Why does Firefox open multiple instances of .mht files?

Running laptop with WIN 7, I have changed the default program associated with file type for .mht files from Windows IE to Firefox.
Now, when I attempt to open a .mht file on my hard disc, Firefox then proceeds to open seemingly countless instances of the file. I stop Firefox after about 10-15 instances before I use up all my (4Gb) memory.

I think Firefox requires an add-on to open MHT files intelligently.
Two pop up in a search on the Add-ons site:
https://addons.mozilla.org/en-US/firefox/tag/MHT
Maybe that will help? Or if you have one of them, maybe try the other?

Just delete that file in the temp folder and cleanup that folder.

Why does FireFox open as a very small box in the top l/h corner and i have to resize it every time

Why does FireFox open as a very small box in the top l/h corner and i have to resize it every time this only occurs on the initial opening up of F/Fx after boot-up

Open the system menu via Alt+Space and see if you can resize that window.<br />
If that works then close Firefox (File > Exit/Quit) to save that setting.

Why when I try to open a PDF file in Firefox 6 or earlier versions, why does it open multiple tabs, endlessly opening empty tabs in the browser?

I do not have any PDF addons installed. Have Adobe Reader (the program) open when it does this and when its not open. Please Help before I need to select a different browser

Rename (or delete) the mimeTypes.rdf file in the Firefox profile folder to reset all file actions.

You get tabs opening endlessly if you select the Firefox program to handle a file when you get an "Open with" dialog.
You should never select Firefox as the application to handle a file if you get the open with download dialog.

Why does Firefox open new tabs when HOME is clicked?

I just upgraded to version 29.0 from a 4 year old version and I'm experiencing a problem that I can't imagine how to correct. I have two home pages set in my config, so that when I open firefox I get two tabs displayed. My Home Page field reads "https://www.google.com|https://news.google.com" When I open Firefox I get two tabs, one for Google and one for Google News.
On my old version, if I was in the first tab & navigated to www.hp.com and then later clicked HOME, Firefox would load that tab back to google. If I was in the second tab, it would navigate that tab back to google as well. The multiple Home page option was just a great help for initialization.
Now, regardless of what tab I'm in, when I click "HOME" Firefox opens two new pages, sets the first to my first home and the second to my second home and now I have FOUR tabs open. Click home again and I have 6 tabs, again and 8 tabs, etc.
There has to be a way to fix this. The HOME button is supposed to operate of the current focus, just as it does if you have a single home page specified.

Hi Stan, what both Ed and I are saying is that the first of your home pages should open ''in the current tab you're viewing'' -- the way you want -- because that's what happens for us.
Could you repeat the test in Firefox's Safe Mode? That's a standard diagnostic tool to deactivate extensions and some advanced features of Firefox. More info: [[Troubleshoot Firefox issues using Safe Mode]].
You can restart Firefox in Safe Mode using either:
* "3-bar" menu button > "?" button > Restart with Add-ons Disabled
* Help menu > Restart with Add-ons Disabled
Not all add-ons are disabled: Flash and other plugins still run
After Firefox shuts down, a small dialog should appear. Click "Start in Safe Mode" (''not'' Reset).
Any difference?

Why does firefox makes multiple profiles

My name is Mike from the helpdesk of YER.
We have one user with the same problem over and over again.
Our employees have a roaming profile with multiple browsers, but he uses Firefox wich is causing a problem.
There is a datalimit on our user profiles. The problem is that Firefox uses all the space from the user profile.
This causes a storage space error every two days.
To solve it, I open Firefox profile manager, multiple profiles are visible. So I delete the non-used profiles. But this is temporarily, because within a few days, the user contacts us with the same problem.
I also tried to move the profile to his documents with the profile manager to free space, also this didn't solve the problem because Firefox makes new profiles over and over again.
This user is the only one with this problem, and we cannot find a solution.
We thought maybe it has something to do with synchronisation between multiple devices, but he only uses his Firefox profile on his work computer.
I hope you can help me solving this problem. Maybe you can explain why Firefox is creating multiple profiles, or maybe we can change the Firefox profile path, for all the profiles incl. new ones that are created.
Thank you!

I also have been having this problem for way to long to the point I have removed Firefox so many times and have even completely wiped my computer out and did a factory full restore (which I am still upset about) .. NOW again i delete FIREFOX ... I go thru the computer ..hidden files and all and totally delete any and every thing the is related to Mozilla and Firefox.. including the OLD Firefox file it creates even if you do a reset... Now I have two issues.. when you restore a system,, you are given a complete NEW user profile,,, thanks to Firefox pulling from what must be your records.. EVERY past user ID that this computer ever had is back on my system and has permissions on important files under UNKNOWN USER.. and firefox has created tons of dupt files.. example ...I ran to see why system again was slow CCleaner disk analyzer and wow there is over 85,000 files created by Firefox which include duplicating all program files and over (I stopped counting after a certain number) thousands of c:\users\Robie\AppData\local\mozilla\firefox\profile\...\cache2 files every 4 minutes for since i reloaded.. and all system files (only important ones) and links to the old profiles that were infected and/or corrupt over 84k of this ...these are just under the OTHER catagory.. WHY is this repeating over and over

Why does Firefox open the printer dialogue box whenever it starts up

When Firefox opens the printer dialogue box automatically opens - why and how do I stop it doing this.
This never used to happen on previous versions of firefox

Some web pages will pop up the print dialog automatically. In particular, pages that websites have specially formatted for printing may do this.
Are you restoring tabs that you previously opened, or starting up with your home page(s)? I suspect that one of them is generating the dialog. You could check by going to each one and reloading the page to see whether it is from that page.

