Bug: TranslationsParent.isSupportedAsToLang checks the wrong language
Status: RESOLVED
Priority: P3

### Description

When testing the localized versions of the SelectTranslationsPanel, I noticed that languages for which we only offer translations as a source language were being offered as a target language. At the time of writing, this occurred with Finnish, which we currently only support as a source language. 

This leads to an error state when the panel opens, since Finnish cannot be found as a valid target language (see attached screenshot).

This is caused by an unfortunate typo that I made, where the [isSupportedAsToLang()](https://searchfox.org/mozilla-central/rev/1f46481d6c16f27c989e72b898fd1fddce9f445f/toolkit/components/translations/actors/TranslationsParent.sys.mjs#2227-2240) function checks the `fromLang` value instead of the `toLang` value. 

Thankfully, the SelectTranslationsPanel is currently the only consumer of this function call, and this fix should not require any uplifting because it will be corrected before the SelectTranslationsPanel release. 

---

### Steps to reproduce

1) Download the Finnish version of [Firefox Nightly](https://www.mozilla.org/en-US/firefox/all/#product-desktop-nightly).
2) Open the Finnish nightly and navigate to a non-Finnish page in a translatable language, e.g. https://es.wikipedia.org.
3) Select some text and open the right-click context menu.

**Expected Behavior**
Translation to Finnish should **not be offered** as it is not yet supported as a target language.

**Actual Behavior**
Translation to Finnish is offered, and when clicked, it leads to a panel error state with a blank to-language selection.

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:126.0) Gecko/20100101 Firefox/126.0

Steps to reproduce:

I was cleaning up my desktop (no uninstalls, just re-arranging icons) and un-pinned firefox from my taskbar.


Actual results:

When I went to launch Firefox from the  Start panel, I couldn't find it. It was completely gone from my computer. It wasn't listed in "apps" and after doing a quick search on C:\, I wasn't able to find "firefox" or "mozilla" anywhere.  


Expected results:

My fix was to re-install it (so far so good), but all it all it was really strange and I figured this might be of interest to you folks. A Microsoft "glitch" or whatever...

Actual results:

The cursor remains unchanged, the tab doesn't respond or move in any way. It can't be detached to a new window or reordered with the other tabs.


Expected results:

Normally the cursor becomes a closed fist and a small thumbnail of the tab's contents float by the cursor when it's dragged away from the browser to open in a new window, or it can be shuffled around the other tabs.
Bug: Downloading Blank Files and Uploaded the Correct File With “(1)” After It

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:126.0) Gecko/20100101 Firefox/126.0

Steps to reproduce:

I downloaded a file (png, jpg, mp4, etc.).


Actual results:

At the requested location, two files are downloaded. One is a blank with the correct name of the file I wanted. The second is the file itself but renamed with "(1)" at the end.

As an example, I want to download "FILE.png", but instead, I get a blank file named "FILE.png" and the correct file renamed "FILE(1).png".

This doesn't happen with every download. I don't know how to recreate it. It just happens at random. I suspect it has something to do with the cache because the issue seems to stop after I clear it.


Expected results:

I want to download the file I want with the file name I want. I don't want a blank file or a renamed file.

When using the "Restore previous session" feature in Firefox, all open tabs are lost if the normal browsing window is closed before the private browsing window. This results in the loss of all open tabs and sessions, which can be highly disruptive to user workflows.

Steps to Reproduce:
    1. Open Firefox in normal browsing mode.
    2. Open a new private browsing window.
    3. Close the normal browsing window while keeping the private browsing window open.
    4. Close the private browsing window.
    5. Reopen Firefox in normal browsing mode.

Expected Result:
Firefox should restore the previously open tabs and session in the normal browsing window.

Actual Result:
Firefox does not restore the previously open tabs and session. All tabs are lost, and Firefox opens with a blank or default new tab page.
Bug: Addon bar and tabs bar freezing
Status: RESOLVED

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:126.0) Gecko/20100101 Firefox/126.0

Steps to reproduce:

I was talking with Chat GPT. I wanted to take a high-quality screenshot, so I zoomed in like 250% or 300% with scroll, and a while later tried to click the size button next to the site address (little box with percentage) to go back to the default 100%. It didn't let me, it was stuck. Also, I couldn't close the current tab and couldn't click any addons. Switching tabs from third one (current) to the first one (empty site) resolved the problem.
I don't know if it's random or reproducable. It may have something to do with Chat GPT, but that's just my guess.
I am not using any overlays.
I do have enough RAM (32GB) and my PC is really capable of handling the browser.
I am using fullscreen 1440p (2560 x 1440)


Actual results:

My addon bar and tabs bar freeze, and I can't click anything. It's not like it's not responding, but more like it's locked by something else. When I'm navigating through tabs, I can't close the current one, often can't close tabs next to current, but I can click like 3 tabs further, and it suddenly unfreezes.


Expected results:

I should be able to close tabs, and use addons. Freezing, or locking, prevents that.
Bug: Firefox going back pages until new tab.

Steps to reproduce:

Seems to happen quite randomly, often without any key input at all.



Actual results:

Firefox starts to go back my tabs page history until reaching the new tab menu. Changing tabs affects the new tab as well. Continues until restarting firefox.


Expected results:

Nothing, quite literally.

**Found in**
* Firefox 127.0b3

**Affected versions**
* Firefox 127.0b3
* Nightly 128.0a1

**Tested platforms**
* Affected platforms: macOS 14. Ubuntu 22.04, Windows 10

**Preconditions**
* Ensure that the "Always ask you where to save files" option is enabled in about:preferences.

**Steps to reproduce**
1. Navigate to [CNN](https://edition.cnn.com/2024/05/19/style/isabella-gardner-heist-facts/index.html).
2. Enable Screenshots using Ctrl+Shift+S.
3. Take a screenshot and select a location to save it.
4. Observe the filename of the saved screenshot.

**Expected result**
* The filename should follow the pattern: "Screenshot YYYY-MM-DD at hh-mm-ss website title".

**Actual result**
* The title of the website in the filename is truncated with an ellipsis. Example: Screenshot 2024-05-20 at 10-39-16 Five things you proba[...].png.

**Regression range**
* This issue seems to be a regression, as it does not occur in Firefox 126 with screenshots.browser.component.enabled set to true.  I'll look for the regression range ASAP.

Both `browser.newtabpage.activity-stream.system.showWeather` and `browser.newtabpage.activity-stream.showWeather` are set to `true`.

The widget doesn't appear at all on the New Tab page; the page looks identical in both configurations.

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:125.0) Gecko/20100101 Firefox/125.0

Steps to reproduce:

Over a year ago I presented this bug already, but nothing happened since. Therefor I present here a few screenshots to show clearly what the issue is.
What I do: I use a Firefox theme to decorate the upper part of Firefox.


Actual results:

 When I use and apply a Firefox theme such as Iridescence Dark or other, the window bar in Firefox disappears and Windows buttons are displayed instead of my Mac buttons (I use a MacOs Layout).


Expected results:

Applying a Firefox theme should keep the window bar and should display the chosen Mac buttons. This is the case e.g. in Firedragon and in the latest version of Linux Mint. See the screenshots below that I've attached here. It is only possible to present a screenshot, but I have 4 screenshots to show you all steps of this issue. So I'll make several bug reports that I deliver to you. You should make it possible in the future to post several screenshots for ONE bug report.
In the first screenshot below you see Firedragon with window bar, when I apply a Firefox theme with Mac buttons.
