Does private browsing enables webpages to access existing cookies?
If webpages can access existing cookies private mode is kinda pointless and just solves client side of the equation, webpages still know who you are if you already have cookies from them.

It doesn't happen.You can check this in the Net log in the "Web Developer > Web Console" (Ctrl+Shift+K). If you open a New Private Window and open the Web Console and open a page in this window to a website from which you have stored cookies then the request headers that you can inspect when left clicking the main page request shouldn't include send cookies the first time you open this page. https://en/Tools/Web_Console Solved?

If you enter Private Browsing mode then the current cookies are swapped to disk (cookies.sqlite) and a new set of cookies is created that is shared among all Private Browsing mode tabs and windows.
Existing and new exception rules (block, allow) are still honored and work the same in normal mode and Private Browsing mode.
Not related to your question, but...
The forum software detected your Firefox as version 21. Is that correct?
Version 21 is not secure; Mozilla discloses security flaws after each new release. Is something holding you back from upgrading to Firefox 24? Please let us know so we can suggest solutions or workarounds.
If Help > About Firefox shows Firefox 24.0, you may need to clear the preference that is misreporting your version number. See: How to reset the default user agent on Firefox.
