Server not found when switching from 4g to wifi and vice versa.

I've had this issue for a while across multiple phones and multiple versions of Firefox for Android, and it does not happen with any other browser (which is upsetting). Whenever I am surfing the web and have multiple tabs open, and I switch from 4g to wifi or vice versa, I always get a "Server not found" error on both existing tabs and new tabs. This is an annoying issue that I am surprised to see hasn't been fixed. The only way I've been able to fix it is to quit and relaunch the app. I have tried removing plug-ins and reinstalling, but it has not helped.
Anything I could do to alleviate the issue?

Hi scruffy90:
You wrote "LG G2 and Samsung Galaxy Note 3. Both on Android 4.4.2 Firefox for Android Ver. 35.0.1 "
I just tried switching between HSPA+ aka 3G and WiFi on a Galaxy S5 running Android 5 and have had no issues but I think this may have been an issue in the past (I did a search for a bug in bugzilla.mozilla.org but couldn't find anything).
Are there any other details you could provide that could help us debug?
e.g.
# Are you using a proxy?
# Who is your WiFi provider?
# Have you tried other WiFi (e.g. the Wifi both at home and work)
Cheers!

Hello Roland,
No proxy on the phone or wi-fi network.
My ISP is Time Warner, but I supply my own router (Linksys e4200)
And this happens on every wi-fi network, at home and away from home.

Problem loading safari webpage after switch from EDGE to 3G and vice versa.

ok, very simple question
i'm on edge, i want to go on safari, so i enable 3G. after that i go on safari and try to open a webpage. even after the 3G icon displays on top, it still takes a very long time before the webpage starts to load. Sometimes i get a message saying Safari could not open the page because the server stopped responding. IS THIS NORMAL?
also if im on 3G and switch down to EDGE and then open a page in safari i get a message saying Could not activate cellular data network, even though the page loads anyway. IS THAT NORMAL?
Message was edited by: Stevendo

are you on 4.0.1?
if so then this of course is not normal but it is also happening to me
ill be at home and have 3G on 4 bars and i try to load a page on safari and nothing happens, then i switch it to edge and it connects, but like u when switching from 3G to edge i get those messages.. also i noticed that this only happended after i updated to 4.0.1 and i NEVER got these problems b4 on 4.0 and to make things worse.. in order for my 3G data to work i have to make a phone call, hang up, then ill get connectivity on 3G..
so the fix... i dont kno??
but im suffering like u...

Logic error in rotating a bot towards a target (switch from -180 to 180 and vice versa causes error)

Hi,
I am making a Bot class. This function rotateTo makes the bot rotate towards some coordinates, xTarget and yTarget.
There are two targetRadians lines because it is easier to read for me.
The target radians shows the angle of the target from the bot where the bot angle is this.angleRot.
if the bot-angle minus the target-angle (it says in radians but is actually in degrees) is less than 0 it turns right and if it is greater than or equal to 0 then it turns left.
public function rotateTo(xTarget, yTarget):Void {
                    targetRadians = Math.atan2(yTarget-this.yPos, xTarget-this.xPos);
                    targetRadians = Math.round(radiansToDegrees(targetRadians));
                    trace(targetRadians);
                              if (this.angleRot-targetRadians<0) {
                                        turnBot(5);
                              } else {
                                        turnBot(-5);
This basically works. The bot rotates towards the target at 5 degrees per frame.
The angle setup is that if the target x, y is below the bot x, y, the target angle is about 90, if it's to the right its about 0, if its above it's about -90 but as the angle is decreased to -180 from above to the left of the bot, when it goes below the bot (and to the left) the target angle switches to 180.
So something like: with the bot in the middle and the target being located at one of the numbers;
          -90
-180               -1
180               1
           90
The fact the target angle switches from -180 to 180 or 180 to -180 confuses the bot and the bot decides to turn ALL the way the opposite direction BECAUSE;
if the bot angle is 160 and target angle is 175, the bot angle increases because target is greater than bot angle. If the target angle changes to -180, bot angle decreases even though it's more efficient to change from 160 to -180 through increasing the bot angle as at 180 it changes to -180. I just cannot work out the logic to use to make this work though.
Any suggestions? Thanks.

