  • (2023-07-10) Abraham Toledo: my browser has being slow for months and I thought it was my internet. Untill I tried Firefox and it was lightning fast, the same happened in incognito mode. Then I disabled all my extensions one by one and this one for some reason is slowing down my browser a lot. If you absolutely need to use it, only activate it when you are going to use it.
