[Affected Versions]:

• Nightly 70.0a1

[Affected Platforms]

• All Windows
• All Mac
• All Linux

[Prerequisites]

• Have the latest Nightly RTL build installed or extracted.
• Have a Firefox profile with multiple saved logins.

[Steps to reproduce]:

1. Open the latest Nightly RTL build with the profile from prerequisites.
2. Navigate to "about:logins" page.
3. Observe the "Search" bar and start typing.

[Expected results]:

• The magnifying glass is displayed in the right part and the text starts from the right to the left.

[Actual results]:

• The magnifying glass is displayed in the left part and the text starts from the left to right.

[Notes]:

• Also, the "Search Logins" place-holder is displayed in the left part of the "Search" bar.
• Attached a screen recording with the issue.

This behaviour was implemented in bug 1567543 based on Ehsan's suggestion. It uses dir=auto so the rtl. vs. ltr. decision depends on the characters typed. When I test with RTL characters I see the magnifying glass move to the right side along with the text.

Ehsan, do you see a problem with the current behaviour?

I think the behaviour of the text box after the user types is probably desirable, but I do a couple of other issues:

• I'm not sure if the change in the text alignment together with the change in the directionality is really desired here. I think it's probably better to left-align the text (and the icon) in LTR builds and right-align them in RTL builds.
• The initial alignment of the textbox is wrong, it appears left-aligned whereas in RTL UI the user would expect it to appear right-aligned. (This is probably language dependant as far as the placeholder text goes, but not the icon.)

I have verified this issue and is no longer reproducible on the latest Nightly 70.0a1 (2019-08-20) (64-bit) on Windows 7x64, MacOS 10.14 and Ubuntu 16.04.

• The "Search" bar elements are correctly displayed on RTL builds.