Hey I got it to work finally:
public function rotateTo(xTarget, yTarget):Void {
                    targetRotation = Math.atan2((yTarget-this.yPos), xTarget-this.xPos)*180/Math.PI;
                  if (this.angleRot-targetRotation>180) {
                              this.angleRot -= 360;
                    } else if (this.angleRot-targetRotation<-180) {
                              this.angleRot += 360;
                    if (this.angleRot-targetRotation<0) {
                              turnBot(5);
                    } else {
                              turnBot(-5);
so basically I added a couple of if statements before the main business.... I don't really have a coherent explanation for the fix but it works!

How to change view in iPhone from vertical to horizon and vice versa?

How to change view in iPhone from vertical to horizon and vice versa?

Not all applications will go from Portrait to Landscape. Changing just requires you to turn the device. However, if you have the orientation lock activated, then it will not change to landscape. To check, look in the status bar and see if you can see a small lock shaped icon near the battery icon. If you do, then orientation lock is activated. To turn it off, swipe upwards from the bottom of the iPhone screen to bring up Control Center. The orientation lock is the last icon on the top row to the right. Tap on it to turn it off. White is on, black is off.

Server not found when Windows wakes up

When I wake up my Windows 7 desktop machine Firefox 7 always shows "server not found" errors for websites that continuously update, like huffingtonpost or drudgereport.
Clicking on "try again" always works fine, but I'd like to know how to set things so it would happen automatically. This started with Firefox 4.0. before that there was no problem.

It is possible the firewall hasn't completely restarted since the PC is waking up from sleep mode, but I would still blame Firefox. It should allow for this possibility just after sleep mode has ended instead of putting up a dialog box I have to click manually to fix the problem. Other browsers (Internet Explorer) don't have this problem.
But if there is a Firefox option along the lines of "wake up last after sleep mode ends" that I don't have set properly I'd like to know about it.

SharePoint link says "Page not found" when clicked from an e-mail

I have a published page that opens if I copy and paste the link on the address bar but redirects to "Page not found" if clicked on directly. It works fine if I navigate through the website to the page but if I copy the url from the same page and
e-mail it someone and they click on it, it takes them to the default page not found. I have checked every image and attached document on the page and all are approved/published.

Can you copy the text of the URL that is present in the email as well as the URL itself when navigating to the page directly? My suspicion would be an encoding issue with the URL.

Firefox is showing "Server not found" when Fedora 14 NetworkManger is detecting ppp connection through wireless broadband modem

Hi,
I am using Wireless broadband modem. Network manager is detecting the modem and successfully acquring an ip through ppp0. But Firefox is showing "Server not found". I have found that /etc/resolv.conf is updated properly. And ping or nslookup on some url like www.google.com is working from terminal. So it seems either firefox is not able to use DNS or ppp connection. I have also tried by disabling eth or lo. But of no use.

See this thread: here.
However, please don't use 192.168.0.2 for the router but 192.168.137.2 instead. Home sharing uses 192.168.137.1 on the sharing computer instead of 192.168.0.1 as it was in earlier Windows versions.
To make the change, unplug the WRT from your network. Wire your second computer to a LAN port of the WRT.
Open the web interface at http://192.168.1.1/
On the main setup page, change the LAN IP address from 192.168.1.1 to 192.168.137.2.
On the same page, disable the DHCP server.
Save settings.
Unplug the computer. Now wire one of the numbered LAN ports of the WRT to your home sharing computer.
That's it.

When i load a page i get "server not found", when i click retry it loads properly, what can i do to have firefox load page first time

When i load a page it often tells me "server not found". When i click on retry most of the time it works. How do i fix it so that it works the first time.
== This happened ==
Every time Firefox opened
== a couple months ago

You either have an extension that causes that issue or some security software (firewall) is causing a delay.
See [[Troubleshooting extensions and themes]]
Also make sure that Firefox gets full unrestricted access to the internet.
See [[Firewalls]] and http://kb.mozillazine.org/Firewalls

Server not found when trying to access our credit union.

