**[Affected versions]:**
- Firefox Nightly 115.0a1 (Build ID: 20230518213154)

**[Affected Platforms]:**
- Windows 10 x64
- macOS 12.6.1
- Ubuntu 20.04 x64

**[Prerequisites]:**

- Have the Firefox Nightly 115.0a1 installed.
- Set the following prefs:
`browser.urlbar.weather.featureGate` = `true`
- (Windows only) `browser.urlbar.weather.ignoreVPN` = `true`

**[Steps to reproduce]:**
1. Open the browser from the prerequisites.
2. Type the “weather” string in the Address Bar.
3. Resize the width of the browser to minimum.
4. Observe the weather result.

**[Expected result]:**
- The weather result text is correctly wrapped and displays a fading effect at its end.

Bug: URL bar suggestions: "Open menu" button activates inconsistently with Space
Status: NEW
Priority: P3
Created: 2023-05-19 13:10:21+00:00
Resolved: 2024-02-27 18:52:42+00:00

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:109.0) Gecko/20100101 Firefox/113.0

Steps to reproduce:

Typed into URL bar such that Firefox Suggest and/or search history results appear. Used Tab to focus the individual "Open menu" (meatballs) buttons.


Actual results:

When pressing Enter on a meatballs button in Firefox Suggest or search history results, the menu was opened.
When pressing Space on a meatballs button in Firefox Suggest results, the menu also opened.
**However**, when pressing Space on a meatballs button search history results, the suggestion text instead went into the URL bar with a space character after it.

Also:

When a meatballs button is focused under Firefox Suggest, the URL bar goes blank.
**However**, when a meatballs button is focused under search history, the URL bar still contains the suggestion text.


Expected results:

Navigation effects should be consistent between Firefox Suggest, search history, or anything else placing an (identical) meatballs menu button into URL suggestions.
Bug: can't change default browser

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:109.0) Gecko/20100101 Firefox/113.0

Steps to reproduce:

Hello.
My system:
xfce4 4.18.2
Linux 6.1.28-gentoo x86_64

My programs:
firefox-bin 113.0.1
google-chrome 113.0.5672.126

xfce4 has the default browser google-chrome.
In xfce4 settings -> Default settings -> google-chrome browser is selected.

$ xdg-settings get default-web-browser
google-chrome.desktop

egrep 'htt|bro' ~/.config/mimeapps.list
x-scheme-handler/http=xfce4-web-browser.desktop;
x-scheme-handler/https=xfce4-web-browser.desktop;
x-scheme-handler/http=xfce4-web-browser.desktop
x-scheme-handler/https=xfce4-web-browser.desktop

If you go to the settings of firefox -> General -> then I see that firefox is listed as the default (Currently, Firefox is your default browser).


Actual results:

The problem is, I can't change the default browser.
I want to make google-chrome the default browser.

Of this, google-chrome becomes the default and firefox also remains the default.

In the telegram messenger, links/url open in firefox.
In the Skype messenger, links/url open in google-chrome.


Expected results:

I want to completely set google-chrome as the default browser. 
Removee feature in firefox default browser.

Bug: Bookmarks go hidden after going fullscreen and deactivating it while address bar is activated
Status: RESOLVED
Priority: --
Resolution: WORKSFORME
Created: 2023-05-20 14:15:35+00:00
Resolved: 2023-06-16 07:33:05+00:00

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:109.0) Gecko/20100101 Firefox/113.0

Steps to reproduce:

First of all, this only works when you have enough many bookmarks. Meaning that a double arrow pointing to right is shown. (See the attached screenshot for reference.)

1. Activate address bar by clicking with mouse
- (Doesn't matter how you activate the address bar, as long as you can see it highlighted on the edges)
2. Activate fullscreen mode by pressing F11
3. Deactivate fullscreen mode by pressing F11


Actual results:

When following the reproduction steps, bookmarks stay hidden behind double arrow "menu". But to get bookmarks showing as normal again you need to reactivate bookmark toolbar for example by pressing Ctrl+Shift+B key combination twice.


Expected results:

All the bookmarks should be shown on bookmark toolbar as normal after reproduction steps. But it doesn't show them since there are so many bookmarks.

Firefox for Android

Steps to reproduce:

I have been using Firefox (always up to date) on a Laptop for a while now and use Sync too because I want to have access to my bookmarks on my phone seamlessly too.
My Laptop got old and inadequate so I changed it this week.
I've installed Firefox and logged in.
On my old laptop I sync my Bookmarks, Settings and Add-on only.


Actual results:

I actually did got my booksmarks back and Add-on back.
However, this is the only thing I got.
I do actually have 11 Logs for Sync errors.

By digging a little deeper, it turn out that it's the same on my phone. I only have the Bookmarks.


Expected results:

Things I was expecting to see Sync that are not (only what I'm sure of): 

My preferred language and appearance
Cookies and Site data Exceptions (Biggest Issue)
My history setting (Second biggest issue)
My theme and 
Toolbar customization was not the same

Steps to reproduce:

We have Firefox-ESR in use and we are using Applocker. 

When we enable applocker dll Rule policys and start https://shaka-player-demo.appspot.com page clearkey addon crashes. 

We have allowed widevinedrm.dll in applocker rule policys, and we have used Process Monitor to track which dll file / files are being "locked" but we cant seem to pinpoint it. 

Where does Firefox-ESR run DRM content and which dll files are needed to run ? 

What we know that it is caused by applocker DLL rule policys, when disabling it clearkey addon does not crash and drm content can be played. 

Also Applocker eventlogs does not show anything related to this.



Actual results:

Clearkey addon crashes


Expected results:

clearkey addon should not crash and and drm content should be played.

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:102.0) Gecko/20100101 Firefox/102.0

Steps to reproduce:

I am a heavy tab (ab)user and have ~3000 tabs open across 5 windows. The largest has ~1100 tabs open, and I accidentally closed it (alt-f4, no prompt "are you sure?") while viewing a blob: url in pdf.js. Once it closed, I went to history> recently closed windows>(that window name), and it started to restore


Actual results:

It took a long time, with memory usage going in a ~2 minute cycle between 8GB and 16GB, before crashing with OOM. Restoring Fx only restored the 4 windows, but I could again go to history to re-open the 5th window, but again it used lots of memory and OOM's again. This repeated several times.


Expected results:

I edited the session backup.jsonlz4 file to delete the offending blob: tab, and moved the closed window from "_closedWindows" to "windows" (plus other necessary fixups), and all 5 windows opened normally using under 1GiB of RAM

When we setup the sponsored topsites from Kevel, we set the favicon, but not the favicon size.

The code expects both, and without size, it assumes we don't have a valid thumbnail so takes a screenshot.

Bug: Firefox opens last 2 windows instead of only the last window when opening
Status: RESOLVED
Priority: --
Resolution: FIXED

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:109.0) Gecko/20100101 Firefox/113.0

Steps to reproduce:

Open 2 websites in 2 Firefox windows (1 in each). Then, in about:preferences, activate "Open previous windows and tabs". Now, close 1 window, then close the other window (which factually is the same as "exit Firefox"). Now that Firefox is completely closed, open it again.


Actual results:

The last closed window opens, as expected, but at the same time, surprisingly the window that was closed *before* exiting Firefox, also opens again!


Expected results:

Only 1 window should open, and *not* any other windows that were purposely closed *before exiting Firefox* aswell.
