I am unable to access my GlobeInvestor Streaming Quotes (http://finserv.globeinvestor.com/fcclient8/mainframe.htm) via GlobeInvestorGold.com. When I click on the "Tracker" link on the GlobeInvestor Gold website to access my streaming quotes, I get a pop up with an error stating:

I have restarted Firefox numerous times. I have reset Firefox. I have re-installed Java a few times and I have also updated all plugins. I am running Firefox on my MacBook Pro. If you could provide any assistance, I would greatly appreciate it. Thank you so much in advance.

have a website for a FLVS course that within firefox we always get: a plugin is needed to display this content but are able to see the site fully in Chrome.

How do we find out what plug in to install in firefox to resolve this issue.

I got a notice of a Java update. Installed it. The verification did not work. In add-ons> plugins IS NO JAVA AT ALL! It's no place else either. I have 43.0.4.???

Mozilla Firefox updated to version 36.0. When I click on the Firefox icon to open it I receive the message: "Mozilla cannot find runtime" I receive the same message if I try to open Firefox by selecting "firefox.exe" from within the Program Files. I subsequently uninstall Mozilla Firefox and reinstall it. It will open and run normally right after the re-installation. Then if I close the program and try to re-open it again, I get the same "Mozilla cannot find runtime" error message.

The only way I can get Firefox to open is if I uninstall and re-install it every time I want to open it after the initial re-installation.

I recently reinstalled Firefox on my computer and there is now a plugin called "OpenH264 Video Codec provided by Cisco Systems, Inc.". I have used Firefox for quite some time and have never seen this. Is this supposed to be there. Does it come with the Firefox download now?

I get this error message on *any* secure site I go to (youtube, gmail, Wikipedia, even Mozilla.org)

Or this one...

Your connection is not secure

The owner of www.youtube.com has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website.

This site uses HTTP Strict Transport Security (HSTS) to specify that Firefox only connect to it securely. As a result, it is not possible to add an exception for this certificate.

www.youtube.com uses an invalid security certificate.

The certificate is not trusted because the issuer certificate is unknown. The server might not be sending the appropriate intermediate certificates. An additional root certificate may need to be imported.

(Error code: sec_error_unknown_issuer)

Checked in Options>Advanced>View Certificates>Authorities and it looks like there are plenty of root certificates there. Tried removing and reinstalling Firefox, and I still get the same error. What's going on? I couldn't even connect to Mozilla.org with Firefox, so I had to post this question with Internet Explorer.

Long time user of FF on my PC. Have now got a new Samsung Smart tv and would like to use FF on it. Can it be done, and if so, what exactly do I download, and from where?

Many thanks in anticipation. Glh11

Sorry guys, i am disgusted with this upgrade. 29 does not seem like a good ui update at all. The menu bar looks really bad and so does the tab. Furthermore this does not solve my other tab issue i have either in another question i have asked.

How can i revert back to my last version with all my tabs/windows/history restored? I will do a system restore if i have to and then cancel all automatic updates. I honestly dont care if it gives me a bigger security risk.

How do I stop Bing from opening everytime I start FireFox, open a new window or tab in FireFox? When FireFox starts I have my options set to open with my homepage.

The mail program on Yahoo has been frozen in Firefox, no other browser. Yesterday, I opened it, and i was unable to delete mail because the whole toolbar with delete, reply, forward, spam, etc. was no longer on my mail window. I tried to send an email, but this function was also disabled.

Basically, the only thing that Firefox enables in Yahoo mail is loading new emails. I had to use Safari and Chrome to perform these functions on the toolbar that is still missing in Firefox.

What happened? How to restore these functions?

So i was watching a video on youtube as a game had frozen, decided to open task manager to end task for the game, then noticed there were 5 processors of firefox running, just wondering why are there 5? all i was doing was watching youtube.

I have Ubuntu 10.1 and want to install a new version of Firefox. I have downloaded the tar bz2 file from their website. I have it in my Downloads folder along with an extracted file folder Firefox. I guess I can remove the old version in Terminal with: sudo apt-get remove firefox. My question is, what Terminal command string do I use to install the new tar file? I guess it will have to point to the extracted folder or the tar file in my download folder.

I can run the new Firefox from the download firefox folder but it will not save any of my bookmarks when closed.

btw none of the older links work for install.

this affects my computer profile only(windows 8) , and only on Firefox. I have disabled SSL on AVG as the help pages suggest, and have tried reinstalling, both with no effect. Anyone know how to solve this?

As of midnight 12/12/14, Firefox started blocking plugins (in this case, Adobe Flash and Java Deployment Toolkit, possibly others as I've just been to websites that use those), saying that they're out of date. When I click on "Update Now," the Plugin Status page tells me that all my plugins are up to date. (I'm currently running Flash 15.0.0.239 and Java Deployment Toolkit 10.71.2.14, for the record.)

I get the point of this feature, and I really don't want to permanently turn on "always allow," but having to click two "allow" prompts every time I load a website that features Flash is quickly making web browsing intolerable. I'm on the verge of switching to Google Chrome over this.

After Firefox updated my version to 33, the application launches to a black screen. I've tried uninstalling my version and reinstalling the current version (33) and it (Firefox) still launches to a black full sized window. No other issues with other applications.

The main use of the PC in my living room is as a media center. My GUI (Plex) runs in the browser and plays videos with VLC via a custom addon. Currently it is also used for browsing from time to time and I need to keep that part of it secure. As Mozilla is about to break all my addons as well as force me onto 64 bit, I've no choice but to stop updating Firefox on that PC.

I found a old post (3 years old) about running two different versions of Firefox at the same time. https://support.mozilla.org/en-US/questions/974208

Is it still possible to do this? Does the same methods still work?

I want to freeze my current 32 bit Firefox at v54.0.1 and use it only for local content. (I've already disabled updates on it)

Then I want to then install a second 64 bit Firefox v55, use it for internet, and allow it to update normally.

If this isn't possible I'll just have to switch to a different browser.

For the past week or so I have been unable to play any Netflix videos in Firefox. Netflix works fine in other browsers and all other video streaming sites I've tried in Firefox still work. Initially the problem was that I would just get stuck on the red loading circle, however, after updating Firefox to the latest version (version 53), I now get an error message on Netflix telling me to check I have the latest version of Firefox, with an error code, F7702-1003. A solution posted from about a year ago involving changing the path in profiles.ini did not help, nor did removing pluginreg.dat.

I would be grateful for any assistance.
