YouTube and Add-ons say version of Firefox is outdated

Both YouTube and newer Add-ons for firefox say that I am running an outdated version, specifically version 2.0.0.9. However, when I check for updates in the browser firefox says that I am running the current version. I have uninstalled and reinstalled version 3.6.6 from the Mozilla website multiple times to the same result.
== This happened ==
Every time Firefox opened
== Several weeks ago

Your User agent is wrong
1. In the Firefox Location Bar, Where you enter the address of web pages, enter '''about:config'''
2. A "This might void your warranty" warning may appear. Click "I'll be careful, I promise!"
3. In the '''Filter''' text box, enter '''general.usergent'''
4. For each of those general.useragent preferences, right click them and choose reset.
You should be okay now.

Certain sites and add-ons say I can't run because I am running 3.0, but I am not, am running current version 3.6. Why??

Happened when I tried to run Constant Contact recently, then again today when trying to load FF pop up block add-on

Not sure how often

You should always use beta test versions with a new and separate profile and keep the regular release so you can use that version in case of problems.
See http://kb.mozillazine.org/Profile_Manager
Firefox 4.0b1 is the first of the beta test release versions and still has a lot of bugs.
Such releases are meant for testing only so if bugs are found then they can get reported and fixed before the final 4.0 version gets released.
If you do not have experience with such test releases then you are better of with the latest Firefox 3.6.6 release.

After updating to Firefox 9 I have lost all my Bookmarks and Add ons

Firefox updated it's self to version 9.0.1. When I opened Firefox all my bookmarks and add ons where gone.
I have searched the help section with no help.

cor-el,
This turned out to be the root cause for my problem. Simply renamed the
places.sqlite.corrupt file to places.sqlite and my profile (including bookmarks) worked again. Thanks!
By the way, I first noticed that something was wrong with my _profile_ when, in addition to lost bookmarks, I noticed that I couldn't create _new_ bookmarks. Also was not able to restore bookmarks from a backup .json file. So I created a new profile, and was able to restore the bookmarks from the original profile's backup. That led me to exploring your suggestion. Thanks again!

When I downloaded the new Firefox about a week or two ago all my bookmarks, and add-ons disappeared and I want you to give them back to me asap?

You shouldn't wait that long to ask advice. Firefox only keeps a (rotating) backup of bookmarks for the last 5 days that you started Firefox. So you may be out of luck.
You can check that you still use your old default profile that had your bookmarks.

If you see disabled extensions that are not compatible on the next start in "Tools > Add-ons > Extensions" then click the "Find Updates" button to do a compatibility check.

Installed 4.0 - Firefox Start Page won't go away - why aren't homepage and add-ons saving?

After installing Firefox 4.0 the Start Page and Welcome to Firefox page returns each time I start Firefox. My homepage and add-ons won't save.

Thank you very much. I reset Firefox and it worked. I knew of MalwareBytes but had no intention of installing it before. I decided to install it anyway now and it even found 3 trojans that my Avira couldn't.
My first instinct was to reset Firefox to it's default state but I was afraid of losing my bookmarks, cookies, site preferences etc. so I didn't even bother. Now that I saw it was my last hope, I saw there is actually a phase between clicking the "Reset Firefox" button and the action being executed. The phase explains what the button will do and asks if you agree. I did not know that and I am really happy I could keep my old stuff.
Thanks a bunch, even if my instincts were right, I wouldn't have bothered to reset Firefox just because I'd be too lazy to get every setting back to how it was.
Thanks again!

Have TorBrowserBundle running Firefox ESR10.0.12 on Mac OS X10.8.2 after browser update how to migrate settings , preferences and add-ons?

Updated TorBrowserBundle and none of my settings, bookmarks,preferences,and add-ons were migrated to the new version. Have you had trouble with this before? I did not replace my older version, so can I migrate these settings and add-ons like is possible with the bookmarks HTML file export?

We are currently running 10.8.5 with Workgroup manager 10.8 and Server App 2.2.5
My question is, would there be any modifications i would need to make to your instructions for them to work on the above os and app version?

All of my extensions, and add-ons were deleted overnight. I can't find an old firefox data folder to restore my old profile

Firefox deleted all of my extensions and add-ons overnight. None of the fixes I've found work, I need help restoring my old profile

''cor-el [[#answer-716602|said]]''
<blockquote>
Did you only lose the extension or did you lose other personal data and settings as well?
You would normally only lose the extensions if you create a new profile folder, either via a reset/refresh or possibly because of problems with the profiles.ini file.
With a reset you would have an "Old Firefox Data" folder on the desktop.
</blockquote>
I only lost the extensions. I left the PC on to do a steam download overnight. When I woke up and opened up the browser it was in base mode. All of my tabs, saved data were present. I looked for the Old Firefox Data folder then, but it isn't there.

