The major disadvantages of using frames are: Bookmarks only bookmark the top level pages (the framesets themselves). A user is unable to bookmark any of the Web pages viewed within a frame. Frames can make the production of a website complicated, although current software addresses this problem.
iframe injection is a very common cross-site scripting attack. iframes use multiple tags to display HTML documents on web pages and redirect users to different web addresses. This behavior allows 3rd parties to inject malicious executables, viruses, or worms into your application and execute them in user's devices.
Frames (frameset) acts as document. It's removed because it breaks HTML documents structure and navigation. Eg. you have links in one frame, content in the other, you can't open link from the page in in a new window, you can't link to specific sub-page, etc.

There are various usability and accessibility issues with frames:
