Dear firefox support, I have encountered quite a strange problem... I had flash working perfectly on my android device (samsung galaxy s5 g900f), that until i installed Addblock plus addon, since than i can't plat certain flash videos. I have tried to uninstall it from the tools>addon menu, but uninstalling did not solve the problem, flash videos still could not play with firefox on my device. So next i tried to uninstall firefox completely and reinstall it, that did not solve the problem as well. I have also tried to reinstall the adobe flash player, again that did not helped. I have tried to remove it manually through the about:config, again with no success. Is there a way to uninstall firefox completely from an android device so that the addon data will be removed as well? Any solution will be welcomed. Thank you, Mosbin
