User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:50.0) Gecko/20100101 Firefox/50.0 Build ID: 20160704030211 Steps to reproduce: 1. Start Nightly in Windows 2. Open DevTools > Performance 3. Open the performance filter Actual results: checkbox and marker are overlapped. Regression range: https://hg.mozilla.org/integration/fx-team/pushloghtml?fromchange=975d97ff77ae82b113b66d2a46dc30fc654f411a&tochange=c0edf384327531b1e302c61fa3c77cf966152182 Expected results: Don't overlap checkbox and marker.

One thing to try is adding start padding on .menu-iconic-text then using a background-image to emulate the square (probably with a solid linear-gradient and a fixed background size and position).

Looks good on latest nightly Version 51.0a1 Build ID 20160810150918 User Agent Mozilla/5.0 (X11; Linux x86_64; rv:51.0) Gecko/20100101 Firefox/51.0 OS Linux 4.2.0-42-generic Can anyone verify ??

Ok, but is there different styling for different platform ? I mean different performance.css files ?

I have reproduced this bug with Nightly 50.0a1 (2016-07-05) Build ID 20160705030222 User Agent Mozilla/5.0 (Windows NT 6.3; Win64; x64; rv:50.0) Gecko/20100101 Firefox/50.0

As per the DevTools triage process doc [1], a P1 is defined as: - a security hole - causing data-loss - causing a crash - stopping the tools working - embarrassing Should be fixed within 24h and your manager should know about it and, between you, assign it to someone who can fix it. This bug has been set to P1 more than 3 months ago and is still unassigned. I don't think it's that bad that it needs to be a P1.

Hi I am interested in taking this bug. Please let me know if i can take this one or suggest other bugs as I am a newbie.

Hi I am interested in taking this bug.

Hey Irina, sure, please do! I added you as the assignee for this bug. The code for the performance tool is in /devtools/client/performance [1], but maybe the filter component is shared elsewhere. You can also find a lot of documentation about how to develop in the devtools codebase in [2]. I encourage you to follow the steps outlined in this documentation. I don't know the codebase well enough to give you directions, but I can have a look if you need it. Please add a "needinfo" request if you need anything.
