This used to be a good add-on, but last year they redesigned it to be basically non-functional unless you register for their services.
It also vastly slows down browsing; for me it was adding 10-15 seconds for EVERY page load, and significantly slowing down browsing within pages. This was going on for months, which I attributed to browser updates, but after removing this specific extension the problem was immediately resolved.

You can see in older reviews that they keep claiming this was a bug that they've fixed, which is clearly not true.
Do not install this. If you still have it installed from back when it was worth using, the sooner you get rid of it the better.

Now charged to simple security. Used to as a tracker. Suggest everyone remove this ASAP

Slows down Firefox. Leads to memory leaks and browser crashes. Probably engaged in hidden mining. The noble goal to secure the user is no longer pursued by the creators. Shame creators.

Useless add-on, all it does it promote it's "premium" option. On the first day of attaching it I was hit 10 times in the browser and received four emails about upgrading to the premium membership- whilst not receiving anything at it's basic level. As far as the add-on goes, there are much more open sourced, clear and honest add-ons that offer far more protection and cover that can be selected. I've now directed all mail from them direct to spam/ auto delete (as request to remove my profile has been accepted but ignored!)

I found out that this extension adds about 5 seconds to all page loads for me, which makes it almost unusable.

I don't know if this is due to another extension I have installed that is incompatible, but uninstalling this made my browser much faster.

体验越来越差

Just look one of their page:

24 reviews, NONE ABOVE 3 STARS but Wot "trust" this website and the note is 4 stars.
YES, 4 stars but NO ONE has given more than 3...

Seriously? This is shi*...

Pushing ads for some "protection service" it offers now. Sorry but F that. It was supposed to just show users the reputations of websites before you opened them. Now the extension itself feels as sketchy to me as the sites I'm trying to avoid.

As a long term user it is sad to see that this service has become so poor over the last 5-6yrs. Up to then it was reliable and had helpful & informative community. It is now very unreliable (inaccurate ratings,everything is broken and never repaired just changed for worse) & the community has disappeared off the forum. I think there are 2 forum members left from hundreds.
Developer here always say contact support.mywot.com, but no-one EVER replies, it's all just words to improve image.

I removed the WOT after I paid the fee. This Add-on caused constant crashes of my computer and was slowing down Firefox dramatically. Highly not recommended add-on!!!!!! Do not install it!!!!!

Последним обновлением всё испортили...
В подробности вдаваться не буду, всё рано у вас один ответ... всё хорошо, всё так и должно быть.
Решила удалить... к тому же достало принуждение обновится до премиум версии.
P.S.
Вы такими темпами всех пользователей потеряете, все ваши нововведения только отталкиваю от когда-то отличного расширения.
----------------------------------------
The last update ruined everything...
I will not go into details, all early on you have one answer... everything is fine, everything is as it should be.
I decided to delete... besides, I got tired of being forced to upgrade to the premium version.
P.S.
You will lose all users at such a pace, all your innovations only repel from the once excellent expansion.

German:
Habe Wot seit 10 Jahren genutzt, früher war es erstaunlich gut und habe jetzt durch das neue Update den Rücken gekehrt. Ich bereue nichts und bin froh das ich davon weggekommen bin. Die einzige Möglichkeit, die Bewertungen jetzt zu sehen, ist auf der Website. Für mich hat dieses Addon kein nutzen und besuche lieber https://www.virustotal.com/gui/ oder https://www.urlvoid.com/
English:
I've been using Wot for 10 years, it used to be amazingly good and now I've turned my back with the new update. I don't regret anything and I'm glad that I got away from it. The only way to see the reviews now is on the website. This addon has no use for me and I prefer to visit https://www.virustotal.com/gui/ or https://www.urlvoid.com/

Раніше активно використовував цей додаток, сьогодні планував його встановити і почав шукати, натрапив на опис у Wikipedia:

WOT Services has partnerships with Mail.ru, Facebook, hpHosts, LegitScript, Panda Security, Phishtank, GlobalSign and TRUSTe.

In November 2016, a German state media investigation found that WOT Services had secretly collected personal user details and sold or licensed this information to unidentified third-party businesses and entities for data monetization purposes. This activity breached the privacy rules and guidelines set by several browsers. As a result, the browser add-on was involuntarily removed from Mozilla Firefox's add-on store, and voluntarily removed from other browsers' add-on/extension stores. WOT was eventually reinstated.

On November 1, 2016, German public broadcasting station NDR reported the results of an investigation by in-house journalists, showing that WOT collected, recorded, analyzed and sold user-related data to third parties. The data obtained was traceable to WOT and could be assigned to specific individuals, despite WOT's claim that user data was anonymized. The NDR investigative journalism report was based on freely available sample data, and revealed that sensitive private information of more than 50 users could be retrieved. The information included websites visited, account names and email addresses, potentially revealing user illnesses, sexual preferences and drug consumption. The journalists also reconstructed a media company's confidential revenue data, and details about an ongoing police investigation.

German media contacted WOT Services with the results of the investigation prior to publication of the report. WOT declined to comment on the findings.

Тому ні, дякую, зашкварний додаток я не буду ставити.

Very biased ratings on any site that is conservative. Liberal sites are highly rated. I was checking out a site that I am familiar with because WOT rated them as a suspect site and I wanted to see why. There were 8 ratings, 6 five star and 2 one star. The average rating was THREE STAR. How was that calculated? The site was rated Yellow based on two derogatory tags and when I tried to rate it I could not access the rating system to comment. This site has been hijacked and is untrustworthy.

nothing but censorship disguised as something useful - absolute garbage

and if that isn't enough to dissuade you, read their "privacy" policy

to the developer:

users, as you well know, do not generally form unbiased opinions, something that can only be done through research and a lack of confirmation bias - thus, since this same user base is asked to vet content, WOT is useless at best ... of course i'm sure your shareholder(s) will disagree

Иногда такое впечатление, что люди отзывов в интернете совсем не читают)) Это вредоносное дополнение, не в смысле программной безопасности, а вашей конфиденциальности. Будьте осторожны, нельзя доверять.

Отзыв изменён. Ребята, похоже решили удариться в коммерцию и немного заработать на своём расширении. Чёрт бы с ними и с их жадностью, но расширение перестало работать, везде на любых сайтах выдаёт ошибку, а на некоторых просто гробит и замораживат браузер, система при этом тоже виснет из-за переполнения памяти. Очень похоже на незаконный майнинг за счет пользователей или того хуже, на вредонос. Удаляю и никому не советую эту шнягу устанавливать.

Too many times I am trying to reset the password and throwing an error. That leads me to ask, what are the limits to the characters admitted, and are there edits excluding some characters? I found no help to reset a password within the web page, and the help on the site is no help at all. What is allowed and what is NOT allowed in a password?

Dear user, thanks for reaching out. Please try using only letters and numbers, with no signs or symbols. Let us know if that works!

Thank you. That's just what I needed. I suggest that you add this information to your on-site help.
