Great idea! Great way to learn new vocab on the go.

It's a simple but great concept, and it's showing results after only a couple of weeks.

The pause feature is also great for when you need to focus on important text without getting any foreign words.

I love the idea, but for me it slows down my browser so much that it is unusable, freezing my tab even on the lowest word amount setting. Will definitely come back and see if it works any better in the future

I actually came back to this and just stopped it running on the more taxing sites. Unfortunately these are the sites I use most, like twitch or any other chat room. But I can make some use of Toucan so i'll change my original 1 star rating to 3, hoping it runs more efficiently or has options to make it do so in the future

I really dig this extension/add-on. It is quite unique and not at all difficult to figure out, well, mostly. Great addition to my browsing experience for certain.

Thanks Taylor and crew! (if there is a crew)

Giving 5 stars for the concept alone as it is amazing and actually lets you just unconsciously soak foreign language just browsing the web. And it works. However, performance does leave something to be desired but i expect it to change soon.

Love the extension, love the idea behind it and I think it will keep being polished and getting better over time. The thing is, I am currently learning Japanese, in Microsoft Edge I had the change to switch to Kanji but I do not seem to find that option on Firefox...

Amazing concept but inadequate implementation. Instantly slows down certain pages (for example the interface of DiskStation Manager) to the point of becoming unusable. Firefox also notices this and asks me if I want to stop this extension from running. This, however, doesn't solve the issue. The only solution is to manually disable Toucan before visiting the problematic page. Can't add the page to the blocked sites because it doesn't allow adding IP addresses instead of domains.

Good idea, but
1) I could not feel significant progress so far (will report back in a few months)
2) as regularly mentioned, performance issue, especially apparent on sites like goodreads

Great idea and implementation is fine, But it doesn't work for me sadly. Even after changing the language in account settings page (and in the initial setup page) to German, it still changes back to Spanish in my extension. When I click Change in the extension, the page it takes me to shows the correct language (German). I tried restarting and reinstalling but sadly it didn't work for me. I would prefer if there was a way to de it directly from the extension instead of redirecting me to a page where the changes I make don't get reflected back. I'll definitely try it again in some time because I love the idea, the implementation could do with a little polish.

Good

Toucan is an excellent concept. Unfortunately, the implementation suffers from severe performance issues, typically on websites with a large amount of content and particularly so when large amounts of content are updated by a script (you can see this very well on api.rubyonrails.org when searching).

This addon works as it says. One caveat (at the time of writing) is that sometimes it slows down the browser to a standstill. I've been told, that they're working on it though, so one can hope. You can disable it on specific sites, or entirely, if you do not want to deal with it for a while.
