On Careers 2.0, the technologies field (part of each experience entry under the Experience section) does not work properly on Firefox. Could this please be fixed?
It is very hard to edit existing entries, especially when there are many.
We recommend listing up to 5 technologies each for the Likes/Dislikes in the Technologies section:
Yeah, that helper text was temporarily broken, sorry - fix coming.
Editing a larger number of tags admittedly is a bit tedious right now, but it should work fine with only five or less.
I'm on Firefox (v25.0.1) myself, but I can't really reproduce this.
Clicking anywhere past the end of the tag list gives me a cursor at the end that lets me start typing a new tag. Clicking any of the existing tag names (anywhere except on the "X", obviously) makes that tag name look like normal text and puts the cursor at the end of the name.
The one part I can reproduce is the lack of a scroll bar when the length of the list exceeds the width of the box, which I agree is somewhat annoying. Then again, ordinary text input fields don't have scrollbars either, and I can still navigate the tag list just fine using arrow keys.
In general, the thing to realize about the tag entry boxes (including the Technologies boxes on Careers, as well as the ordinary tag entry box you get whenever you post or edit a question here) is that, despite their fancy appearance and AJAXy enhancements, fundamentally they're just plain old HTML
<input> fields with extra bells and whistles. As long as you treat them that way, they really work quite intuitively.
