Ok for about the last week my firefox has been acting up. Problems are: * I can not bookmark a site. * Keeps freezing on me. * I can not add the tab bar, well i can but every time i start firefox again it has gone. * Recently deleted some of my bookmarked sites. * Will only let me bookmark a site into a folder that i already had on there. (But it doesn't name the link, just puts a little symbol there) * Won't let me create new folders. I un-installed it and re-installed it but nothing changed, it still won't let me bookmark anything and it freezes every time i have more than 2 things running at the same time. It first started after my boyfriend downloaded some things onto my computer so i deleted all those files thinking it may have been those as he put the stuff he needed to fix his computer onto a disc but the problem is still there. I have scanned my computer for any viruses etc. IE is working fine for me but i don't like using that. Any suggestions guys?
