In the past few months, maybe even a year, this extension has gotten really bad. The thing is, DeepL requires you to log in from only one location. So, if you use this extension and then open the site in another tab and enter the same login, either the site or this extension logs you out, and you have to log in again. This can happen many times in one day. The developers are not resolving anything. As a result, using this extension turns working with this translator into a complete nightmare. Moreover, considering that it's paid, and it already translates much worse compared to Chat.GPT or other neural networks, I'm giving it this rating.
