-moz-force-broken-image-icon

Firefox presently displays alt text for every broken image on the page. This may not be helpful for the purposes of debugging because the text may blend into the page. By using -moz-force-broken-image-icon, you can fore the broken image icon instead of the alt text

FireCSS: Gemeinsam am CSS schrauben

FireCSS klingt nach einem spannenden Konzept und einer sehr nützlich Erweiterung:

FireCSS is an add-on for Firebug. You edit CSS in Firebug. FireCSS sends the changes to any browser open on that page. When you’re done you can download the modified CSS files.

Zur Zeit ist es ein “proof of concept”, aber wenn es genug Interesse gibt soll es ein “actual (opensource) product” werden.

Firefox: Passwörter aus Bildern oder Text erstellen

Ein nettes Konzept realisiert das Firefox Plugin ObPwd:

ObPwd is a technique to generate strong text passwords from any web object (selected text, images, and URLs), or your personal digital content - such as your photos, audio/video files, and documents. You must keep your password generating digital object (local files or a pointer to web objects), but do not need to memorize the generated password. Using ObPwd tools, you can always re-create your password from your web content or files whenever you want.

Web Tracker Blocking

Ich teste gerade zwei Tracking Blocker. Für Firefox gibt es Ghostery was einen sehr guten Eindruck macht.

Ghostery sees the invisible web - tags, web bugs, pixels and beacons. Ghostery tracks the trackers and gives you a roll-call of the ad networks, behavioral data providers, web publishers, and other companies interested in your activity.

Und für Chrome Disconnect was nicht ganz so umfangreich ist.

Nevercookie™

Anonymizer veröffentlich Nevercookie™ als Firefox Plugin gegen den Evercookie.

Anonymizer Nevercookie simplifies this process and eliminates the manual steps required to completely remove Evercookies. And it does so without also removing all of the necessary cookies that a user actually wants to keep, such as those for browsing history and remembered logins. When Anonymizer Nevercookie is engaged along with Firefox’s private browsing mode, it quarantines an Evercookie and removes it after the browsing session.
