I was using Firefox without problem until the last few weeks on my 3rd Gen Carbon X1 running fully-patched Windows 10 64-bit. At some point, it just stopped launching. I have tried everything suggested here https://support.mozilla.org/en-US/kb/firefox-wont-start-find-solutions without luck.

In particular, I uninstalled Firefox with Windows 10 "Add and Remove Programs". Then I deleted all Mozilla/Firefox folders under \AppData. Then I went through the registry and deleted every Mozilla or Firefox key. I rebooted, and reinstalled Firefox from scratch using the installer. There are no errors on installation; however, when I then try to launch Firefox, nothing happens (the process is visible in task manager or pslist, but otherwise no windows opens). I have also tried launching firefox.exe from the command shell; likewise, no errors or other response--it just stays spawns the pid but then no window opens or other visible indication that Firefox is there.

I've tried variations on this uninstall/purge/reboot process several times without any progress. I just can't get firefox.exe to launch at all on this system. Otherwise, the box seems to functioning perfectly, and all other common web browsers work fine.

I've also tried launching in safe mode (via command line or keypress) but get no different result.

Any ideas for narrowing the issue?

Firefox Sync is missing saved logins (fetch data correctly but don't use it)

Hi,

I installed Firefox Nightly (56.0a1 (2017-07-22) (64-bit)) and enabled sync for bookmarks and passwords. Bookmarks were synced correctly, but not the passwords.

I can see a the file logins.json in my profile folder, with the logins content. But if I go to Preferences->Security->Saved Logins the list is empty. Also, logins form field are not auto filled.

None content was imported manually. Nightly somehow synced and downloaded the logins.json, but apparently it's not using it.

I already did this exact same process (reinstall in new machine + sync) without any problem, except for this time/version. May it be a bug?

I already tried some forum solutions: connect/reconnect account; delete signedInUser.json; restarting; etc. Everytime the logins.json is correctly fetched from the web with the content, or the bookmarks are synced correctly, but Nightly apparently is not 'using' the contents of this file.

Thank you,

Mario

I do like to know what is the file that triggers when you launch the Mozilla Firefox for the first time to create the folder under AppData either Local or Roaming because i want to change it to a different name since i want to have 2 versions of mozilla in the same computer and the old version i want it to customize for my company web application only. I have open all the files with extension *.JS but none of them have the parameter to create the folder I have also look into every INI file inside mozilla firefox application but no info was found as well. I have use the ORCA MSI editor to reveal the registry keys but I am not sure since many of them leads to the Mozilla folder but none to the Appdata either Roaming or Local. Please let me know if you have some hints or files that i need to edit to modify that name to perhaps MOZ2015 Thank you in advance for your reply

I was happily using Firefox & though it bombproof. Yesterday I tried to update, the update went through the process right until the end and then said something along these lines: *****installation interrupted****

So far I have tried these things: Offline installer, it just extracts then does nothing. Safe mode, then try the installer, same thing. Tried to uninstall firefox and delete anything on the computer that was firefox related. Tried rebooting of course. Kept trying the installer several times, also tried version 26. Run glaries & Iobit registry and system cleaners. Tried some solutions mentioned on this forum such as the "temp" folder tweeks. Still no progress.

I really really like Firefox and do not want to have to use IE.

Please help :)

What I am trying to accomplish is on my work pc I want one instance of firefox with my work account, like normal, but I want to have another with my personal account without them getting mixed. Being able to access my data and send tabs to my cell phone would be handy, in fact, I needed it today when my printer died and I needed documentation out in the shop. I have tried to create another user account and shift+right click>run as different user, but it opened up firefox just like it is when launched normally, logged in and all. I have tried straight up installing another instance; obviously the firefox installer does not allow that. The only thing I haven't tried that I know to do is run the second instance of firefox in sandboxie, which I dont really want to do, like I dont want to log out either (switching users on my work computer actually causes a bsod) I would greatly appreciate some help. The one thing chrome has over firefox is the ability to switch accounts on the fly, though I greatly prefer firefox's way of logging into the application in a more unintrusive way. Even if I could just send a tab to my phone from a different account (share tab from work to personal account) that would suffice.