Why does firefox open after i uninstalled it and installed google chrome

i uninstalled firefox, then installed google chrome. often i will be on chrome and firefox opens a window with porn sites and multiple tabs. how is this possible after being uninstalled. and this only happens on my girlfriends desktop. On mine i dont get anything like that.

First of all you need to run some malware scans, it sounds like the computer has been infected. Try running several malware scanners, you can use any of the following:
* [http://www.malwarebytes.org/mbam.php Malwarebytes]
* [http://www.superantispyware.com/ SUPERAntiSpyware]
* [http://www.lavasoft.com/products/ad_aware_free.php Lavasoft Ad-Aware]
* [http://www.microsoft.com/windows/products/winfamily/defender/default.mspx Windows Defender] (If you use Microsoft Security Essentials then you will not need to use Windows Defender)
As for Firefox appearing, that implies it has not been uninstalled. The [http://kb.mozillazine.org/Uninstalling_Firefox uninstalling Firefox] article shows how to manually remove Firefox if the uninstaller failed.

Why does Firefox open another Start Page tab everytime I hit the home key (which take me to my homepage on the current tab)?

When I hit the home key Firefox takes me back to my homepage (AOL) but also opens up a new Mozilla Firefox Start Page tab. I end up with a whole bunch of unwanted tabs.
== This happened ==
Every time Firefox opened
== always

Hello Ginna.
Please check the following:
Click on '''Tools> Options'''.
Then click on '''General'''.
Now, it should say: '''http://aol.com/''' (or similar), but please check if it has anything after that. For example, if there is a '''|''' after it, that tells FF to open up 2 pages when you hit the home button: AOL and the other page, which in this case is a blank page.
If you see a '''|''' in there, go ahead and adjust it or remove it, if you'd like. If not, please report back here and let me know!

Why does firefox open up more then one page when I login

After upgrading to Firefox 5, when I open Firefox it opens about 15 to 20 pages and I have to close the pages before it will let me continue. Why is this happening?

But there aren't any symbols. It's just set to http://www.yahoo.com
And every time I open Firefox, it opens with 3 Tabs, one of which IS Yahoo but the other 2 a regarding plug ins being successfully updated. I've even gone as far as to uninstall those plug ins and it still opens with 3. About ready to uninstall Firefox and stay with IE

Why does firefox opens new window/tab when i click on a link

if I click any link in Firefox it will open another blank window in addition to the link clicked, blank window opens on top. how do I stop this

If a website codes its links to open in a new window, you can divert that to a new tab.
The basic setting for this is here:
"3-bar" menu button (or Tools menu) > Options > Tabs
The first checkbox: "Open new windows in a new tab instead"
In some cases, a website uses a script to launch a new window with special features, such as a set height/width, or with one or more toolbars removed. To avoid breaking sites that create dialog boxes this way, Firefox does not normally divert this kind of window to a new tab. However, if you wanted to send these to a tab as well, there is a hidden setting you can change. (See: https://support.mozilla.org/questions/1035103#answer-662627])
If Firefox is sending ALL links to new windows or new tabs, you might have an extension like Tab Mix Plus or Tab Utilities which changes the built-in tab handling features. You would need to explore their settings to get it just the way you want it.

Why does Firefox open in a new window with some sites? I hate this.

In some instances, a new browser opens with my homepage when typing in certain websites. I didn't have this problem before upgrading to 7. I hate this.

That are probably JavaScript window.open() calls that specify window dimensions.
You can divert those to a new tab.

I just got Windows 7 - and it's on a new computer, so there are no old settings that need to be 'fixed'. Why does Firefox open "squished"? It doesn't fill the whole page. It's margins are about 4 inches in, on both the right and the left.

I have no other details to add, that I know of. Firefox just does not fill the entire page.

1) ensure iTunes is authorized for your iTunes store account(s)
2) connect your device and right-click or control-click it in the iTunes Source list, then choose transfer purchases from the shortcut menu that appears.
3) sync the device
iTunes will wipe the iPhone but, since you transferred your purchases in the previous step, your content will be in your library and you can re-populate the iPhone with it.
above works for purchases from the iTunes store. for everything else, check out this post by Zevoneer.

Why does Firefox open links in a blank tab?

Sometimes when I click on a link, the page loads. However, it shows up blank and the tab only shows the URL. For example, if I type in www.google.com in the Awesome Bar, a tab with http://www.google.com will appear as the name but the page itself loads blank. I do not know why this keeps happening. I have tried disabling Noscript and Adblock Plus and it still happens.

I ran Firefox in Safe Mode with all extensions turned off. When I clicked this link ( http://www.4shared.com/audio/GhZf3rUy/Puzzle_Fighter_Arranged_-_Stag.html) in this Youtube video:
http://www.youtube.com/watch?v=-haPlhz1ZAE&feature=related, I got the following image:
http://img508.imageshack.us/img508/2238/brokenff.jpg
Note there is another tab which has the same kind of title as the tab which currently has focus.
Update: I am now running in Safe Mode using the default theme. I'm going to try and replicate this situation (not sure if it's a bug) again.
Update 2: The same thing happened again with the default theme. What I've noticed is that Firefox will display the page as blank even if the link works. I'm not sure why this happens.
