I've just installed the latest Ubuntu OS on my computer and when starting Firefox i get this problem while trying to play the latest YouTube videos where they say "Your browser does not currently recognize any of the video formats available. Click here to visit our frequently asked questions about HTML5 video." so I've tried to click on the link but then Firefox said my browser was already up to date. I've then tried to disable my adds on and try in safe mode but that did not help. I've tried installing some adds on, that didn't help either. I've tried uninstalling and installing back Firefox, that didn't work. every media.mediasource config are enabled, that didn't work. and when i try using another browser, the media can be played just fine (i used chromium). So if someone has any idea as to what might be causing this issue i'd be grateful (also, older video seems to be working just fine)

Hey!

First time I get that, I usually lose my tabs due to my mistake but this morning after starting my PC all the tabs were gone with no option to restore or any error message. I backed up my previous session json and other files by hand but every time i copy it back into my profile folder and rename it sessionstore.jsonlz4 it just gets deleted after I open firefox and none of my old tabs get loaded. I scrounged the files before and saw that they contain my lost tabs, I just can't seem to restore them. I tried reinstalling firefox too but that didn't help.

Did the restore system change or is the backup corrupt ? Thanks!

Fred

This is basically a copy of what I put in the Ubuntu forum. The problem is the same, no matter where I post it.

Originally I was using Ubuntu 18.04 LTS.

I thought it would be good to update to GG (20.10) though I did briefly try FF (20.04).

As the install was done on an existing 18.04 version things remained the same for programs, book marks, etc.

Ok, now the crunch: I USE Firefox ""A LOT"". When it loads, there are...... 8 x 6 windows of FireFox and each of those have anywhere from one to ""THIRTY"" tabs loading.

Believe me: ""It worked!!""

I could use it, also run other tasks as well - though a VM was pushing it with the RAM. But the entire machine worked.

Now, I am lucky if FireFox loads at all. Let alone let me browse.

When it loads some of the window's tops are flashing. A screen shot does not really show this. (I tried)

All that has changed is the O/S from 18.04 and Firefox from (what ever it was) to 83.0

I don't want this to be a finger pointing exercise between Mozilla and Ubuntu. I would prefer it is helpful to all.

What have I tried? I've tried starting FireFox with all addons disabled. Still happens.

I am going to try to remember to (next time) launch FireFox from a Terminal and pipe the output to a file to look for things.

The machine I am using has shown it is well up to being able to have this running. I have had it working for a few years like this.

This post is (for now) to establish there is a problem. I will post more information when I get it, rather than waiting to get it then post, as I feel there are a lot of people who have very similar problems and I want it known: ""You are not alone!""


Now a bit of extra stuff.

Other things which are weird: When I am watching stuff - youtube for example - the playback is/WAS jerky. I hadn't touched anything in the settings.

After digging around, I discovered that I had to turn ""OFF"" the hardware acceleration for the graphics. Question: How did it get turned on? (Semi rhetorical)

I have a lot of local pages I open with passwords. When I load them the CPU load goes through the roof and nearly invariably the program just exits. No crash report.

Which is a good 50% of how it happens. The other 50% is the machine just locks up and I have to power it down.

When using the dev tools, I'll frequently update the style on a page I'm editing, then switch over to the inline stylesheet to copy and paste the changes I've made into my .CSS file. For some reason when I make updates, they don't show up in the inline stylesheet.

When I make changes and write styles here: https://prnt.sc/vt6mvv

I don't see them here: https://prnt.sc/vt6n97

I used to use this feature all the time in Firefox, but then it stopped working for me some point years ago. I think it was just broken by an update, or some local issue. But it's followed me across versions of Firefox and across machines.

Which makes me wonder if I just don't understand the way this is supposed to work, of if this actually is an issue.

I use this same workflow in Chrome all the time and it works just as I expect. I'd like to come back to Firefox because I like some of the dev tools better, but I just can't work in Firefox without this working.

