A good replacement for a now-defunct extension, as many have pointed out; more specifically it seems to have much more robust options, aside from the lack of greylist vs whitelist. However, it seems to have an issue with Google sites in particular where it keeps randomly signing me out. I have added a number of other google subdomains to the whitelist, yet nothing seems to help. Other sites I use work fine however.

Edit: Meanwhile I've identified a problem.
My goal is to preserve data from open tabs across browser sessions. To accomplish this, I need to disable the "Clear Sites from last session on startup" setting.

However, this can lead to a situation where data from closed tabs is sometimes never deleted—especially with significant clearing delays and forced browser termination, both of which occur in my usage.

Therefore, it would be helpful to add a sub-option to "Clear Sites from last session on startup," such as "...but never clear sites in open tabs."


My first review:
Many thanks for this nice work. "Auto-Clear Site Data" is a worthy successor to CAD. Works perfectly for me.

To everyone complaining about missing source code: That's incorrect. Firefox add-ons are always open source by design—to read the complete code, simply download the add-on and unzip it.

Anyway, I must emphatically reject the author's flawed reasoning: The notion that concealing source code improves security is not only wrong—it demonstrates a fundamental misunderstanding of how security actually works. Obscuring code does not protect users; it only prevents security researchers and the community from discovering and fixing vulnerabilities. This is basic industry knowledge. Any developer with genuine expertise knows that open-source scrutiny increases security, while secrecy creates blind spots. The author's position, however well-intentioned, is both technically indefensible and counterproductive.

and you still haven't open source this?

please add option pause for for all site

Found this after looking for an add-on to selectively clear local storage and I am so glad I found this. Works very well - it has replaced Cookie AutoDelete (CAD) on my phone and I am considering using it alongside CAD on my computer.

An observation after using it with Iceraven (Android):
- it appears it is affected by Total Cookie Protection (network.cookie.cookieBehavior = 5) or the 'Isolate cross-site cookies' option in Enhanced Tracking Protection, so partitioned folders are not cleared... this is a little difficult to explain. But by disabling the isolation (choosing 'Cross-site and social media trackers' or network.cookie.cookieBehavior = 4) this can be avoided. CAD also required this to work properly.

I can see that it is clearing the ls and idb folders for sites as I have set it, leaving just the .metadata-v2 file in /storage/default//. It would be great if it could delete the whole folder, but this is probably beyond the capability of WebExtensions.

An excellent extension that does what it says. Well done!

"All Rights Reserved"?!? Proprietary, closed-source extension for very sensitive topic from a privacy point of view, such as cookies/storage for EVERY website?!

Sorry, but no source code provided plus closed license of this extension is unacceptable.

I were installed your extension on Android. It's worked, but i actually looking for "Auto-Clear" for specfic sites.

- It mean it's reverse filter option of `Exemption Lists`

- Can i request this feature ?. Or if you have git url of sourcecode. I can help with a PR.

Works as advertised and a worthy successor to CookieAutoDelete. Keep up the great work!
