If you have run into a problem, or several problems – I would highly suggest that you reset it. The reset Firefox feature can fix a lot of issues by resetting Firefox back to the day it was installed while also saving all the information you need to save.

Tired of having no way out when you run into a webpage that can not be found? TryAgain, an add-on for Firefox, will give you a few more routes to check when it comes to seeing if a website is really down or not.
This great extension for Firefox will keep trying to reach a webpage even if the server cannot be reached.
Ever have the problem of Firefox’s main browser window being a little messed up looking? What I am speaking of exactly is a large gray bar along the bottom, wish some red text in it. I have not run into this problem in a long time, but I know others have – so wanted to cover it and how to fix it.
First thing you should do is follow the common Firefox troubleshooting tips:
Check for Faulty Add-ons
Next, take a look at your extensions. It could be that one of your add-ons you have installed has a problem with it. First thing I want you to do when checking out your add-ons is to go to Tools > Add-ons and then click on the “Find Updates” button. See if updating any of your add-ons might help get rid of the issue.
The next suggestion would be to go to Tools > Add-ons, disable all the add-ons you have installed, and then restart Firefox. If the problem has gone away after that, you can then enable add-ons until the problem comes back. This should help you figure out which add-on is at fault. It could also be caused by a combination of add-ons, that do not play nice together, so do not rule that out as a possibility too.
Could it be Spyware/Malware?
This suggestion from mozillaZine might also be worth checking into:
If the problem is in Firefox on Windows, check for a file named m3ffxtbr.manifest in the “chrome” folder of your installation directory (usually “C:\Program Files\Mozilla Firefox\chrome\m3ffxtbr.manifest”). If the file exists, delete it, then restart Firefox. This file is created by the “MyWebSearch Toolbar” (a form of spyware).
Be sure to check out this knowledge base post for more tips on working with this nasty problem. Now the last and nuclear step would be to do a fresh or clean install of Firefox to see if you can get rid of the problem that way. It is a drastic step, but has worked for me in the past.
Ever have a Firefox add-on that just did not want to leave your PC? Most of the extensions to Firefox are really easy to remove, however sometimes you run into a situation where one is so bad or tricky, it just doesn’t want to let go. Here are some of the common ways to remove an add-on from Firefox.
The Traditional Way
The way you usually uninstall add-ons from Firefox is to go to Tools and then Add-ons from the menu bar. In the next Window, you should see your extensions (if not, hit the “Extensions” tab at the top). Now click on the one you wish to remove, and hit the button labeled “Uninstall”. You can do this several times if you need to get rid of several add-ons. Now, simply restart Firefox and your add-on in question should be removed.
Try Removing the Add-on via Safe Mode
Close out Firefox, and start up using Firefox’s safe mode. Try to use the traditional steps above then to remove the addon that is bugging you.
Checkout Add/Remove Programs
This might change some (depending on what version of Windows you are using) but these general directions should get you to the right spot. Click on the start menu (or windows globe) and go to the control panel. From there, you want to go to the “Add/Remove Programs” settings. Scroll down this list and see if you see the extension in question here that you can not remove via Firefox. Some toolbars and add-ons install themselves here, rather than the traditional add-ons menu from inside of Firefox.
Last (but not least) Remove the Add-on Manually
You can also remove add-ons manually, but I would leave this as a last resort. You will need to navigate to your Firefox profile folder. Once you make it there, look for a folder called “extensions”. Inside of that folder, you will see more folders with names that look like random ‘bit of text thrown together. Each folder represents an extension that has been installed. Go through each folder, and look for install.rdf. Open that up in your standard notepad program and it should tell you the name of the extension you are looking at. If you can’t find it, search the install.rdf for the phrase “em:name”. After that, the name of the extension should be given. You may also find a few themes inside this folder too. Once you find an install.rdf that matches that addon you want to remove, you can delete that extensions entire folder.
As you noticed, this pretty much covered things for the Windows people to some extent. If any Apple or Linux fans want to let me know how they do things, please drop in a comment and share with the group!
Firefox works fine, but then the worst might happen (even to you!). Something goes wonky and Firefox goes from a browsing tool to an annoyance. So how exactly do you troubleshoot an issue with Firefox?
For most people, I would suggest trying to run Firefox in Safe Mode first. You can use the command line:
firefox -safe-mode to get there (for Windows users).
On Linux, you can go to your Terminal and run (for Firefox):
On Mac OS X, go to Utilities (in the Applications folder) and open Terminal, then run (for Firefox):
From there you can disable add-ons, reset toolbars and controls, reset bookmarks to Firefox defaults, reset all user preferences to Firefox defaults and restore the default search engines.
What if Safe Mode Does Not Help?
If that does not do the trick for you, you might want to try opening up a clean profile to see if you are still getting the problem. Check out this previous post to fine out how to launch the profile manager to do so.
Key thing to remember here is if it is a problem with all of your Firefox profiles (your current one or a new one) then you might want to backup and do a clean install of Firefox. If not, then you might be able to cure you problem by creating a new profile for yourself to use from now on.
