Firefox has created thousands of bookmarks, sync is slow, FF is slow, FF freezes

I can't delete bookmarks by the traditional means since it freezes FF.
I need to mass delete these bookmarks AND I need to purge my new FF Sync account. How can I do that? The old sync allowed you to purch bookmarks in the cloud.
The large amount of bookmarks are all "Mozilla Firefox" folders. It's impossible to delete them all.
I use sync wth 3 computers (2 offices, 1 noteboook), 3 iOS and 1 Android device. It's a nightmare!

This has helped a lot with a lot more resources. The add on I ultimately used successfully was the SQLite Manager. I went in and did a mass delete of all the duplicate bookmarks. There were over 10000 of them that caused problems with the freezing and synch. I could not use the "Show your bookmarks" button on FF because of the large number.
All of the duplicated bookmarks were "Mozilla Support" folders. I think there is a larger problem with sync. I have 3 computers and 4 devices that sync and I suspect that when there are updates, whether it's FF, Windows OS updates, re-installs or anything, the Places file grows over time. This problem became most apparent when moving to the new sync. Due to geography I couldn't put all my devices on the new sync simultaneously. Maybe it's something about the old and new sync when devices are split? Very strange.

Why Firefox has all these problems?

First, I updated Firefox to the latest version but I have noticed that Firefox has a lot of problems and relatively slow to browse sites and also slow to respond, however, most of the Firefox browser crashes all the time, causing the system to freeze ... For the first time get a problem with RealPlayer Browser Record Plugin?

A bookmark folder with thousands of bookmarks I've saved over many years has disappeared and I can't find it in the bookmarks menu or recycle bin

I've also tried doing a restore by choosing the "Show all bookmarks" "Import and backup" "Restore" to a day earlier and the folder still didn't show up. When I tried to do this again using one of the many earlier dates I had seen that were available the first time, now only today's date is available. I've done searches and no folder by the name of the missing folder appears to be on my computer. I'm sure I didn't delete it and nobody else has access to my computer. I've used Firefox for many years and I've never seen this problem. I've checked in all the other bookmark folders and it's not in any of them. If I can't resore or find this folder, years of work and thousands of bookmarks will be lost. Any help or suggestions anybody might have would be greatly appreciated. Thanks in advance.

Immediately backup your whole Firefox profile.
* [[Back up and restore information in Firefox profiles]]
You will have over written your bookmarks database and it may be difficult to recover. You may at least have backups of bookmarks that are still usable but that is why you must back up the profile.
Create a new additional test profile using the profile manager. Next test the bookmarks from your backup restoring them into Firefox whilst open with and using the new test profile. If one of those backups works you should be able to restore that into your ordinary Firefox profile.
You may need to delete the database places.sqlite to get working bookmarks. But rename it rather than delete it as it is then easier to reverse. Note if you do need to delete the places database you will lose your Firefox History.
There is an alternative strategy but again ensue the profile is backedup. And in this case also backup separately places.sqlite before any recovery attempt.
The Windows OS should try to keep previous copies of Files and it is possible that you will have a usable previous copy of ''places.sqlite'' that may be recovered by options available from right clicking the current version.

All add-ons has been disappeared and even sync option didn't retrieve any of my password or bookmark

All of my add-ons and bookmarks has been disappeared!
I've tried to make "synch now" to retrieve them however nothing was happened!!
How could I back-up them please?

I still see some active and inactive extensions listed in the System Details List.
Did you reinstall those?
The inactive extensions may be installed globally by other software and not in the Firefox profile folder.
You can check if there is a new profile created.

If there is an "Old Firefox Data" folder on the desktop then Firefox has been reset and your profile has been moved to the desktop.

I currently use an iPhone, an iPad, and a Mac computer for business. The three devices have Contacts Managers that sync with each other through both Google and through Mobile Me. Currently, this has created a mess of duplicate contacts. Please advise me on the steps necessary for removing these duplicates and establishing a syncing solution that doesn't regenerate the duplicates. There are several applications available that remove duplicates, but I am not sure which ones work or don't work. I want information on this, but most importantly I want to understand how to fix this problem permanently. Also, I read somewhere that Mac's new operating system, Lion, can help deal with duplicates. I don't have Lion, but I would be willing to get it, if this would fix the problem.

Had the same problem with 4 devices (two computers, an iPhone and an iPod). The solution is simple: open the Address Book application in your mac, ask it to locate duplicate entries (under one of the top menu items, "edit" I think), and then ask it to consolidate them: it took me all of three seconds after I figured it out: worked like a charm! PS: if you have more than one mac with unconected Address Books, repeating the operation in the second one may be a good idea.

The Java plugin has created a time unfriendly issue with my e-mail account, I can not open or send any e-mail without using this plugin, how can I eliminate this problem without dropping m. firefox?

