Yes, I provided a great deal of info but I think it's better to do so than to fill it in later. 

Sorry for bad enlish. I got problems whit wieving Youtube filmclips on my computer. The problems occures from time to time and can of different kind: 1. Film "loading bar" shows up full (red) from start. 2. Fils starts normal and loads good but as the bar gets full the video stops (loading bar goes back to only half full) and i got the message "An error accured. Please try later". 3. Film starts loading but stops whit the error message above. A reload of the page CAN (in the best of worlds) fix the issue but don't have to do it. It's not a 50-50 shance anymore. I think it's down to 20% Yes, 80% no or similar. The other day, I totally cleaned out the internet history: Visited pages and downloads, Cookies and Cache. This did not solve the issue. (But I had to do it anyway). I always download the avalible Linux updates but so far no result. Yes, it's very frustrating and I need advice on how to solve this. No, I will not reset my web browser. It's the last option on my list. My FF: Ver 34.0 Flash: Ver 11.2.202.429 Computer Os: Linux Ubuntu 12.04 LTS 32-bit Ram: 1001 MiB CPU: Intel P 4 2.80 GHz x2 Internet: Wireless (no wi-fi or similar, just a wireless connection whit a modem in a USB port.) Yes, I provided a great deal of info but I think it's better to do so than to fill it in later. To be honest, the whole internet runs quite slow right now. That, however Can eventually have to do whit the great storm we had here last weekend. But my connection does work whitout breaking or other problems occuring. The Youtube problems did however start some time before the storm.
