Our Facebook business manager Company and entire facebook account got hacked directly after installing this extension, and without resetting or changing my password and that's another proof that it was this extension since it has an access to the cookies, He used the cookies to access my account and removed all the members with full access to employee access then added his fake accounts and posted something that violates Facebobok policies to lead my account to suspension and now he spent over $1,000 from my accounts , Please be careful and I hope no one ever to experience what I been through the last days
Continues to be one of the key extensions that prove their worth in web work.
Great experience, really useful for all those who are really interesting and exploring different areas.
Ferramenta simples de usar e muito útil para, no mínimo, aquelas pequenas análises de sites que o desenvolvedor web precisa realizar sem onerar muito do browser.
Great tool👍
I've used this for around 15 years or more from the early Firefox days and probably saved a years worth of time using it. Better late than never sending a review :))
I love this extension! It's my go to when doing web development and I have to look "under the hood" quickly. It was down for a while, and I reached out to Chris and he had it back up and running with in a day. So so worth having in your tool box.
Amazing features
nice, now backtrack my url redirects for me and capture the nodes, and lemme give you a reward
good
