I loaded what I guess is the new version of Firefox and it completely changed my whole task bar. I don't have my Norton Logins with stored passwords, and it's hard to find my favorites. Help get it back to how it was.

To downgrade to Firefox 3.6 first uninstall Firefox 4, but do not select the option to "Remove my Firefox personal data". If you select that option it will delete your bookmarks, passwords and other user data. See https://support.mozilla.com/kb/Uninstalling+Firefox
You can then install the latest version of Firefox 3.6 available from http://www.mozilla.com/en-US/firefox/all-older.html - it will automatically use your current bookmarks, passwords etc.
To avoid possible problems with downgrading, I recommend going to your profile folder and deleting the following files if they exist - extensions.cache, extensions.rdf, extensions.ini, extensions.sqlite and localstore.rdf. Deleting these files will force Firefox to rebuild the list of installed extensions, checking their compatibility, and reset toolbar customizations.
For details of how to find your profile folder see https://support.mozilla.com/kb/Profiles

I downloaded the new version of Firefox for my mac but it never prompts me to slide into the Applications Folder and therefore does not allow me use it.
When I open up gmail in Firefox, it tells me my firefox version is no longer supported but after I download new version, it never registers that it is upgraded.

Firefox 4 requires at least OS X 10.5 and an Intel Mac.

If you have problems with updating or with the permissions then easiest is to download the full version and trash the currently installed version to do a clean install of the new version.
Download a new copy of the Firefox program and save the DMG file to the desktop

I've noticed that in the new version of Firefox that you cannot save multiple tabs at one time like the previous Firefox 3.6.or so and I wanted to know if I can find that feature again?

I've noticed that in the new version of Firefox that you cannot save multiple tabs at one time like the previous Firefox 3.6.or so and I wanted to know if I can find that feature again?
In the previous versions of Firefox when you went to you Bookmarks menu it gave you the options to either Bookmark This Page 'command' + 'D', Subscribe to this Page, Bookmark All Tabs 'up-arrow-key' + 'command' + 'D', and Organize Bookmarks 'up-arrow-key' + 'command' + 'B' however in the newest version of Firefox there is no Bookmark All Tabs so you can bookmark all the tabs that you have up in one window at a time. So I need to know if it is possible that the feature is now in a different place, is gone altogether, or if you can get that feature another way?
For me personally and my work I go through hundreds of web pages a day and save around half of those so it is imperative that I be able to bookmark more then one tab at a time because I can't be bothered to bookmark every single page separately and then go through hundreds of tabs in my Unsorted bookmarks in order to sort those bookmarks. It is simple inconvenient to sort every bookmark individually that is why the previous version of Firefox with the Bookmark All Tabs button was superior in its convenience.

Right click any tab and choose "Bookmark All Tabs".

After installing a new version of Firefox, I get the error message "The procedure entry point JS_GetOperationLimit could not be located in the dynamic link library js3250.dll" when I try to start firefox. Elsewhere in the forum a complete reinstall is suggested; however, I can't do that because of my company's IT policies. Is there any way to solve this problem WITHOUT a complete reinstall? Thank you!

If you can't reinstall Firefox yourself then you need to contact your IT department and ask them to check the Firefox installation.
It is possible that some files got broken with the latest update.

When installed a new version of firefox my computer crashed. Can I run on the one that is still on my computer?

I installed the new version of firefox, like requested. When went to boot up again, it crashed and I could only boot up on safemode. Then I did not have my printer or sound available either. Also did not have a version to restore to, like I had in the past. A friend told me to go to run and uncheck all startup menu and reboot. I did and here I am with another request to install a new version of firefox. Very afraid it will crash again. I have Windows 7

Please update to Firefox 19. If it crashes, come back here and we will give you information on how to get the crash Id's so we can fix what is making it crash.

After downloading the newer version of Firefox, I now cannot open the NYTimes crossword puzzle with Across lite (I could do it before). Help!

