I can not use Yahoo Mail at all. All links to commands are dead since 97 update. YouTube has been full of glitches for over 3 months. Playlists crash. Dead links like in Yahoo mail. Can not search channels with keywords. All these issues are limited to Firefox. Chrome works fine but my data didn't properly import from Firefox so logins and bookmarks are a pain because on nonexistence in Chrome. Having to look up login and passwords in one browser to use in another is a major waste of time. My business is being damaged by the lack of ability to send or receive communications, especially attachments. I have been unable to order from vendors that I normally send files to for production. Please help!