A few days ago I tried to e-mail a friend, when I started A box came up and it required me to add a plugin..Java. I contacted my e-mail courier and microsoft, they told me that is was a plugin from Mozilla Firefox. Since then I must go through Java to send or open an e-mail... this is NOT to my satisfaction, it takes too long for all of this to open and if it is not cleared , I am dropping Mozilla and going elsewhere. Why has this occurred? Is this a result of the last update? If so can I delete the last update and continue on the other version?
== This happened ==
Every time Firefox opened
== last week

Sorry, I have no idea what you mean by '''"The Java plugin has created a time unfriendly issue with my e-mail account, I can not open or send any e-mail without using this plugin,"'''.
If you think your problem is caused by the Java plugin, you should visit the Java support forum for assistance.
http://forum.java.sun.com/index.jspa
If you could explain what you mean by '''"time unfriendly''' issue with my e-mail account", maybe we'll be able to help you solve that issue.
It might be helpful for us if we knew exactly which web-mail provider you are using. It seems strange to me that viewing or sending web-mail would actually "need" Java for operation, its more likely that some other item on the web page needs Java to run some advertising or other garbage that isn't a necessary part of the web-mail functionality you want to use.

TS2972 My computer crashed and the hard drive is no longer. I have purchased a new laptop but now have no access to my old itunes library. My laptop has created a new itunes account with NOTHING in it?? My Itouch has everything loaded but it wont sync

My computer crashed and the hard drive is no longer. I have purchased a new laptop but now have no access to my old itunes library. My laptop has created a new itunes account with NOTHING in it?? My Itouch has everything loaded but it wont sync with this itunes account....HELP

- Transfer iTunes purchases:
iTunes Store: Transferring purchases from your iOS device or iPod to a computer
- Transfer other music by using a third-party program like one of those discussed here:
newer copy
- Connect the iPod to the computer and make a backup by right clicking on the iPod under Devices in iTunes and select Back Up
- Restore the iPod from that backup
Note that the iPod backup that iTunes makes does not included synced media like apps and music.

I can't get firefox to open. Try creating another profile as suggested in another answer, and it says that firefox has crashed, how do I get firefox working?

I had to restore my computer to a previous restore point. When I tried opening firefox 4.0, nothing happened. Frustrated, I tried removing the program, but ran into the same problem: nothing happened. I went to Processes in Windows Task Manager, and firefox.exe was not running. Tried using the suggestions to create another profile, and entering the command into run brought up an error saying that firefox has crashed.

OK - undo the changes you made to DEP.
Open Firefox - take a screenshot of any message that appears and post back here

On Mac and Firefox 3.6.6., I can't create a new folder in organize bookmarks because it is grey. I used to be able to do this. How do I create a new bookmark?

For what it's worth, here's the bug on this: https://github.com/adobe/brackets/issues/1577. It will be fixed later when we move the Getting Started files out of the install folder.

I recently updated my browser. A message then came up, saying that firefox would create a folder with my old bookmarks. But I can't find my bookmarks in it?

I recently updated my browser. A message then came up, saying that firefox would create a folder which would include my old bookmarks. But I can't find my bookmarks in it?

I'm not familiar with that message...
Are you bookmarks still intact and working normally?
Is there an Old Firefox Data folder on your desktop by any change? If the Firefox "Reset" feature runs, that folder should be created.

Does Firefox has this option (which I may not know) to click on my bookmark, link, etc. where to open a new tab without doing this right-click, it is aggravating?

Hello, I would like to use Firefox as my default browser, but the reason I still use the old Netscape Navigator is that that clicking on my bookmarks Firefox is not opening new tab. Does Firefox has this option (which I may not know) to click on my bookmark, link, etc. where to open a new tab without doing this right-click, it is aggravating?

Iphone 4s - my bookmarks synced with Firefox Home just fine, but none of my bookmarks showing on Safari. Help!

iphone 4s - my bookmarks synced within Firefox Home just fine, but none of my bookmarks are showing on my phone's Safari. Help!

Hi,
You will need to use Firefox Home to launch those URLs.
I hope this clarifies your situation..

New Firefox seems to be missing the ability to create a new bookmark folder--any help is appreciated.

I just updated to the new Firefox, and now, when I try to create a new bookmark folder, the option is no longer there (I can see all my old folders, but the option "New folder," which used to be on the bottom of the drop-down menu, is gone. Nor do I see it anywhere else.

Hi, Matt,
I really appreciate the speedy response. I did go into the Bookmarks Folder of the Knowledge Base, but actually don't see any article (I skimmed each of them) that deals with folders. The frustrating thing is that I've been able to create bookmark folders with no problem up until I updated Firefox to the latest version yesterday. Now the option to create a new folder does not appear.
I'm enclosing a screen shot of the dialog box; previously, when adding a bookmark, an option to "create folder" would appear at the lower left of this box.
I'm sorry if I'm missing something obvious. I really appreciate your time.
Best,
Kathy
