Thanks for the feedback. That would be useful, but it is a different cleanup mode from what the extension currently supports.

Firefox’s browsingData API works with “clear data since this time”, which fits options like last hour, last 24 hours, or all time. “Delete data older than X days” is not available for every data type, especially cache and site storage.

I’ll keep it in mind as a possible future option for the data types where Firefox supports it, such as history.

Thanks for reporting this. Android support had a real issue in version 4.9, and I fixed it in version 4.10.

Version 4.10 has been submitted to Mozilla and is waiting for review/publication. Once it is available, please update and try again.

One note: this extension clears Firefox browsing data through the WebExtension API. It does not clear the Android system-level app cache shown in Android Settings.

Thanks for the report. You were right that Android was not working correctly in version 4.9. I investigated it and fixed the issue in version 4.10.

Version 4.10 has been submitted to Mozilla and is waiting for review/publication.

One important detail: Clear Cache clears Firefox browsing data through Firefox’s WebExtension API. It does not clear the Android system-level app cache shown in the phone’s App Settings screen, so that number may not change even when Firefox’s web cache is cleared.

Once 4.10 is available, please update and try again.

Thanks for the report.

If you stay logged in after clearing, the most likely reason is that “Cookies” was not selected in the extension options, or “Site data only” was enabled with a data type that Firefox cannot clear per site.

Cache clearing alone will not log you out. To remove login sessions, cookies must be selected. Some sites may also keep sessions through storage, so selecting Local Storage / IndexedDB can be useful too.

I improved the options and error handling in recent versions to make this clearer. Please check the selected data types in the extension options and try again.

Sorry about that
That really sucks. It was a bug in 4.4: “Current tab only” could wipe more than it should. I’ve already fixed it and sent the update to Mozilla, just waiting for approval. Once it’s out, it’ll behave correctly.
Please update when it’s available. If it still happens, tell me the version and I’ll dig in.

Sorry about the surprise

I get why you’re upset. Just to clarify: the default doesn’t wipe cookies, it only clears cache. Losing logins would happen only if “Cookies” was enabled in options. The current default is cache only + current tab, but the time period is “all time.” You can switch it to 15 minutes in Options.
I also have long‑time users who prefer a full clean by default, which is why I kept “all time” as the default. Still, I’m open to adjusting it if most people want 15 minutes.

Sorry for the late reply. This behavior was a bug in 4.4: “Current Tab Only” could end up clearing data beyond the active site. I’ve fixed it and submitted the update to Mozilla, just waiting for approval. Once it’s out, it’ll behave correctly.
Please update when it’s available. If it still happens, tell me the version and I’ll look into it right away.
