Since installing the latest update, Firefox will not load; it gives me the following error -- XML Parsing Error: not well formed.

since installing the latest update, Firefox first operated with some errors but now will not load at all; it gives me the following error --
XML Parsing Error: not well formed
locations chrome://browser/content/browser.xml
Line Number 1191, column 20:
utton id="back-forward-dropmarker" type="menu" chromedir="&locale.dir;"-------------------
please note that the words "utton ID" are exactly as the error message gives it; and at the end of the message there are exactly 19 hyphens.
I don't know why this faulty code is referencing things to do with "chrome"... the Chrome browser is not installed on this PC or anywhere on our network.
Also, this is not the first problem I had after clicking Firefox's prompt for the latest update. Before Firefox retreated into this error message, it was loading but running with some faults...
1. the bookmark symbol was not appearing on the right hand side of the URL line, so I had always to click on "bookmark this page", after which the bookmark symbol did appear; however I don't know if the bookmarking function worked properly.
2. the back and forward buttons were not highlighted, as if I had not come from a previous page; so once I clicked on a link to a new page I could not go back to where I came from because Fiefox thought I hadn't come from anywhere.
3. there may have been other errors, but I did not find them.
How do I reinstate my Firefox program to work properly please? do I have to download the latest version and reinstal? if so, do I have to remove the old version first? or is there a fix?
Even to write this message I have been forced to use (yuk -- I don't like to say this!!!) Internet Explorer. So please -- I need help urgently.
Thanks,

I hope that solves your problem too.

Since installing the latest update my mother-in-law gets Error Code VM502 when sending to only 6 recipients. This didn't happen before the update.

The error came from your providers server. You need to ask them why they are setting limits.
Thunderbird does not have any limits.

Contact Whatsapp for support.
There is no logical expectation for Whatsapp to be listed under location services or for that to have any affect on what the app can access.

Since installing the latest update of Photoshop CC two days ago, Auto Blend for focus stacking is selecting all pixels from the bottom layer instead of selecting the ones in best focus from each layer. Has anyone else seen this problem?

I installed the latest update of Photoshop CC two days ago on my Macbook Pro, and now when I try to do focus stacking by opening multiple photos and doing Auto Align and Auto Blend, the blend selects the entire bottom layer instead of selecting the in-focus areas from each layer. I even tried again on a series of images where this worked a week ago and the problem occurs. I have Photoshop on a Windows 8 machine and did not apply this latest update and it works fine. Has anyone else encountered this?

And since installing this same update, my Photoshop is crashing just after starting.
Ashutosh.Nigam suggested me in this forum to change the permissions to SLStore & SLCache Folder, but it did not work.
Ali from french Adobe support told me to delete my Settings files, but it was not enough.
A girl with no name from the same team told me to update my video card driver, but you know I run the latest Mac OS X version and everything is updated, mademoiselle.
Stephane sent me a link to a huge page of things to do :
- Troubleshoot account-specific fonts, but there wasn't any corrupted font
- Delete account-specific Adobe cache files but... guess what...
- Troubleshoot account-specific login items but... yes, that's it, I can see you understand me
- Reset the access settings on the user account's Library folder... oh god, that was fun, I used the Terminal and sudo commands
I did all of these things because when I tried to open PhCC in an other admin session, it worked, so that was an incompatibility between my session and PhCC. But, but, but, when I tried again to lauch the app in the second session, it worked fine but refused to quit. Ha ha ha.
So you can try to delete your Settings files. I wish it'll work for you. If not you can try the long list above... or hope a better answer from the support.
I didn't change anything but Photoshop on my session and they ensure that the bug is due to my session and not to their update. Strange affair.
Good luck,

Since installing the latest update, whenever I try to play purchased videos, they open in the separate video window and immediately causes iTunes to crash and close.

Ever since installing the latest iTunes 10.4 update, I've been having trouble playing purchsased videos. When I try to play them, they open in an unseen new window and after a couple of seconds of audio, iTunes crashes and has to close. There isn't something wrong with the videos as they play fine on my iPod and I have played most of them before, but they just won't play in iTunes suddenly.
Can anyone help?

With the newest updating I lost all music I had bought or loaded from cd's

Hi, I uploaded to Iphone 4 with the the newest update and all music disappeared both from my Macbook and iPhone. The icons are there but I can't play anything from the old material. I uploaded a new song which I can listen without problem? I use iCloud but don't know how to pick old files from there...if they are there anymore?

I started having this issue yesterday too. I just downloaded the latest iOS update 7.0.4 hoping it would fix it, instead I'm left with a very very old version of the playlist when I access my iPhone directly, but iTunes still shows the newest playlist version even if the songs aren't playable. Plus the songs are located under Music, but aren't playable - I get an exclamation mark beside the song.
When I export the playlist from my iPhone and try to import it back into iTunes, it tells me some of the songs could not be located, even though I went and re-added my entire music folder back into iTunes and I'm getting the exclamation mark next to new songs I know are in my folder.
For the last year I haven't bothered making my playlist in iTunes, I generally just build the list right on my iPhone. Since I've changed computers in that time I don't have the source for some of these files, and my phone created a new backup before installing the 7.0.4 update.
Ever since iTunes went from version 10 to 11, its been nothing but problem after problem. At this rate, I don't see the new iPhone in my future if this continues. At the moment, I'm ticked enough to cancel the iPad Mini 128GB order I made yesterday, if there's no fix coming.

Never mind Restored my phone and got my contacts back!

Since installing the last update I am getting warnings through AVG that friefox is using excessive memory - 215 MB. Please provide input as to whteher this is a matter of concern becuase the window is coming up constantly.

I am on a dell 620 laptop. Every time I get on Firefox, an AVG window is popping up saying that excessive memory is being used (215 MB) and it recommends that I log out and log back in for faster processing. Logging out does not make a difference. The last update also disabled my AVG tool bar from the internet screen which I am not sure matters much, but I am concerned about the excessive memory use warning. Can you please provide me guidance about this matter?

Thanks but I have no idea how to do that and don't know the purpose of the add- ons or what is considered critical in the updates so that is outside of my knowledge level and comfort. How do I find out what is critical in the update without devoting a major chunk of my life to it? This is getting frustrating from my perspective. I am going to contact AVG and ask them how this pop up is gauging what to interpret critical memory use. If you have any other thoughts they are appreciated

Since installing the new update videos keep on flickering when I stream them. How can I fix this?

Ever since I updated Firefox the videos I watch keep on flickering when I stream this. It is true of youtube, and other mediums. This is not a problem when I watch videos on Safari or Internet Explorer. I have uninstalled and reinstalled firefox to no success and restarting my computer has not helped either.

Since installing the latest update firefox stops responding and hangs during use.

The only way I can get it to work is to shut it down and restart the application. I can open IE and access the sites which don't respond so it is definately a firefox problem. All firefox tabs stop responding including downloads. This is occurring every 2nd or 3rd page I open. Help - it's driving me insane!
