Some sites will present you a Flash site if your browser tells the site that it has?Flash available, and will present a fully-functional non-Flash site to browsers that do NOT?have Flash.
If these are not sites requiring a registered-user login, and if you were willing to?tell us the sites, we could test them for functionality without FLash.
For example, I removed the last traces of Adobe from my computer 2-3 years?ago, and do not feel I am missing anything on any websites I have gone to in?the interval.
Eventually I succeeded in force quitting the installer in Activity Monitor, but?that didn't solve things. I couldn't eject the disk image.
Re-boot.
The mounted disk image should be gone, although the .dmg file it mounted?from will still be present.
I tried to restart the computer, but it wouldn't let me do so till I quit the?installer, which I didn't succeed in doing.
You can always just use the On/Off button¡
Finally I managed to shut down the computer with the button on the back,?and then restart it.
See? <grin>
