Doesn't work on Linux? Rated 4 out of 5 stars

Installed v1.9 on Firefox 3.6.23 running on Ubuntu 10.04, but no icon or menu item appears anywhere, as far as I can determine. No mention anywhere in the description that it is incompatible with Linux systems or that it might require installation of additional support software.

Update: It does work on Linux when the instructions are followed, though it would be better if manual setup weren't needed. There are other cache cleaners and Firefox add-ons that place an icon or button in the GUI automatically.

This review is for a previous version of the add-on (1.9.1-signed.1-signed).

Did you read the install instructions?

EDIT: Well, according to API, Mozilla thinks it's better if you don't add the icon automatically to a toolbar.
