Why is firefox sending so many outbound connections, close to 200.

When I first open Firefox, everything slows down and/or stops. When I check my firewall, it occasionally shows as many as 215 outgoing connections, as much as 95% of which are from Firefox. The OS is Win Vista Home Edition. The firewall is Comodo.

Hi,
Please check if this repeats in [https://support.mozilla.com/en-US/kb/Safe%20Mode Safe Mode.] Safe Mode disables the installed extensions and plugins in '''Tools''' ('''Alt''' + '''T''') > '''Add-ons'''.
Please also note that Firefox may open multiple connections per server, so having many tabs open could also be a reason. Firefox may also prefetch content from links in a page while idle.

Why does Firefox send scary warning "This Connection is Untrusted" for URLs that I know are OK?

Example: I try to log on to renew automobile registration at www.DMV.state.pa.us or other innocuous locations and I receive that scary warning. So I log in on Explorer on my PC and the website works OK. Am I doing something wrong?

as far as I know, you are not doing anything wrong. I get the same message for some government managed pages. I believe it has to do with who furnishes their certificates.
Firefox has a article that explains security certificates here:

Why does firefox stop loading then when i close it and try to open it up again I keep getting this message:Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system

Firefox will just stop loading/ connecting to the internet. The gray circle will just continually move but it never turns green to load the pages. I know it's not my internet because my internet explorer works just fine while this is happening to firefox. So I close firefox and then try to re open it but I get the message: Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system. So I wait a little bit then try and re open it and still get the same message. I then go into my windows task manager and try and end the firefox proccess but it won't end. So I restart my computer and firefox eventually starts acting up again.

For possible causes of this error, and how to troubleshoot it see [[Firefox is already running but is not responding]].

After applying cure, why does Firefox still, stubbornly, make unrequested connections?

After meticulous care to follow the guides on the support link titled "Firefox makes unrequested connections" [... http://support.mozilla.com/en-US/kb/Firefox+makes+unrequested+connections?s=firefox+is+seeking+unrequested+website&as=s ...], Firefox is still trying to contact obscure sights like:
iy-in-f104.1e100.net 
yw-in-f121.1e100.net 
iy-in-f103.1e100.net 
The above resolve to google. Yet I am not going to google and do not use the default search provided by Mozilla or Firefox browser. What is causing this browser to go to google, even after I thought I had, several times, performed the cure to stop it from accessing un-requested websites in the back-ground?
Firefox is acting mischievously, because it does this without being told to do that, and after I have asked it to stop. When it does go, it does not post any information on my browser telling me what it is doing.
After much effort to get it to stop, I consider this to be a nuisance that it is stubborn and acts on a hidden code to defeat my requests and actions trying to prevent it. This is the same behavior as malware and viruses that dial back to a location, do not announce what it is doing, and will not stop, after many hours of effort trying to instruct (reverse coding to get) it to stop.
I have now spent about 5-6 hours trying to figure what is the cause, and as such, it can be categorized as time wasted as when dealing with malware, that does not inform the end user what it is going to do prior to installation nor announce it, as it is being done, in the background.
Sometimes Firefox performs a hiccup and tries to change my update settings back to a condition of seeking to update itself or update its addons or updates its search (all options under the updates tab). Furthermore, Firefox has acted on routine of once or twice a month to change from "asking me what I want to do with updates," to "install automatically." Many times in the last 6 months I have seen it was trying to executive a program of updating, when it was not authorized to do such a thing, and was there to cancel this execution-sequence, if not too late. In this 6 to 7 instances, I have been prompted to go back and observe if Firefox is changing my settings by executing hidden code or back door code. In each instance all my update settings have been changed.
I have to go back inside the browser options, and deselect all the updates and also change from "install automatically" to "ask me what I want to do." This is even more curious because, such items were set to "false" via about:config as per instructions in the support link above. Have double checked addons, to make sure they are not trying to update.
In conclusion, this is obviously not a bug, as it is so deliberate and happens on some routine. It seems to a happen irregardless of what "version" or update is being used; including many updated versions since Jan 2010. Also what ever it is, an execution of code or backdoor to trigger same, it is not described in the readme file that comes with firefox.
So how about the programmers of Firefox stop belittling us by employing the same gimmicks as malware and tell us what is up with this: seeking unrequested websites and not announcing that it is occurring, when it is occurring.

