Firefox 82 PDF Viewer skips matches when searching:

"When I open a pdf document in the Firefox pdf viewer, and I open the find bar to search for a phrase, the "next" and previous" arrows skip matches. "Next" takes you to match number 6, then match number 11, and so on. You get every fifth match. This is a real hassle with a very long document. How can I get it to work the usual way, and take you literally to the next match?"

Bug: Bookmarks toolbar for new tabs changes screen resolution for new window when privacy.resistFingerprinting is turned on
Status: NEW
Priority: P3
Created: 2020-11-17 14:08:22+00:00
Resolved: 2024-09-09 19:25:16+00:00

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:78.0) Gecko/20100101 Firefox/78.0

Steps to reproduce:

With the Bookmark menu enabled only for New Tabs (for me enabled per default in Nightly) the screen resolution changes when opening new windows.
I have privacy.resistFingerprinting on, so the nice 1000x1000 gets replaced by 1000x1020.


Actual results:

Screen resolution increases for new empty windows (new tab) and remains increased when opening a non empty site.
Screen resolution remains correct for new window with content (open link in new window.


Expected results:

At least with privacy.resistFingerprinting activated the screen resolution should not change.
I fixed this by disabling the bookmark menu for new tabs, so before enabling the new menu one could check for the privacy.resistFingerprinting property.

Steps to reproduce:

Attempt to create a book mark with search parameter inside the server address url
Background:
(moving from chrome, and this is a need to have)
My company has several development machines, they are named dev01, dev02, dev03 etc.

When trying to login to certain services on these dev machines, we have to enter a super long url, with postback junk and a whole bunch of parameters.
Pain in the but to do manually all the time.

We found though with google we could create custom search engines, these looked like:
url: http://dev%s.dev.com/
keyword: devservice

Then you would type "devservice 04" and you would go to dev04.dev.com

I found firefox bookmarks was the closest way to do this. However it does not allow the "%s" unless it is after a forward slash.

ReproSteps:
Attempt to create a bookmark url with the search parameter %s inside the address: ie: http:/dev%s.dev.com



Actual results:

save button is disabled


Expected results:

save button should be enabled

Resolution: INVALID
Created: 2020-11-18 09:48:36+00:00
Resolved: 2020-11-23 15:20:46+00:00

**Affected versions**
* latest Nightly 85.0a1
* Beta 84.0b2
* Release 83.0

**Affected platforms**
* macOS 10.15

**Steps to reproduce**
1. Launch Firefox.
2. Go to "about:config", and put the pref `browser.newtabpage.activity-stream.asrouter.devtoolsEnabled` on true.
3. In a new tab, click on the "Expand devtools" icon from the right upper corner.
4. Find "PIN_TAB_72" message, and click on the "Show" button.
5. From the URL bar, click on the "Recommendation".
6. Observe the animation inside the doorhanger.

**Expected result**
* A mouse pointer animation, with a pause button is displayed.

**Actual result**
* There is no animation displayed in the doorhanger.

- S3, since this only affects macOS 10.15.

**Regression range**
- It seems that the issue is not reproducible on 75.0a1 (Build ID 20200304161940), I'll try to look for a regression range asap.

**Additional notes**
* I was not able to reproduce the bug on other platforms than macOS 10.15, and it might be specific to certain mac machines. The issue appear to only occur on one macOS, from the ones tried, so please let me know if more info is needed here.

Bug: Firefox often stalls ALL connections when there is a slow connection from a tab
Status: RESOLVED
Priority: --
Resolution: INCOMPLETE
Created: 2020-11-18 10:36:42+00:00
Resolved: 2020-12-21 12:20:14+00:00

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.16; rv:82.0) Gecko/20100101 Firefox/82.0

Steps to reproduce:

Browse as usual
Click a link to open in new tab or Open a new tab and quickly type and go to a URL


Actual results:

The new tab's connection is stalled, no indication of anything, just waits as if it's loading.

Opening any subsequent tabs, clicking on links in other tabs, etc., results in the same behavior. 

After an indeterminate amount of time - from a couple seconds up to 30+ seconds - the issue resolves and all the connections go through immediately. 

While the issue is happening, I don't see any network connectivity issues. Other browsers (Safari, Chrome, Wget, Curl) have no issues connecting to the corresponding URLs. No abnormalities in traffic can be seen.

What I noticed is that it usually happens if I have a site that has slow-resolving connections (i.e. very high TTFB) open in Firefox. No matter if it was the active tab or not, it just has to be running in the background and making AJAX requests.

This has been happening for a few months now over different FF versions and unfortunately I don't have a good way to reproduce it. The best way I can describe the feeling of the issue is as if the connections in FF are sequential and one slow connection can stall all subsequent connections. 


Expected results:

The new connection is made and the URL is opened quickly as usual.
Bug: Google Meet zooms in presentation randomly
Status: RESOLVED

Resolution: DUPLICATE

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:83.0) Gecko/20100101 Firefox/83.0

Steps to reproduce:

Open a Google Meet meeting in Mozilla Firefox version 83.
Open the same meeting from another account and share your screen.
Pin the presentation from the first account



Actual results:

After some time the presentation will be zoomed in the upper left part of the presenter's screen. This can be fixed by clicking on the 3 dots and going to settings -> video and switching receiving quality to Audio only and back into the original setting but this is a temporary solution.


Expected results:

The presentation should not be zoomed in.
