非常不错的工具，very good
I tried to use this for throttling a single API call on a single site. I couldn't figure out how to get it to work. I had it set to current page only, and used URL Containing - my-api-call. It would not throttle until I set it to use all sites and all pages. Once I finally got it working and I was testing my API call, I disabled the throttle and refreshed the page...but it throttled everything. I deleted the throttle and it continued to throttle everything. I had to disable the extension to get it to stop throttling.
I had hopes from this extension but it has mostly been a disappointment. It seems like they spent a day on the UI and half the time it doesn't load and show the results only. Bad experience :/
Bunch of tools clubbed together with no common function. have some clear directions to use and not just vague text descriptions !!
Not a helpful tool, because it doesnt always run. The interface is not intuitive so the whole process seems very slow
Awesome set of tools from a wonderful company that makes the lives of developers and testers better. Love you!
A must-have for seamless cross-browser testing. Smooth interface, responsive testing, and secure data transmission. Highly recommended for anyone in need of efficient web testing!
User friendly and fast!
Nice UI & Options... And its without collecting private Data! +++
extremely helpful and easy to use.
