"Error initializing security header generator" on Kiwi browser (android)

This is unrelated to Twitter. Also you can ignore the message on Kiwi Browser if page loads fine afterwards, not sure why it appears in such cases since it's only meant to appear when page is stuck loading

tl; dr: firefox and other browsers block the necessary domains for old twitter to work, add abs.twimg.com to the urlclassifier.features.socialtracking.skipURLs key in about:config as a workaround

i think i finally figured out the answer. firefox, along with other privacy-oriented browsers, all seem to use a blocklist which includes twimg.com and every one of its subdomains.
for some reason, in firefox it seems like requests made in a non-authoritative context, such as requests made in extensions or webpages, get filtered through a blocklist regardless of the user's preference. at least in firefox, this filtering happens at a level low enough where the request is not even logged in the network tab of the developer tools. this made debugging the error almost impossible since fetch error messages are deliberately made as vague as possible in order to minimize attack vectors.

the only way i managed to get more details was adding a webRequest.onErrorOccurred listener to every request. this way, i managed to figure out that firefox was blocking requests to twimg.com because it was included in a list of social media trackers.

to fix this, i simply abs.twimg.com to the whitelist in the urlclassifier.features.socialtracking.skipURLs key in about:config.

currently not sure how to fix this issue in other browser, but it is almost certainly related to tracking protection features so maybe try disabling them.

Just disable the extension first then login then open the extension again

Weird. That's how I resolved mine.

Clicking Ok just loads Twitter like normal. So why would I disable it? It just adds an extra step when I want to visit the site.

I mean for me it logs out after a long time and that error pops up. Rn I really don't have to do it anymore. I only did it once or twice then yeah.

This seems to be an issue with Twitter too? Saw this post from a staff member saying that they're looking into it.