Why does firefox crash when the internet connection is lost?

We have been having trouble with our internet connection recently and firefox crashes whenever the connection is lost, but this didn't used to happen, so I was wondering why this was happening.

If there is any intermittent issues or connection is lost you will revert to the menu, regardless. The 'apps' are fed via server and there is nothing stored on the unit, it simply caches when you are online.
As for the initial wait time. That could be due to ISP throttling, interference, using another DNS
Note: This is a user forum, there is no service provided here by Apple. If you wish to get official tech support you need to contact them.

Why will Firefox will not open when connecting via Remote Desktop?

I have Firefox v. 6.0 or 7.0 installed on a Win 7 machine. It works fine locally, but when I connect to the machine via Remote Desktop it will not start.

Make sure that the pref dom.storage.enabled is set to true on the about:config page.
* http://kb.mozillazine.org/Dom.storage.enabled
* https://developer.mozilla.org/en/dom/storage (Storage location and clearing the data)
To open the about:config page, type about:config in the location (address) bar and press the "Enter" key, just like you type the url of a website to open a website. 
If you see a warning then you can confirm that you want to access that page.

Why does Firefox use an unsigned server connection request before conneting to internet?

<pre>Locking duplicate thread.
Please continue here: [[/questions/979016]]
</pre>
When an application wants to make a connection to a server for internet or updates it presents a signed server connection request. Recently, in order to get Firefox to connect to the internet, I have to approve unsigned server connection requests even though I know unsigned requests are open to abuse from hackers. How can I get Firefox and other applications from reliable suppliers to issue SIGNED server connection request? Please help. Regards.

Why would Firefox give me an "Untrusted Connection" error where IE and Chrome don't?

I get an Untrustead connection error in Firefox when accessing https://eponline.mom.gov.sg/epol/. Both IE and Chrome trust the site. What's different about Firefox?

This Connection Is Untrusted error message may appear when trying to visit secure (https) websites in Firefox.
It Appears in Google Chrome also..

Why does Firefox have so many unresposive script errors?

Firefox 22.0 (on Mac) seems to be a dog. It continually stops responding and gives so many "A script on this page may be busy, or it may have stopped responding" errors.
Either Facebook have done something, or there is an incompatibility between Flash, Firefox and Facebook or something. (Flash 11.7.700.225)
I have had this before with other Firefox builds - but this time it is occurring multiple times each time I am on Facebook
Thinking of trying Chrome if this keeps up - although I am reluctant to hand yet even more privacy info over to Google.
The only plugin I use is Flash. I run the default theme, and the only add-ons I have are Adblock Plus 2.2.4, Adblock Plus Pop-up Add-on 0.8 and the English (Australian) Dictionary 2.1.2
I wish each so-called 'security upgrade' came with a message that 'this version is a dog' - it is not only causing issues it is not compatible and has disable my "Easy Youtube Video Downloader 6.8"
As per the Mozilla Help I have disabled "hardware acceleration" and also changed the value for "dom.max_script_run_time" to 20 - neither helped in any way.
Far from happy Mozilla

Thank you for your "copy and paste" reply. It is very obvious that you did NOT read my original post.
If you had you would have noticed:
a) I stated: "I run the default theme"
and that
b)I stated: "I have disabled "hardware acceleration""
c)I stated: "changed the value for "dom.max_script_run_time" to 20 "
(both of which are in response to the linked help article that you recommended - and neither of which did any good)
d) I also stated: "The only plugin I use is Flash"
(which is the latest up-to-date version and if Firefox cannot run with Flash it is of no use as a browser)
I will try "Safe Mode" and post how that works after browsing Facebook - but it should not be necessary to do this.
I had reported similar issues with Firefox two or three builds back (Firefox 19.0.2) then the issue was fixed for a couple of builds - and now with the release of Firefox 22.0 (on Mac) it is as bad or worse than ever.

