URLs do not contain scroll position on the page.

Firefox has to work with the internet as it is, not the internet as we wish it were.

So do users. Keeping several dozen tabs open indefinitely decreases the stability of every browser. Computers have resource limitations. 95% of websites have bookmarkable links; use them.

Not Firefox, which is why I use it instead of Chrome. I am not saying tabs are without problems but they fit way better into my usage patterns than bookmarks.

This, I claim, is ideology.
