Version 0.4.7-pre3 Ohodnoceno 5 z 5 hvězdiček

Why is impossible install the 0.4.7-pre3 version on my Firefox 36beta?
The button is gray and say "Not available for your platform".
Thanks.

EDIT: Firefox automatically update to last version, but not manually with the button on AMO site.

Update Ohodnoceno 5 z 5 hvězdiček

In Aurora 29 and Nigtly 30 with Australis the icon disappear in toolbar after the Firefox reboot, in addition in customize mode appear the text name in place of icon.
Please update.
Thanks.

EDIT: I found the culprit:

You can fix this?

Great tool Ohodnoceno 5 z 5 hvězdiček

Finally a perfect and automatic Cookies Manager.
The extension however, takes about 2.5 Mb.of RAM, is possible decrease this parameter?
You can check this with the extension "about:addons-memory"here: https://addons.mozilla.org/en-US/firefox/addon/about-addons-memory/
Only a one cosmetic suggestion, maybe is better a throbber effect for the icon when the cookies are destroyed.
Thanks.
