I confirm - that on Twitter there is an intermittent Firefox Alert on the top of the page saying Mate is slowing it down.
Any chance of implementing a way to switch Mate off on a per site basis.
Could be just a blacklist of sites written into a textbox.
5 stars when you do!

Muy buena. A mi me sirvió la traducción mediante el menú contextual seleccionando el texto deseado.

Baixei a extensão a alguns minutos atrás, mas já posso dizer que é excelente! Traduziu perfeitamente o que eu queria! Eu afirmo que é melhor do que o Google Translate!

Slows page loading speed. Mostly noticeable on Twitter.

Genial funciona muy bien.

Danke für den Hinweis! Tatsächlich geht es jetzt wieder wunderbar wie zuvor.
Ich hatte das schon neu installiert aber dabei den Firefox vor der Neuinstallation nicht beendet. Das war der Trick und wichtig.

Für alle wo es mit dem aktuellem Firefox 60.0.1 nicht mehr funktioniert: AddOn deinstallieren, Firefox beenden, wieder starten, AddOn wieder installieren.

Danach funktioniert es wieder.

Make it working again in 60.0.1:

Remove the AddOn, close Firefox, start Firefox, install the Addon again

It's very usefull, this help me very much

I give you 5 stars because I know how good this extension is... if it only worked with Firefox 60.0.1. Please, make it working again.

In short: as you should have already noticed, it's not working with Firefox anymore. Please fix it.

Stop working.

context menu does not work

Worked beautifully just a week ago, but after FF update, no longer works. At all. Also doesn't work on Opera or Chrome. Not sure whether it's the FF update or if there's some kind of bait and switch going on. Just two weeks ago one wasn't *required* to sign privacy and usage agreements. Looks like they initially offered their service for free, to grease the wheels, and are now trying to push users into privacy/usage agreements that allow them to collect usage patterns and expand their add-on as a synchronized service across multiple devices and platforms (except, apparently, Android). A cool service in theory, but in practice it looks as if they've somehow mucked this all up. in my own case, I didn't sign the agreement, and now can't access anything. Especially don't like the *not-optional* agreement that gives them to right to, you guessed it, turn you once again into the product... Am removing the add-on for now. Will check in during the next weeks to see what kind of product they want to be.
