I like having telegram, messenger and whatsapp on the sidebar but is there a way to add Line messenger to the sidebar?

Is there a file (like urlist.txt) to edit the filters in Operas ad block?

Yes I would try that, it certainly will help

I had problems viewing videos in youtube with Opera, they would stop buffering after about a minute and resume automatically after a while, 3 to 10 minutes later. The solution was installing the extension YouTube Center now I can see the videos without pauses.

ublock
Its better and lighter than Adblock

Disabling opera://flags/#mse-h264-support still doesn't solve the problem, it doesn't load the whole video completely and stalls, I had to resort to install the extension "YouTube Center" and unchecked DASH playback

Opera 30
windows 7

For some reason opera Turbo seems to enable by itself after opera 30 update

Check if Opera turbo is enabled

Thank you
For months I had problems watching videos on YouTube, disabling opera:flags#mse-h264 solved the problem

Anyone else has this problem?
Whenever I play a YouTube video it stops loading midway and stays idle for like 3 minutes and then resumes.
I disabled all extensions and the problem still persists. This does not happen with Chrome or FF.

I Have a 1 Mbps internet connection.
