[Solved] I just recently caught on that my Update Manger lists a suggested 43.2 MB installation of Chrome every time ( or almost) it runs. But I already have Chrome installed and I use it occasionally. I have a hard time believing that Google is updating their browser once or twice per week. I realize I can uncheck it to run in Update, but it made me wonder if to do so I would be missing some security update. Now today, it has decided that I should install Mozilla Firefox (again) for another 26.7 MB and Opera for 13+ MB more. All of these browsers cannot be issuing updates on a daily basis. What is going on with Update mgr? Cut out the browser updates and everything else loads in about 3 minutes.
I'm running Ubuntu 12.04 on a desktop and have all 3 browsers installed but use FF about 95% of the time, Chrome 5% and Opera almost never although 6 months ago it was my default browser.
