10.0.2 Firefox crashes on startup
To solve this problem you have to go through some steps. All of them are given in my comments. Uninstall your Firefox first then clean your cookies. Therefore, no history will be there. Then download a brand new copy Firefox (latest version). Make sure that your downloaded Firefox is not broken file. Sometime downloading stop at the middle and file become broken. So be careful with it. Then install your downloaded latest version of Firefox. Ohh restart your computer before install downloaded latest version of Firefox. Follow these steps.
I hope your Firefox will not crash anymore. If you don’t know any site from where you can download latest version of Firefox then just search Google.
You will get it.
