Quite impossible to know but here are some ideas to try. I don't know how good you are with this computer stuff so I apologies if some of these are too obvious to you...
- uninstall firefox and delete manually all firefox directories (Cocuments and Settingsyour_user_nameApplication DataMozillaFirefox, Cocuments and Settingsyour_user_nameLocal SettingsApplication DataMozilla, Crogram FilesMozilla Firefox) before installing new version, sometimes uninstall lefts something behind. Take backup of your bookmarks first so you won't lost them. You can also check your registry and clean firefox stuff that uninstall left from there, but don't do it unless you are absolutely fucking sure that you don't mess up anything.
- Disable all add-ons you have installed.
- Get newest flash plugin, older versions are know to cause problems.
- If you are using firebug remove/disable it, I have heard that it causes problems in myspace sometimes
- Check if you system has Crogram FilesMozilla FirefoxcomponentsnsBrowserOpt.dll file. It's not Firefox file but some mallware/addware file that is know to cause crashes. Rename it/remove it and try if myspace works after that.
- If you are using XP try running Firefox on windows 2000 compability mode: 1. Close Firefox by opening the File menu and choosing Exit.
2. Right click the icon you use to start Firefox and choose Properties.
3. Click on the Compatibility tab.
4. Select Run this program in compatibility mode for.
5. Choose Windows 2000 in the drop down.
6. Click OK. Now that Firefox is set to run in Windows 2000 compatibility mode, it may no longer crash.
thanks for this, i'll try all of that
