How to stop Firefox from checking for add-on compatibility every time it opens?

That can be a problem with the compatibility.ini file in the Firefox profile folder.
Try to rename (or delete) the compatibility.ini file in the Firefox profile folder to see if that helps.
You can use this button to go to the currently used Firefox profile folder:
*Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)
*http://kb.mozillazine.org/Profile_folder_-_Firefox
You can also check for problems with preferences.
Delete possible user.js and numbered prefs-##.js files and rename (or delete) the prefs.js file to reset all prefs to the default value including prefs set via user.js and prefs that are no longer supported in the current Firefox release.

Very time I click on Firefox, a check for add-on compatibility runs also after a short time the screen fills with Firefox Android add; this is annoying. How

The latest Mozilla update change the way my computer starts when I click on Mozilla on the desktop. The first think that happens is that a small window appears and tells me it is checking for add-ons compatibility. After what seems like a long period, the screen fills with some sort of Mozilla about Android and Mozilla. I then have to x this to get to my email page. This is annoying. How do I fix this?

[[Firefox says it's just updated every time it starts - how to fix]]
It sounds like this issue.

Firefox freezes up for 2 full minutes, every time I open it.

After I open Firefox, I have about two or three minutes to browse around before it freezes up. I get the "not responding" message. This lasts for a full two minutes, at least. There's always time to pop open IE or Chrome and get the information I need, but usually wait it out.
It is this, and the fact that I am asked to load new Java updates and restart Firefox EVERY TIME I open the browser that is leading me toward switching to Chrome. Firefox used to be the better alternative, now I get more reliability out of every other browser I use.

How can I stop Firefox from making itself the default browser every time it upgrades?

Every time there's a new version of firefox, it updates automatically, but it changes the windows file type settings so that firefox is now the default browser.
I have gone to tools > options > advanced and cleared the "Always check to see if firefox is the default browser" checkbox. It's not an issue on startup, only on upgrade.
This happens every time there's a new version of firefox.

Unfortunately the "web browser" I want to use is just a compiled script that examines the URL and then launches the proper browser to open it (because some pages are not standards compliant and work better in a certain browser). It does not appear in the default web browser list, but when I go to Tools > Folder Options > File Types, I can edit the firefox URL, URL http and URL https types and then it will work correctly until the next firefox upgrade.

How can I stop firefox from checking add-ons and displaying the What's new page each time I launch it

Since upgrading to the latest version, I have viewed read and interacted with everything on the What's new page. I have done this a number of times but the page is still opened each time I launch Firefox. In addition it shows my homepage in a second tab.
Prior to opening Firefox it checks for add-ons.

hello Michells, this will likely be caused by the user.js file in your profile folder.
go to the firefox ''menu ≡ > help ? > troubleshooting information'', click on ''profile folder/show folder'' and close all firefox windows afterwards. a windows explorer window should open up - in there delete the file named '''user.js''' and restart the browser afterwards.

Is there a way to stop Firefox from suggesting to add new search engines to my search bar?

Is there a way to stop Firefox from suggesting to add new search engines to my search bar whenever I visit websites that suggest to us to add their search engines?
I searched a lot and couldn't find any help. How to stop websites from suggesting to my Firefox search bar to add their search engines? I don't want to add other search engines other than the ones I organized. I don't want my list to look more distracting and longer.

Firefox doesn't do that. That's either a feature of the website you are visiting or possible Malware on that PC.
A screenshot of that might be helpful. <br />
https://support.mozilla.org/en-US/kb/how-do-i-create-screenshot-my-problem <br />
It is best to use a compressed image type like PNG or JPG to save the screenshot and make sure that you do not exceed a maximum file size of 1 MB.

How do I stop Firefox from crashing? It crashes at various times, not when loading any specific pages.

My crash problem has been going on for week, now. I tried uninstalling FF and reinstalling it. I hoped that would fix the problem, but it didn't. Crashes occur randomly, when loading or reloading pages but they are NOT specific pages. The Report ID listed below is just 1 of several reports from the past week.

I am unwilling to attempt navigation away from these sites. The pop-ups that occur on the attempt to leave a site or to close the browser are exit traps offering incentive to stay.
Once upon a time, when the internet was less dangerous, I would be willing to close the exit pop-ups. Now, after twice being infected with malware trying to close the pop-ups, I now force close whichever browser I am using.
Recently, I clicked on the red X to close one pop-up, and it installed a trojan that I had to pay to be removed. When I clicked on 'Leave' in another exit pop, it didn't exit and it turned out I was giving permission to run a script file. Now that criminals have learned these exit pop-ups can be used to force a click action, the sites using them have become dangerous.
If I force the browser to close using Task manager, Please tell me how to stop FireFox from sending me directly back to the same site because it mistakenly believes it crashed when it did not. I forced it to close because I was on a site that had taken control of my browser and was not allowing me to leave the site.
No other browser sends me back to the potentially dangerous sites. I prefer Firefox, but the new version must have a setting that allows me to get safely away from a problem site?

