setItem('#storage', 'localStorage')

and re-start Firefox. Does this make any difference? You can remove this setting at the Storage tab > "Local Storage".

Thanks @derjanb !
I executed that command and now the problem is fixed!

I get undefined

At Local Storage Tab I didn't understood how to remove

I'm starting to think if that issue is not a firefox 57 fault, because I installed violentmonkey extension, imported the scripts and after quit and open installed scripts tab was empty there too.

@pootz10 getting undefined is normal.. restart Firefox, your scripts will be gone, but import them again and restart Firefox you will see that they will be saved :)

[pootz10]

You're right AmineHadef that solved the problem, thank you. Thank you derjanb.

I don't really get what you're doing to fix the problem, and I have the problem, too. Could someone please put instructions for fixing this issue into a tidy, easy to follow, series of steps?

Hi, here is how:

• Go to about:debugging#addons
• Enable add-on debugging
• Scroll down to Tampermonkey and click debug and confirm the message with Ok
• Type this: localStorage.setItem('#storage', 'localStorage')
  in the console and press Enter

That's it, restart Firefox and import your scripts again.. they will not disappear after.