None if these crash reports seem to have been send.
Do you have crash reports with a "bp-" prefix that were submitted and that show a crashing thread?
Start Firefox in [[Safe Mode|Safe Mode]] to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

I just upgraded my Norton Internet Security and I've lost ALL my bookmarks and add-ons. The add-ons aren't a big deal, but can I get my bookmarks back?

After rebooting my PC to finish Norton's installation, I opened Firefox and all of my bookmarks and add-ons were gone. My persona was also missing, too. Is there any way to remedy this without having to go through and re-bookmark every page?
I also found an article entitled, "Bookmarks and toolbar buttons not working after upgrading," to which I was redirected after clicking on the link "Configuring Norton 360" from the article "Lost Bookmarks." However, it says that "This article is no longer maintained, so its content might be out of date."

Thanks, but I checked iCloud and it has none of them.
If it backed up to my laptop, that died and I just got the new computer. The one that's crashed won't even boot, so there's no way to even tell if it was syncing the contacts along with all the phone photos. Literally happened at the same time - it was because I had the new computer that I was finally able to pull the photos off the phone and make room for the upgrade. It had refused to upgrade for lack of space for some time.
I had thought it was set to sync to iCloud but it vanished from BOTH my phone and the cloud. That's why I'm so angry about it.

Will not allow add-ons,says that they are corrupted

You can try to clean install a fresh copy after uninstalling the present version via Windows Control Panel '''Programs and Features'''. While uninstalling make sure to choose deleting the preferences and folders. Please also see [https://support.mozilla.org/en-US/questions/916668#answer-305338 this] regarding problems with security software.
To backup important info which can be restored later, please see [https://support.mozilla.org/en-US/kb/Backing%20up%20your%20information?s=backup&r=1&e=sph&as=s this]. Some of the important files could be '''places.sqlite''' which holds the bookmarks and history, '''key3.db''' + '''signons.sqlite''' which are needed to restore the saved passwords etc.

Moving Calendar to a New Computer & Moving Data: Downloads and Add-ons

Moving Calendar to a New Computer & Moving Data: Downloads and Add-ons
The handle says is all. Totally lost here & in a virtual house of cards. Please first see screen-shot.
I have the Mozilla calendar (Lightening?) program on my computer. Is this screen-shot Thunderbird or is it an add-on called Lightening that was added on to Thunderbird? I don't even recall how I acquired in a few years ago. Whatever it is I find in invaluable. Indispensable. Brilliantly conceived. A superb creation.
Notice that I have several calendars in different colors for different purposes and a long task agenda on the right. Wonderful program!! I absolutely love it! I can not afford to loose these calenders and this data. However, big caveat, entrusting my life (our lives) to it has become extremely dangerous for it's a virtual house of cards upon the purchase of a new computer. The move-over is more like a career most of us already have one. Need anyone really wonder why PC sales are down? Res ipsa loquitur.
FIRST ISSUE:
I must move this/these Mozilla program/s and calendars over to the new computer but I don't have a clue where to begin. What must I download? Thunderbird? What must I add-on? Lightening? Is this a suite of programs? All I care about are my calendars and task agendas that you see in the screen-shot -- not any email programs etc. Just this personal management system that you see.
SECOND ISSUE:
After I downloading, installing, and adding-on what I need, how do I then move (migrate) my profile (data) over to new computer?
Please know that I do know where that 'profile' and its .ics calendar profiles are stored. I am also well backed up. I just need to know how get (downloaded/install) what I need and move this over to the new computer. (See screen-shot)
First, what must I download and install and add on. Second how do I move this data/profile (a virtual Life) over to the new computer without it all coming down like a house of cards?
Please, unless it's all been documented in one location, a link to this and a link to that probably won't be very helpful. Anyone who can lay-out a simple, easy to follow plan (1, 2, 3, 4, done) will be a hero and make a significant contribution to people who dread buying a new computer for precisely these reasons. It will certainly encourage more people to use this absolutely wonderful personal management system. It's the best I've ever seen and I must keep it. But it's soooo risky.

