I’ve found a solution to bypass redirects and the mv2 manifest extension—which isn’t one of the four popular extensions hosted by Brave, as mentioned in the link. Thank you to the entire Brave development team and the moderators who helped me. Although it’s still a temporary solution, I’m very happy because “skip redirect” is one of many less popular mv2 extensions that are incredibly useful to me personally. With that, I’m closing this thread. I hope the Brave browser continues to improve in the future.
Additional note:
After trying the method based on instructions from Reddit, I realized that all mv2 manifest extensions installed from the Chrome Web Store are only active while the browser is running; when you close and then reopen the browser, the extension stops working even if you’ve used temporary flags. Finally, I found a concrete solution to keep the mv2 extension active in Brave for the latest update as of this writing: install it via the developer (offline) mechanism by downloading the original source code for the mv2 extension (.Zip) available on GitHub (example: https://github.com/sblask-webextensions/webextension-skip-redirect). After closing and reopening the browser, the extension remains active as long as the temporary flag continues to function in Chromium version 150. If you can’t find the offline source files for the mv2 extension, I recommend using this CRX Extractor/Downloader (https://chromewebstore.google.com/detail/crx-extractordownloader/ajkhmmldknmfjnmeedkbkkojgobmljda) and then downloading the .zip file from the mv2 extension page on the Chrome Web Store. I hope my experience can help resolve this issue.
