Do y'all know about textise? I don't see mention of it come up in a quick search. https://www.textise.net/
It can be used with the duckduckgo bang !textise
It also works over Tor. And I have success using it as a proxy to avoid Cloudflare checkpoints.
I don't think that it is open source but not completely sure.
Copy from the site intro:
Textise is a new way of looking at the Web. It’s an internet tool that removes everything from a web page except for its text. In practice, this means that images, forms, scripts, adverts, they all go, leaving plain text. Find out more here... (https://textise.wordpress.com/about-textise/)
How to use this page
- Type or paste the URL of a web page into the box below and click "Textise". A text only version of the web page will be displayed.
- Type a search term into the box, select a search engine from the drop-down list, and click "Search". You will be taken to a text only version of the search results.
If you mean the official addon Firefox Translations (AFAIK there is no real native translation on FF, but let me know if I'm wrong), I just did a quick test and it seems to work.

Version 118 integrated translations based on this exact addon, I believe. Same project behind it, Bergamot
