Unable to use 4chan (blocked by site) with Firefox for Windows for many months. Specific problem listed.

Hi Christopher, The message in your screenshot indicates that 4chan has temporarily blocked posting from your IP range because of suspected abuse. This is a restriction imposed by 4chan, rather than a Firefox error. Since you can use the site in Chrome, could you try opening it in a Firefox Troubleshoot Mode window? This temporarily disables extensions and some customisations, which can help identify whether something in Firefox is contributing to the problem. https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubleshoot-mode If the same message appears there, could you check whether you are using the same internet connection in both browsers? Also, does the problem affect browsing 4chan, or only posting? The distinction may help narrow down whether this is a site-side posting restriction or a browser-specific issue.
