If you hover over the URLbar, you get a tooltip that is the exact same width as the urlbar itself. This just looks wrong on short strings. The tooltip should resize itself to only fit the actual text and not have lots of whitespace.

I can confirm this. I mentioned this to rkaa last night and she said it has been happening for a few weeks, though I've only seen it for the first time last night on the 121921 build. I still see on 122008. Seen on Linux -> OS All.

Same on MacOS 8.6 Platform All.

Maybe this should be a new bug, but I report here as it is closely related. Tooltips also appear when one opens the URLbar dropdown and hovers over links therein. The tooltip is also always very wide, but what is even worse is that the text in it is nonsensical: it is the tooltip text which was last displayed when hovering over the chrome of that window, e.g. "Go back one page". If it is a newly opened page the tooltip is empty and very narrow. If the tooltips for URLs in the URLbar dropdown are needed at all, they should make sense. Otherwise they should be removed.

hewitt filed a duplicate bug on himself and fixed this; bug 116010. *** This bug has been marked as a duplicate of 116010 ***