Any help would be appreciated.

Just recently I noticed that Firefox 83.0 is no longer retaining my viewer settings in YouTube. Specifically the theater mode and autoplay settings. I can set it to theater mode, and turn off autoplay, and the next time I start Firefox, they are back to their defaults (autoplay on, compact viewer). At first I thought it was a YouTube issue but have tried it on Chrome and Chromium and both browsers save my settings. I'm running ArcoLinux 5.9.10 with I3 WM on both my desktop and laptop. I have both reset and re-installed FF with no change.

Not sure why this page deleted my question while trying to share data but I'll start again.

I'm getting Malwarebyte alerts from something in firefox.exe, it's called restoro. It's not a program that's in my control panel so I can't delete it. It was quarantined but seconds later it was trying again. I included an image of the last scan done Nov. 28. I've deleted firefox before but it came back when I installed again. Is it something that firefox is supposed to have or is it some trojan that's latched onto firefox?

Whenever I have to go to a videoconference hosted through the browser (like GoogleMeet or Theranest), Firefox asks me to choose a camera, but it doesn't allow me to choose the built-in FaceTime camera on my iMac. The only option it offers is EpocCam, which I have installed on my phone but never use. (I've attached a screenshot so you can see that I can't choose any other camera – it just doesn't give me the option!) I must have selected EpocCam once several months ago, but I cannot figure out how to get rid of it as an option on Firefox and I can't choose the built-in camera. I've searched for hours to find a solution but can't figure out how to deal with this. I don't have a similar problem on Safari, which is the only other browser I have installed at this point; and I don't want to migrate all my stuff to a new browser just because of this presumably easy-to-solve problem. Help!

Every so often when Firefox updates - but not every time it updates - it reverts to the status of tabs from some time before: for whatever date it chooses (in the case of today it chose November 7th) it brings up the tabs that were open on that day. This means it brings up tabs I closed in the weeks after November 7th and it loses all new tabs I have opened since November 7th; if I opened and closed them since November 7th they are not in history - all tabs that were opened since November 7th disappear without a trace, so none of the new tabs that were open that I was working on are available after the update.

Why is this happening? And what can I do about it?

I have a problem with FireFox and it has been suggested I "refresh" it.

I have been down this road a long time ago and it was a world of hurt for me.

Why?

Well: a - it didn't fix the problem and b - there seems to be little documentation on "how to put things back to the way they were if that doesn't fix the problem".

So I am reluctant to do this as I have a lot of open tabs. From memory it is 47 WINDOWS (sessions?) of FireFox and countless tabs in each of those. I'd say the range is from 1 to...... 40 (at a guess)

Anyway, back to the topic:

I go through the motions. It does/doesn't work.

How do I put things back to normal? (Though yes that means the problem will remain. But if it doesn't work, it would be nice to be at least back to having those tabs I use where they were.)

When pressing the speaker icon in Google Translate, I get a toast message saying "Can't playback audio. Try refreshing page." I also have a plugin that uses an online library of sounds to pronounce highlighted words, but does not produce any audio when pressing play.

I have tried:

  • Restarting Firefox
  • Restarting Machine
  • Toggling all auto-play features, hardware acceleration, extensions, and plugins
  • Starting Firefox in Safe Mode
  • Reinstalling Firefox
  • Configuring speakers
  • Re-enabling Firefox in Windows Firewall

In the Developer console I get the following error message: DOMException: An unknown error occurred while processing decodeAudioData. (Attached screenshot)

My current Windows version is 1909

Any help is greatly appreciated, thanks.

Hi- i'm a little confused about the "collections" feature on my pixel. is it supposed to carry over onto my computer? I'd love to access my collections on my desktop. I also recently upgraded my phone- my collections haven't transferred over to my new phone and that's also frustrating. I might just be an idiot but i can't seem to find any documentation on whether collections syncs between desktop and mobile; an indication that this is generally thought to be so obvious it needs no documentation.