Obviously the screen-shot is posted so show what I see now and want to see when I am done. Was the ''really ''not clear? Nothing could be more germane ("Germaine" is a person's name) than a visual that shows the multiple calendar dynamic and what I actually want to see nor better communicants the fact that all I want is that and not other programs in a suite – a question btw asked but not answered.
"I have no idea what the threshold issue is. Perhaps Zeno can assist you."
I now see Zeno's reply but I never got an email re: my questions and just noticed it. I will respond to him separately. But ''obviously ''the ''''threshold'''' issue is ISSUE ONE (1) exactly what, and only what, must I download and install.
Was that really not clear? That was not answered in your first reply. And since you here, later, state that Lightening does not need to be downloaded and installed how on earth could you presume the first threshold issue (question 1) was a joke?
Once again I wrote and you even quoted me “Please, unless it's ALL been documented in ONE LOCATION, a link to this and a link to that probably won't be very helpful. Anyone who can lay-out a simple, easy to follow plan (1, 2, 3, 4, done) ...”
As this exchange demonstrates, that statement has certainly proven to be correct.
You then wrote, “Read the question... the question is. How do I move my profile to a new computer? You are the one making much more of it than that. ... All covered in the link.”
What “the” (singular) of several links (plural) you provided are you talking abut? But no matter. No it was not "all" covered in the multiple links you sent which do not address the more important threshold question (1). The only issue you addressed was (2) data transfer which is secondary to the threshold issue which is ISSUE question one (1). Threshold issue/question presented: before we can go to question (2) we must address question (1).
As I stated “Please know that I do know where that 'profile' and its .ics calendar profiles are stored.”
You replied “No you do not. Local calendars are not stored in ICS files.”
First please notice you make no attempt to clarify where they are; but, once again, please read carefully. I did not say that the calendars are “stored in the ICS files” but that the .ics files ARE the calendars and I do know there they are stored.
Please see the screen-shot you claim is not germane? Each of those different colored calendars are (“not stored” in but are) .ics files that are stored in the Profile directory. In the directory c:\Users\myName\AppData\Roaming\Thunderbird is a directory or folder called \Profiles and in that directory is a file named 9w2ydrc4.default. That file IS the profile. In that profile is a folder called “calendar-data” and in that folder are the calender .ics files that are the different colored calenders you see in the very germane screen-shot. So I do know where the calendars are. So I gather that all I copy into the Profiles directory is the file (profile) called 9w2ydrc4.default.
Again, as I wrote before, I do not want a full suite with email. So what do I downloaded and install to get only what you see in the screen-shot. I don't think we ever installed a full suite before. I never saw and email program. So, again,'' asked but not answered. ''
Then you stated, I do not need to download and install Lightening (please notice, is a partial answer to my first, threshold, question you presumed was a joke) but only Thunderbird since “Lightning is already in your profile so will move with it When you actually move the profile.”
Well, since you like to use links, exactly what is your documented Mozilla authority for that hearsay? Since I posted the question I have spent much time at Mozilla. Literally everything I have seen indicates I must first download and Thunderbird. But again, I do not want to and never did, install a full suite of programs and, as far as I know, there is no Mozilla mail or other suite programs on this (my current old computer) and there never were. So, once again'', asked and not answered).''
Everything at Mozilla states I must first download & install Thunderbird'' and then ''add-on Lightening. Nothing I have seen at Mozilla suggests otherwise or states that when we want to get Mozilla calendars over to a new computer we must first and *only* download and install Thunderbird and then just copy the profile (9w2ydrc4.default) into the 'Profiles' directory. Nothing I have seen at Mozilla suggests I do not have to download and install Lightening. So please show me where Mozilla documents that. ''' Please notice that even Zeno states, “You download AND INSTALL LIGHTNING as an add-on.'''”
Since this contradicts you do tell me: what is your Mozilla authority for claim that I do not need to download and install Lightening because it's already in my profile? I see nothing in my profile that suggests Lightening is there.
Finally, I wrote to you “ ...it is axiomatic that Windows transfer wizard does NOT transfer programs but only data. You did not know this?” I only wrote that because it appeared your reference to Transfer Wizard was a response to the threshold question of (1) how to I get the program onto the new machine. But your response is''' very '''strange for you wrote “You are the first person I have encountered that thought it did more than transfer data.” Show me where I said that. I said the opposite. How on earth did you come to that interpretation as a response to my simple and very clear statement that " ...it is axiomatic that Windows transfer wizard does''' NOT transfer programs but only data.'''.”

My add-ons manager and add-ons bar doesn't work at all

It's not that my add-ons are incompatible with Firefox; they all work fine. It's that, no matter what I seem to do, I can't have a look at them or manage or control them in any way. All that happens when I click on "Add-ons" or "Add-on Bar" is a "New Tab"; it's a completely blank screen with nothing to click on.
I've really been trying to do all I can, but I have no clue what the problem is. It's not any of the add-ons I have; I used the "Restart with Add-ons Disabled" option and disabled Adblock. It's not outdated Java. Is it something from my computer or a pluggin I still need?
Your help would be much appreciated. Thanks.

RightToClick . . . I don't see this in my Add-ons bar, or when I right click a page
. . . the description for an Add-on is still unhighlightable . . . even if I right-click it with this Add-on . . . should I be able to highlight it? Or does it have some other way to make itself un-copyable, besides javascript?
