The new pinned badge in bug 1631844 is gray and is hard to recognize as a pin, at least on my dark mode configuration.

This was on Firefox 75, on macOS Catalina 10.15.3. Both Firefox and macOS are set to have Arabic UI.


Actual results:

The left border moved.

Bug: [Meta] Users seem to be unexpectedly be signed out of their FxA

Resolved: 2020-10-04 18:32:48+00:00

Over the last couple of months, we've heard a couple of times users being unexpectedly signed out of their FxA on desktop and having to sign back in. 

I thought we could start collecting/documenting when this happens in this bug, to see how often people are reporting this and if there are any common patters with the users browser set up that might be causing this. 

Most recently we saw a note from Selena's friend being occasionally logged out: 
"Related: I now have a growing list of like 10 destinations to send tabs to, despite having only ~4 devices with Firefox on them. I think occasionally I get logged out and when I log in again am prompted to type a new name? And all names old and new are kept forever?
Come to think of it, most syncing of state seems fine. It's only the "send tab to.." system that feels unreliable."
Bug: Pressing Ctrl while the view is open and there's a match to an opened tab makes the view list bigger, when 2-line layout is active

3. Open google.com
4. Open a new tab, start typing `g`
5. See the "Google - Switch to Tab" item from the list
6. Press Ctrl (like you'd want to open that item in that same tab without switching to the existing tab)

AR:
The url itself gets in a new line beneath the title, making the view bigger

Not sure tbh, but I don't think the view getting bigger is a good UX.

STR:
1. Latest Nightly, install a Hebrew/Arabic lang pack to fully observe the issue
2. Set `intl.uidirection` to `1` and restart
3. Open any normal LTR url
4. Open a new tab and unfocus the urlbar
5. Go back to the first tab
6. Go to the second tab
7. Observe the url placeholder text

AR:
The text is in reverse. Focusing the urlbar makes the text readable until you unfocus.

ER:
The text should be readable and not treated as `direction: ltr`.

This is caused by this:

but the root of the problem is that `domaindir` is still `ltr` when going back to the new tab.

Bug: Search bar sometimes fails to suggest opened tabs

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:76.0) Gecko/20100101 Firefox/76.0

Steps to reproduce:

While having several windows / tabs open, I sometimes forget that a page I want to load is already in an existing tab.

So I start typing the domain name, or words from the title of the page, inside the search bar, to find it in history.

An example, I wanted to view https://docs.gitlab.com/ee/user/project/repository/repository_mirroring.html and types "gitlab" in my search bar.


Actual results:

Sometimes, the existing tab is suggested.
Other times, the existing tab is not suggested, even if the searched keyword is present in the tab's title or domain name.

In this case, after typing "gitlab", I received 4 suggestions for queries ("gitlab", "github", "gitlab ci", "gitlab api", ...), and 5 suggestions for past pages I had viewed but were not currently opened in existing tabs.


Expected results:

The opened tabs should consistently be suggested above other search suggestions if they fit the description.

Noticed that if i had caps lock enabled on my machine, I was getting different search suggestions -- more importantly, I wasn't getting the search suggestion I was looking for.

When typing in FIRE vs. fire, I seem to get only open pages or bookmarked pages in my suggestions. 

The suggestion I am looking for is `https://www.reddit.com/r/firefox/`, which doesn't appear when I type FIRE. 

Here's a profile of me trying it both ways - first with `FIRE`, next with `fire`.

Steps to reproduce:

I start my browser (start first time, or use the browser first time)


Actual results:

the browser tries to guess my country. and do some (stupid) settings for country that it has guessed. OF COURSE this mechanism canNOT work correctly in 100% of cases (!!and you know it!!). it's defective design!


Expected results:

browser **must ASK ME** what is my country (dialog window). NOT TRYING TO GUESSING this important information.

could I use VPN?

could my provider have invalid records geodb for its ip-addresses? could my mobile roming work strange? (for exmaple -- mobile operators that works with Israel Partners for worldwide support)

could I be in trip (to another country)  when I'm starting firefox?

could I have homes in various countries? triple citizenship?

could I hate my native country, therefore hate the country's settings? Is it not legal to see (use) what settings in another countries?

you, developers, decided that Firefox should have varios settings for various countries. it's really UGLY SHITLY DESICION. and you made in in implicit form, which is yet worse.

honestly speaking (ideally) I think settings must NOT be verious for various contries. if you want to make a special solution for Russion Federation (for example) -- make a fork -- Firefox-russan-edition (or firefox-dictators-edition or e.t.c.) , or special options for COMPILE TIME "--enable--dictator-mode" .

you should NOT making tests for experimental features -- according to user's country.

"let's try DNS-over-HTTPS on USA users"? WTF?! you have beta edition!
 do your tests on beta edition! if you want to make some tests -- make it evenly on ALL COUNTRIES on all people around the world.

"lets do for dictator's countries -- search engine Yandex (known for his loyalty to dictators)"? WTF?! how many Yandex gave you money? are you really putin's bro?!

and what about privacy, the privacy-by-default is respected only for USA? are'nt you NAZI, are you? but we (peolple of the planet) have the same internet-protocol?! the same www-standarts?

when I try to read pices of advices for Firefox  settings -- I cannot do it, because various Firefox installations (started various contries) have various default settings. WTF?!?!

in full solution (ideally) -- in settings should NOT be any mentions about the user's country!! AT ALL NO MENTIONS ABOUT THE COUNTRY! default settings should be THE SAME in all countries!... (until users use the "Mozilla Firefox", not "firefox-dictators-edition").

but ok! ...if you can’t give up doing varous settings for variuns countries -- than you MUST ASK about "what's your country?" IN EXPLICIT FORM from a user.

thanks in advance! :-) .. and thanks for reading. I hope you understand how important it is.

Notice how the title element contains a RTL override character. That's probably alright and worth supporting, but as soon as we add information to it (e.g., "(pid 12345)") in Nightly versions, we should probably enforce the direction for our content.

I initially used context for the "Subscribe" string. Made sense from a semantic pov, but that field isn't configurable in the ad server.

Next best thing that is available in the ad server is excerpt, so we should move over to that.
Bug: Enrolled client_id with missing experiments field in messagingsystem.onboarding db

Large number of enrolled users in beta pull factor experiment  are missing experiments info in the messaging_system.onboarding db.

https://sql.telemetry.mozilla.org/queries/70549/source  shows users  who were enrolled, didn't see about:welcome and later has telemetry pings without experiments info.

We should improve logging at following places to rule out race condition between RemoteSettingExperimentLoader.init completion and PingCenter.jsm which reads active experiments

RemoteSettingsExperimentLoader.init() -> ExperimentManager.onRecipe -> enroll -> setExperimentActive
