I've tried uninstalling and reinstalling firefox. I have a pc and use Windows Vista. Please help! Thanks!

A possible cause is security software (firewall,anti-virus) 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 and the plugin-container 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 and the updater process.

  • I can't access the internet with Firefox on my computer (Windows 7 PC). I have used Firefox as my browser for 1 year but 5 days ago it stopped working even though Internet Explorer worked fine. I can't solve the problem and need some help.Randy Brown

    September 26, 2011
    Dear Mozilla,
    I am having some difficulty accessing the internet with Firefox on one of my PC computers. I normally use Mozilla Firefox as my web browser and google is my homepage and gmail is my email system. The operating system is Windows 7. For over a year this system worked perfectly but a few days ago it stopped working. When I launch Firefox now I get the message that that website (www.google.com) is unavailable. In fact, I can’t access any website and I am blocked from the internet entirely within Firefox. My internet connection is fine because Internet Explorer works fine. I can access google and any other website within that web browser. I have investigated all the security issue I can manage and found no smoking gun. I’ve tried uninstalling and reinstalling Firefox to no avail. Is Windows 7 compromising the effectiveness of Firefox? Any suggestions or other assistance you can offer would be appreciated.
    Sincerely,

  • I have used Firefox on my computer for several years. Today, after upgrading to the new version, I was not able to open Firefox. I have tried several times uninstalling and re-downloading Firefox. It still will not open! What is wrong?

    I have used Firefox on my computer for several years. Today, after upgrading to the new version, I was not able to open Firefox. I have tried several times uninstalling and re-downloading Firefox. It still will not open! Is the new version not compatible with Windows Vista?

    I hope that link points to mozilla.com or mozilla.org
    You will have to close firefox.exe with the Windows Task Manager from the "Processes" tab of the WTM since you don't have a widow to close.
    The best way to close Firefox is through File > Exit, for those who stuck with the "Firefox" button click on the Firefox button then Exit. It is not perfect but it is a lot better than just closing the window with the "X" in the upper right corner

    I have Photoshop Eleent 12 and use a Windows PC.  I hae been using a Canon EOS 50D for several years, which uses a Compact Flash Card.  I have always downloaded pictures by using a card reader wich I connect to my computer. I Go to the Organizer, click on "Import" and select "From camera or card reader".  Once on the Photo Downloader, I select the pictures, chose the folder and click on "Get Media" and all the photos get downloaded. Today I folled the same procedure as always, but ZI'm gettig an error message that reads"Import Failed" followed by another message that reads "Nothing was imported. The file(s) or folder(s) selected to import did not contain any supported file types, or the files are already in this Catalog."  I'm puzzled by this message and don't know what to do o get my photos.  Any suggestions?

    The organizer doesn't care where you send your photos when you download them via the downloader or where they happen to be when you first bring them in if you use the Get Photos command, but once your pics are in the Organizer, you *must* move them from within organizer or it can't find them. You don't have to use My Pictures at all if you don't want to, but regardless of the folder where you put your photos, if you want them someplace else, you use organizer to do it.

    Wow, Karan Taneja, you've just embarrassed yourself on a worldwide support forum.  Not only is your post ridiculous and completely inappropriate for a technical support forum, but it also shows your ignorance as to whom you think the audience is.  Apple is not here.  It's users, like you. 
    If you would have spent half the time actually reading the Terms of Use of this forum that YOU agreed to by signing up to post, as you did composing that usesless, inappropriate post, you (and the rest of us on this forum) would have been much better off.

    Is there a phone number to call Adobe.  I go around an endless loop pressing their contact info tabs?  Maybe someone at this sight can help. I am new to digital photo - I have been a B&W film photographer for many years. I have a problem with a Macbook Air.  It was working fine - I was using LR and a message came on the screen that said something like the memory was dangerously low.  I stopped and tried to delete LR files.  I couldn't do it.  I closed the program and tried reopening and got the message that there is not enough memory available to open LR.  I contacted Apple.  They spent a half hour on the phone with me and eventually told me they didn't know how to help. The tech said that LR had gobbled up all the memory and said I should contact Adobe and ask where and how my photo files are stored and to delete them.  I have several back-ups.  Thanks - Arthur

