The version 20 worked well. Now the one and only choise is "Get me out of here". I renew the certificate but even "I understand the risks" did not help in the version 21. Now I have to run IE to get the online meeting opened.

I'm looking for a way to disable the command line -private option. Kind of need to peek at the source code for browsercomps.dll to see which component parses the command line. Does anyone know where the source code is located? I'm running Firefox 21 on Windows 7.

I have my system set to minimise windows by double-tapping/clicking them on the title bar. It works for most of windows (iTunes being exception). It's a system preference thingy, so it should work across all the board. After the recent update to 21.0, my Firefox is unable to minimise by double-tapping on the title bar anymore. Is there anyway to fix this issue, or will this be solved in the next update?

Firefox version 20.0 was crashing frequently. I upgraded to V21.0 and crashes continue.

Crashes are: - Infrequent and not consistent. Happen on text-based sites as well as sites that use Flash. - Cannot be replicated.

I have scoured technical support sites and, based on their suggestions, I have done the following: - Upgraded Flash, Shockwave, Adobe Air. - Started in Safe Mode - crash occurred. - Uninstalled Firefox completely using Revo Uninstaller and reinstalled. - Removed AVG Free using AVG removal tool and reinstalled. - Updated video driver for ATI Radeon HD4200 video card.

Until today I wasn't having any You Tube problems. I haven't added anything different, but today I have been trying to answer posts on videos and now all of a sudden when I try to post an answer It won't post, all I get is "error try again" but nothing will happen, I went to IE and no problems so this is a Firefox issue.

How do I fix this problem?

I have downloaded a JNLP file from http://phet.colorado.edu/en/simulations/category/physics for a physics class that I'm taking, but the file will not load or start in Firefox. Java Web Start has already been installed by the system administrator but there is no file association for, nor is there a "JNLP" file type listed in Firefox --> Tools --> Options --> Applications

How can this be fixed so that the "JNLP" file type is listed in Firefox --> Tools --> Options --> Applications?

If you can get me that far I can do the rest by making the file association to javaws.exe. Thanks.

All of a sudden, each time I come back to my computer and wake it from standby, Firefox seems to be frozen. Tabs wont open or close, web pages wont scroll, etc. I have to shut down the browser and reopen it. I dont think I've changed any settings recently, but ...

Any suggestions would be appreciated.

I was able to disable Private Window options that appear in menus and buttons by locating the right controls in browser.xul and adding the disabled="true" attribute to each tag. I was also able to prevent about:privatebrowsing from being used for this purpose by doing something similar to aboutPrivateBrowsing.xhtml, but I still had the New Private Window task in my jump list. The only way I saw to eliminate that option was to completely disable the task list by setting browser.taskbar.lists.tasks.enabled to false. Then after finding and deleting the appropriate jumplist file from Windows' CustomDestinations folder, I now didn't have New Tab or New Window, either. These are a lot of hoops to jump through! We need a better way: give us an about:config option called browser.privatebrowsing.enabled with a default value of true, which when set to false would disable the entry point to the Private Browsing mode, even for the taskbar jumplist.

My mother was having problems with her computer on the Internet and had to reset the modem. Problem was, I was on the Internet at the time using Twitter. She reset the modem, I thought everything was okay, but now Firefox isn't letting me access Twitter at all because of the security certificate. Here's the error message:

This Connection is Untrusted

         You have asked Firefox to connect

securely to twitter.com, but we can't confirm that your connection is secure.

         Normally, when you try to connect securely,

sites will present trusted identification to prove that you are going to the right place. However, this site's identity can't be verified.

         What Should I Do?
         
           If you usually connect to

this site without problems, this error could mean that someone is trying to impersonate the site, and you shouldn't continue.

twitter.com uses an invalid security certificate.

The certificate is not trusted because the issuer certificate is not trusted. The certificate is only valid for gateway.2wire.net

(Error code: sec_error_untrusted_issuer)

gatway.2wire.net is the default error page for my modem, if the Internet is not working at all. I think the problem here is that now Firefox thinks the legitimate site for Twitter is the error page and not, well, Twitter.com. Also, I'm not getting any "add exception" option. How do I fix this?

Occasionally, a new tab will open when starting Firefox in Windows 7 or Ubuntu 12.10. This opens to the default new tab page for Firefox, which I have set to about:blank. This tab cannot be closed by left clicking the "x", by right clicking and selecting close tab from the context menu, or with "Ctrl+W". Additionally, switching between tabs with "Ctrl+Tab" and "Ctrl+Shift+Tab" skips over this tab. It behaves as if it is already closed, but improperly. I suspect it MAY be because it was loaded before the other tabs, pinned or home, as part of the normal start up procedure, but never closed, but it appears to the right of my home page tab, not the left. I would attempt to visit a website on this ghost tab to get it unstuck, but even clicking on it isn't working. As I recall, it is selected at startup, so I may be able to try that again the next time it happens. That isn't a guaranty, though, and there is also the possibility that Firefox will simply crash when I attempt to visit a webpage, as it appears to be improperly closed.

Profile Missing Your Firefox profile cannot be loaded. It may be missing or inaccessible.

^This message comes up when I try to open Firefox on my MacBook Pro. I've been using it a long time but it crashed during an update. I've tried the other troubleshooting issues, and I do not seem to have any files in the Library or Application Support. I am NOT a techie and I have no idea what I am doing. Please help! ASAP!

After selecting an email message to read, all that shows up is the to/from/date/subject at the top, but in the body text, there is nothing except a black line

I am using Firefox 21 on a mac.
