Summary: Do not recommend. This software badgers the user.

Details: I'm in the process of being more studious about my privacy. That said, I see no reason why a translation add-on needs any information from me whatsoever beyond the text I input or highlight to be translated and maybe some non-identifying use data to keep up on how the add-on behaves. I shouldn't need a profile or account. While I'm not obligated to have one to use the add-on, because I'm not signing up for one, the add-on has interrupted my browser use with a full-screen pop-up window to sign up with an account once per hour in the two hours I've had the add-on, and there was an exact one hour gap between the pop-ups. That tells me all I need to know about this add-on and what I can expect from it going forward, and I'm uninstalling it. Do better.

bait and switch tactic. turns out you must sign in to use image translation 'for free': 100 images PER MONTH

brilliant, simply brilliant. avoid like the plague

太垃圾扣扣嗖嗖

Antes funcionava, agora tem que pagar. Pessimo

我只想安安静静的翻译文本，一直弹出升级VIP……

越更新越难用，非要逼人充值我也是服了。不用你了不就完了

自动翻译关不掉，体验太差了！！简直就是让人抓狂

微软谷歌 也不免费了 还有流量限制 本来想花钱支持一下 你们这瞎搞我决定删除此扩展了 太垃圾扣扣嗖嗖

Ne fonctionne pas.

Je ne risque pas de payer pour une extension pareille.

It worked well up until not long ago where they changed from static translation services like bing/google translate to AI translate services hosted in China mainly or services you have to pay for like ChatGPT/Claude/Gemini.
I really liked it because it was convenient to use, but now you get prompted that you have to sign up after a bit because you've used their AI model too much and they want you to pay.
I've also noticed artifacts like often article titles will be translated into Mandarin instead of English.

Truly awful. It somehow decides you've reached a 'fair use limit' for a given day even if you haven't used it once. In two weeks of daily use I've seen zero use for this, and I would never reinstall it.

Its ad generation addon not translator. Get rid of it because it will constantly pester you to log-in and then to pay for premium so they can brag to investor how much people "engage" with their add . And translation is atrocious so **** them.

实际上一般，你收费这些都算了，免费的也不是不能用，可是我实在是搞不懂为什么你要去改页面布局？导致翻译出来的网站中一些按钮只能看不能点，真的是逆天，我的评价是不如火狐自带的翻译一根。

Useless application; it can't provide the usability they claim it has. Just a scam, with a lot of inside ads, basically adware. Even when I just wanted to use an external api like open router, ux is unbearable, and its only goal is to make you buy their subscription. So if you want an addon for translation, this one is not what you are looking for.

处处收费，吃相难看

用户量起来了，就开始收割，开发者是国人吗？就这十万用户量，也不知道你说的2000万用户哪来的。再见了，比你好用的还免费翻译不少的。珍重

I removed it since it started to set daily limit of free service and pressurize users to get monthly subscription. Disgusting!

Not actually free; many things that they advertised actually need a monthly subscription.

It's constatly saying im out of free translations when im not translating anything. annoying pop ups telling me to subscribe for premium when im not even using the extension. awful translations when they used to be much better even a month or two ago. its useless now, youre downloading it to get advertised to. Just use the built in google translate from firefox, it still works better than this. It cant even translate the chinese it advertises about, it turns it into japanese and russian at the same time somehow? deeply disappointing product.
