Could also be a content-type issue.  If memory serves, your config is a "start-from-scratch" config because the Swiss Army Knife has too many knives.  Can you filter ANY .js files with your config?

They're supposed to replace:

/(?:reddit\.com\/r\/)(?<subreddit>[\w]+)(?:\/comments\/)?(?<postId>[\w]+)?/
/(?:reddit\.com\/r\/)([\w]+)(?:\/comments\/)?([\w]+)?/

And:

var s;const{subreddit:o,postId:r}=(null===(s=t.match(i))||void 0===s?void 0:s.groups)||{};
const s=t.match(i),o=null===s[1]?void 0:s[1],r=null===s[2]?void 0:s[2];

1st line is original, 2nd is replacement.

These both work as-is for me --

Ohhh, thanks for the hint! Putting application/x-javascript instead of application/javascript works. Both are considered legacy though (https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/MIME_types - Legacy JavaScript MIME types):

Note: Even though any given user agent may support any or all of these, you should only use text/javascript. It's the only MIME type guaranteed to work now and into the future.

Yup, I'm clumsy and don't want to cut myself. Those rules from the starting point config break JS left and right on that site.

Sure can, this was the odd one, all because of MIME type.

My initial hunch is that you have to 'escape' the "=" characters.

Yes, that would be better for consistency since expecting minified JS and escaped = is taken as literal without the added documented behavior.

Now I've put that MIME-List into use and added the following rule:

In = TRUE
Out = FALSE
Key = "Content-Type: Fix MIME types"
Match = "(*|(^?))$URL([^/]+*.([a-z0-9]+{2,5}&&$LST(MIME-List))((^?)|\?))"
Replace = "\0"

Threw out HTTP:// bit

[NotHereToPlayGames]

Out of curiosity, how many "filters" are you up to?

[UCyborg]

I currently use 14 filters in total.

[NotHereToPlayGames]

Ah, guess I assumed you were kinda building a new "swiss army knife", but I'd call 14 basically just site-dependent and not "global".

[UCyborg]

Oops, byte limit starts counting from where the match is found. Why did I bother counting preceding bytes?

I wondered why your filter limits were set so high.

[UCyborg]

Yeah, misunderstood documentation. I've put those two to 128 now.

Great topic, I'm a fan of Proximitron and Scott's godly work (sadly I'll never be able to meet him), hope you'll update this thread.

[UCyborg]

One thing that one would think would be simple...how do I write a Web Page filter that applies to "localhost" and "localhost/*.html"? If I write "localhost", then it'll match EVERY file coming from localhost, but I only want the root page and whatever other network requests for files end with .html.

[NotHereToPlayGames]

Hmm.  I haven't tried that and can't from here at work.

You can use header filters "inside" of a web page filter, only if the header is "true" is the web page filter applied.

[UCyborg]

Looks like I can use: localhost/ $TYPE(htm)

Had no idea about it - somehow this page was hiding from me: https://proxomitron.info/45/help/Matching-Commands.html (linked from https://proxomitron.info/45/help/Matching-Rules.html)
