Using -moz-opacity works fine though, suggesting the two properties are being handled differently. Reproducible: Always Steps to Reproduce: 1. Use this HTML snippet: <p style="font-family:Tahoma;">Delete</p> <p style="font-family:Tahoma;opacity:0.9">Delete</p> <p style="font-family:Tahoma;-moz-opacity:0.9">Delete</p> Actual Results: The middle paragraph clips the right-hand side of the text by 1px. Expected Results: All three paragraphs should be rendered the same, albeit the slight difference in opacity of the text. Editing the HTML, or CSS, live through FireBug or the Web Developer toolbar temporarily fixes the problem though.
-moz-opacity isn't supported anymore. It won't have any effect. The rest of this bug is likely a duplicate of another one, though I can't find it at the moment.
Created attachment 380453 [details] Screenshot of the problem enlarged by 500% Particular letters are more obvious than others such as the 'e', 'w', 'v' and 'm' but you can see the clipping is caused by a different anti-aliasing algorithm. The plain and opacity snippets are anti-aliased with color whereas the opacity snippet is anti-aliased with only grayscale and the final column is missing as you can see by comparing the 'e' in the sample.
Hello, this still happens in the latest Mozilla Firefox 3.5.4 for Windows. When using small font sizes and names ending in letters like 'i' this truncates the latest latter, creating a subtle bug which is really hard to trace.

This works for me on the trunk and Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2) Gecko/20100115 Firefox/3.6 Can reproduce using 3.5, would like conformation that the bug is worksforme.
