Mozilla Foundation report criticizes lack of advertising transparency on major platforms
Briefly

The ads libraries of major platforms like Facebook, Instagram, YouTube, TikTok, AliExpress, and Zalando lack functionality and are almost unusable, hindering transparency efforts for illegal or misleading content scrutiny.
Notable issues plague the transparency tools of companies like AliExpress, Zalando, Bing, Snapchat, and X, with restrictions affecting usability, such as Bing's inability to accept accented characters or Snapchat lacking keyword searches.
While Apple, Meta (Facebook and Instagram), and TikTok show better performance in ad transparency tools, challenges persist with errors in ad indexing noted by Mozilla and Check First, especially for TikTok and the Google (Alphabet) search engine and YouTube.
