After disabling js I get a blank page in Firefox. Is that right? CBA to decipher the source or work out how to disable js in Chromium.
Here[1] is the link to disabling JS for a site in Chromium.
[1] chromium://settings/content/javascript
chrome://settings/content/javascript
I would suggest that most websites work better if you have javascript and CSS enabled, since that's what they were designed for, but use an ad blocker like uBlock matrix to remove the ads.
