General :: Firefox Unstable And Does Not Do Streaming Video - Audio

running ubuntu 8.04 dual boot with windows- need windows for avery label program, ibm via voice and access data base .chose 8.04 because of long term support. firefox is now unstable and does not do streaming video ' audio.[ustream in particular and others] usually i get the video but not the audio. sometimes the fox just closes and i can open it on the second try- sometimes not. skype does work. there may be a fix for the audio using libflash support program. where to get this& what to do with it is a problem.

perhaps it would be prudent to upgrade to 10.04 but this seems to be a work in progress and might lead me into further problems. on the other hand i could work up to ubuntu 9.10 if it would be more likely to work better the get to 10.04 when it is further along. i am pretty useless with the command line.on the whole ubuntu has worked well until this problem came up.
