Are there any addons that can filter and rewrite the DOM before it get rendered by the browser?

[pmjack]

I want to filter out stuff on sites before the browser get to it.

You can hide some elements from a website, but I doubt that you can block them if they come from the first party. I use uBlock Origin to block annoying elements.

uBlock Origin supports HTML filters.

Maybe that type of filter will accomplish what you want...?

Take a look at Modify HTTP Response, it allows you to change any kind of http response as you like.

uBlock Origin supports HTML filters.

Are you sure that HTML filters are supported in uB0 legacy? I always thought it was not.

Apologies, you're right. I didn't read carefully enough.

@JustOff
Thanks for this addon!

Is there any example of a working filter? I tried a simple one below, but doesn't seem to work:

Code: Select all

[["addons.palemoon.org",["/addon/modify-http-response/",["<h1>   Modify HTTP Response </h1>","<h1>TEST</h1>"]]]]

Doesn't change anything on that page. I also tried regex matching, but doesn't seem to work either.

[JustOff]

You need to properly deal with regular expressions:

Code: Select all

[["addons.palemoon.org",["/^\\/addon\\/modify-http-response\\/$/",["/<h1>[\\s\\S]+?Modify HTTP Response[\\s\\S]+?<\\/h1>/","<h1>TEST</h1>"]]]]

[pmjack]

Thanks it works now. I haven't have time to play with it, but what's the performance hit? Does it stop after find the first match or does it keep running until the end of document text?

[JustOff]

The extension itself has a fairly high performance, but the result depends on how well the filters you create are optimized, especially when using regular expressions.
