The floss forges have blame also eg https://codeberg.org/Codeberg/Documentation/blame/branch/main/README.md but idk if it is exact pair to github. There’s probably some vs code alternative.
I wonder if find works properly if you use their version of find rather than native browser. It takes over typeahead find in a super obnoxious way which Firefox seems unable to prevent. Maybe they just aren’t supporting the native find. Though their in page hijacking never works properly. Maybe you need a nicer device.
You can usually prevent hijacking with a setting in about:config
I use it to prevent clipboard hijacking, for example
I have looked and looked I don’t find anything that actually works. The setting that’s supposed to do it doesnt.
I wonder if it’d be possible with ublocko to disable the specific JavaScript but idk how to do it.
