I am not fan of Mozilla Firefox and normally avoid using it, especially, after launch of Google chrome. But Now I need to use it as I have to test my websites and web projects in different browser. I updated the Firefox to version 29 and its looks surprised me. Mozilla finally leave behind its traditional look and adopt the new lovely User interface. This new look of Firefox is inspired by the chrome.
Fix Firefox Crashes
1. Type about:config into the Firefox address bar and press Enter.
3. Next , In the Search bar type browser.cache.use.
6. Close the tab and continue browsing.
After making this change, Firefox has not crashed a single time and it also feeling little faster than before.
Let me know if this small tweak worked for you. Happy Browsing.
