Bug: pdf.js occasionally shows incorrect symbols until page is refreshed
Status: RESOLVED
Priority: P1
Resolution: FIXED

Resolved: 2020-05-20 12:25:15+00:00

I don't have easy steps to reliably reproduce this but I probably see it on average after about 2-3 hours of PDF reading.  The issue is that some symbols (I believe it is "some fonts") display incorrectly in the document I'm reading.  Reloading the page immediately fixes the symbols.  I've attached a screen shot of a page, before and after reloading the page.  Check, for example, the second line, where Prt(A) was incorrectly rendered as \eta\phi(A).  Some potentially useful points (I haven't confirmed if they are important):

1. I am reading this document from a file on my hard drive, not the web.
2. The document in the images is freely available here [1].
3. I am currently on the 01-05-20 nightly build on Windows.
4. I read a lot of PDFs.  I'd say that this popped up, roughly, sometime in the last month.
5. I have gfx.canvas.remote set to true.  I don't know if this still on in nightly by default or not.  This is part of Bob Owen's project to move 2D canvas operations out of the content process.  I set that to true many months ago but, again, just recently started seeing this.
6. Reloading the page seems to fix it every time.  Other things, like changing tabs or switching window focus, seem to have no effect on the bug.
7. I haven't seen the issue when just opening a document, but this may be a coincidence.  I have always come across it after scrolling through the document.

Actual results:

License texts are missing from about:license.


Expected results:

The license texts should be visible on the about:license page.

Bug: Nightly new tab takes a long time to load, then tries to download website

Hello! I use Firefox Nightly on Mac OS (I see version 73.0a1 in about:support).

Today I noticed a new problem:
- Nightly is occasionally taking very long to load a website in a new tab.
- It's not a network problem -- I switched WiFis to test, and other borwsers are able to load the same website acceptably fast.
- Then sometimes after a while, I see a download prompt, like if Nightly is trying to download the website for some reason

(Note: The URL I tried was https://github.com/gitpod-io/website, which is why the file is called "website".)

Actual results:

While having browser.messaging-system.whatsNewPanel.enabled set to false and done the update from version 71 to version 72 the gift icon appeared after around 5-10 minutes on the right to the address bar. Resetting browser.messaging-system.whatsNewPanel.enabled in about:config and setting it back to false again caused the gift icon to immediately disappear but after a restart of Firefox and waiting for around 5-10 minutes again the gift icon just appeared again.


Expected results:

With browser.messaging-system.whatsNewPanel.enabled set to false the gift icon should never appear on the right to the address bar.

Click on the blue area with the middle mouse button and try to scroll a bit.
Terminate scrolling by clicking with the middle mouse button in the blue area again.
This behaviour was noticed with the embedded svg flowcharts contained in https://www.onkopedia-guidelines.info/en/onkopedia/guidelines/chronic-lymphocytic-leukemia-cll/@@guideline/html/index.html


Actual results:

The scrolling behaviour becomes uncontrollable now. By just moving your mouse up and down, the page scrolls. Using the scroll bar will make the page scroll by itself back to the starting position. This behaviour can only be stopped by reloading the page.


Expected results:

Scrolling should stop after the second middle mouse click.

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:71.0) Gecko/20100101 Firefox/71.0

Steps to reproduce:

1.  Configure the ExtensionSettings policiy by way of the policies.json file in the C:\Program Files\Mozilla Firefox\distribution\ folder so that all extensions are blocked by default.

    "ExtensionSettings": {

2.  Open about:addons and attempt to install an extension such Facebook Container.


Actual results:

Error message "Firefox prevented this site from asking you to install software on your computer." received.  The installation was blocked, but our custom message was not displayed to alert the employee who blocked the installation and why.


Expected results:

Error message should have been the custom one that was specified in the policy.  If attempting the installation from https://addons.mozilla.org/en-US/firefox/addon/facebook-container/?src=search, I receive the message I was expecting.

"Facebook Container (@contain-facebook) is blocked by your system administrator.  Custom Message Still Needs to Go Here...".

Steps to reproduce:

Just start Firefox, restore bookmarks from JSON file (because they're corrupted), wait a while (<1hr) and bookmarks corrupted again.

By corrupted, I mean that they aren't what there were restored as - some entries are OK, some are missing. It's as if the bookmarks are being restored from a file/database somewhere.


Actual results:

See above


Expected results:

Bookmarks unchanged
