User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:50.0) Gecko/20100101 Firefox/50.0 Build ID: 20160607071209 Steps to reproduce: 1. Start Nightly in RTL locales 2. Open DevTools > Netmonitor 3. Go to any sites (e.g. https://bugzilla.mozilla.org) 4. Open requests-menu-stack-trace popup (mouse over on [JS] icon) Actual results: File name is not displayed fully, because ellipsis position is in file name side. Expected results: Change ellipsis position. or... in case of the Browser console in RTL locale, direction is not RTL. If apply same specification to requests-menu-stack-trace, its direction should be LTR. Please refer to attached image.

Thanks for the report! Jarda, this is related to the new feature you've been working on. Can you please take a look? Honza

I'll be migrating the tooltip from XUL to HTML very soon (and maybe also to the frame.js React component), so I'll take care of this in the process.

The issue was partially fixed when we converted the stacktrace tooltip from XUL to HTML in bug 1277264. Now I'm adding the final step: add a "direction: ltr" rule to the stacktrace container element (.stack-trace-tooltip). I.e., the same thing that is set on the console output at [1].
