Firefox won't recognize javascript

I got 2 replies for my problem. One was too technical. The other option, disabling No Script and AdBlock, doesn't work. I did come across a new option which was to type "about:config" in the address bar, and eventually found that javascript is marked as true.
Something else that might be helpful to the person reading this: Another help page says to go to Options, then Content, check off Enable Javascript. My Content page doesn't show that. I have Firefox 30.0

Sorry to be the annoying guy, but to provide the readers with full context and avoid duplicate suggestions, it would be better to post updates and followups in the earlier thread here:

Firefox won't recognize latest update HP simple pass

I have tried everything and about just to say the heck with it and go back to IE9. But, I will ask.
WHY does Firefox refuse to recognize the latest upgrade to HP simple pass (Egistech) that is loaded onto my computer. It keeps saying the current 5.0 version is not recognized. Ok, I understand this, but I have loaded version 7.1 and firefox evidently cannot see it and keeps telling me 5.0 is installed.
Am I doing something wrong, or is Firefox just worthless and IE9 is the way to go?

Does Firefox find other plugins placed in that folder?
Note that you need to place a symlink to the libnpjp2.so file and not the actual file.
You can also try to create a plugins folder in your home directory: ~/.mozilla/plugins

Firefox won't recognize the "file://path" construct.

How would I code a link in source code so that I can link to a file on a local server? The standard "file://path" or label or label constructs are recognized by IE but not Firefox. Is there a coding that most browsers will recognize? (File is located on an office server.)
== This happened ==

Firefox won't recognize hyperlinks in PeoplePC Webmail message text

When I paste or type in a hyperlink in the body of an email, Internet Explorer recognizes it, and it arrives at the receiver's computer as a hyperlink, which he or she can click on to bring up the web page.
With Firefox, it just arrives as text, and if the person wants to look at the web page it links to, they have to copy it to the window at the top of another browser window.
Can this be fixed, so that Firefox will recognize the hyperlink automatically, and send it as such?

Thanks. It turns out I got my new computer at the exact time that FF dramatically changed their sync system. There was never a previous email or username or password, so the sign in page was misleading. Many users reading this will have to create an account, upgrade all their synced computers, unsync them, then sign in to their new FF accounts. Syncing will happen automatically.
The problem with "automatic" syncing was illustrated by my experience. Instead of syncing on the computer I wanted to copy, it synced from the computer I wanted to change. So, all my computers got all the bad passwords and duplicates of many good ones. It took a long time to straighten that out. But I made the changes on one computer and that changed the others. And new changes will automatically update. So it's an "easier" system. Still, I wish there was a way to choose when to sync. But thanks for the help anyway.

Firefox won't recognize CSS

I'm trying to figure out why Firefox and other browsers
besides IE7.0 won't read my CSS. Please visit my link in one of
those browsers and provide some assistance. Thanks for your time!!

Every time I open Firefox I need to update all my extensions because Firefox won't recognize that they've all already been updated previously.

== Issue
==
I have another kind of problem with Firefox
== Description
==
This problem only occurs the first time I open Firefox after turning on the computer, but it occurs EVERY time I turn on the computer. Every time I turn on the computer and open Firefox, none of my add-ons are seen as updated or installed (although they are all updated and compatible). I need to "find and install updates" then restart Firefox. Once this has been done, I can open and close Firefox with no problems, but it only works fine until the next time I re-boot and I have to go through that all again.
== This happened
==
Every time Firefox opened
== Started when I upgraded from 3.0.(?) to 3.5.(?).. now on 3.6.6 and still happening

Firefox won't recognize FF account username on a new install on new computer.

I know I have the right username, email, and password, because I am looking at them on my existing laptop. But on installing FF 28 on my new laptop and trying to start the Sync process, I keep getting the message "unknown account."
I am getting this sign in message when I choose start sync process on my new computer. But I can't sign in, let alone start the pairing process.
I have done the pairing process before, recently, with my desktop and my existing laptop, so I know it works. Something about FF is not allowing it to recognize my correct email.
I'm on Win 8.1.
Thank you.

Thanks. It turns out I got my new computer at the exact time that FF dramatically changed their sync system. There was never a previous email or username or password, so the sign in page was misleading.

Firefox won't run Javascript while downloading a large file

Ok, I've coded a small site featuring a fairly large flash component, and to facilitate things I've incorperated an HTML 5 element to act as the center of the page while the flash file loads. Unfortunately while this works find in Chrome and IE9, older builds of Flash were very slow and jerky during the loading process, and flash 4 doesn't actually do any scripting until the whole file loads, defeating the point.

Maybe an external download manager can prevent Windows from going into sleep mode.
You can use the [https://addons.mozilla.org/firefox/addon/220 FlashGot] extension to integrate an external Download Manager in Firefox.

I have a sync key, have installed Firefox 28, but it won't recognize my account?

