To begin with, The computer is WindowsXP Pro SP2, with fresh NVIDIA GeForce 6600 GT drivers version 295.73, and fresh directx version 9.0c

Firefox is a fresh new install, version 35.0.1 downloaded 2-4-2015 and virus checked There have been no preferences modified with about:config The user profile is new, all previous have been abandoned

Adobe Flash has been uninstalled, then reinstalled to the latest version. All plugins are disabled except OpenH264 1.3, Shockwave Flash 16.0.0.305, and Java SE U75 10.75.2.13

Video players partially load, but video never even begins to play.

I can load up Avant Browser Portable and they work exactly right, on the same computer. I can load Firefox 35 or 27 or whatever version on a different WindowsXP computer, and then the videos will work.

It is just the XP-Pro system that will never play videos in Firefox. I've tried all that I can think of besides reinstalling Windows itself.

How do I fix this problem?

I recently upgraded to 36 and am running Windows8.0.

I opened up Firefox after the update and it worked fine until it suddenly stopped connecting to the internet. It doesn't say that it can't connect to the website, it just sits there with the loading charm circling endlessly.

I can restart my computer and use the "Delete Parent.lock" fix, but it doesn't last for more than about 5 minutes. I also can't untick the box for "Read Only" on the folders for profiles. Rather, I can, but it reverts after hitting "OK" and closing the Properties.

Refreshing Firefox after rebooting my computer worked for about the same length of time, so that fix will not work.

This started to happen two days ago. I'm using Firefox 36.0.1 on my brother's laptop, always using private browsing, and things seem to work fine for 5-10 minutes. After that, the browser won't load or refresh any website at all, it just shows the spinning wheel and/or a white page, with no error messages.

After trying to close and open process again, I receive a dialog saying that Firefox is running already. I can see the process running but I can't close it with task manager. Have to reboot and manually delete the parent.lock file on my profile folder.

Once I can open it, after 5 minutes, it happens again.

What I've tried: Deleted cache, cookies and history. Disabled extensions. Disabled Javascript. Went to normal browsing. Went Into safe mode. Made a new profile. Refreshed Firefox. Uninstalled and reinstalled.

Last seemed to work, installed Adblock and managed to recover my bookmarks. Worked for 1 hour, then it happened again.

Checked for my firewall, there was an exception already. Checked my antivirus, my brother's laptop uses Avast, disabled webshield. No need to check for proxys, don't use them. Everything was working fine till two days ago.


Posting from my desktop computer. My current browser has more plugins and extensions installed. This one works fine. So I'm putting my brother's specs.

Version: 36.0.1 Extensions: only Adblock Plus and Download Helper Plugins: Shockwave Flash and Java all up-to-date. OS: Win 8 64bit Sys Specs (don't know if this is relevant): Intel I7 3,5GHz 8GB RAM

After some time (hours or days) firefox stops loading pages (showing "Connecting..."). CPU usage of Firefox process as about 10% (my computer has 4 cores). If I try to exit Firefox, the process remains to hang forever until restarting of computer. So, I cannot just stop Firefox and start it again.

Hello Mozilla, I'm using Firefox 36.0.1, my OS is Windows 7.

After I update to Firefox 36.0.1, every time my network disconnect ( my router is disconnected once a day), I can't use Firefox so that I must close it. But after closing, firefox process still remain and I can't terminate it by Task Manager. if I try to open application again, I will report that "Your firefox profile cannot be loaded. It may be missing or inaccessible".

So that I must restart the computer to kill firefox process. When I open Firefox again, the report is the same. I did clean reinstall once, but can't solve the problem. I'm very tired when syncing my profile again and again ( It's lucky for me because I signed an account for syncing).

Please answer me soon. Thanks for your help.

Mcafee Site Advisor has stopped working on Firefox. It works on Internet Explorer. I prefer Firefox and want to keep using it! It is marked as enabled in the Add Ons in the top right Menu. I have tried reloading Firefox. I have tried disabling Site Advisor and re-enabling it. I have contacted McAfee who say it is not a software fault of theirs. I have a new Lesovo PC with Windows 8.1. Site advisor ran for a few days then this problem occurred. thankyou

The search bar on Amazon.com has stopped suggesting items or autocompleting what it thinks I want to search for. I don't know how this happened but I want it to work again. It was very helpful for searching on Amazon.com. It is only not working for Amazon. This autocomplete option still works on Google and Yahoo, just not Amazon. How do I make it work again?

I updated my Nvidia GeForce 460 to version 347.88. I also had a Firefox update on March 13, 2015. Now my Back, Reload, Bookmark, Home, Hello, and Menu buttons will not show up. My tabs are blocked out, and I don't have an New Tab nor Exit button on them. My Exit button for Firefox is about half normal, can still see the Min/Max and other half of the Exit button, but it seems shaded.

The old Firefox process must be closed to open a new window".

I'm unable to launch Firefox at all, I've scanned for viruses, cleaned regeristry, reinstalled, restarted PC several times. Looked online for hours, nothing helped. Frankly I'm at a loss at this point.

Error message is: ""Windows cannot find 'C:\ Program Files (x86)\Mozilla Firefox\firefox.exe" - I checked and the file is there, clicking on it directly bring up the same message because...fuck logic I guess? Anyway like I said I'm at a loss, any help would be immensely appreciated.
