I have just completed my income tax return online. For this nothing but Adobe Reader will do. Unlike with other (free) Readers, I can delete/correct figures and text entered in fields, there are highlighted and 'interactive' form fields - eg. pop-up notifications if something was done incorrectly, and I can check the digitally signed security certificate. Evince of course is absolutely useless here. When I was still using Windows XP, pdfXChange Viewer was nice, but also useless for the task mentioned, and I am not keen on using Wine anyway. I grumble to myself because there is yet another 'extremely critical' flaw in Adobe Reader which is somehow interlinked with Adobe Flash Player. It is recommended to :- Disable Flash in the web browser. Disable Flash +3D +Multimedia support in Reader and to delete or rename these files :- "/opt/Adobe/Reader9/Reader/intellinux/lib/libauthplay.so" "/opt/Adobe/Reader9/Reader/intellinux/lib/librt3d.so" Although this is for Reader9, one is warned that other versions may also be at risk. Nobody really seems to know. See here http://www.kb.cert.org/vuls/id/259425 (and also check the Secunia site) A real pity regarding the availability of a decent alternative Reader for Linux.
