Whoever gives 1, 2 or 3 stars has no idea and is unfair! This add on does exactly what it is supposed to to: 5 stars.

This addon has hidden ADware inside, occasionally opens pop ups

Works for me. Thanks.

There is a better solution for flash cookies long time.

I was a user of Better Privacy as well until WebExt came along.

The following extension Cookie AutoDelete https://addons.mozilla.org/en-GB/firefox/addon/cookie-autodelete/ has the ability to clear local storage now:

From CAD docs
Some things to Note:
- This extension can clear localstorage as of version 2.1.0 and Firefox 58+. Enable it in the settings.

HTH

I'm going to rate this for the effort at making a replacement for BetterPrivacy. To simply rate it a one star because it doesn't have the same functionality (and may not be possible to achieve) seems unfair in my opinion.

The comments thus far remind me of what executives at large companies I consult to have told me over the years: there are about 30 complaints for every complement. Sheesh, imagine working in Customer Service at even the best-run organization.
I for one appreciate the author's effort; further, he has not only explained why he cannot achieve, under the new FF API, what Better Privacy did, but pointed out how to get to a control panel to tailor things.
Kudos to the author, and thanks for the FREE add-in and accompanying info.

I have FireFox v58.0.1 installed on my Mac laptop. It seems to get reported as Opera for some unknown reason. I try to select your add-on to install, but I get the message that I have to install FireFox first--which I am using at the time.

ADware запиханное в видео затрахало! Удалил к чёрту!

As many have given enough reasons, explanations and pointed out, this extension comes (very) short of BetterPrivacy, sooooo : One star + One star, for developer's honestly efforts and replies. However, if wants/needs more stars then ... just make a BetterPrivacy extension AGAIN!, compatible with Firefox57+. I shall uninstall this (nearly useless...) extension and wait for the NEWBetterPrivacy if and when it appears.

I'm sorry, but this is a truly do-nothing extension.

The purpose of having an extension for removing flash cookies (LSOs) is to have the option and ability to remove LSOs DURING the browsing session, NOT to remove them before the next browsing session begins. The way "Clear Flash Cookies" works does nothing for the user on a practical level. Anyone can navigate to the folder containing the flash cookies and remove them manually.

The only reason that Better Privacy is defunct is because of the changes in Firefox, not because there was anything wrong with Better Privacy. It was a very good extension for preventing and removing LSOs from the user's computer, and it allowed the user to set the security level and functions of the extension. It did not interfere with browsing, and it provided real and real-time protection DURING the browsing session, and gave the user control of his or her security and privacy in regard to nefarious LSOs; which is the whole purpose of having a flash cookie removal extension in the first place.

The "Clear Flash Cookies" extension does none of that. Since it does not remove LSOs DURING the browsing session, at the time the cookie is being placed on the computer, then for all practical purposes it is doing nothing. It still allows security-breaching, nefarious LSOs that steal sensitive information to invade the user's computer -- and remain there until Firefox is closed and launched again. Since there is nothing to indicate that it has actually removed any cookies at all, I question whether it actually removes any LSOs at all. I'll have to check and see.

Also, there should be some way to ensure that the LSO containing the global settings (such as access to a webcam, access to the microphone, the amount of data that can be stored on the user's computer, etc.) is protected and not deleted along with other LSOs. Better Privacy made provision for that. Maybe I missed it, but I have seen nothing that indicates that the global settings LSO is protected by "Clear Flash Cookies", or that it is not deleted.

I hope that you will rewrite this extension so that it is user friendly, interactive, and can be modified to users' satisfaction.

In your favor, it seems that the only privacy and security enhancement extensions that work on the new Firefox "Quantum" (57.0.1) are "do nothing" extensions that give the illusion of security, but actually do nothing or maybe even compromise user security. So, you're not alone.

Sorry to be so blunt, but that's the only way I know to be where my privacy and security are concerned.

Internet users CAN take back our privacy and security, but it is going to take ALL of us working TOGETHER toward that end--especially browser and extension developers. In some ways, Mozilla and some of those who write extensions for Firefox have either forgotten that, or they have sold out. Maybe the corporations and the No Such Agency have threatened them if they fail to comply and co-conspire with them to rob the people of their privacy and keep them vulnerable. Whether willingly in cahoots or coerced, complicity is complicity.

An overgenerous two stars for your effort. In an age of digital paranoia, not being able to see what's occurring is pretty short sighted, to say nothing of inconvenient. This is the 21st century version of "THE EMPEROR'S NEW CLOTHES."

Without a functioning whitelist this program may cause more troubles than not having implemented a LSO-eraser a all. Definitely NOT a good replacement for "Better Privacy". I have meanwhile deactivated it because it doesn't give me a choice. Waiting for Better Privacy to come back. PLEASE. Go to work! Once Better Privacy is back, I may donate.

Better Privacy miss me

Locks up FF Quantum for a good 20-30 seconds at launch.

Description compares this to BetterPrivacy.
BetterPrivacy had a pop-up that showed how many cookies it deleted.
I can't tell what this is doing if anything.

There's no way to see what's happening. Following the suggestion to view existing Flash cookies in Adobe's Flash Storage Settings panel is a nonstarter. That requires activating Flash. I'm not going to be doing that.

In response to developer's comment: Exactly. As a rule, I do not enable Flash. But this has on occasion not stopped fishiness going on with LSOs on one of my computers running Firefox, in the past. Now I have no way of knowing for sure.

It's great that a new WebEx compatible BetterPrivacy-like extension has been made, but this really needs a whitelist like BetterPrivacy had so that it skips the ones you want to keep. Without it, this extension is risky to use.
