Compatibility reporter says none of my add-ons will work wwith FF4, is this possible?

I think "compatibility reporter" can't be right. I have updated add-ons that claim to be compliant with FF4 but "c/r" says none of my add-ons will work.

Firefox 4.0 and 4.0.1 are not secure and are no longer supported - USE AT YOUR OWN RISK.
*There are already reported attacks on the internet against users of Firefox 4.0 and 4.0.1.
*Firefox 4.0 and 4.0.1 contain security issues that '''''have not''''' and '''''will not''''' be updated according to the latest information.
*Firefox 5.0 includes fixes for the security issues in Firefox 4.0.1
*Firefox 4.0.1 included fixes for security issues in Firefox 4.0.
Only Firefox 5.0 and 3.6.18 are currently supported.

In addition, your outdated plugins contain security issues, so you are even more at risk.

Here's the link. It's a long list and unfortunately, it's not in alphabetical order. So it'll take some time to go through them:

I need it and also want to install the new Firefox

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.

Firefox 19 add ons stopped working

Hello.
I installed Firefox 19. Immediately most of my add ons stopped working, and in some cases work but not correctly.
Here are some examples:
Noia4 - works, but each time I restart Firefox Noia4 reset to default settings.
Reminder Fox - Does not work
Status4Evar - Does not work - These may be related.
Google translator for Firefox, does not work.
AnonymoX does not work.
I have not had time to try ALL my add ons, so until I can be sure these work correctly I have returned to v18.

It is possible that there is a problem with the file(s) that store the extensions registry.
Delete the files extensions.* (e.g. extensions.sqlite, extensions.ini, extensions.cache) and compatibility.ini in the Firefox profile folder to reset the extensions registry.
*https://support.mozilla.org/kb/Profiles
New files will be created when required.
See "Corrupt extension files":
*http://kb.mozillazine.org/Unable_to_install_themes_or_extensions
*https://support.mozilla.org/kb/Unable+to+install+add-ons
If you see disabled, not compatible, extensions in "Tools > Add-ons > Extensions" then click the Tools button at the left side of the Search Bar (or click the "Find Updates" button in older Firefox versions) to check if there is a compatibility update available.
If this hasn't helped then also try to delete the addons.sqlite file.

I use Google chrome and for no reason all my add-ons will not load.

Yesterday AM when I logged onto my laptop and opened Google home page, none of my add-ons (gadgets) would load. This has gone on for 2 days now.
I have rebooted, checked to make sure the site was listed as safe for add-ons and checked settings. Nothing has worked so far. Also when I clicked on "change google themes" there was no response.
Any ideas?

If your problem is with Google Chrome you would be better off asking in the Google Chrome support forums - http://www.google.com/support/chrome/

Is there a way to see which of my add-ons will be disabled when I install Firefox update?

I have recently returned to Firefox after a long absence. The reason I stopped using it in the first place is that every time I got all the add-ons that I wanted, there would be a new update and I'd lose some or all of them and I wasn't interested in having some/all of my useful functions disabled until who knows when or forever.
I've currently got automatic updates turned off, and that is where they will stay unless I can verify that the add-ons are backwards compatible or there is an update for the add-on.
Is there a way to see what current add-ons will be disabled with an update?

Yes, during the update there is a list of add ons that come up that will not be added when you update. You can cancel the update if it lists one that you do not want to no longer use.
The block list is also here: [https://addons.mozilla.org/en-US/firefox/blocked/]

Add-ons not working properly

Recently (last 4-5 days my add-ons stopped working properly. Example: Tab Mix Plus shows as installed, but when any options I select do not affect tab behavior; Lastpass icon not showing up in the Add-on bar as it did previously; Newsfox icon doesn't appear in Toolbar as it did. Using Firefox 26.0 on Windows 8 on Dell Laptop.

I've been having problems with my add-ons. Ad Block Plus will often hang Firefox and drive the CPU to 100%. I've reset Firefox and installed ABP, but still have the problem. My other extension have also stopped working. Any new extensions will appear to added on to Firefox, but they also don't work. I've followed all on-line trouble shooting options.

