Firefox 8.0 freezes and is very slow. Please continue supporting Firefox 3.6.24 .
I am using Windows Vista , latest updates. I am using Firefox 3.6.24 and I am very satisfied with it. Some months ago, you offered me to download Firefox 4. I had done this. But afterwards, I could no longer see the TV on http://bugu.cntv.cn/ . Other people in China had said the same. I am learning Chinese and therefore do need to have this ChineseTV website. I reinstalled Firefox 3.6.24 and it works very well. Now in November 2011, after you had offered me several times Firefox 8.0, today I had installed Firefox 8.0 twice. But it is defective. Though now, it does play TV on http://bugu.cntv.cn/ . But the vertical scroll bar on the right side and the scroll bars in the middle on the monitor do not move (freezed) except when a website is enlarged on the whole monitor. The other problem is that Firefox 8.0 is slow, it is much slower than Firefox 3.6.24 . Please continue supporting Firefox 3.6.24 . It is better than Firefox 8.0.

Firefox 8 should be faster than Firefox 3.6 versions.
A possible cause is security software (firewall) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.
See:
Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
- Don't make any changes on the Safe mode start window.

Create a new profile as a test to check if your current profile is causing the problems.
See "Basic Troubleshooting: Make a new profile":
There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.
If that new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.

The slow / hesitant scrolling problem seems to be an artifact of the database Firefox uses to keep track of where you go, what you do, etc. It uses sqlite databases which get fragmented over time.
There are several fixes:
Some are add-ons and work internally, such as Vacuum Places (search the addons for it).
Some are external. Speedyfox is one I just tried, and found to work quite well. I think it did a better job than Vacuum Places, but requires Firefox to be shut down before it can work properly.
Find Speedyfox using a web search.