Is it possible to keep an email account on the iPhone but stop if from checking for new mail?

I have an email account that has been deleted from the provider (Gmail), but I want to keep the old mails on my phone, while stopping it from checking for new mail. Is this possible?
If I disable the account to stop if from checking for new mail (and producing a bunch of annoying pop-ups every time the mail app is opened), the account becomes invisible and the old mails disappear. I want to keep them visible to I can read and refer to them, but want to stop the phone from trying to download new ones or check the account.
Any help appreciated.

Thanks for the thought. In this case, that doesn't really help much, as it requires a bunch of button pushing just to check emails. Plus, if I'm not mistaken, in addition to switching modes every time I check email, it also prevents the other accounts from downloading the most recent mails as well. Since it's possible to keep an account on a Mac computer, but take it offline, it's very disappointing if there isn't a way to do the equivalent on an iPhone so that it passively holds the mails but doesn't send constant pop-ups every time the app is accessed.

We are fellow users here on these user-to-user forums, you're not talking to iTunes Support nor Apple.
Have you tried closing all apps via the iPad's multitasking bar and then doing a soft-reset and seeing that helps ? To close all apps :
iOS 7: double-click the home button to open the taskbar, and then swipe or drag each app's screen from there up and off the top of the screen to close it, and click the home button to close the taskbar.
iOS 6 and below : from the home screen (i.e. not with any app 'open' on-screen) double-click the home button to bring up the taskbar, then press and hold any of the apps on the taskbar for a couple of seconds or so until they start shaking, then press the '-' in the top left of each app to close it, and touch any part of the screen above the taskbar so as to stop the shaking and close the taskbar.
Soft-reset : press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.

Those are the instructions for your computer's iTunes (i.e. using the Store menu at the top of your computer's iTunes and selecting 'View My Account' on it). If you are doing it on your iPad then are you following the instructions for iOS devices :
To unhide your purchases
Depending on the content type, open the App Store, iBooks, or iTunes Store on your device.
Scroll to the bottom of the main page.
If you're not already signed in, tap Sign In.
Tap your Apple ID name, then tap View Account.
Scroll down on the Account pane, and tap Hidden Purchases.
Locate the item you would like to unhide then tap the Unhide button.

I have recently update my Final Cut Pro X to Final Cut Pro X 10.1. I downloaded the update from the app store. Now every time I open Final Cut it crashes almost instantly. What can I do

I have recently update my Final Cut Pro X to Final Cut Pro X 10.1. I downloaded the update from the app store. Now every time I open Final Cut it crashes almost instantly. What can I do?- I really need help!

It sounds as though you have a corrupt project - or possibly a file within an event that is causing the application to crash.
Quit FCP X, then move your projects and events (if you have any) to new folders so that FCP X doesn't find them, then relaunch the application. If it launches OK, there's a very good chance one of your projects or events is causing the problem.
Quit the app again, then move one event or project at a time back to the original folder and launch FCP X again - keep going until you find the cause.

Acrobat X Not Reponding for 30 seconds almost every time I open a file

Acrobat X Not Reponding for 30 seconds almost every time I open a file
The title says it all.
This happens on 4 computer systems, including:
Windows 8 64-bit desktop, FRESH INSTALL
Windows 8 32-bit laptop, FRESH Install
Windows 7 64-bit desktop, REINSTALLED AND PROBLEM PERSISTS
Windows 7 32-bit laptop
I have read long forum postings of people having this problem on many different versions of Acrobat and Reader and tried many of the purpored solutions, none worked.
I would like some expert advice, but more importantly why hasn't Adobe investigated and solved this widely reported phenomenon that has gone on for years? There is no way I would upgrade to Acrobat XI (which some people report has this problem) unless Adobe acknowledges and fixes this.
Where do I report this issue to Adobe?

no idea what IPM is. not in the help file. any way, who cares? this is a bug that needs to be reported. where does one do that?

How to stop Firefox from launching everytime I turn on my MacBook?

Hi Everyone,
Everytime I turn on my MacBook, Firefox launches. It really bugs me, and I tried to stop it, but couldn't find how, either in system preferences or in the firefox menus.
Can someone please help and tell me how to stop it from happening?
Thanks already,
Quentin

This usually happens because you've added the application to the Login Items list in the Accounts preferences. Open Accounts preference, click on the Login Items tab, locate the Firefox entry, select it then click on the "-" button to delete it.
