Not knowing anything about Sync but enthusiastic about its advantages, I followed the directions for setting up a Sync account in my new laptop. Then realized I should have started with my main computer which has all the data that I want to transfer to the new one. However, Firefox won't let me set up the sync account in my main computer because it says I already have an account. It gave me a code to link the main computer to the new one, and I did this. Now I'm afraid to sync for fear that this will wipe out the info in my main computer rather than transferring it to the new one. Is this true, and if so, how can I start over and get Firefox to let me establish the sync account in my main computer?

mistakenly i uninstalled my firefox browser from my PC , But i saved my bookmarks, passwords, settings, history, add-ons, and tabs with Firefox sync setting. how i could recover [or] get back all of my sync data(i.e bookmarks, passwords, settings, history, add-ons, and tabs) to my latest installed firefox browser. thanking you . help me as soon as possible..........

I started my computer this morning and everything seemed normal, yet once I got on youtube, every video i tried to watch wouldn't play properly, even though yesterday things were fine, and I've never encountered this problem before.. I hadn't updated, installed or otherwise changed anything between the two days and everything else works just fine.. Whenever i start a video the sound chops up and skips/lags like it can't keep up.. It's hard to describe.. Kinda like if one listens to a CD with lots of scratches... I initially assumed that it was a Flash Player issue.. But after updating both Flash Player and Firefox to the latest versions the problem still persists.. I now assume it is a Firefox issue, as I have tried viewing the videos in other browsers, and they play just fine.. I have no idea what is causing it.. And I would appreciate any help or solutions you could give me.. I'm also not that big of a computer expert, so please forgive me for anything seemingly obvious I might have overlooked.. Thanks in advance..

Hi at 1632 GMT/UTC on Friday 15th March 2013

I have 2 new machines. When I go through the sync procedure and try both options Create an Account or I Have an Account my e-mail address shows already in use (perhaps off a previous machine.) How do I delete an account in Firefox records and start right at the beginning creating a new account please

I have already been here. https://support.mozilla.org/en-US/kb/how-do-i-set-up-firefox-sync

Thanks pingu70

I cannot sync my Firefox 18 desktop with iPad or iPhone browsers. I have tried everything suggested on the Web and have tried safe mode as well. When I enter the three-line synch code, I get a sync failure. I have deleted my account and then set up a new account without success. Manage Account does not appear in the options sync tab. How do I manage my account to get the recovery key?

I’ve spent hours on this and am considering using Chrome as my regular browser since I have no trouble syncing Chrome with apps. Help appreciated.

my PC keeps trying to download files from chrome. I am told by Trend Micro that this is a Mozilla download and they do not know how to stop it.

Basically what I want is for these download attempts to stop as I do not want Chrome on my PC.

So can you say how to stop it or give me a batch file that will stop it.

It happens just about every three or four minutes and I am frankly fed up with it so if you want me to keep using Firefox and Thunderbird please tell me how to stop it.

After the last update of Firefox (to version 16.0.2) I get random words on a page of a site that are underlined. These underlined words link to sites where I can win stuff. When I put my mouse cursor on them I see a text saying: Click to continue > by CouponDropDown. I don't want this, how do I turn it off?

Initially, I did not request ask.com to become the default search engine and I did not ignore the box making the request. I have made the following efforts to return to google as default: Uninstalled ask.com and its automatic update, disabled all add-ons (including those that did not apply), checked extensions anything that pertained to ask.com (nothing was there), re-downloaded the latest version of Firefox, searched about:config for ask.com and reset it to default (google). On the Start Page the ask.com logo is still in the URL and a test search in the box under the logo yields ask.com results rather than google. Any additional recommendations would be helpful. At this point, I am considering the following: (1) restoring my computer to an earlier date; (2) reseting or removing firefox and reinstalling it; and (3) removing AVIRA.

