Support Forum

The problem is basically exactly like described here, only the solution presented there does not actually work for me: http://askubuntu.com/questions/59062/a-script-on-this-page-may-be-busy-or-it-may-have-stopped-responding-everytime

What happens is that every time I hibernate my laptop (with Windows 7 Pro, 64bit), when I resume from hibernation, FF is completely unresponsive (hangs) for minutes. Easily around 5 minutes. Eventually a dialog box pops up with the following:

"A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete."

And the two buttons are: "stop script" or "continue". After I click "stop script" the unresponsiveness finally goes away, and FF starts working normally again.

I think possibly even clicking "continue" also makes it go back to normal, but I'm not sure anymore since I have recently just switched to sleep mode out of frustration in order to not deal with it anymore, and I don't remember exactly if I get the same result from clicking either option.

This is extremely frustrating.

Someone else reported an extremely similar symptom here: https://support.mozilla.org/en-US/questions/935110?esab=a&as=aaq It might even be the exact same symptom. Maybe that person simply never waited long enough for the dialog box to appear, but otherwise the unusability symptoms are the same.

I try to change the default search engine in the search bar (to Google) by following your instructions, including by deleting all the other available options, but every time I re-open Firefox, all the other search engines have re-appeared and the default engine is Yahoo, not Google.

As of late, my Firefox browser has been freezing my entire computer. It keeps saying that it is "not responding", my mouse turns into that blue circular loading screen, I can't exit anything, I can't even open task manager, I have to take the battery out just for my computer to turn off.

I scanned everything with Norton; didn't detect anything. I even did the Norton Power Eraser, still nothing. I set Firefox to run the program as an administrator and I thought it was fixed but it wasn't.

I even update my plug-ins and for some reason, your website keeps telling me I need to update the same ones, so I can't even rely on that.

I noticed that it does happen when I'm on a Youtube page. Like when I've paused a video.

It opens fast, it browses fast, it goes to certain websites fast. It's this annoyance that has really bothered me and has considered me switching to Google Chrome.

If you don't want me to, then tell me how to fix this issue.

Hi, after updating to Java 7 update 10 Java stopped working. Plug in checker indicates Java Deployment Toolkit 7.0.100.18 is installed correctly, but Java test page says plugin needed and Java Runtime Environment 1.7 u10 is available. Install fails. Uninstalled Java and tried manual install (including as administrator) but no resolution. All old Java versions have been uninstalled. Thank you for your time.

TODAY A "SEARCH HERE" TAB APPEARED ON MY HOME PAGE. I CANNOT FIND A "PROGRAM" TO UNINSTALL IT. I HAVE REBOOTED, RESTORED TO A PREVIOUS POINT AND IT IS STILL THERE. HOW DO I DELETE THIS TAB.

i reinstalled firefox to my desktop the previous one used to show my homepage google when i opened a new tab in my home page .but it doesnot open my homepage google now it is blank with some rectangular blocks

Didn't even do anything. Home page changed on its own. Tried a fix that was suggested on-line but that did help. Instead now have more "add-ons" and Yahoo has become the home page instead of my desired google although when bring up Mozilla always goes to the Start.Search.us.com first.

When Firefox is open - I will try to connect to Facebook.com. One of 2 things happen: Either the page will not open and the spinning circle will continue to spin until I close the page or Facebook will open but will not load pictures or any of the page correctly. I have deleted my cookies - which has not helped. I also cannot open Facebook in IE.

Any suggestions? Thanks!

Ok I have a new problem with the new Firefox. I just updated my Firefox to the newest version. But while I’ve been using the old version I use a very good feature I liked about Firefox a lot .that was the cache folder and cache files used to create for using software like downloading so many kind of files like videos pictures and any content I’ve browsed on the net by Firefox. All those files been there in a folder in this location (C:\Documents and Settings\A\Local Settings\Application Data\Mozilla\Firefox\Profiles\r52ck3aw.default\Cache) and I could use that to preview all those files but now when I go to that folder there is just like thousands folders and none of my file is there you only can find a few of them. Please don’t tell me that I no longer have that folder and cache files like the old versions? Please help?

I cannot log into my gmail or facebook account, because it says: cookies are disabled, enable cookies to continue. I tried changing my settings in Firefox - Options - Settings - Privacy - Use custom settings. I did exactly what I was advised in the Firefox Help online, enabled everything, then clicked OK. Didnt work. Tried it again and I only found that the settings (custom settings - enabled everything) were not even saved. I am not able to save these custom settings any way, it never saves them no matter how many times I try and click ok, I come back to the setting to find that they are not there. So I tried clearing all the cookies and cache in history (also found this online in firefox support site), guess what? DIDNT WORK. I am starting to be a little bit pissed off as I cannot log into my gmail or facebook account for over two weeks now! Any time I need to check e-mails I have to use someones laptop.

Often, when I'm browsing with firefox a pop-up page appears: always from speedanalysis.net. I have never used this service nor do I want this service. I have ad-blocker installed. How do I prevent this annoying pop-up in the future?

just installed FF 18.0 on Linux (Centos 5.8) where 17.0.1 has been running fine.

I always install in a local (to my login) directory, and have a desktop launcher to start it. I download each .tar.bz2 FF package to a subdir, where I unpack it, overwriting whatever was already in the firefox directory in that location.

doing that, I get the error above. so I renamed the directory and did a fresh extraction into the firefox directory that tar creates when unpacking the archive. SAME PROBLEM.

moving that directory aside and re-extracting the 17.0.1 archive yields a working Firefox.

What can I do to solve this problem?

the troubleshooting info below came from FF 17.0.1, since FF18.0 doesn't work.

I've gotten the font size of the tabs and menu bars and buttons too large, in both firefox and thunderbird, and can't figure how I did it or how to shrink them to the right size. This is not the websites I'm talkling about, but how the program displays are sized. I've gone over and over the menus and options and can't find the adjustments.
