Firefox Support Forum

Hello,

I have been unable to watch Netflix or any "other" video content using the Firefox browser for the past few weeks. I've been pulling my hair out while working through the help articles, alongside bouts of furious googling - all to no avail.

On Netflix I am getting error code F7701- 1003. Netflix is telling me to use the latest version of Firefox, but I have been checking for new updates almost every day since I noticed this issue. My current version is 100.0 (64-bit) On other website I'm getting the error message "No compatible source was found for this media."

I have followed all of the fixes listed on the following articles, but so far have not been able to fix my problem: Fix common audio and video issues Fix video and audio problems on Firefox for Windows N editions

If there is anything I haven't tried yet, please let me know.

Just recently I am having trouble viewing videos of any kind, in Facebook, or u tube videos, Firefox has worked perfectly until a couple of days ago, I don't know what has changed

I need to turn off my Delete cookies and site data when Firefox is closed setting.I have wrongly turn on this setting i need to turn off this setting.please help me to change it.

I have just installed V.100 and have come across a small problem. I can't sign into 'The Canberra Times' site. The option to sign in is missing from their home page. It is there using MS Edge or Chrome and I can login to the site on those two browsers. This does not seem to be a problem with other websites that I have tried since the new version!

I can't even begin to imagine what might be going on with a situation like this! Thanks.

I have spent hours trying to unblock a site i have previously used before your upgrade. every time its a nightmare. Why can't your program remember exceptions. I tried all the exception options. I tried adding the certificate exception and was told it was valid and did not need an exception. Why does everyone feel the need to make our lives harder with the illusion you are protecting us. Make it easier to go to websites that we want to go to and not a hassle every time you decide to change something. Website is https://www.btdig.com/. Thanks for your time.

how can I restore to white, the black background on the Firefox Browser, even my menus have turned black. I have tried through my normal settings and although it states I have a white background. It doesn't

Hi folks, I've been searching but haven't found anything, the Twitter Twists aren't showing on my home page. They are displayed on all other browsers such as Chrome or Opera, here is the link. https://borderline-selbsthilfe.org Thank you Greetings Alaska

After updating Firefox, I now have a horizontal line across the upper portion of my computer screen. I have uninstalled FF and updated again thinking it would remove it. I have searched for a resolution and nothing has worked for me. I don't want to have to pay an expert to remove the line. Please give me a fix for this as it is really bothersome.

I've recently made the switch to Firefox coming from Opera, and there's a few behaviours I'm missing / haven't figured out how to set up to match what I'm used to. Could someone point me in the right direction?

1) When I click an external link (e.g. in Discord) to open in browser (Firefox is now default), it opens the link but it overrides the currently selected tab rather than opening a new tab.

2) Following on from that, clicking the link also doesn't make Firefox the active window. Previously if I opened a new link from elsewhere, the other browser would come to the front. Can Firefox do that too?

I currently have it set so that opening a link in a new tab doesn't switch to that tab. Which is behaviour I want (if I'm doing that in Firefox itself).

Having any google related webpage open for more than a couple of minutes causes it to disconnect (gmail, calendar). This results in no connectivity to any Google services. Opening new tabs will refuse to load even Google.com. The only fix is to completely close out of Firefox and relaunch. But having gmail open for a few minutes will result in it disconnecting again.

The issue persists in 'troubleshooting mode' as well as after doing a refresh. I have experienced this now for the past couple of weeks on my Windows 10 work laptop. I have also seen this on 2 different Linux machines in the past few days. I had attempted to disable http3 and telemetry settings from an older post I had found, but no luck. Not sure what else to try at this point.

On the page: https://support.mozilla.org/en-US/kb/manage-downloads-preferences-using-downloads-menu#w_downloads-panel-automatically-opens it says: "Downloads panel automatically opens" "Every time you start a download, Firefox will automatically bring up the Downloads panel by default, . . . "

It never used to do that ! Having the Downloads panel drop down and just sit there covering a large part of the page every time I save a little picture is an extreme nuisance ! How do I prevent it from happening ? Please help ! Many thanks !

I've downloaded your new version"100" a few times and have found the same problem as a few others. I've tried re-installing a few times, and even after completely un-installing older versions, including clearing cache data etc., but the same thing happens. Are there a few 'bugs' to fix in the new "100" version or is another browser sabotaging this version in some way? I didn't have problems with earlier versions.

Hello, I have trouble with browsing Facebook, sometimes there is a huge memory leak (please check the first uploaded image), and as you can see in the second uploaded image, after I "end task" the Firefox tab that use a lots of memory, the Facebook tab crashed. The third uploaded image is the addons I have installed.

Is there a way to solve this? I go to about:memory and click on all there buttons in "Free memory" but that seems to have no effects.

Thank you for your time, Tom.

Hello dear volunteers (followers),

After Firefox Update to 100.0, the Theme that I created (JOHN - Light Grey) stopped working properly. More Specific all drop-down and pull-down menus have been transformed to a "white" background color, overcoming the initial created one, which was "dark gray".

So I tried to revise (update) my "Theme". But this became impossible.

In Developer Hub, in Theme Generator there was a (pink) frame warning "the following manifest properties that your most recent version upload used in it's manifest are unsupported in this wizard and will be ignored: properties popup popup_text tab_loading So I couldn't edit the theme and even more I can't finish and save any changes. Well, Is there any skilled user to give me a hand ? I would appreciate too much any piece of advice ...

Herewith I attache relevant screenshots.

Thank you in advanced

Hi, I cant log in to any plusnet pages, this is not just Firefox other browsers do the same. I get a message Secure connection failed. All other websites seem ok. Even private browsing is OK but no PLUSNET. I use Firefox 100 and search with Duck Duck Go. Please help as Plusnet can't. Many thanks I.M.

I have one website, newsleader.com, that says I need to enable Javascript for it to work. It worked yesterday and I didn't change anything. I have done all suggestions to enable Javascript and it shows that it is enabled. This site works fine on Chrome. Thanks
