So the problem is that Firefox doesn't play any HTML5 content. Weirdly except for Youtube. Youtube works just fine. But every other Website shows errors. Even songsterr.com. I'm using latest Firefox 76.0.1 on a recent Ubuntu 20. 04 LTS installation. Usual troubleshooting like updates doesnt work because "sudo apt-get upgrade" doesn't find any updates. I tried the same websites in the latest version of Chromium and they work perfectly fine. I couldn't find a mistake in the firefox settings or something so I'm confused. Disabling Plugins didn't change anything and turning of tracking protection didn't either. What is the Problem here and how can I solve it?

One feature at www.weather.com (Weather Channel) is their "weather in motion" feature which loads interactive weather radars. For some reason, this is not working on my Firefox browser. It works fine in Chrome and Edge. The weather.com website loads just fine but the radar data (overlay on a map) will not load. IT WORKS FINE IN SAFE MODE. So i tried to disable all of my plug-in's, extensions and hardware acceleration in Firefox in regular mode. Still doesn't work. I created a new profile. Still doesn't work. I disabled the tracker feature in Firefox on that web page. Still doesn't work. I uninstalled and reinstalled Adobe Flash. Still doesn't work. Any ideas???

Hi.

I love Firefox specifically because it lets me use Ctrl+Shift+N, i.e. reopen a closed window. I have this one window with several pinned tabs (Facebook etc.) and a few other open tabs (some reseach, YouTube etc.) where I keep things that I need to return to. I essentially NEVER close this window without reopening it, because it has the most important things I need. Sometimes I open a second/third window to work in (I had an online exam the other day, so I opened that and my materials in a separate window, so I can cycle through them more easily).

When I open this second window, sometimes I close my main window (it has quite a few tabs so it slows Firefox down). I then always reopen it using Ctrl+Shift+N and never had a problem. Well, I closed it now (then opened one or two other new windows), but when I wanted to reopen my main window back up, it just refused to. It's gone from "recently closed windows". Interestingly enough, at least two other windows I closed BEFORE it (one from yesterday, that I did unrelated googling in; the other was closed a couple minutes before the main window, it was an emoticon set that pops up from one forum) were possible to reopen, but not my main window. Now I can reopen just 3 windows, and I don't understand where they are (there used to be up to ~10 or so).

I want to know why I was able to reopen windows I closed long ago, but not the most recent one, and whether there is a way to fix this and get the main window back. I have effectively lost ~40 tabs that I had open (some research articles, pinned social media, some stuff I wanted to read etc.) that I can't even reopen unless I find them through my History (and hoo boy, that'd take a while).

Thanks for any info. Have a nice day.


SOLVED - EDIT: The amount of windows that can be reopened can be fixed as mentioned below. Lost window probably cannot be restored, sadly. EDIT 2: Actually it can be restored! See the answer to find out how. Both these lovely people gave me answers to my questions, kudos to both of them.

Nationwide has decided recently that my firefox is not up to date and got me to delete bookmarks, then delete the cache. and some thing to do with the browser. I may have to ask them again as I have deleted bookmarks and updated but they still don't accept me or say there is a problem. any idea what I need to do with my browser? Things have worked well for years but no more. And being put back to my tortuous login every time is driving me mental. Best regards, Don.

I refreshed my browser, and after refreshing it, my passwords and log-ins were NOT imported, and I can't even save the log in information manually. Never had this issue before, and I don't understand what I need to do. I have the "Old Firefox Data" on my desktop, but am totally confused about how to get that information into the refreshed browser. Not being able to re-enter the info, clicking "save", works. Help!

Hi, Since yesterday Firefox won't play any live video streams on any website. An HTML5 error message shows up.

I've tried upgrading Firefox, disabling Add ons, starting in safe mode, completely uninstalling and starting from scratch and installing and deleting Adobe flash as a last resort.

I made sure everything was up to date on my laptop and they play no problem on other browsers. I just can't work out what's wrong with Firefox.

My Firefox for MAC 78.4.0esr (64-bit) Browser Window shakes horizontally, uncontrollably, when I click on links in websites. This began just before the last update, and happens more frequently than not, forcing me to abandon the application because I can't close the shaking window. I can't see a specific pattern to which links will cause this to happen, but if I restart Firefox and try the same link, it will repeat the error. My device is a MacBook Pro (15-inch, 2.53GHz, Mid 2009), OSX El Capitan V 10.11.6, 2.53 GHz Intel Core 2 Duo, 4 GB 1067 MHz DDR3, NVIDIA GeForce 9400M 256 MB. This error does not occur in Safari. Firefox is my preferred browser.

Hello. I recently noticed an issue with Firefox. When I open it the first time, no Tab is showing and neither is Minimize, Maximize and Close on the top right. If I close the browser and reopen it, those 4 things that were missing, come back. I noticed a little bit later, that if I keep closing and reopening it, those 4 things keep disappearing the 1st,3rd,5th,7th,9th time I open the browser after closing it. So, as you see it's like a cycle. Other than this issue I really like Firefox. I've been using Firefox for years.

Never had this before. I opened firefox this morning and restored the old tabs as I usually do every morning. They all opened up (e.f. tab with the correct title) but the address is empty and nothing loads.

Attempted in order: - open a new tab, would not even load google, simply a white page - same action on new window, same result - refreshed firefox= nothing - uninstalled firefox = no luck - removed the apps I installed in the last days (visual studio code) - installed firefox from scratch (no account sync) 82.0 (64-bit) nothing at all. Same result see image in attachment.

I also have: removed all cookies/cache (refresh would do any ways), scanned my computer for viruses (nothing found). It doesn't open the options from the menu, it doesn't show anything under about:config

Windows 10 2004

In 15 years I'm using FIrefox I have never seen anything like this :-o

Firefox ESR on Devuan, both 2.0 and Beowulf, has a problem involving resizing. Webpages that formally displayed fine now are too large (the indicator shows 100%, but I must reduce it to 80% to display as it did before). Other Linux distributions, for example, Linux Mint and openSUSE, do not have this problem (PaleMoon on the Devuan system does not have the problem).

The hardware is old: Intel 3rd Generation Core processor, 8 GB memory, SSD connected via USB 3.0.

The best solution might be to run both Firefox ESR and regular Firefox. I can download the latter, extract it, move the folder to the desktop, and double-click on "firefox" to start it, similar to how I run PaleMoon. Is there a way to avoid them using the same profile?

Youtube works fine on other browsers like edge and chrome.