Why does Firefox create so many temp files in cache? Once it filled up entire free HD space (46GB)?

Every now & then, Firefox will have created zillions of directories and files in Cache within the directory for a Firefox profile. The directories are called 0 (zero) through F (using the hex numbers as names, i.e.g), and within each of these will be more directories (with two digit hex names). The last time this happened (1 week ago), these directories ate up ALL of my free hard drive space (about 46 GB worth).
Why does this happen? Can I stop it from happening? If so, how?
THanks.

Yes it should be easy to reset.
It may be set from
* '''Options -> | Advanced | -> |Network| -> Cached Web Content''' [] Override automatic cache management
* see [[#w_cached-web-content]]'''_cached-web-content'''
Presumably your automatic setting has been overridden and the box needs unchecking.
I know Firefox does split the cache up like that IIRC it allows the cache to be faster and solves fragmentation issues.
46GB That seems a surprising amount and can not be right if it eats up all hard disk space. I also know that the file places.sqlite is a variable size, but that is based on the system in use.
The ordinary HTTP cache is also set presumably intelligently, but can be over-ridden by the user
This has some background info
* https://developer.mozilla.org/en-US/docs/HTTP_Caching_FAQ
*http://kb.mozillazine.org/Browser.cache.disk.capacity
My own settings as viewed in about:support are
browser.cache.disk.capacity 358400
browser.cache.disk.smart_size_cached_value 266240
browser.cache.disk.smart_size.first_run false
My cache use is limited to about 350MB

Why does firefox send these two messages several times a day?

Hello @susan649,
Welcome to the HP forums.
I understand that you are concerned about the amount of updates being sent to your Photosmart 6520.
I would like to help.
That is actually a lot more then normal. One every few weeks sure. four or more a day? Nope, not normal.
Perhaps the same update is not updating properly so it tries again later.
I would try setting a manual DNS.
The following post by happytohelp01 has steps and screen shots to perform this.
Efax 7510 still won't work after turning off/on ePrint several times
The screen shots are for an Photosmart 7510, but the steps are the same.
For the Manual Preferred DNS Server please use 8.8.8.8 and for the Alternate Preferred DNS server please use 8.8.4.4. These are Google’s public DNS servers. If you find that those DNS settings don’t work, some customers have had success using the Level3 DNS servers. I have included About.com’s Free & Public DNS Servers.
If your printer is still doing an abnormal amount of updates, please call our Cloud Services at 855-785-2777.

Why does Firefox send me back a few pages when I attempt to type into a text box???

I am sick and tired of this insane bug. It affects me on a daily basis. 20% of the time I attempt to type anything into any text box, for every keypress, Firefox will treat them as requests to 'go back' and it launches me several pages backwards through my browsing history in the tab. I then I have to skip forward and attempt filling it in again. It usually works after 1-2 attempts but like i said this is happening 20% of the time on text input forms, especially FARK.com.
== This happened ==
A few times a week
== Year or two ago

Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
See [[Troubleshooting extensions and themes]] and [[Troubleshooting plugins]]
If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
You can use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.
You have to close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

Why in Firefox 9 are many bookmark icons missing? (Mac OSX Leopard)

After the 9.0 update most all of the icons in the bookmarks lists disappeared. Others have a dotted line box in place of solid box. What gives?

Hi unclesuds,
You should take a look at [https://support.mozilla.org/kb/latest-firefox-issues#os=mac&browser=fx9 this article] that discusses some of the issues with the latest build of Firefox.
There is some information in there that should help you to resolve your issue. Luckily, it is a very easy fix.
Hopefully this helps!
