Good. Issues: It intrudes with localization warnings nonstop, even when turned off. Price calculation takes a lot of time. Mini calculator doesn't work. Spawns into edit boxes.

The convert works well on sites with a few numbers that it identifies as a currency. I can easily overlook the smaller challenges there might be when it guess the currency wrong and the fiddling with the settings to make it work as you want it to.

Unfortunately some pages takes a lot of time to load or process data, as conversion can take some time to process pages with multiple amount of prices, even to the extend that Firefox itself suggest disabling it when it identifies that a page won't load.

Eventually i got around to do a performance analysis since loading a product page in a webshop made my pc fans go into turbo mode. It appears that this extension used 97% of the CPU time when loading a product page with 17 items.
While it probably adds additional nodes in the DOM and not just calculate a number, I don't fell like 97% CPU usage in 6 seconds is a good performance result.

Nice clean and useful addon, well done.👍
i'll want to buy you a coffee

Clean, nice useful
EDIT: ok i found a couple of places that it does NOT work at all. it was one website tbf

Need to improve digits parser

i like this extension, toggling by hover + shift works great! unfortunately, the settings are ignored: "convert automatically on page load" and "show localisation alerts". i have these disabled, but it still auto loads slowing down the page, and it still shows me these pop-ups. for this reason, i had to disable it. would love for it to be fixed so i can enable this great extension again.

Works, but slows the hell out of page loading.

Very good extension. But some website cannot convert. Such as this one: https://detail.tmall.com/item.htm?spm=a230r.1.14.30.b804f5a3dU2hXQ&id=671734994635&ns=1&abbucket=14&skuId=5003219410178

Cannot convert CHY to AUD.

Didn't work for https://moto-tour.com.pl/en/

Doesn't convert from HUF
(Probably because in Hungarian it's abbreviated to Ft)
I would be incredibly thankful if it gets fixed :)

No matter how many times I check the settings to ensure that "Convert pages automatically on load" is unchecked, pages continue to automatically convert, slowing my browser loading time to an absolute crawl. I only need conversion for a few websites, not my entire browsing experience. Uninstalling.

Really slowed down page loads, and made pages with javascript updates run really slow... I'd love an extension that only activates when you highlight a text, and then shows result in a popup, like in Opera.

Installed and the first conversion I entered was not accurate. (usd to cad). According to xe.com 1usd = 1.26cad.. according to this addon 1usd = 1.3cad.. what gives?

update: Thanks for the quick reply. I found that option and fixed it. I'm surprised it doesn't default to the 3 or 4 significant numbers.. at 2 it's pretty useless.

Had to go to settings and change to GBP from USD. Great add on, does it when page loads up, and if you click the price, it shows original

Dramatically slows down the browser!

Great app all around. I had some problems with it early on (it is glitching on a few websites such as 4chan for me, so I suggest blacklisting those if you notice your browser slowing down), but it's an excellent app nonetheless

Okay but it's missing the most obvious option in my view unless I'm missing something. An on/off button straight from the top toolbar in Firefox. It's highly infuriating!
