I just added a new theme for Google Chrome / Linux Chromium browser: meet Rocks4.

Navigate to https://www.techtimejourney.net/themes-old/google-chromechromium-skins/

Here is the Firefox version: https://addons.mozilla.org/en-US/firefox/addon/rocks4-persona/

My full Firefox and Thunderbird personas collection is also now added to the new Techtimejourney design. The section currently has 31 items – and more will come later.

The Firefox and Thunderbird Personas can also be found within the Gallery page’s top navigation bar.

If for some reason you do not see the personas section within the Gallery page then erase your browsing history – since you are more than likely loading an old local cached version of the page.
