I've been using the ff. addons for Firefox following advice in various threads, and sometimes (maybe around 5 pct of sites) I still get newsletter and cookie popups or content (either embedded videos or the page text) not showing up, and to solve that I had to either figure out which script options to block in uBO, block specific elements, activate a filter list in uBO, or whitelist one of the addons. I'd like to know if there's a way to streamline the number of apps and filter lists used and minimize breakage. I've been using the ff.
CanvasBlocker - yesterday, the yellow bar showed up for one site stating that it was slowing down the browser; in forum comments, I think it was pointed out that there's something wrong with the code in the site, and there's nothing they can do about that; I can't see a quick way to whitelist a site in the toolbar button.
ClearURLs - I used to search for an image in Google, and middle-click one result to see it in another tab. Know, everything only point to the Google page. I disabled the addon filter and cleared the cache but the problem persists.
CookieAutodelete - I think this one is fine, although lately even with Youtube whitelisted when I open the browser and go to Youtube, settings for disabling autoplay and turning on dark theme revert to default;
CSS Exfil Protection - I think I disabled it for one site but can't remember the details.
HTTPS Everywhere
LocalCDN - I had to disable it for around seven sites, and I just found out that I had to (I think) generate a rule set for uBlock Origin;
Nano Defender - I followed instructions to make this work with uBlock Origin. I can't remember seeing any "disable adblock" warnings lately, although I'm not sure if it's because this is working or something else is blocking those;
Privacy Possum - I remember disabling this for a few sites, but I can't remember which ones.
Privacy-Oriented Origin Policy - I had to whitelist two sites.
uBlock Origin - I tried to follow the advice given in a recent set of tweets, so I used it in default mode but with the ff. filter lists - my filters (containing mostly elements for banner ads and cooking and newsletter notifications that weren't blocked by thei lists), all built-in filters, for ads Adguard Base (which blocked ads in one site) and EasyList, EasyPrivacy, Online Malicious URL Blocklist, Adguard Annoyances (blocked popup notifications in one site), Easylist Cookie (blocked cookie notifications in some other sites), uBlock Filters - Annoyances (blocked annoyances in another site), and Peter Lowe's ad and tracking server list. The total's around 90k network and 110k cosmetic filters. I had around a dozen other lists in the custom section but they are all disabled.
Finally, I installed Pi-Hole with the OISD blocklist (around 1.2 million domains), and it reports around 5% of queries blocked, with one site that had to be whitelisted. In two or three occasions, one or two websites loaded faster when I switched to Cloudflare DNS using DNS Jumper in Win 10.