I have 3.6.28 what add ons will i lose if i upgrade to 18

I have 3.6.28 what add ons will i lose if i upgrade to 18

please note that continuing using an outdated versions of firefox like 3.6.28 which is [https://www.mozilla.org/security/known-vulnerabilities/firefox.html affected by numerous known security vulnerabilities] will put the integrity of your system and all the personal data on it at risk! so I'd recommend updating as soon as possible.
in order to answer your specific question it would be necessary to know which addons you've installed specifically - google toolbar won't work any longer but there are quite a few alternatives: [[Google Toolbar is no longer compatible with Firefox - Here are some alternatives]]

"Upgrades" make many "NEEDED" Add-ons STOP Working! (ie Kaspersky Pwd Mgr, FEBE, No-Script, Skype, and MANY More wont work!) Why is this? I fear the ppl who write the Add-Ons will become frustrated and will stop. Plz email me- Thx

Im not sure what other details I can give you, that would be pertinent. email me and ask me what you will .. and Ill be happy to oblige you. But having suggested Firefox to many of my clients (I owned a Computer Sales and Service (STORE - not a basement operation) for over 15 yrs and even on our New Computers, FIREFOX is what we installed and recommended! Many of my old clients now (Had to close the business last year due to a number of factors) call me at home and are asking me the same question. Why wont my ADD-ONS work with Firefox. Firefox tells me to Upgrade to the new one, and suddenly we cant get .... (their add ons) to work.
I know Kaspersky was another product we sold a lot of, so their password managers are no longer working properly. More specifically their AUTO FILL function will not load when a new web page is loaded, thus the person can not access their bank acct, etc ... as they were dependent on Kaspersky to do all the remembering for them!

I updated Firefox and the extensions and keep getting "restart firefox for changes to take effect." Even after restarting, none of the add-ons actually update and do not appear, for instance, noscript. Please help!

There are a bunch of add-ons that recently were updated, including noscript, adblock, etc. These add-ons were updated successfully and say in the add-on window they will be installed the next time Firefox restarts. There's also a bar that says "restart firefox now" and even when clicking restart firefox, none of the updates seem to load. I had to manually download the noscript the last time to get it to work but alas with the latest update, again, same problems. i tried disabling other plugins with no impact either. Anyone else having a similar problem and does anyone know how to get this resolved?

Delete the files extensions.* (extensions.rdf, extensions.cache, extensions.ini, extensions.sqlite) and compatibility.ini in the Firefox [[Profiles|profile folder]] to reset the extensions registry. New files will be created when required.
See "Corrupt extension files": http://kb.mozillazine.org/Unable_to_install_themes_or_extensions
If you see disabled, not compatible, extensions in "Tools > Add-ons > Extensions" then click the "Find Updates" button (in Firefox 4: right-click the extension -> "Find Updates") to do a compatibility check.

Why will None of the Add ons Load in 3.6?

Why will none of my add on's load? I have used "Down Load Helper and a Screen Capture" fo years. Now Fire Fox will not load them.
== This happened ==
Every time Firefox opened
== I Switched to Windows 7

Tried to do the compatibility check with "Find updates". The command doesn't "light up" The only two that can be used are "options" and "Cancel Install." Have also reinstalled the add-ons with no luck.

Why did I download FireFox 11, when none of the add-ons work on it?

I was using Google Chrome to use on Facebook. I had problems with it and multiple users told me the way to go was to switch to Firefox. I downloaded it and while reviewing the get aquainted information, it seems most of the add-ons say" Not available with Firefox11. Why did I bother if their newest product does not support their own add-ons?

Why start out as a new Firefox user with a '''''Beta''''' version that is still two weeks away from being released?

How come absolutely none of my add ons/extensions are working even when i try to redownload them?

it has been approximately four months since my add ons/extensions haven't been working and i just cannot figure out why. one day i opened firefox and each one of my add ons started to not work anymore [there was no update i might ad so lack of compatibility is out of the question also since most of my add ons are compatible with at least version 3.6] i'm running on windows vista 64bit premium home edition. yeah. please help me because this is really annoying and i cannot download any youtube videos nor music from any other website. thanks in advance
