i got an up date request from adobe, then ilost my clean print and amazon wishlist access on the address

bar i tried to reinstall [earlier versions] firefox. adobe installed a pdf app totally frustrated HELP!!! i think not sure version 12? ihad recently dowloaded photoshop etc about 20 adobe programs. for the last year i had the amazon wish add on which manifest to the rt of the arrows, and lft of the adress box. additionally the kodak clean print icon to rt of the amazon icon. a pop up widow appeared requesting an up grade for a pdf adobe program. as these update windows are as common as can be i complied it asked to restart, ok but when firefox rebooted it was a new version 19. the navigation bar had morphed the lft end was a circle with the address box running directly off the circle to the rt to the goggle search box. so there was no place for the amazon wish/ and clean print icons to live. and on the rt an adobe pdf icon had pushed the homepage icon to the right this app promised to covert any page to a pdf file, i went to tools and disabled 3 adobe add ons/ lost the pdf icon. i then tried to reinstall the amazon wish list add on got a message blocked by firefox/ hit allow restart then back to square one blocked by fire fox theclean print will also not reinstall??????/