I recently updated to Firefox 15.0.1, and I'm having a lot of trouble with it constantly freezing. This doesn't happen on any one website and is very random in occurrence. I have already tried running in safe mode and updated flash, and I'm still having the problem. After a few seconds, it may start responding again however, most of the time it continues to hang. In order to close Firefox when this happens, I have to open task manager and end the process because nothing in the browser responds. This has become very annoying, and I would appreciate any help I can get to solve the issue. Thanks!

UPDATE: I've noticed that the freezing seems to happen every time I check my email (Yahoo & Gmail), and when I'm on Pandora. It still occurs randomly at other times, but I noticed it's very consistent with these sites.

Ok, here's the deal.

After long use Firefox starts to lag like crazy with Flash. And... It doesn't seem to be a problem with Flash. It's more likely that the browser itself what is causing the issue.

After I use Firefox for some time Flash starts lagging badly. BUT! This happens only if I have my Firefox window active. If I open the Task Manager on top of Firefox window, Flash stops lagging as if Harry Porter himself cast a spell with his magic stick making everything work like a charm.

I made a small video showcasing the bug: https://www.dropbox.com/s/l2c5pbn1xwy58dc/12-11-2012%2019-07-15.avi

- The bug still appears even in Safe Mode (all addons disabled).

- With hardware acceleration disabled in Flash bug still remains.

- With Chrome and other browsers everything works fine.

- The bug will go away after restart - and then will start to appear after Firefox is in use for some time.

- Normally it re-appears after I close my laptop's lid forcing it to go to sleep mode. After it wakes up - the bug is there.

- There was no such a bug in the past - it started to appear as new Firefox versions were released - don't know the exact version but I assume it all started from version 14 or 15.

Any thoughts?

when i open firefox it displays a blank white screen with the words "no site configured at this address". what does this mean and how can i fix this? i tried reinstalling firefox and cleared cache. it used to display my yahoo homepage. it wont now unless i type in to address bar.

Firefox has become very slow. It takes long time to load any website.I have reinstalled FF but the problem remain. As a test I downloaded Chrome and it is much faster. But I like FF and would be very glad if you can help me fix this problem.

I've almost completely removed search.babylon, but cannot get the last bits of it to leave. Search.babylon remains the default search engine of the about:home page for firefox, and no mater how many times I reset the babylon entries in about:config, they just go back babylon afterwards.

I know that there are a lot of people having problems with Babylon, and lots of answers. I've tried every suggestion I could find, without success.

The things I've tried:

1. Babylon toolbar was never in my firefox extensions, so there's nothing to remove there. 2. I've uninstalled Babylon via the windows control panel. 3. I searched the entire C drive for any file containing the word babylon and deleted both the files and the containing folders. 4. I've removed search.babylon from my "manage search engines" list. 5. I've reset my home page. 6. I've reset every result containing "babylon" in about:config about a dozen times. 7. In the web developer scratchpad I executed "javascript:{localStorage["search-engine"]="{\"name\":\"Google\",\"searchUrl\":\"http://www.google.com/search?q=_searchTerms_&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a\"}";void(0);}" 8. Thoughout this process I've restarted firefox countless times.

Nevertheless, whenever I open a new tab or page, and try and use the search on about:home (the default mozilla home page, with the firefox logo in the center and "Downloads, bookmarks, history, addons, sync, settings" at the bottom), I'm taken to search.babylon.com

I am using Mac OS X Version 10.7.4. I am also running Firefox version 14.0.1. I am prompted to update to version 15, but when trying to update, the updating window hangs up for hours and never gets past "connecting to server." I have tried to install version 15 and trash my last version however I get another pop-up box that states something like "cannot complete due to some items being skipped." I followed the directions to troubleshoot (File > Get Info, then make sure all items are unlocked) but this still doesn't solve my problem. Can anyone offer some advice? Please?

Previously when I typed one word or more in the address bar, it would do a google search. Now when I enter one word and press enter it takes me to a while page with the following message on it:

502 Bad Gateway nginx/1.3.7

It does the google search when I type more than one word.
