I have version 43.0.4 and I get constant prompts to update to the latest version. I have tried to find this many times, to no avail. I get a message that states "updates disabled by your system administrator". Since I am the administrator, how do I log in and get access to change this setting so I can get the latest version?

I have followed the instructions in the support section very carefully and still cannot get Firefox to update. I did see the note that the person who is the admin or the person who installed Firefox is the only person who can update it. That would be me and me alone, and I've exhaustively checked my Mac's settings and preferences and everything else I can think of. I'm new to Mac so I may well have missed something important during set-up...........but I can't figure out or find what that may be. Whenever I follow the link on the support page that says I can update, all it does is download the updated version of Firefox, not an update. I don't want to start all over and lose all of my bookmarks and developer tools just because something isn't working. I realize it is probably something rather simple, but I just seem to be missing it and I've passed the frustration point now.  :) Thanks for any assistance in getting this straightened out!

I use Win XP SP3 with firefox v 43 but no matter what version it is it keeps crashing. The whole windows is a new installation like firefox itself. I noticed that crashes started after I installed adobe flash player. It used to give me troubles in the old installations as well. The question is: Is the new firefox really compatible with WinXP? How about the flash player? How to troubleshoot pls?

I really want to use Google talk! Is there any way to allow GoogleVoiceAndVideoSetup.exe through and create its google plug in? I have an 2002 W XP and 2005 W7pro (formerly Vista) but both have issues from heavy use, missing keys, etc. So I acquired 2 2009 computers, one W7, one very nice one but unfortunately W 10. I know there is not much hope to get any cooperation with W10, but is there any hope I can get GoogleVoiceAndVideoSetup.exe to work on this W 7 pro machine with the big beautiful screen?

Do I have to run an older version of both FF and Flash to create the plug in first? Please help me because we are usually without phone lines for months in the winter and we have no cell signal here. This way I can call ATT from the firestation/library to tell them the lines are down! (This usually takes an hr call for 5-14 days until it is taken seriously here. We actually miss coin phones here!

Or is there any other non-credit card phone we can use online to call and receive from phone numbers? I used to have Skype, but when it became Microsoft they took my credit and I can't call phones anymore. Is there anyway to make FF compatible with GoogleVoiceAndVideoSetup.exe again? Thank you, Walks Dogs

How do I get 1440p Youtube videos to actually play?

Whenever I try to play a video on Youtube that is higher than 1080p, it won't play. The player will just show me the loading animation and never start. If I wait a while, this message appears for a short time before disappearing again: "if playback doesn't begin shortly try restarting your device". Switching to 1080p, the video starts immediately and plays just fine.

These high res video's have never worked for me. In older versions of FF I had the video play garbled, with the top of the video showing an artifacty mess, and the rest of the screen showing a frozen picture or black. In newer versions of FF the above mentioned behaviour of eternal loading.

My monitor is 2560 x 1600. In windowed mode I view video's typically at 1080p, but if I then switch to full screen, Youtube automatically tries to give me the 1440p version of the video when available. And subsequently stops and shows the loading animation.

This isn't a bandwidth problem (120 Megabit connection).

I've tried FF safe mode. I've tried disabling hardware acceleration. My Nvidia drivers are recent. Disabling SLI didn't help either. My plugins are up to date, including Flash, even though Youtube had been serving me videos exclusively in HTML5 for a long time now. But just to be sure.

I would really like to watch video's in 1440p, or even 2160p in the future on a new monitor. What can I do to fix this?

Edit 1: I've added a screen shot of a video's 'stats for nerds', when trying to play at 1440p.

Edit 2: Setting "media.mediasource.webm.enabled" to true didn't help. Youtube's youtube.com/html5 page shows me seven blue checkmarks.

Mozilla support does not receive these questions and calls for help?...this goes to community? How customer facing is this? Not very.

I just set up Firefox this morning. I used it years ago but became disenchanted with it dropping my sessions and telling me that Firefox cannot find this site.

