I just installed the Firefox add-on 'Self-Destructing Cookies' to my Win 7 laptop. It seems to be working okay, but the icon doesn't show up in my addon's toolbar (even though that item is checked in the Options section). I even checked the 'Customize' section to see if it was there so that I could drag it into position, but not there either. I even uninstalled it and reinstalled the add-on, but that didn't help. Any suggestions?
You could install the developer version and see if that fixes your problem. Edit: Just saw that the dev version is currently older. So forget about that, just check in which mode your Firefox version is, if it's in safe-mode/incognito then this is a known issue.
New version is out, changelog: From the FAQ: Q: Will this add-on ever be multi-process (e10s) compatible? A: Add-ons can't monitor sites' LocalStorage usage in e10s mode. This functionality will probably never be restored for legacy add-ons such as SDC. This means that the answer is "very likely never". You can still force-enable e10s and SDC should clean your cookies just fine, but it can only clean your LocalStorage when the browser starts.
I'm not sure if this is correct. Its AMO site says: And the Cookies Exterminator add-on which says that it is "inspired by Self-Destructing Cookies" explicitly mentions: But I don't use flash anymore so I'm not affected.
Me too. More and more websites are switching over to HTML5, so i don't "have to" use Flash. And therefore no cleaning of these cookies is needed. There will be no Webextension-version of this extension:
FWIW, there is a webextension with similar capabilities called Cookie AutoDelete. Unfortunately, it's not yet able to clear LocalStorage as the necessary API in Firefox must be extended. Let's hope that this will happen before long.
