User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:74.0) Gecko/20100101 Firefox/74.0

Steps to reproduce:

1. Go to YouTube
2. Go into search bar
3. Search for something
4. See how the input lags


Actual results:

Since a few days ago I experience lag while typing in the search bar of youtube. I type something like for example "minecraft" the first one or two letters apear and after like 5 sec or so the other letters appear. While it lags, I can't do anything with that tab. (The entire tab freezes but I can still switch tabs normaly.)

This only happens with youtube so far and only with firefox brower. Testet it with edge and there everything works as expected.

Add-on: "UBlock Origin" and "Watch2Gether Extension"


Expected results:

No lag, instant input.

Bug: Flash and DRM sites (mouse freezes, 3D broken,  pausing during "commercials"
Status: RESOLVED
Priority: --
Resolution: WORKSFORME
Created: 2020-03-14 05:25:25+00:00
Resolved: 2021-01-05 07:24:49+00:00

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:68.0) Gecko/20100101 Firefox/68.0

Steps to reproduce:

Flash 32.0.0.330 and prior versions.  Three MAJOR issues.

Any TV site in the US will probably be a problem.  Let's take this one:  https://www.nbc.com/the-six-million-dollar-man/video/the-moon-and-the-desert-part-2/375804732.0.0.330

You need DRM enabled, libavcodec installed, enable obsolete formats.  My internet is provisioned at 6 mb/s download and I never reach that.

So basically when trying to watch the movie and especially if there is a commercial segment, the video will pause with an off/on period of about 16s and play for 2s  until the commercials are over with the circular "wait" displayed on the screen.  the stop/play controls  are messed up too.  it does it with every commercial.  this makes a show very annoying to watch.

Occaisionally, the Synaptic trackpad on a Toshiba A665 laptop will freeze requiring a restart.    I reported this problem a long time ago and it was fixed, Now it appears to be back.  

Preliminary tests suggest that if the mouse is permanently placed off the screen like the right top corner a freeze won;t occur.  Moves are not watched in full screen,

3D (ADULT CONTENT) You do need a credit card to register to verify age, but don;t need to pay.  Goto Classic mode,  Log in.  There is a Virtual reality link link on the left.  Click that.  Pick a movie and select FREE PREVIEW.

To the right of the play VR movie, there is a gear. Click it and set the glasses mode and I tried a low bit rate.  I used to, a long time ago get a blurry picture without the glasses on.  Now nothing.  No modes work.

3D test Videos without DRM content play fine.

At some pint in the past, it used to work.

of course all you get is nothing.  More like a silent blue screen of death.

Most errors with video anywhere just suck.  Why can't Acrobat say.  The video is unplayable because the MIME type is whatever and FF is unable to play this video.

Usually some info is available with the debug console, but DRM may mess that up too.

There are way too many sites Still using Flash.  When you add DRM to the mix, it doesn't work any more.

Basically I can watch all the Youtube I want.  Forget any site using DRM.

of course the support basically says we don't support Linux.
Bug: Firefox v 74.0 crashes when running tests using selenium + teaspoon + jasmine + babylonJS
Status: RESOLVED
Priority: --
Resolution: INCOMPLETE
Created: 2020-03-14 10:29:52+00:00
Resolved: 2020-05-28 11:23:53+00:00

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:74.0) Gecko/20100101 Firefox/74.0

Steps to reproduce:

We have a rails gem with around 10 tests files(javascript), which use a library called [babylonJS](https://www.babylonjs.com/). They're written using jasmineJS v 2.3.4 which comes from another tool we're using called [teaspoon](https://github.com/jejacks0n/teaspoon) and we also used a firefox driver for selenium, with which we ran our automated tests.


Actual results:

If we run the test files separately they all work fine, but when we try to run them all together, they start producing errors and the browser crashes. This only started happening now, from v 74.0 of firefox.


Expected results:

We expected to be able to run them together without them crashing or failing, since they work completely fine on other browsers. We've currently moved to using a chrome driver for selenium so our builds could pass but we would very much like to be able to run them with a firefox driver as well.

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:76.0) Gecko/20100101 Firefox/76.0

Steps to reproduce:

There're two Windows 10 OS accounts in the system. One is a local non-privileged user with empty password and another is an admin user with MS online account login. When clicking on eye icon or "copy" button to see/copy saved password in about:logins a Windows security window with "Verify your identity to reveal the saved password" message pops up.


Actual results:

While under non-privileged system user:
Empty password for non-privileged system user is declined, security window pops up again.
E-mail and password identities for admin system user is also declined, security window pops up again.

While under admin system user:
Identities for admin system user is correctly accepted, saved password is shown.
Empty password for non-privileged system user is declined, security window pops up again.


Expected results:

Security window must accept empty user password or shouldn't pop up at all if system user password is empty.

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:74.0) Gecko/20100101 Firefox/74.0

Steps to reproduce:

On a forum a user posted an image hosted on a facebook page (https://scontent-amt2-1.xx.fbcdn.net/...) but this did not load because maybe my privacy badger, facebook-container or whatever plugin broke this.

I right clicked view image and this opened in the facebook container and therefore I could no longer return to the previous webpage.


Actual results:

I right-clicked view image
The image showed in the same tab
The same tab became a facebook-container tab
I decided the image was not nice and wanted to click to the previous page
The previous page was not possible to click (button was grayed out)


Expected results:

When I tried to click back for the previous web page it should have returned to the previous web page as happens with other images not from facebook.

Bug: Videos on new tabs take exactly 2 seconds to play back audio.

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:74.0) Gecko/20100101 Firefox/74.0

Steps to reproduce:

When I open a new video tab on Youtube (overwhelmingly I middle-click from gmail subscription notifications) and press the spacebar / click the videoframe / press the 'play' icon, the video will be muted for the exact first 2 seconds. This behaviour has also been found on Facebook newsfeed videos, and on ONE page/article of the Washington Post BOTH videos within had this issue (embedded youtube videos, if this matters).

This does not occur all the time -- I have yet to understand the pattern -- but it seems that if I've played a video recently, audio on a new tab starts just fine. But out of the top of my head, it is not evenly so. 

I get around this nuisance by waiting 2-3 seconds and then pressing 'zero' on the its number key, which resets playback to 0% of playtime, or just press 'leftarrow' to go back 5 seconds. Furthermore, resuming a paused video -- no matter how long it has been paused -- does not appear to have this problem.

This is a new Win10x64 install (about a month old), and the problem was present when I first installed Firefox (either v73.0 or v73.0.1); the issue carried over when it auto-updated to v74.0.0. Autoplay is set to "block audio and video". I do not find this problem in any other programmes (VLC, foobar, etc).

This is also not an issue with my speakers: after they've been inactive for a while, they'll go into some sort of standby, and when sound is played again, they "pop" back to life; I've turned them on just before playback, or used another application with sound just before, and the video still skipped the 2 seconds.



Expected results:

Audio should just play from 0m0s.

Was trying to debug bug 1528265.
I have a local page that will autoplay a flac page.

playback doesn't start and in the console you see:
NotAllowedError: The play method is not allowed by the user agent or the platform in the current context, possibly because the user denied permission.

Attempting to modify the autoplay permission by selecting "Permissions -> Autoplay : Allow Audio and Video" in the URL bar has no effect. Autoplay is always blocked for local file.

This is probably a toolkit bug, but wasn't sure.