Today, in the short time I have been using Firefox again I am repeatedly asked to log in on Facebook & Yahoo mail. Those are the only two sites I have been on today. I could not sign in fast enough on Yahoo Mail to keep up with the sign in messages so I got out of it.

I just set up Firefox this morning and Just being on Firefox such a short time it has so annoyed me by asking me to log in again, again and again. 20-30x and I have not been online much today. This is absolutely ridiculous.

Having people choose to be kept logged in and to save their passwords to try to get around this failure of Firefox is incredible. It is unsafe to their sessions on those sites and it also makes them more exposed to break ins by crooks.

I am not sure what to do to avoid this short of not using Firefox. Does anyone have a solution for this?

Thanks, jaaess

I have two computers with the same symptoms. Both are Windows 7 x64. One is Pro the other is Home. Both have recently been scanned for infections.

In both cases, Firefox opens fine, but opening a page like news.google.ca takes 15-20 seconds. (On the same computer, Chrome opens news.google.ca in about 2 seconds).

When I close Firefox, the firefox.exe thread stays running for about 30 seconds (if I try to open Firefox again, I get the message saying the Firefox is running and needs to be closed). If I just wait, I get the Firefox crash Window, which asks if I want to send a report.

Here are the ids of the crashes from one of the computers: bp-d2d8f132-6824-45b6-a66f-3f7132160125 25/01/2016 2:48 PM bp-1f47d49a-3a24-4804-9e74-3b6942160125 25/01/2016 2:26 PM

Here are the crash ID from the other: bp-8c7a7c83-98af-42fc-bfdb-79d642160125 1/25/2016 1:35 PM

I've uninstalled Firefox, renamed the Mozilla folder in %appdata%, Program Files(x86) and removed the Mozilla entries from teh registry and reinstalled. No change.

I've updated video and chipset drivers on both (one is Intel-based and one is AMD).

Any suggestions would be great!

Thanks!

I have been having an issue with Firefox freezing "sporadically" on my PC. In a nutshell, Firefox freezes typically once per boot-up cycle. By freeze, I mean that my whole PC locks up and is unusable, no clicking is allowed for any task, but my mouse is free to scroll around. Once the computer unfreezes, typically under 1 minute later, whatever action I had taken will pop up (including but not limited to ctrl-alt-del). This freezing only occurs on certain websites, and only after boot-up. The frequent problem I have isolated is yahoo mail, where the browser becomes stuck on "read s.yimg.com".

As far as I know, this only occurs shortly after boot up. If I magically avoid culprit sites, the PC eventually reaches a state where I have yet to witness a freeze. So say I get lucky on a few websites and edit a word doc for an hour, when I eventually load yahoo mail, it may NOT freeze.

I am currently running Firefox version 43.01. I had been using 36.04 until I updated to 43.0, and the problem started occurring on 36.04. I ran Firefox via safe mode, and also manually disabled all add-ons, but the problem persisted.

Also gave google chrome a shot, and I did not come across this same issue.

Anybody see this before? Curious for any insight you are able to provide, and a possible solution. While it may seem like a stupid question (do stupid questions actually exist?), could this be a virus? My gut tells me no, but I am no computer specialist.

Thanks!

I have always edited under 'manage my web page' but now I cant access it. This happened in Safari and it was a security upgrade that blocked me. I used Firefox as it gave me access which is now not available - have you done a security upgrade or other that affects my access?

I am unable to get Firefox (43.0.4) to export my bookmark or json file. The files are NOT created.

I've tried refreshing my profile, but that didn't help. While I realize that there is a places maintenance extension, I'd like to know what is causing this issue and to find a permanent solution as I backup my data files quite regularly. I can see the places.sqlite file, so I know it's there.

I've not seen this issue before and would appreciate any advice or suggestions on why this happened (corruption?) and how to fix it !

Many thanks.
