Almost every time I open Firefox some bookmarks move up, and down the sidebar. Anyone know how I can fix this frustrating problem?

I have many bookmarks in folders. The folders, and some plain book marks move up or down from where I place them every time I open I open Firefox 4.0. I have even put them back to where I want them to be, and next time I open Firefox they move like they are playing Hide & Seek! Also from time to time there are new bookmarks added named "about:blank: I deleted the 8 ones created last week a few days ago, and now have 6 more! I am also having problems deleting some plugins, but that is another issue to worry about later.

Any chance you are using the Sync service?

I have a 2008 vintage iMac with 2.8GHz processor and recently upgraded to OS X 10.9.5. Soon after theupgrade the mail system started switching the senders address to another address, but same user name. How do you fix this?

Thanks for the reply,. I went to the site provided and executed the directions but this did not solve the issue.
Even more details:
If I send a message to the Jane Doe address from another account on this machine (all my family uses the same email services provider and each have accounts set up on this machine), when you open it, it shows Jane Doe then the <applejax.xx> address AND the picture associated with the Apple Jax account.
So the problem shows up when the message is sent to this account from this machine, AND when it is sent from this machine from this account. No other accounts on the machine are effected.
I have sent and received email messages from the mail service provider's website, and everything is fine.

I just downloaded the new version of Firefox (ver 4). Now when I open Firefox I get the address bar but the information part of my screen is blank. This happens on all web sites. How do I fix this? IE works fine.

Did you check your security software (firewall)?
A possible cause is security software (firewall) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process.

I can't sort iTunes U lectures properly. I can sort them properly on my laptop in iTunes, but when I transfer them to my iPhone, they are all jumbled up. How can I fix this?

I'm using my iPhone for listenting to lectures on iTunes U. When I download lectures to my laptop, they are sometimes arranged non-sequentially. I can fix this by renaming the files (e.g., with numbers in the titles), and then sorting by title. However, when I transfer the audio lectures to my iPhone, they are all sorted by "release date" (and frequently the release date is the same for each lecture), and this screws up the ordering. This means that when I'm listening to the lectures, they are all out of order.
I can find no setting on the iPhone for changing the ordering of lectures in iTunes U, nor can I find a way of changing such things when the iPhone is plugged into my laptop. For example, when I connect the iPhone to the laptop, and open iTunes, I select the device (i.e., the iPhone), look at the lectures in iTunes U, and iTunes will not let me change the column that sorts the files.
Any suggestions about how to correct this problem?

You can sort your library by adding a Sorting info in the File Info. Select a file in iTunes U, press cmd + i, choose Sorting Tab. For example add a Sort Name. For each file you have to put a value into that field, I did it with 01, 02, 03 .. 12. I do not know if this works if you select multiple files, but I did not try.
The next time you sync your device, your files will be in order. It' ve tested it on an iPad2.
If you ask me, there must be a better solution for that problem as the files have a track number saved in the info as well, and it is quite annoying to add the sorting order manually.

When I try to open FireFox it says I am missing nspr4.dll and mozqlite3.dll. How do I fix this?

I downloaded FireFox 8.0 not too long ago, and when I launched it, it said nspr4.dll and mozqlite3.dll were not found on my computer. I've used FireFox for a long time, and this has never happened before.

Do a clean (re)install and delete the Firefox program folder (C:\Program Files\Mozilla Firefox\).
Download a fresh Firefox copy and save the file to the desktop.
* Firefox 8.0.x: http://www.mozilla.com/en-US/firefox/all.html
Uninstall your current Firefox version if possible.
*Do not remove personal data when you uninstall the current version or you lose your bookmarks and other data in the profile folder.
Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
*It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
Your bookmarks and other profile data are stored elsewhere in the Firefox Profile Folder and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.

Picasa slide shows stopped working in Firefox. They work fine in Google chrome. How do I fix this problem?

I update a website for a Habitat for Humanity website. I have used the Picasa slideshows for years and they have worked perfectly in Firefox until Friday.
They still work perfectly in Google Chrome. So, the problem is specific to Firefox. I have updated the Flash Player. What do I need to do to fix the problem? It is important for our affiliate to have people be able to see the photos of volunteers at work building.