Dozens of people have strongly complained about Yahoo inserting itself in Firefox and hiding itself so it cannot be removed. This has been going on for at least a month.

Why doesn't Mozilla do something to prevent Yahoo from HACKING into Firefox.? It is an obvious attempt to pre-empt people's browser of choice. Surely there is someone in the Mozilla group who can either alter the code to block Yahoo or at least come up with a solution that lets the average user remove the stupid Yahoo software.

Thanks

I have Win XP SP3 and FF 52.5.2, Since installing FF 52.5.2 esr and the coincidence of Norton withdrawing its toolbar my Firefox became very sluggish and malfunctioned at times by not allowing me to type into my FF home page search bar (Google) and bringing up my Bookmarks list instead. Consequently I refreshed Firefox and at the moment it seems to have helped. I haven't had a malfunction since (touch wood).

What I would like to know is if I decided to uninstall my FF altogether and reinstall with 52,5,2 esr is that a complete version of Firefox, I ask this because my current Firefox in the Control Panel shows a size of 116 mb and the FF 52.5,2 setup is 43.3.mb.

When going to Netflix I get the message

"Firefox is installing components needed to play audio or video..."

but never completes. If I try to run a netflix video my pc crashes, won't reboot until I do a power off.

The desired videos play on Netflix in IE fine.

I have NO antivirus running, FF is set to auto update.

Any ideas ?

Using Windows 7. I have been running firefox for years. 3 weeks ago firefox wouldn't connect to the internet. Tab was saying 'forbinder...' in danish, that would translate into 'connecting...'. Nothing happened. No matter which website I tried to access, or which tab. Other browsers worked fine. I assumed an automatic update had gone wrong. I uninstalled, and got a fresh Firefox. It worked, and it had kept all my settings. Then some time after, I had the same issue. Could not connect. I used windows uninstall and installed a new copy. Worked. But then it happened again. Forth time around I decided to get rid of the mess. I used windows 'remove program'. I deleted the folder C:\Program Files (x86)\Mozilla Firefox, the %APPDATA% roaming profile data also. And then did a fresh install. However, I am back to my old problem. I can't get thorugh to the internet. It is saying 'connecting', no matter which tab or website I use..

I found an issue related to an Nvidia firewall - I don't have that but other Nvidia software. I updated all to latest. Didn't work. I checked proxy settings, changed from system default to 'no proxy'. Checked if other browsers had different settings, which they didn't. So it didn't work. Then I tried messing with the Windows firewall, which is the only one running. When it didn't succeed I deleted firefox as recommended, to let it selfdefine at next startup. But windows firewall is apparantly not triggeded by firefox starting.

Help, please ;-)

After the April 2018 MS Update on my Desktop I can no longer launch Firefox but it shows in my Task Manager as running (no CPU time). I have uninstalled it, and installed lower versions for my XP SP3 OS and the same problems exist. These are all the versions I've tried to install for Firefox: 52.2.1esr, 52.7.4esr, 52.0.2esr, and 45.9.0, and the same problem exists after exhausting help in the Firefox Community SUpport.

If Mozilla can't help me to launch Firefox I am going to have to switch to another browser like Chrome. What are my options? Please help. I'd like to continue using Firefox as my browser since IE is no longer supported on XP.

I need newer Firefox due to some frequently used web pages, so I need an install procedure that will not hammer anything. It's a mission critical user environment. If anybody has positive experience with Firefox upgrade in similar environment please advise.

The FAQ’s says that Mozilla Firefox will review and announce in September 2017, the final date that Firefox will issue security Firefox ESR Updates running on Windows Vista Home Premium.

The previous announcement was some rime in September, but that the final decision had not yet been made as a review of the number of Vista users would be undertaken in September 2017.

Can Firefox ESR team please state and also place a message in Firefox Help or About Firefox to say what the final decision upon ending Vista security support is.

I use v52.3.0. One person has said Firefox will continue and it will be V59.

What is Firefox own team current final official answer?
