How to stop FF checking compatibility of add-ons every time it starts.

Since upgrading to 4.0.1, FF checks compatibility of add-ons every time it starts. How to stop this?

Did you delete prefs.js in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Firefox Profile Folder]?
* Help > Troubleshooting Information > Profile Directory: Open Containing Folder
This can also be a problem with the file(s) that store the extensions registry.
Delete the files extensions.* (extensions.sqlite, extensions.rdf, extensions.cache, extensions.ini) 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 (Firefox 4: click the Tools button at the left side of the Search Bar) to do a compatibility check.

Firefox checking compatibility of add-ons every time it starts.

Every time I upgrade, Firefox begins checking compatibility of add-ons every time it starts. And it brings up the "Hooray! Your Firefox is up to date" page every time too. How to fix?

Removal of "Compatibility of add-one" every time I start 7.0.1. Not wanted.

I don't like to have a test run every time I start Firefox 7.0.1. This did not happen with previous versions. It takes unnecessary time
to start. How do I turn this test off.
Windows XP Pro with all updates. Google as my home page.

upgrade your browser to Firefox 8 and check

Why does Firefox check compatiblity of add-ons every time I open it? Why am I then directed to Mozilla home page? Why did you not answer this question the last time I asked it?

This is annoying. Iwant to start using a less troublesome browser but I like Firefox otherwise.

Firefox checks for updates to add-ons every time it starts?

Every time I click my shortcut to open Firefox, a window pops up. This window scans my installed add-ons and checks for updates. Then, Firefox opens. One of my add-ons, "Zotero Word Integration" tries to install itself every time. If I have an instance of Microsoft Word open, this installation fails, but ultimately, Firefox opens and runs fine. The add-on scan takes approx. 30 seconds, so if I accidentally close FF, it's a big hassle. This first started happening after I updated to FF 8. I downloaded and installed FF7 but the problem persisted. Now, I am back to FF8, but, alas, nothing has changed. None of my other add-ons are having problems except for the ones that aren't compatible with FF8 yet. FYI, I do have Roboform, but it is the current version, both to-go, and everywhere.

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 do a compatibility check or see if there is an update.
Create a new profile as a test to check if your current profile is causing the problems.
See Basic Troubleshooting: Make a new profile:
* https://support.mozilla.com/kb/Basic+Troubleshooting#w_8-make-a-new-profile
There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.
If that new profile works then you can transfer some files from the old profile to that new profile (be careful not to copy corrupted files)

Is anyone else having issues with firefox checking toolbars and add ons every time you log on after upgrading to 10.0.2

I upgraded to the newest Firefox 10.0.2 a few days ago and now every time I log onto the internet with Firefox it says checking tool-bars and addons and loads slowly with my homepage and Firefox page saying thanks for upgrading anyone else having this issue have 2 tool bars that load they are charter and yahoo

Which security software (firewall, anti-virus) do you have?
Some security software has virtualization features that can cause problems by protecting and restoring files in the Firefox profile folder.

Why does CC keep reinstaling Add-ons every time I start my system? e.g. Server Behavior

Reinstalls every time. As well as this irritation why is there no filter in the Add-ons site to differentiate between what's compatible with CC2014 and other add-ons built for earlier iterations of Creative Cloud. Surely there should be?

How do I completely disable initial "Checking Compatibility of Add-ons" pop-up for all users on a Citrix server where the FireFox was upgraded to 29.0.1

I have a set of Citrix servers, we need to upgrade the FireFox on them to 29.0.1
When I have done this, and a user runs FireFox, now the users are being presented with a pop-up "Checking Compatibility of Add-ons" which delays the start of FireFox.
I need to prevent this so users just see FireFox start up without any delays.
I have installed the add-on that re-enables extensions.checkCompatibility and tried various ways of implementing it like pref("extensions.checkCompatibility", false);
However we seem to have a situation where the add-on that enables the setting is not loaded yet so the setting is not implemented.
How do I solve this for all users?

You can try to set the browser.startup.homepage_override.mstone pref to ignore on the about:config
*http://kb.mozillazine.org/browser.startup.homepage_override.mstone
You can use a mozilla.cfg file in the Firefox program folder to specify new (default) values and possibly lock prefs.
Place a local-settings.js file in the defaults\pref folder where also the channel-prefs.js file is located to specify using mozilla.cfg.
pref("general.config.filename", "mozilla.cfg");
These functions can be used in the mozilla.cfg file:
defaultPref(); // set new default value
pref(); // set pref, but allow changes in current session
lockPref(); // lock pref, disallow changes

After updating firefox the first window after opening first time "checking compatibility of add-ons" window is froze won't progress pas 1/3 of completion

I updated my fire fox on my MAC OS X to 3.6.6 version of firefox, everything went smooth till I open FireFox then the window firefox update opens up and about 1/3 through the process it gets stuck on Checking Compatibility of Add-ons and doesn't go any further. I have hit cancel and firefox opens but it doesn't open any web sites. I have removed firefox and re-installed and it is still doing the same thing. I have also let it run over night thinking it may just take a while and it never progresses, please advise, I am new to MAC but FireFox is the only browser on my mac that will open one of my business pages, known issue with mac for this company.

