I recently had a windows update on my desktop, since then videos on netflix and twitter (and a few other sites) will no longer play. Whenever visiting twitter I get a bar pop up at the top suggesting I install "Microsoft's Media Feature Pack" and links me through to this article - https://support.mozilla.org/en-US/kb/fix-video-audio-problems-firefox-windows , I have the pack installed and it's up to date, I've tired via the Add Features system in Windows and via direct download, both to no avail.

Twitter will not load or play videos and netflix is the same. On Netflix I'm getting:

"Oops, something went wrong... Unexpected Error" and error code F7355 (see this article which indicates browser trouble https://help.netflix.com/en/node/105186).

Here are some other things I've tried, none of which have worked:

  • Checking for updates on windows
  • Checking for firefox updates
  • Checking for updates with the DRM addon Widevine
  • Ensuring Widevine is "Always Active"
  • Starting firefox in "Safe Mode"
  • Using a private browsing tab

I am running:

  • Windows 10 Pro N (as said above, I have installed the media pack in several ways)

OS Build: 18362.295.

  • Firefox Developer 70.0b3 64 bit.

I've also been seeing similar issues on my fiances machine with standard Firefox but her's says that Widevine has crashed on the top bar rather than suggesting we install Window's Media Feature Pack, although the other symptoms are the same. I don't have her machine to hand to grab versions from there but everything is up to date at time of writing and I've tried the same troubleshooting techniques on that machine as well.

Really stumped on this one and I'm very reluctant to switch back to Chrome simple to play netflix videos, but likewise it's quite important I can play videos around the web. I'll try anything else to fix it at this point, all suggestions welcome!

After an auto upgrade, the Firefox 70.0b5 was all grayed out, nothing worked when I started it. So I did a lot of research and re-started my computer. Now the Firefox works, but my previous sessions/tabs still not restored. I went to all history etc but it did not have all my tabs. I went to about:profiles and the local directory seems to be empty but the root directory has files. In the root directory, I looked into sessionstore, previous.js etc folders but there was just a whole lot of letters. I am not a technical person and don't know much about computers. How do I restore the previous session tabs that were on my screen before the upgrade? It's quite urgent and I appreciate your assistance as soon as practicable. Thank you so much!

Firefox lags my PC for a second when entering or exiting full screen, locking my cursor in place as well. This happens when either pressing F11 to enter full screen or bringing a YouTube video into full screen. This also only seems to occur when hardware acceleration is enabled, even though my GPU drivers and Windows are up-to-date.

Since the last but one update, Google has now reverted to the style it was about 20 years ago! It is very basic in its appearance. This has happened to other browsers at various times. Looks like Firefox needs another update to fix this. I don't really want to go to all the hassle of going back to an earlier version.

The newest release 70.0 disables ANY AND ALL of your personas - they worked perfectly in the previous version. The ONLY SOLUTION IS TO one by one, uninstall and then reinstall any or all of your favorite personas - NOTHING ELSE WORKS - WHICH IS BULLCRAP. Mozilla needs to test ALL UPDATES BEFORE MAKING THEM LIVE - but they OBVIOUSLY don't and then WE are left to figure this junk out on our own. HEY MOZILLA, "GREAT BUSINESS MODEL YA' GOT GOING - NOT!!!!!!!!!!!!!!!!!!!!!!!!!!

SO, does anyone even know if they Mr-Know-it-Alls that code this are even aware of what they screwed up but more importantly, do they even care??!!??

I am going to keep saying this until someone in the development area responds with a REASONABLE reply.

Starting with FF 69, there is no way to allow Flash to run without being authorized for EVERY site, EVERY time one visits it. The developers have cited the fact that Flash itself will be discontinued by Adobe at the end of 2020 as justification for this. That is still over a year away and I see this move as very premature AND very user-UNfriendly.

It has been less than a month since FF 69 and I am already tired of having to authorize the plugin every day on the three remaining sites (that I visit daily) which still require Flash because they have not upgraded to HTML5. While I understand completely that this is an industry-wide matter -- that Adobe itself will discontinue support for Flash -- Firefox's developers have made the (IMHO) absurd decision to inconvenience users more than a year before this move became necessary.

What I would like to see is, when the pull-down menu from the "Lego block" displays, is an option under "Allow" to let the user designate "Always allow for this site". Once coded, it would never need to be removed, because as sites do convert to HTML5 there would no longer be a "trigger" for the Flash plugin.

PLEASE, those of you developers who made the change in FF 69, do not perpetuate the image we all have of you as being heavy-handed and uncaring about Firefox users. Make our lives easier while we wait for our favorite sites to upgrade. Let us allow Flash to run, only on our specific sites, without a daily inconvenience.

Admit you "jumped the gun" and do the right thing by us.

I use a mac mini.

Firefox updated sometime today. Now it won't connect to Amazon - Really? I sell on Amazon. I need to work. I cannot take 2 hours to fix Firefox and I am not very well versed in trouble shooting.

It doesn't connect when I type in the address bar It doesn't connect from my bookmarks It doesn't connect when I google Amazon and try that link It doesn't connect with or without www.

If I don't find an answer that I can use quickly and easily, I will be going to Safari. I'm used to Firefox. It has been my go to for 15 years. This is ridiculous.
