Hi there!

I have been having trouble with Firefox continuing to autoplay videos even with preferences set to "Block Audio and Video."

If I go to twitter.com or elsewhere Firefox will show that auto play is disabled, but videos will autoplay with no audio. I would just like to get this feature working as autoplaying videos are incredibly annoying!

Thanks for any help!

We need to access a web site of the European Medicines Agency where graphs are only visible if the Adobe Flash Player is running. This is no longer possible with FireFox 64 bits ... which forces us to use Edge (which we do not like)... Since EMA may take a lot of time to convert its web sites for using HTML 5 and stop using Adobe Flash Player, we do need an alternative for FireFox ... Is there any that Mozilla would recommend ?

Youtube videos stuttering after updating to firefox 72

After updating to firefox 72 (maybe it was after 72.0.1 - I did not have time to check so fast) videos on youtube started stuttering. When I start video everything seems fine but after a while it starts microstuttering - image is twitching, movement of camera is not fluent.

It looks like it is related to all videos on youtube. I watch mostly 1080p 60fps and these most often cause this issue. Example video: https://youtu.be/1La4QzGeaaQ It is easy to observe it at 1:27 with camera movement and terrain being fluent or not. If I pause video and resume play after few minutes it seems fine for minute but then it starts being choppy again. It does not seem to be related to video quality. I had 0 dropped frames in yt stats. I found workaround - if I set media.wmf.vp9.enabled to false and restart browser with this setting set to false everything is fine. But when I set it to true (like it always was for me) problem starts to occur. However no matter what I set youtube still shows "codecs: vp09". I do not have this problem on microsoft edge. I never had this problem on firefox 71 and I did not add any new extensions since few weeks. It must be new firefox fault, not my hardware or configuration.

For the last few days, every time I click on a Google Image I get the message:

Redirect Notice

The previous page is sending you to <the page I wanted to go to>
If you do not want to visit that page, you can return to the previous page.

This is fantastically annoying and appears to be limited to Firefox. Chrome doesn't do it, and I run both with a similar set of add-ons. I've seen suggestions to set accessibility.blockautorefresh to false in about:config. It is already set to false.

Hey everyone,

For some reason, when I try to print HTML documents from Firefox, it is only printing the first page. This is not affecting ALL webpages, but it is affecting MOST.

If I try printing the same HTML page from another browser, it prints all pages without difficulty. But in Firefox, the print preview screen will show 'page 1 of 2', and the second page will be blank.

Is there anything I can do to fix this?

PayPal checkout popup window loads indefinitely; cannot make a payment

When using the "Checkout with PayPal" button on websites the PayPal popup window appears however it's impossible to progress to the checkout.

When OneTouch is activated, the text 'Securely logging you in...' appears overlayed with the spinning wheel in the popup window. This continues indefinitely.

When this is not activated the window doesn't progress further after entering the email as prompted by the window and pressing Next.

It's possible to login to PayPal in a separate tab however that doesn't influence the popup behaviour.


Looking at the console in the popup there are a few 'Unable to find window by ref window.js:148:14' errors.

In the 'host' window where the popup was called from the console displays the 'Failed to execute ‘postMessage’ on ‘DOMWindow’: The target origin provided (‘https://www.paypal.com’) does not match the recipient window’s origin (‘https://www.paypal.com’).' error.


I believe this could be a recent issue because I was able to make several payments last month with all settings the same. I have a separate user.js file that I keep my settings in (I can send it over if required). These settings have not been changed since the file has been created.


The following actions have been tried and didn't improve the situation:

- refreshing the current profile

- disabling all addins

- adding paypal.com into exclusions for 'Block pop-up windows' and Enhanced Tracking Protection

- cleaning History and cookies


I then launched Firefox with a separate 'clean' profile and was able to make the payment successfully. Sure enough, importing my user.js file broke PayPal. I went through the settings commenting them out by groups.

The following setting was causing the issue:

user_pref("privacy.firstparty.isolate", true);

Setting it to 'false' made the PayPal popup window work correctly again.

Thought that this would be helpful for anyone experiencing similar issues. Cheers.

When I have my computer plugged into an external monitor, I want new browser windows to open on the external monitor, but they always open on the computer's monitor. I have gone through the entire process at https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems (clearing cache etc., trying safe mode, creating a new profile, refreshing Firefox, reinstalling Firefox) and the problem persists. This happens if I manually select "New Tab," "New Window," or "New Private Window" from the File menu with no existing windows open. It also happens if I use the key commands for any of these menu items. It happens if I use the menu bar on the computer's monitor or the menu bar on the external monitor. Opening a window and dragging it from the computer's monitor to the external monitor does not change anything. I've also tried using Divvy (https://mizage.com/divvy/) to move the browser window between windows with a key command, but after moving it this way nothing changes—new windows continue to open on the computer's monitor. How do I set which monitor Firefox will use for displaying new windows and/or get it to remember my preference?

System details:

MacBook Pro (15-inch, Late 2016) macOS Catalina, Version 10.15.2 Firefox 72.0.2 LG HDR 4K external monitor (Model 27UK850) CalDigit TS3 Plus Thunderbolt dock Computer connected to the dock with Thunderbolt 3 LG external monitor connected to the dock with DisplayPort 1.2

I am trying to access a site where the certificate doesn't match the site URL. I know it's okay and I want to accept the risk and continue. I click Accept the Risk and Continue, but it never works and instead I always return to the 403 error Forbidden page. I have tried clearing the history, cache & passwords (I don't use a password on this site), but that didn't work. Is there any type of Whitelisted Sites on Firefox? I have verified that this behavior happens outside the network I'm on, so it isn't being blocked by my site admin.

When I right click the back arrow button, the dropdown shows up to 5 or 6 FB login pages. They all have the same url but if I click on the first one it also creates multiple login pages. The only way I can get them to vanish is to clear my browsing history before I proceed with logging in to FB. Is this something FB is doing, or is it Firefox, or is it malware? I'm on a laptop. PC.

How to keep your YouTube Gmail login separate from your main Gmail login?

I have a main Google email account (for my important emails) and a secondary Google email account for YouTube with all my subscriptions etc. I'm not a creator. Until recently, I could open Gmail and see my main email account and I could go to YouTube and automatically be login with my YouTube Gmail account. I refreshed Firefox and now when I open YouTube it asks me to sign in, when I do it changes my login in Gmail, so I have to re-login to Gmail to my main email account. When I re-login to Gmail, it signs me out of YouTube into the other Gmail account! It goes back and forth wasting time. I would be grateful to fix this to save the wasted time it takes to keep having to login back and forth. I've been searching for an answer and haven't found a good solution yet. All I've found are frustrated people in various threads. My Android phone is able to keep my Gmail account logged in and my other Gmail account logged into Youtube but, on my mac computer on Firefox it no longer keeps them separate. It seems to have happened after I refreshed Firefox recently.

I look forward to hearing if there is a solution. Thank you.

When I try to attach a file to an email send in Gmail, nothing happens. The upload bar shows no progress and the email sits in the draft folder. The size of the file has no bearing on the problem. I've tried running in Safe Mode and even did a clean reinstall but it didn't help. The problem does not occur with the same accounts in Chrome or Opera; only in Firefox. I've tried everything recommended here, but nothing helped.
