After trying out both options in post #2, I've found that option #1 doesn't seem to remember my settings, and reverts to 1 row almost immediately, and always after restarting Firefox. So I tried option #2, and it makes my PCU usage jump to 100% and stay there when the Stylish extension is active. Disabling Stylish drops my usage down to normal levels (when nothing else is running). Is this normal or did I do something wrong?
I found the extension UI Tweaker 1.7, but in the Toolbar Hacks options, the multi-row option is not selectable. Frustrating. The good thing about it is that it does compact the Bookmarks Toolbar, allowing more to fit on one row.
@ moab - Yeah, that's a good way to read your daily comics, but the ones I read are all updated on different days of the week, so this works for me. And there are extensions to create favicons in Firefox, trying using
this one.
