This might not be I bug but a bad XML parser but I better report it. I did some research of the problem and it seams that renaming downloads.rdf in my profile directory fixes the problem. downloads.rdf is 3.92Mb big and spends more than 5 secs full CPU time to start a new download. Meanwhile mozilla is not responding. About 10 seconds is taken to remove a single entry from download list on my Athlon 1.7Ghz. I've also found that there is a xml tag with many children in the middle of the file: <RDF:Seq about="NC:DownloadsRoot"> <RDF:li resource="E:\Download\books\ArtOfOS.html"/> ..... (more 7000+ children) ..... </RDF:Seq> Reproducible: Always Steps to Reproduce: 1.Make your donwload list BIG > 4Mb (about 80000 lines) 2.Try more downloads 3.Try to remove downloads Actual Results: 100% CPU usage and at least 5 second mozilla not responding on 1.7Ghz Athlon Expected Results: Work much faster :)

I noticed this to. Mine is 2.6MB's in size. What appears to be quite a few downloads. I'm using a 1.8GHz P4M laptop with 1GB RAM. Freezes for a few seconds with 90% CPU on Mozilla What's interesting, is it takes about a +5MB in RAM to delete an item. Some is released, but each time it grows. I delete several items, and I find I grew an extra 10MB's of RAM usage. I think the solution would be to have Download Manager eventually delete items after say 500 by default. I'll mark as new, since I see no obvious dup. I'm not sure if this is a bug though. What can you expect with a 3.92MB's download RDF data?
