Please don't lacerate me just at once!
For more than a decade now I'm used to have open about 20 to 40 (or even much more) tabs at the same time and being at least as fast as a new PC when having turned off scripting ... with PC running WinXP having not more than 512MB of RAM on a machine with Celeron or P-III at 1200MHz.
How to do that with K-Meleon in a way that virtual memory does increase so much that K-Meleon gets unresponsive and you have to wait for tens of minutes (up to half an hour) until you can touch that PC again (because of swapping of virtual memory)?
Btw: increasing physical RAM is NO option as the used PCs do not allow more!
