Page 1 of Got Firefox & Avast? Probably not for much longer
This is a little concerning
Wladimir Palant, creator of AdBlock Plus, published an analysis of Avast extensions in late October 2019 on his personal site. He discovered that Avast's extension transmitted data to Avast that provided Avast with browsing history information. The data that the extension submits exceeded what is necessary to function according to Palant.
The extensions include the full address of the page, the page title, referer, and other data in the request. Data is submitted when pages are opened but also when tabs are switched. On search pages, every single link on the page is submitted as well.
Reason enough to avoid Avast, or at least remove the browser extension.

Avast is fine really but certainly don't use the extensions.
We will pay the price but we will not count the cost..