    This sort of error message only comes up for Lightroom when your hard disk is full. Indeed this has nothing to do with internal memory as that will be intelligently be dealt with. If you have a mac Book Air that is not so surprising as the cheapest versions come with very small hard disks and if you shoot raw with any recent camera, you'll fill up your hard disk very quickly and you can probably only store a few months of pictures if you are a typical photographer. So the bottom line is that you need to create some room on your hard disk. You should move some of your originals to an external hard disk. You can also delete some of your backup copies of your catalog file that Lightroom automatically generates every few days and that quickly gobble up hard disk space. So first figure out how full your hard disk is. To see that, go to the apple menu, hit -> About this Mac -> More info->Storage. You should see your internal hard disk on top and you'll find that it is almost entirely full with photos. Now find your Lightroom catalog file using Finder. It is usually in a folder in the Pictures folder in your home directory. You should see a Lightroom 5 Catalog.lrcat file, a previews file and a folder called backups. Inside the backups folder, you'll find a lot of subfolders. They have names that show the dates the backups were created. If you have backups of your entire hard disk, you can delete these backups when they are older than a few months. I usually only keep the last 4 around. Just drag the folders into the trash can on the dock on the bottom of your screen and empty the trash. This will probably free up enough space that Lightroom will already run again. Now start thinking about where you will want to store older images. If you have a good USB3 or Thunderbolt hard disk that is probably the best option. There is a video here by Adobe that has some instructions on how to do this: Is Your Hard Drive Full? Here’s How to Move Images to Another Drive in Lightroom. « Julieanne Kost's Blog If that doesn't work because you don't have enough hard drive space to run Lightroom yet, here is another set of instructions to move your files using the finder to the other hard disk: How do I move only my photos to another hard drive, leaving the catalog where it is? - The Lightroom Queen. If you follow that, as soon as you confirm all your images are on the new hard disk, you can delete them from your internal one. She is not so clear about that part but if you don't delete the originals that you moved off you don't free up space. You should move the folder structure over to the new hard disk and then reconnect the folders in Lightroom. That should make it refind all your images.
    That said, if you are uncomfortable with the computer in itself, your best bet is to find a local photography club. There is invariably a Lightroom savvy person in there that could help you move your files. That might be your best bet if you are uncomfortable moving these yourself. A general mac savvy person like you would find at an Apple store or so generally will not be able to help you with this except when they are photographers themselves and know Lightroom. You might get lucky with that.

  • Since upgrading to Firefox 27.0 some webpages will not load when I click on them. It gives me a message saying that Firefox can't find the server.

    Since upgrading to Firefox 27.0 some webpages will not load when I click on them. It gives me a message saying that Firefox can't find the server. I have to click the link several time before it will load and sometimes when they do load it does not show the page right. It is like the HTML is messed up or something. I have tried everything I can think of. I started in safe mode, still did it., I removed add-ons, still did it., I reset Firefox and still did it., I completely uninstalled Firefox and re-installed Firefox and it still does it. I have tried Malware Bytes Anti-Malware scans and Avast boot-time scans and found no malware or viruses. I have found that those websites open the first time with no problems on my IE9 and they used to do so in Firefox 26.0. I'm at my wit's end. The website links are in my bookmarks and are used all the time so they are trusted and my avast is set to allow them. They range from news websites to gun websites and everything I have read says that Mozilla does not filter those unless something has changed recently.

    Firefox 6 will not load when I click the icon. I have tried to uninstall it, both through the control panel and going straight to help.exe. In both cases nothing happens. How do I uninstall this program?

    Start Firefox in [[Safe Mode]] to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
    * Don't make any changes on the Safe mode start window.
    See:
    * [[Troubleshooting extensions and themes]]
    * [[Troubleshooting plugins]]
    If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
    * Use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.
    * Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

  • I have been using Adobe Photoshop Elements 11 for two years. I got a new printer and installed it although I did not remove my old printer from my computer. I used this program and my new printer for quite a few months, but today I deleted my old printer

    I have been using Adobe Photoshop Elements 11 for along time now. When I first used the program I had a different printer than I have now. Although I changed printers I never removed the software from my old one. Now this was never a problem until today. When I choose a printer I still had option to use the old one but always chose my new HP Envy 5530 and Adobe never had a problem printing from that new printer. However today I decided to remove my old printer from my computer and now my Adobe cannot find my new printer.  How can I make it find the HP printer?

  • I use an app that has tabs. (I do not mean tabbed browsing) Yesterday FF worked fine, today, it will not respond when I click the app tabs. IE still works fine on the tabs in the app.

    FF does not respond to the click when I click certain areas in an app that I use such as a tab, or OK button, but will work on other buttons that I click.

    Hi,
    2 things:
    1. Assuming your script is original - it is not asking for a TXT file till it is found in expected location. You can choose between 2 solutions:
         to remove FindChangeList.txt from FindChangeSupport folder ==> script will ask for another file
         to override this file by your query ==> script will not ask but execute your query
    2. You can see greyed TXT files in Script Panel since this panel shows executable files (script's formats)

  • NFirefox will not allow me to click on a link without switching to another program first. The version is 3.6.8. This problem makes Firefox virtually unusable. Help!

    Firefox will not allow me to click on more than one link in a sequence. After one click, I am forced to switch to another active application before returning to Firefox and clicking on another link. I have seen this problem posted by others, but I can't find an answer by Mozilla. Since this problem makes Firefox virtually unusable (version 3.6.8) I would hope that Mozilla would offer an answer ASAP. Until then, I'm stuck with Explorer.
    == This happened ==
    Every time Firefox opened

    Do you have that problem when running in the Firefox SafeMode?
