I have been using Firefox for years. When I downloaded the Firefox 20.0, I can type in my hotmail address, but my hotmail won't open.

I am able to type in the address bar, but when I hit enter, nothing happens. And I don't like using Internet Explorer. This happens when I try to acccess my hotmail account. I never had this problem with other versions of Firefox.

We are aware of issues using the address bar. A push to fix the issue will be made in 3-5 days. In the meantime since your issue is a little different that what we have you can try safe mode.
'''Try Firefox Safe Mode''' to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.
''(If you're not using it, switch to the Default theme.)''
* You can open Firefox 4.0+ in Safe Mode by holding the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
* Or open the Help menu and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.
''Once you get the pop-up, just select "'Start in Safe Mode"''
'''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one. Please follow the [[Troubleshooting extensions and themes]] article for that.
''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
''When you figure out what's causing your issues, please let us know. It might help other users who have the same problem.''

firefox.exe has encountered a problem and needs to close. We are sorry for the inconvenience.
I have been using firefox for years. I installed the latest version of Firefox. It worked fine for several days. Now I get the above message each time I try to start Firefox, even in safe mode. i have checked with latest antivirus softwere also.. i didn't find any thing suspicious.
== This happened ==
Every time Firefox opened

I was having this problem few days ago,and I have fixed.Try this steps-If you have AVG antivirus so go on firefox>Tools>Add On and Disable AVG safe search and AVG tool bars too.Then restart computer.

I've been using Firefox for years. Now your load screen appears everytime I open. It's a hassle!

Every time I open Firefox to go to the internet I get a page that says thanks for becoming a tester, etc. Then you want me to download Firefox, which I've done 6 times now! Then you make Firefox Search my homepage. Then I change the homepage. Then a screen comes up saying AVG has been successfully installed. Then I use the internet and the next time I re-open Firefox I get the same bull##%% routine!
I've been using Firefox for years. What's up? It's a major hassle!

If you do not keep changes after a restart then see:

Some security software has virtualization or sandbox features that may cause problems by protecting and restoring files in the Firefox profile folder.

I have been using Safari for years and have always kept it on "private." Starting two days ago, I suddenly found myself unable to log onto my blog and many other sites that I normally log onto when private is set. Why?

I have been using Safari for years and have always kept it on "private." Starting two days ago, I suddenly found myself unable to log onto my blog and many other sites that I normally log onto when private is set. This so annoying, I just switched to Firefox. I don't like Firefox nearly as much as I like Safari. What is happening? How do I fix the problem?
Thank you.

Might be a corrupted database ...
Open a Finder window. From the Finder menu bar click Go > Go to Folder
Type or copy paste the following:
~/Library/Caches/com.apple.Safari/Cache.db
Click Go then move the Cache.db file to the Trash.
Quit and relaunch Safari to test.

Several sites will not respond any longer when I type or click on them. I have been using Firefox for years and all of a sudden, nothing.

I have been using Firefox for many years now and have been going to several sites on Firefox. Now, after an update around two days ago, I can't do anything with the sites. The cursor stays an arrow, and doesn't click anything. It's like a blank page with print on it.
I've tried almost everything, but to no avail. It's too much to copy and paste below.
Any ideas or help would be very much appreciated.
Also, http://tesnexus.com is another site, plus a few others, besides google.com.

Hi Papajack55,
I'd try starting Firefox in [[Safe Mode]]. If you don't have the issue while all of your add-ons, extensions, and themes are disabled, you can try adding them back in one by one until you find the culprit. You should look at the [https://support.mozilla.org/en-US/kb/Troubleshooting-extensions-themes Extensions and Themes troubleshooting guide ] and the [[Troubleshooting plugins]] article as well.
Hopefully this helps!

Can not connect to the internet. This is a new problem since I have been using firefox for years.

I can not connect to the internet. I called mediacom due to the problem and they connected me to internet explorer. They indicated I should contact you for help in connecting to the internet. It appears firefox has made some kind of change since last night since I was using firefox for my internet connection last night. Something has changed. Your help will be appreciated.

The only way that file opens thru IE8 for me ''(but not actually in IE8)'' is by using the Zip Utility (then IE closes) that is in WinXP and then opening the two image files in the Windows Fax and Picture Viewer.
I think Firefox is trying to display that file because the MIME-type is for '''''text/plain''''' instead of the appropriate MIME-type of '''application/vnd.google-earth.kml+xml''' or '''application/vnd.google-earth.kmz'''
That is something that needs to be configured in the server that is hosting that file type. Sorry, I don't know how that can be fixed. The one support person here that might know lives in Europe ''(I believe)'', so you might need to wait for an answer.

