Plugin check opens every time I start firefox

I did a search and none of the solutions seem to help.
- I checked plugins.update.notifyUser and it was set to true. I changed it to false and it worked one time. Then the next time it's back to true
- I ran the error console code to update blocklist.xml
- I disabled all my plugins and extensions
none have helped yet.

yep, that seems to have done it. I was holding off on the latest version because one of my plugins wasn't compatible, but I guess I can live without it. It's less annoying than having the plugin check run every time.
Below is the plugin info, if you still want to see it.
Thanks!

How do I stop one extra tab from opening every time I start Firefox?

Every time I open Firefox, my Yahoo homepage opens, but an additional page also opens which has a variety of website thumbnails and nothing else on that page.
In my Options, I have ONLY www.yahoo.com selected as my homepage, so only ONE page should be opening every time I start Firefox.
However, no matter what I do, this second page continues to open every time. It's very irritating, as half the time I've already begun to enter data into my homepage, then the second page pops up and switches to that and I'm typing on that page.
Please advise.

@jscher2000
Thank you!! That fixed the problem. The only add-ons I have are for my anti-virus software WebRoot, but somehow I must have installed Speed Dial without realizing it.
That fixed the problem. Greatly appreciated!!

FIREFOIX CHECKS EXTENSIONS EVERY TIME I START FIREFOX. HOW CAN I STOP THIS.

I DON'T WANT TO RESET FIREFOX. I DID THIS ONCE ALREADY AND HAVE NOT BEEN ABLE TO GET FIREFOX RUNNING AS IT WAS BEFORE I DID IT. IT NOW STARTS VERY SLOWLY AND CHECKS EXTENSIONS. CAN I REVERT TO VERSION 25. OPERATING SYSTEM WIN 7 HOME PREMIUM 64 BIT

It is possible that there is a problem with the file(s) that store the extensions registry.
Delete the extensions.* files (e.g. extensions.json, extensions.sqlite, extensions.ini) 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 or not compatible extensions in "Firefox/Tools > Add-ons > Extensions" then click the Tools button at the left end of the Search Bar to check if there is a compatibility update available.
If this hasn't helped then also delete the addons.json and addons.sqlite file.
You can check for problems with preferences and delete a possible user.js file and numbered prefs-##.js files and rename (or delete) the prefs.js file to reset all prefs to the default value.

Every time I start Firefox, why do I get a Google sign-in tab?

I’m using Firefox for Mac vets. 34.0.5, and I get that extra tab that opens every time I start Firefox in addition to the Home page I specified in Preferences. How do I stop that from happening?

Type '''about:config'''<Enter> in the address bar.
If a warning screen comes up, press the '''Be Careful''' button.
This is where Firefox finds information it needs to run.
At the top of the screen is a search bar. Type '''browser.newtab.url'''
This tells Firefox what to show when a new tab is opened.
If you want, right click and select '''Modify'''. You can change the setting to;
'''about:home''' (Firefox default home page),
'''about:newtab''' (shows the sites most visited),
'''about:blank''' (a blank page),
or you can enter any '''web page''' or '''about: page''' you want.
The same instructions are used for the new window setting, listed as
'''browser.startup.homepage'''.

How do I fix: The Plugin Check comes up EVERY time I start Firefox, AND I've installed Adobe Acrobat over 3 times but it still shows up as outdated

I crammed the info into the subject line, but to repeat...
Every time I start Firefox, the Plugin Check runs. Every ... single ... time. Very annoying. How do I get this to stop?
AND
I installed Adobe Acrobat at least 3 times, but it still shows up as "outdated". Obviously, it only truly installed once, but I tried clicking the button in vain hope that that will fix it.
But really, I simply don't want the Plugin Check to start every time.
thx

Alas, I already tried setting it to False (read it online somewhere) and it doesn't work. Perhaps if you could give guidance on why the Adobe install isn't completing, that would solve the plug-in check issue... Fingers crossed.

I desperately would like to update Firefox to version 10 from version 9 but each time I try, I am stuck with FF10 checking addons for comparability and the Welcome page opening every time I start the browser.

Windows 7 64 bit
I desperately would like to update Firefox to version 10 from version 9 but each time I try, I am stuck with FF10 checking addons for compatability and the Welcome page opening every time I start the browser. I continue to have to revert to version 9 to resolve this issue.

Sorry to be a while getting back! Tried all of that with no sucess so this AM, bit the bullet and deleted the FF folder from programs and downloaded and installed FF 10.01. Still was plagued with the same problem. Went into the appdata folder and there were two sessionstore.js files. Deleted them both, restarted the browser and no compatibility check for add-ons was done at start up and the extra tab for Welcome to FF was no longer opening Everything seems to be working as it should and I did not loose any of my settings.. Thank you for trying to help and I hope my solution helps anyone else who might experience this in the future. Here's hoping the next update goes smoother!

Plugincheck opens in a tab every time I start Firefox.

Lately, every time I start Firefox, I get two tabs: one with my homepage (which I expect), and the other tab is https://www.mozilla.com/en-US/plugincheck/. The plugincheck tab is in the foreground and quite annoying. Why did this start happening? How can I stop it?

What is the value of the pref plugins.update.notifyUser on the about:config page?
To open the about:config page, type about:config in the location (address) bar and press the "Enter" key, just like you type the url of a website to open a website. 
If you see a warning then you can confirm that you want to access that page. 
You can use the Filter bar at to top of the about:config page to locate a pref more easily.

In addition to my home page, every time I start Firefox a tab opens with notifacation of an updated addon. Why does this tab continue to appear even though there is no updated version of the addon?

Windows asks "Do you want the following program to make changes to this computer?" every time I start Firefox.

Neither my shortcuts nor my firefox.exe have Run As Administrator checked. And yet I get this prompt every time I start Firefox on my new laptop with Windows 7 Professional 64-bit.

unchecking "Run this program as an administrator" under the Compatibility tab in the properties of the program was my first guess....darn.
Ok I understand that this is only happening in Firefox. If you start it in safe mode does this still happen? This will tell you if its an add on or a changed configuration:[[Troubleshoot Firefox issues using Safe Mode]]

An extension automatically installs every time i start firefox

An extension from local system automatically installs every time I start Firefox after PC restart. I tried to disable it, remove it, but again after restart, it appears there. My question is how to disable addition of extensions and plugins from local system and how to block an extension. Extension name is Apps Hat 0.93.32 by nero

Thanks @the-edmeister , but your answer not satisfies my question. I also asked about disabling addon installation from local system and block an extension forever in firefox

How can I make my computer sync every time I start firefox?

I want to setup my computer sync automatically every time I start Firefox. Is there any way to do this?
Thanks for any reply..

That is the way Mac OS X 10.8 (aka Mountain Lion) works by default. Are you actually running that system? (See About This Mac in the Apple menu.) If so, make sure the check box in the shut down alert is checked:

Is it possible to NOT have 'Restore Previous Session' option come up automatically every time you start Firefox?

A large envelope pops up mid-screen every time I start Firefox, asking if I want to restore previous session. I don't want all users after me to have this option, but don't want to keep an empty history either. Can I deselect this option somewhere? Looked around, but found nothing.

Unfortunately changing the options found under "Completely disable session restore" does not make any difference to this problem.

Why is it that every time I start Firefox I have to fix the proxy settings in the connection area of options?

Every time I start Firefox I have to click on Tools, go to Options, then under the Connections tab select settings and change the proxy to "no proxy" from "Manual Configuration". Why is this doing this?
