Fingerprinting lessons from 'curl-impersonate'
by a1ex＠dismail.de 01 Jan '25

01 Jan '25

Hi, There was an interesting post[1] on HN today about 'curl-impersonate', which is a patch[2] to curl which allows it to act like various big browsers, bypassing various fingerprinting techniques which would otherwise prevent the client from accessing the page. Looking at the patch, maybe there could be some useful ideas here for Dillo to use to load more sites. The SSL library also obviously plays a large role, maybe that's something we will need to consider as well. -Alex [1]https://news.ycombinator.com/item?id=42547820 [2]https://github.com/lexiforest/curl-impersonate/blob/main/chrome/patches/c…

Towards 3.2.0
by Rodrigo Arias 19 Dec '24

19 Dec '24

Hi, I'm planning to close the feature window shortly, so I will need to think what else to include for 3.2.0 before it is closed. One of the features I would like to include is the ability to open a link with an external handler. We have a proof of concept that uses the rule file, but I think it is too complex for now: https://github.com/dillo-browser/dillo/pull/199 I'm thinking it may be better to add an easier variant first, that we can extend later. I'm considering adding these to dillorc: actions="default Open with external tool" actions="firefox Open with Firefox" actions="mpv Open with MPV" actions="mpv-audio Open with MPV (audio)" handler="/bin/the-handler" Where you can define multiple "actions" but only one "handler". The actions have a label at the beginning (first word) and a human readable text that will be presented in the menu. Then, your handler will be invoked using the label as: /bin/the-handler <URL> <action-label> And you do whatever you find convenient in your handler, so you have more context to decide the proper action based on the label. I think this would cover most of the use cases of opening URLs with other programs without being too convoluted. Best, Rodrigo.

Hi all, I'm pleased to announce I will be going to FOSDEM this year to give a talk on Dillo and show it live (if all goes well). https://fosdem.org/2025/schedule/event/fosdem-2025-4100-resurrecting-the-mi… It would be the 25 year anniversary since the first Dillo release, and 20 years later since Jorge and Sebastian gave their talk at FOSDEM in 2005: https://dillo-browser.github.io/old/conferences.html Best, Rodrigo.

[PATCH] make downloads.dpi use http_user_agent from dillorc
by a1ex＠dismail.de 10 Dec '24

10 Dec '24

Hi, Here is a patch which allows wget called from downloads.dpi to use the user agent provided in dillorc, and fallback to the hardcoded Dillo/version agent if not defined.
