slimjet browser not responding and thunderbird slow

[Valtam]

So what would happen if you opened just 10 tabs that were all the same ie. www.google.com ? Also what extensions do you have installed? Have you googled your browser version? It may have known issues. I know this happens with Slimjet depending on builds. One build can be fine, then the next build has issues, then the following is fine again. I'll get you to test an extremely light browser I made a while ago to see if it's Slimjet that's at fault. Will send the code later.
