Thank you for helping make Firefox better. If you are reporting a defect, please complete the following:

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:78.0) Gecko/20100101 Firefox/78.0

What were you doing?

Please tell us what site you were on, and what steps led to the error you are reporting

  1. Hamburger menu > Customize….
  2. Drag and drop Profiler icon into Overflow Menu.

What happened?

What, if any, error messages did you see? Did the browser crash? Screenshots or screen recordings can be attached to this report and are helpful in isolating and replicating the bug.

Please refer to attached screenshot.

When profiler is not recording:
Icon location is flipped to the right side. Icon itself is mirrored as expected.
text is mirrored and placed next to the wrongly placed icon.

The icon and text return to their expected location when a profile is being recorded.

What should have happened?

Was was the expected result? ("Not crashing" may be a valid answer.)

Icon is placed at the left, aligning with other icons.
Text is not mirrored.

Anything else we should know?

Do you have extensions installed? You can also go to about:support in another window or tab and attach the report it generates to this bug.

My system and Nightly are en-US (LTR). I didn't test on a RTL locale.

Thanks for the report! My patch in bug 1621015 will fix this.

I'm submitting this as a separate patch as I plan on requesting for uplift.
