Bug: about:restartrequired should not say "we will restore all your pages" as all private windows will get lost after restarting

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:82.0) Gecko/20100101 Firefox/82.0

Steps to reproduce:

I was planning my trip in incognito mod to get the best deals. I had 10+ pages with different reservations. Then it stopped to open new tabs. Instead it opened the firefox page "Restart required". There is the line  "We will restore all your pages ... so you can be on your way quickly"  . I was a little bit inattentive that I was in the incognito mod so I restarted the browser and lost all my data.


Actual results:

I lost all my incognito tabs(
It's a defect because the "Restart required" page confuse users with "We will restore all your pages ... so you can be on your way quickly" 


Expected results:

1. (Optimistic) Don't require restart if incognito tabs are open.
2. (Realistic) Fix message. Add big red text that all data from incognito tabs will be lost . It can be showed only when incognito tabs present. [It's important that this message appears if user currently in the normal mod but have incognito tabs in the background]

Firefox 84.0a1

A frequently visited subdomain `abc.example.org` is the default action for pressing Enter ('Visit') label when I enter `example.org`. For a completely entered domain, the default action shouldn't be a subdomain

Steps to reproduce:
1. https://developer.mozilla.org/ often (no idea how often is needed)
2. Enter `mozilla.org` into the address bar.

Expected: mozilla.org should be in the first row with a 'Visit' label.
Actual: developer.mozilla.org as default action.

Workaround: Press Esc key.

##### [Suggested Severity:]
S4

##### [Description:]
Trying to move the first unpinned topsite over a sponsored tile will create an empty placeholder. 

##### [Environment:]
Windows 10, Mac OSX 10.15
83.0b10-trybuild

##### [Preconditions:]
Position 1 and Position 2 have sponsored top sites.

##### [Steps:]
1. Download and install RO localized Firefox.
2. Create an user.js and set: browser.topsites.useRemoteSetting = true and browser.search.region to "RO", connecting to the staging main-preview.
3. Start the browser with the predefined profile.
4. Open a new about:preferences#home and set topsites to be shown on 4 rows.
5. Open a new tab.
6. Observe the topsites section.
7. Drag the third topsite over the first one (sponsored)

##### [Actual Result:]
- An empty placeholder is created on the third position. 
- If any other topsite is moved over the first position (over a sponsored tile), it will first be placed on the first unlocked position (3rd position in this scenario) and redoing the operation will create the empty placeholder.

##### [Expected Result:]
The topsite is placed back to its initial position (3rd in this case). There are no empty placeholders created.

##### [Suggested Severity:]
S3

##### [Description:]
Toggling pin/unpin context menu on a sponsored topsite would modify other tiles positions. This can be reproduced on a clean profile easily by pinning a topsite with some empty spaces between as shown in the actual result [recording](https://drive.google.com/file/d/1AmA5xjD_R2Xt4wK1AqEE4qOcOR8gqOqF/view?usp=sharing) , but can be reproduced on frecency rich profile as well.

##### [Environment:]
Windows 10
83.0b10-trybuild

##### [Preconditions:]
There are sponsored tiles listed in the topsites.

##### [Steps:]
1. Download and install RO localized Firefox.
2. Create an user.js and set: browser.topsites.useRemoteSetting = true and browser.search.region to "RO", connecting to the staging main-preview.
3. Start the browser with the predefined profile.
4. Open a new tab.
5. Pick any sponsored topsite and choose to pin it using the menu.

##### [Actual Result:]
Different pinned tile changes position.
(see [screen-cast](https://drive.google.com/file/d/1AmA5xjD_R2Xt4wK1AqEE4qOcOR8gqOqF/view?usp=sharing))

Bug: Downloaded files get the extension dms

Created: 2020-11-09 19:31:34+00:00
Resolved: 2020-11-13 19:14:01+00:00

Recently when I've been downloading files from sites that are delivered as application/octet-stream with no Content-Disposition the file has been getting named with a dms extension which is not correct.

I saw this downloading Snapcamera (https://snapcamera.snapchat.com/download/). The url downloaded (it expires so probably doesn't work now) is `https://storage.googleapis.com/prod-studio3d-binaries/binaries/582bdb3b-f1f8-4b79-b8dc-be446f0f4741/Snap%20Camera%201.10.0.pkg?GoogleAccessId=968296265399-compute@developer.gserviceaccount.com&Expires=1604948882&Signature=clipped` and Nightly chose to save the file as `Snap Camera 1.10.0.dms`. Firefox release gives it the correct filename: `Snap Camera 1.10.0.pkg`.

Mozregression points to bug 1667787 as the culprit.
Bug: urlbar.tips.tabtosearch_onboard-shown overcounts impressions

`urlbar.tips.tabtosearch_onboard-shown` is counted every time `UrlbarProviderTabToSearch` [sends an onboarding result to the muxer](https://searchfox.org/mozilla-central/rev/919f7400e2e12bc963ee2ae8400ef961972c3059/browser/components/urlbar/UrlbarProviderTabToSearch.jsm#289,292). This is wrong in two ways:
1. The probe is incremented on every keystroke rather than just once when the search engine domain is autofilled (see bug 1675611), and
2. The probe is incremented when the user's typed query partially matches a search engine domain, but it is not autofilled. For example, searching for "a" matches "amazon.com", but if the user's profile doesn't autofill "amazon.com", the onboarding result is not shown but the probe is incremented.

Bug: Image upload fails with corrupted upload in various websites
Status: RESOLVED
Priority: --
Resolution: INCOMPLETE
Created: 2020-11-10 08:53:35+00:00
Resolved: 2020-12-10 08:37:33+00:00

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:78.0) Gecko/20100101 Firefox/78.0

Steps to reproduce:

Upload bug exists on (at least 3) websites: www.werkspot.nl, www.marktplaats.nl and www.sinterklaasjournaal.nl . The latter is the easiest to test since it doesn't require an account.

Click the top right "Stuur je tekening naar de burgemeester van Zwalk"
Enter name
Upload photo


Actual results:


Observe the uploaded image is garbled.

Same happens when uploading images to the other two websites mentioned.


Expected results:

Should have uploaded the image correctly and showed the correct preview.

Note, the original image format makes no difference (png, jpg, all fail). 
Restarting in Safe Mode makes no difference, disabling tracking protection makes no difference.

Works fine in Chrome / Edge.

Does not appear to be a Sandbox issue since I restarted Firefox with Full Disk Access enabled (as a test).

Playing smooth as did on 80.0 and older versions..
Bug: Shut up "Ignore PDF.js for this download." errors from the PDF stream converter
Status: NEW
Priority: --

After bug 1633270, we log to the console for every application/octet-stream download that we consider using pdf.js for. We should change the setup here so that failure to use pdf.js (because it's not a PDF!) doesn't create console errors. IIRC this may not be trivial because the exception is the way we indicate to the caller that we don't want the stream, and IIRC xpconnect forces logging JS exceptions when called from C++. I could be wrong though...