I usually scroll with page up/page down on my laptop. With firefox, it will go back and forth between my previous pages. How do I fix this?

My question pretty much sums it up. I like to scroll with the page up/page down buttons, and it's hit or miss working with firefox lately. It will go between my previous pages that I've visited instead of scrolling down the page.
Any suggestions?

When you say ''"It will go between my previous pages that I've visited"'' like clicking Back button to go to a previously browsed webpage ?? OR does your current Tab switches back/forth to previous/next tabs located in the Tab Strip(Tab bar) ??

Firefox hangs even after doing a complete factory restore on computer. How do I fix this? Its taking 5 mins to respond.

My computer is a Dell with Windows Vista. I just did a complete factory restore, not the system restore. Firefox was the first thing I downloaded and it still doesn't respond quickly and sometimes has to be shut down with the task manager. It's the lastest version of Firefox, unless you folks put something older out there on the home page. I love Firefox and would like it back in working order. Please help.

My "extentions.ini" disappears when I close Firefox forcing me to re-authorize the installation of all my extensions. How can I fix this?

I was also missing the "extensions.sqlite" file but changing the folder properties from read only allowed that file to save.
AV installed is Bit Defender but I do not see a section there that would be protecting that folder from overwrites.

That is the extension registry file file used in Firefox 3.6.x versions and is no longer used in Firefox 4+ versions (replaced by extensions.sqlite) and can be removed. There may be other leftover files if you've used this profile folder with older Firefox versions.

CTRL+H and CTRL+B have stopped working for Firefox. Every other CTRL command works. What's wrong and how do I fix it?

Whenever I want to open my history (CTRL+H) or my bookmarks (CTRL+B), I use those commands. They've always worked. Yesterday, they mysteriously stopped working. Every other CTRL+KEY command still works flawlessly.
I haven't done anything out of the ordinary in the past few days, and I've already tried to restart my computer. What could be the cause of this?
Thanks.

'''Try the Firefox SafeMode''' to see how it works there. 
''A troubleshooting mode, which disables most Add-ons.'' 
[https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode#w_safe-mode-window_2 Troubleshoot Firefox issues using Firefox SafeMode]
When in Safe Mode... 
* The status of plug-ins is not affected.
* Custom preferences are not affected.
* All extensions are disabled.
* The default theme is used, without a persona.
* userChrome.css and userContent.css are ignored.
* The default toolbar layout is used.
* The JIT Javascript compiler is disabled.
* Hardware acceleration is disabled.
* You can open the Firefox 15.0+ SafeMode by holding the '''Shft''' key when you use the Firefox desktop or Start menu shortcut.
* Or use the Help menu item, click on '''Restart with Add-ons Disabled...''' while Firefox is running.
''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before using the Firefox shortcut (without the Shft key) to open it again.''
'''''If it is good in the Firefox SafeMode''''', your problem is probably caused by an extension, and you need to figure out which one.

I'm living in Japan and can't get the firefox to set to English. I don't speak Japanese. How do I fix this?

I am attempting to install the Firefox program on my computer. However, since I live in Japan, somehow all the writing on the Google portion comes up in Japanese. How do I change the language to English?

Looks like you are using the en-US version of Firefox however it is probably going by your IP location.
http://www.google.com/support/websearch/bin/answer.py?hl=en&answer=873
If you'd rather use a different Google site, like Google.com, no matter where you are, try one of the following tips:
Click the Google.com link on any other domain.
Choose a Google domain manually by visiting the [http://www.google.com/language_tools Language Tools] page (the section with the flags).
Bookmark http://www.google.com/ncr. This is an alternative web address for Google.com that always takes you to Google.com without redirecting you.

Firefox will show 'done' on a page that is not fully loaded, how do I fix this?

When trying to axcess, any website really, it will display the word done as if the page has successfully loaded yet most of the content on the page is missing. How can this be resolved?

hello, this is currently a problem in firefox when you first close all open firefox windows and then close the application afterwards - the bug should be addressed in a later version of firefox.
as a workaround in the meanwhile you could close firefox (through firefox > quit) while the browser window is still running or try this: enter about:config into the firefox location bar (confirm the info message in case it shows up) & search for the preference named '''browser.sessionstore.resume_from_crash'''. double-click it and change its value to '''false'''.