Yestereday I downloaded the newer version of Firefox. I also as recommended did the same for Adobe Flash. When I went to NYTimes site to print a crossword puzzle (as I do everyday) using AcrossLite, I got this error message: /Users/mary/Downloads/Jun0911-1.puz could not be opened, because an unknown error occurred. Try saving to disk first and then opening the file.
I tried updating AcrossLite to see if that made a difference. I have a Mac OS X version 10.6.7

Mozilla are aware of the issue in Firefox 3.6.14 and are working on a fix, no timescale but they are planning on a quick release.
A workaround pending the release of 3.6.15 is to install 3.6.13, for details see https://support.mozilla.com/en-US/kb/pogo-and-other-java-pages-dont-work

With the new version of Firefox I cannot use my Google Toolbar. Can I revert to the earlier version with which the Google Toolbar was compatiable? If so, how do I do it?

I love Firefox but found it more user-friendly when I had my Google Toolbar as well. I want it back and the new version of Firefox does not allow it. Can I revert to the most recent version of Firefox which did allow Google Toolbar and if so how do it do that?

The Google Toolbar "will not be supported on Firefox 5 and future versions." <br />

The Google Toolbar '''7.1.20110512W''' version does work pretty good in Firefox 5.0 by using the Compatibility Reporter extension. But not every feature works 100%.<br />

My old pc died and i have not saved my bookmarks to a file, however i have the hard drive plugged into my new PC , how do i get my bookmarks off the old hard drive into the new version of firefox??

The old laptop died, and would not charge, beyond repair . Have removed the old hard drive from the PC and have connected it to my new PC. I have found the firefox folder but cannot see my bookmarks in it. How can i transfer my old bookmarks from the mozilla folder into the new version of firefox i have installed in my new PC??

See the great user tip: https://discussions.apple.com/docs/DOC-3141 for syncing to a new device.

I am getting an error that says there is a proxy connection that is unsupported. I have no proxy connection. It happened after I downloaded the new version of firefox.

I downloaded the new version of Firefox. When it was finished installing, I pulled up a new browser. It said something along the lines of "proxy connection error" with nothing other than "try again". I restored the computer to the previous day to counteract the download, and now firefox will not open at all.
It is a HP G600, Vista.

Check the connection settings.
*Tools > Options > Advanced : Network : Connection > Settings
*https://support.mozilla.org/kb/Options+window+-+Advanced+panel
If you do not need to use a proxy to connect to internet then select "No Proxy" if the default "Use the system proxy settings" setting doesn't work.

I just downloaded the new version of Firefox and now every site I used to use such as Facebook, Twitter, and Youtube show "This Connection Is Untrusted"

I just downloaded the new version of Firefox and now every site I used to use such as Facebook, Twitter, and Youtube show "This Connection Is Untrusted". Even when I do accept the risks the site no longer looks the way it's looked for years. Twitter doesn't even give me the option to accept the risks at all and shows this error (Error code: sec_error_unknown_issuer). I've tried resetting Firefox, I've checked the time and date, and I've removed and added Firefox to see if that would work. Nothing seems to be working so I can see the sites the way they normally would be instead of "coded". Can anybody help me please?!!! Thanks

How can I update to the new version of Firefox if I have Linux Canaima 2.0?

Hi! I have a laptop acer and I have installed Linux Canaima 2.0.3, which is a debian distribution with some features of Ubuntu. I downloaded the new version of Firefox, but could not install because it tells me that there are certain dependencies with the old version and how to do to remove the previous version of browser and install the new one. Please I need your help. Thanks in advance.

Either you need to install those missing dependencies or install a more up to date Linux distro version that has more current packages and not ones that are probably from 4+ years ago being based on a long term support debian version.
There is a Canaima 3.0 which was released May 2011 for example. http://canaima.softwarelibre.gob.ve/
You might be able to install Firefox 3.6.18 from http://www.mozilla.com/en-US/firefox/all-older.html