Been using Firefox for years, deleted Babylon app & now I can't launch Firefox at all. I've uninstalled & reinstalled Firefox, rebooted, but that didn't solve the problem. Am I condemned to IE?

On 3/18 I used Firefox to download a translation app called Babylon to my Dell Latitude laptop - running XP Pro. I checked out the app, got all the pop-ups asking me to buy spinoff products & uninstalled Babylon. When I rebooted I couldn't open Firefox.
I started investigating, came up with a weird Pareto Logic UUS error, fixed that. Unistalled Firefox through the Control Panel. Used IE to again download & install latest Firefox. At the end of installation, the dialog box askes "Lauch Firefox now?" which I checked & clicked the Finish button. Nothing happened. I rebooted & tried to launch Firefox from the Start menu, then from the root .exe - no luck. IE launches fine; I just want my Firefox back!

i wish i could paste the error message but it is

I've been using firefox for years, and i'm very upset with the 34.0.5 update's changes to the search engine feature.

hi,
this new search engine is incredibly convoluted, and i put some real thought into why it's bad
the dropdown menu contains more things than it used to. previously only a list with icons and titles and a link to options...now only icons (with no options to include text), a reiteration of your terms and current engine, separators between each icon, and loads of potential results from auto-complete (which i disabled immediately). though taking up less space by forcing icons only, more things were added, giving the user more clutter in less space.
having a permanent default search engine is counterproductive to the feature's previous nature. this was supposed to be there so i can quickly change between websites i'm searching, now it's been equated to the search feature in the address bar (which i am now also unable to change the function of on the fly, as changing the search engine used would also change the address bar's search function - perhaps influenced this change?). it's now faster for me to type the website i want followed by my terms into the address bar, just like when i use chrome. this feature was one of the largest reasons why i preferred firefox over chrome
i would commonly leave my search engine on merriam-webster when writing papers, wikipedia when doing research, etc. and now i have to click which one i want. every time. with every search that isnt default, unless i change my default through the options constantly. this is incredibly tedious. most irritating of all is the inability to use hotkeys to select my search engine, the lack of ctrl+up/down. previously i wouldnt have to use my mouse often at all, which is imperative for laptop users
so yeah, ive put some real thought into this, and i'm very unhappy. this greatly hinders my browsing experience. heard the saying "if its not broken, dont fix it"? ive been using chrome in conjunction with firefox for a few years now, and it's been painful to see mozilla attempt to imitate it. i will be using chrome more often in the absence of this feature (i am right now, even). i'm also upset that i was unable to find a public message boards hosted by mozilla to voice my opinion, and i apologize to whoever customer support employee that (probably didnt) read this - please pass it on to the devs and tell them internet people are angry and said they fucked up. thanks.
and i beg you, please give us the option to revert back to the old interface in future updates, or at least an official extension overriding this awful update. i realize i cant request this really, and yes im upset, yes im sending an angry email - thats because this is something i use often and i am passionate about it
sincerely,
pissed

You can use the Tab key to select a search engine on the bottom bar and press Enter to use the search engine to do the search.
*https://support.mozilla.org/kb/Search+bar
In the current Firefox 34 release there is a new "one-off" search bar.
This search bar doesn't show the name of the search engine and a logo.
You can type one letter to make a drop-down list appear where you can see suggestions and see the used search engine and that also has bar at the bottom where you can select other search engines that are enabled via the Search tab in Options/Preferences.
You can use the Tab key to select one of the other available search engines and press the Enter key to search with the selected search engine.
Click the search engine icon and click "Change Search Settings" to open the Search tab in Options/Preferences (positioned between Tabs and Content) to select the default search engine and select which search engines to show in the search bar drop-down list that opens when you start typing search terms.

Firefox wont open -= wont let me uninstall because I need to close Firefox!! I have Windows 7. I've been using Firefox for years.

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.

Have been using Firefox for years, but downloaded BearShare and now it has taken over the browser. Deleted it but still have it on start page. Tried downloading firefox again and again but its still there. Cannot access my bookmarks or anything else on

Cannot delete BearShare tool bar from top of Mozilla browser.
== This happened ==
Every time Firefox opened
== a day or two ago ==
== User Agent ==
Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US) AppleWebKit/533.16 (KHTML, like Gecko) Version/5.0 Safari/533.16

Hello Joe.
If BearShare is an extension, you can go into ''Tools > Add-ons > Extensions'' to disable or uninstall it.
If it's a plugin, go into ''Tools > Add-ons > Plugins'', where you can disable it. To uninstall it completely, you need to contact its author for support, as it's done outside the browser. In case it's a plugin.
I hope this helps.