"Checking Compatability of Add-ons" Update window at each startup & redirects to a welcome page. Tried disabling all add-ons & updates / force compatability checker. Thoughts?

Each time I start Firefox a "Checking Compatibility of Add-ons" update window appears, which redirects me to a welcome to Firefox 5.0 page with my normal home page in another tab. I tried disabling all add-ons and updates as well as the force compatibility checker. I think my AVG safe-search bar might be causing the problem, but I have it disabled and never use it. Please help me get rid of this.

I am not clear what your problem is and importantly whether you are trying to ask for help with Firefox.
If you have a Firefox problem can you explain what you need help with please. If the problem is with a new Windows 8 operating system you will need to find a suitable forum to discuss that.
A websearch will turn up many suitable fora one possibility is

The people who answer questions here, for the most part, are other Firefox users volunteering their time (like me), not Mozilla employees or Firefox developers.
If you want to leave feedback for Firefox developers, you can go to the Firefox ''Help'' menu and select ''Submit Feedback...'' or use [https://input.mozilla.org/feedback this link]. (You'll need to be on the latest version of Firefox to submit feedback). Your feedback gets collected at http://input.mozilla.org/, where a team of people read it and gather data about the most common issues.

Checking compatibility of add-ons always running after update

After updating Firefox to version 6, the checking compatibility of add-ons is always running with each start of Firefox, and "Welcome to Firefox" site is always opening as well.
This is very disturbing.

Apparently I wasn't clear or the word upgrade wasn't right. I meant going from 4 to 5. I downloaded it, installed it and got no option resembling that at all, it just saved a DMG to my hard drive and then told me to put it in my applications folder as always. I opened it and that was that, no compatibility check. I already got one error about an add-on that's vital. I'd backed up before I installed and saved Firefox 4 as a separate file before opening 5, I hope I'll be able to go back to it. The old system was really much better, what's the point of finding out after you already installed something if your systems will work? Or of avoiding installing because you're afraid they might not when everything very well might be fine? I can guarantee you that I won't be installing an major updates for a very long time, that's for damn sure.

How to stop multiple auto-switching to address bar every time I open a new tab and try to type something anywhere outside of address bar?

How to stop multiple auto-switching to address bar every time I open a new tab and try to type something anywhere outside of address bar? Like something just wants me to use that embedded search when u type something not-web-address in address bar and hit enter. And the most ridiculous thing is that it happens repeatedly on like every second, like I just move down from address bar and start typing again, but then again it switches me to address bar, and 3, 4 times like that. And the result is also that I can't see the address of that page.
I think its has something to do with my AVG antivirus, because this started the same time some AVG Nation started to appear in every new tab i open (and thats also irritating me, I read about it here on support.mozilla.org and it seems that the only solution is to completely reinstall Firefox, but I dont want to lose all my settings) but when i type something in address bar and hit enter it opens the search results in Google.
Please try to help me, I like Firefox but I must switch to Chrome until I fix this problem.
Thanks in advance

First, please update to Firefox 32. 22 is no longer support nor is it secure. Then let us know if you still have this problem. [[Update Firefox to the latest version]]

How to stop an error message that pops up every time I open Safari. It reads...Safari 5.1 (v6534.50) has not been tested with the plugin PithHelmet .As a precaution, it has not been loaded. Please contact the plugin developer.

How do I stop this error message from popping up every time I start up Safari ?
Error message reads...
Safari 5.1 (v6534.50) has not been tested with the plugin Pithhelmet 3.0b6 (v 3006)
As a precaution, it has not been loaded. Please contact the plugin developer.
I have removed every trace of Pithhelmet, (via spotlight)
Trashed the preferences for Safari, restarted computer to no avail.
It just keeps keepin on.
Thanks

In the past I was able to bypass the message by editing the Info.plist file and updating the MaxBundleVersion variable, but not so this time around. As of today the developer seems to indicate there's no immediate fix becuase of how Safari 5.1 handles multiprocess page rendering. Probably best to stay tuned to Mike's website for now.

Checking compatibility of add-ons BEFORE upgrading

There used to be a feature that would pop up with announcements that major Firefox upgrades were available where you could run a compatibility check with your add-ons before you upgraded. This current system where you upgrade and then hope that your favorite add-ons work and just report them if they don't is frankly useless. My add-ons are more important to me than any new features 5.0 is offering. I'm not as worried about security as I am about convenience. Add-ons are the reason I use Firefox and if they don't work then I don't need it. So is there a way to check compatibility before I upgrade? I've looked and can't find it and I've searched help and can't find an answer. Thanks in advance for your help.

Apparently I wasn't clear or the word upgrade wasn't right. I meant going from 4 to 5. I downloaded it, installed it and got no option resembling that at all, it just saved a DMG to my hard drive and then told me to put it in my applications folder as always.
