I upgraded my firefox browser and now I am Having problems are you?

I don't think you have to clean your computer. I have upgraded my Firefox for 2 months and I don't meet any problems until now. If you always get the errors and other warning information, you'd better make sure that if all you add-ons are working well. Sometimes, some extensions of old version may be not compatible with the new browser. We can get some interesting features with the help of Firefox's all kind of add-ons and plug-ins, but they may cause some accidental problems that lead our browser working with bad performance.

I have been having problems with Firefox all day. I have had two major viruses in the past two weeks, whether it came from there or not I am unsure. I usually have no problem with viruses but my internet provider, that we have had for 4 yrs, failed to notify us that we would not have virus protection until the 19th because they were switching to a new virus providor. Thank you, and talk about customer service. I am still very unhappy. Anyway I have Firefox 3.5 and I am honestly not sure if that is the most up to date version.

I have updated Firefox around 2 weeks back, since then I have found no problem. Actually Firefox hardly crashes or gives any trouble. If it crashes, or gives error message then it must be having some issues with your Operating System or any other system files in your computer. Try to uninstall Firefox and reinstall it again and see whether it gets resolved or not. If it does not, go to Firefox site and find whether there are fixes available for your errors. Otherwise the problem may be bigger.