Ok. Firefox was my main browser on my old laptop, but I ended up having to wipe it's hard drive a few weeks back.
Before I wiped the hard drive I saved a recovery key. It did not say that I needed an account, just the key, so that is literally all I have. I did not have a firefox account back then. (Note: I'm pretty sure I didn't have an account at least, because when I searched for an account on Firefox with the only two emails that I use it couldn't find an account under either.)
Now that I'm trying to recover my old data, I've read that I have to download a pre-29 version of Fireox, so I got Firefox 28 mobile, but the damn thing insists that I need a Firefox account ALONG WITH the recovery key to gather the old data. It won't recognize my new account info (that I just made when I downloaded the newest version of Firefox before realizing it wouldn't be able to sync), so now here I am. With a seemingly useless sync key, a useless sync account, and all of my old bookmarks and passwords lost to the ages.
Is there anything I can do, or should I just give up?

hello, for the old sync system in firefox 28 and below you also had to sign up with a mail address and password originally - to connect firefox to the old account you would need to have all those three pieces (mail, password & recovery key) available to you unfortunately...

Firefox 6.0.1 update won't recognize the home page which uses a password access which has been saved into 6.0.1.

Question
Firefox 6.0.1 update won't recognize the home page which uses a password access which has been saved into 6.0.1. The security shows permissions for the web site but doesn't recognize that I've been accessing the web page every day since I updated to 6.0.1. Web page trying to access is <http://classic.wunderground.com/cgi-bin/findweather/getForecast?query=zmw:98108.5.99999> This home page worked fine on earlier versions of Firefox and continues with Internet Explorer 9.0.

Looks like its been fixed for me, not by 6.0.1 but by - Todd Siechen from http://www.dvdthemepak.com

Todd... I love you xxx
After having a nightmare since first day of version 6.0.0 and still no fix after 6.0.1, even after Apple requested the files... You fixed my problem... Checked for duplicate fonts and found about 5, selected "Resolve Duplicates" and everything great, even with old projects... You should work for Apple!
Check out the 2 posts:
http://discussions.apple.com/thread.jspa?threadID=313109
http://discussions.apple.com/thread.jspa?threadID=366383
1) The first and biggest culprit we found to be causing problems is with font issues. In order to alleviate this problem, open Font Book and make sure all the Fonts that are turned on have no dots next to them. If they do then select them and select "Resolve Duplicates" from the Edit menu. If you are using a different font manager then use whatever tool is available to make sure no duplicate fonts are loaded. iDVD 6 is very sensitive to this.

I have windows 8.1 and firefox won't play youtube videos but IE will

I have windows 8.1 and firefox won't play youtube videos but IE will. I have tried reinstalling firefox, flash, java. Resetting firefox don't help, disabled hardware acceleration, protected mode 0 in the mms.cfg file. Nothing will play on youtube in firefox. It says "an error has occured, please try again later". The ads play fine though. Everything plays fine in IE. I have tried different versions of flash also with no luck. I even restored the system to a previous iso image with no luck. Does anyone have a solution?

It maybe because your javascript is disabled .
You can check the javascript.enabled pref on the about:config page.
http://kb.mozillazine.org/about:config
There are also extensions that can block JavaScript or otherwise interfere.

Start Firefox in [https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode Safe Mode] to check if one of the extensions (Firefox/Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

Firefox won't load pages, but other browsers will.

Firefox won't load any internet pages, but different browsers, both Chrome and Explorer work, I havent tried others. I've un-installed, changed the name of the folder of the plug-ins that were left so it wouldn't recognize them, then re-installed nothing happened. I've checeked for viruses, proxies, and i'm pretty sure its not a firewall, I think we only have one and I checked it, plus there is no prompt asking me if I want to allow firefox to access the internet. It won't run in safe mode, so its not any add-ons, clearing the cache didn't do anything either. Its also not in offline mode. What else could it be?

Hello,
The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
Note: ''This will cause you to lose any Extensions, Open websites, and some Preferences.''
To Reset Firefox do the following:
#Go to Firefox > Help > Troubleshooting Information.
#Click the "Reset Firefox" button.
#Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
#Firefox will open with all factory defaults applied.
Further information can be found in the [[Reset Firefox – easily fix most problems]] article.
Did this fix your problems? Please report back to us!
Thank you.

I do not see much about coloum 14, but I am guessing this file is stored somewhere and its corrupt. Update.xul suggests that it is the update file. Do you still have this in your downloads folder? There are two places for update and for a clean reinstall:
[http://www.mozilla.org/en-US/firefox/new/] in a private window will give you a new install or you can choose from here: [https://www.mozilla.org/en-US/firefox/all/]
This is what the file should look like; [http://hg.mozilla.org/mozilla-central/log/7a2edc5171e6/toolkit/mozapps/extensions/content/update.xul] If you can copy and paste that file from a working browser we can see the issue, but it will just look the same as the error.
if you can replace the contents of the file locally with what it should look like it will fix the error, but who knows if there are other errors. May be best to delete the updater and save all the profile folder contents.