Our credit union address is part of our bookmarks. About half the time we get an error message that says "Server not found".
It says to check the address for typos, check the network connection or make sure that Firefox is permitted to access the web.

Switching from AM to PM or vice versa on manually recording feature

I was trying to record a morning show (AM) using the manual recording feature, but I was doing it in the evening (PM). I was able to enter the channel, choose the day then enter the start and stop times, EXCEPT for changing PM to AM. If you are setting up the schedule in the evening, that field always shows "PM" and there does not seem to be a way to change it to "AM". If you are setting up the recording in the morning, then that field shows "AM" and there does not seem to be a way to change it to "PM". Does anyone know how to change it from AM to PM or vice versa? I pressed every button on the remote and nothing worked.

After choosing your start time you should be able to click to the right to change from AM to PM or vice versa by using the up/down button. I just did it.

Formatting is off when opening Word docs in Pages and vice versa

I recently decided to switch from Windows to Mac and bought a MacBook. I used to use Word on my Windows computer and now when I open .doc or .docx files in Pages, the formatting is off, i.e. bullets, tabs, spacing, etc. This formatting problem also happens when other people use Word to open my files that I created in Pages and saved as a .doc. Is there some fix for this so that I don't have to reformat each document that was created in Word but that I now open in Pages?

For maximum compatibility I think you need to use Word for Mac or OpenOffice.

UCCX changing time variables from AM to PM and vice-versa

Hi all.
I have an extremely irritating issue that I'm hoping someone can shed some light on.
I'm currently making improvements to one of our contact centre scripts. We require to activate redirection on the fly quite often, and in the past I used a modified script with different time of day tests.Going forward I wanted to provide the ability for this to be activated and times set through the GUI.
So I made some variables as parameters, of note these are RedirectOperation (boolean), RedirectFrom (Time) and RedirectUntil(Time).
The flow is that if RedirectOperation is true, a time test is performed to dictate when we redirect - this is in the form of:
(T[now] >= RedirectFrom) && (T[now] <= RedirectUntil)
Now I know I can use T[now].before(xxx) etc but the operation itself isn't the issue, it does work perfectly fine this way, but the times change from AM <<>> PM under certain conditions.
To explain:
I set the default (on the script itself) RedirectFrom to "T[6:00:00 PM]" and RedirectUntil to "T[11:59:59 PM]".
When debugging the script, I can see that the system changes the times from PM to AM (under the variable list on CCX editor during a reactive debug) ! That's if I've not selected these parameters on the GUI. If however, I do select the parameters and still use the default values, when debugging, they stay as PM!!
This is surely a bug??
To try something else, I changed my time format to 24 hour clock - so 18:00:00 and 23:59:59 respectively. I can set these on the script itself, and if the parameters are unchecked and left at default, it works fine. However when I select the parameter and try to change the times to (for example) 19:00:00 and 22:59:59, the GUI spits an error saying:"* Please enter a valid date for the Date configurable variable." I can only assume there is a mismatch between what you're allowed to put into the script and what the GUI thinks you're allowed to.
But certainly the script surely should not be changing between AM and PM when a variable is left to default??
Any ideas would be greatly appreciated!
Thanks in advance.
Scotty

Replication of Custom Fields from CRM to ISU and Vice versa

Hi Experts,
We are working on adding Z fields on BP level. For this how does the replication of the values takes place from CRM to ISU or vice versa. What are the middleware enhancement we need to do in CRM side or in the ISU side. We would add the fields on web UI crm side by AET but at ISU side how we need to do that and how would the field values replicate in both the system.
A approach for adding BP custom fields in CRM and its interaction with ISU and vice versa would be appriciated.
Thanks,
Mayur

Excuse, you may enter more in detail?
I have created a custom field on BP using the AET would now like to replicate this custom field in BP also in ISU.
I can do all this using the EEWB, but I would avoid it, since, in ISU we already have custom fields on BP, I just can not link them with CRM.
