Firefox crashes
Firefox has gone totally crazy. The little red box in the upper right corner is now blacked out instead of red, so I have to "feel around" to minimize or maximize the window. I cannot play any videos anymore, though Flash is installed. I've tried the clean install and to "refresh" to no avail. What's going on here all of a sudden?

hello omoya, maybe that's an issue with hardware acceleration - please try updating your graphics driver, or in case this doesn't solve the issue or there is no new version available at the moment, disable hardware acceleration in the firefox menu ≡ > options > advanced > general (that setting will take a restart of the browser to take effect).
You can also check for problems with current Shockwave Flash plugin versions and try this:
- check for updates for your graphics drive drivers
https://support.mozilla.org/kb/upgrade-graphics-drivers-use-hardware-acceleration - disable protected mode in the Flash plugin (Flash 11.3+ on Windows Vista and later)
- disable hardware acceleration in the Flash plugin
You can toggle this pref to true on the about:config page to disable protected mode in the Shockwave Flash plugin:
- dom.ipc.plugins.flash.disable-protected-mode = true
You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.
