Chosen solution

it works in all other browsers. If I change the code, I can break this.

You might think that, but the deprecation.js library purely targets Firefox. Check line #15 in the comment block. You can confirm that by looking at the init function:

  init: function(deprecatedMethods) {
    if (!Prototype.Browser.Gecko) return;

"Gecko" is the rendering engine in Firefox and doesn't match IE or any Webkit based browser. So if it isn't Firefox, exit the deprecation library.

Hello,

Many site issues can be caused by corrupt cookies or cache. In order to try to fix these problems, the first step is to clear both cookies and the cache. Note: This will temporarily log you out of all sites you're logged in to. To clear cache and cookies do the following:

  1. Go to Firefox > History > Clear recent history or (if no Firefox button is shown) go to Tools > Clear recent history.
  2. Under "Time range to clear", select "Everything".
  3. Now, click the arrow next to Details to toggle the Details list active.
  4. From the details list, check Cache and Cookies and uncheck everything else.
  5. Now click the Clear now button.

Further information can be found in the Clear your cache, history and other personal information in Firefox article.

Did this fix your problems? Please report back to us!

Thank you.

____________________________________________________________________________

Hello,

Try Firefox Safe Mode to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.

(If you're not using it, switch to the Default theme.)

  • You can open Firefox 4.0+ in Safe Mode by holding the Shift key when you open the Firefox desktop or Start menu shortcut.
  • Or open the Help menu and click on the Restart with Add-ons Disabled... menu item while Firefox is running.

Once you get the pop-up, just select "'Start in Safe Mode"

If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, and you need to figure out which one. Please follow the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article for that.

To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.

When you figure out what's causing your issues, please let us know. It might help other users who have the same problem.

Thank you.

I tried all of suggested steps, but it did not make any difference. Our customers start reporting that they are having the same issue after Firefox pushes upgrade. That is a huge problem for us. Please help.

Thank you for the recommendation. Do you know how to do this (making sure we use all latest versions?). The site works fine on all other browsers. It used to work great on Firefox (actually, it was our #1 recommended browser) until this upgrade.

Hello,

The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Note: This will cause you to lose any Extensions, Open websites, and some Preferences.

To Reset Firefox do the following:

  1. Go to Firefox > Help > Troubleshooting Information.
  2. Click the "Reset Firefox" button.
  3. Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
  4. Firefox will open with all factory defaults applied.

Further information can be found in the Refresh Firefox - reset add-ons and settings article.

Did this fix your problems? Please report back to us!

Please check if all your plugins are up-to-date. To do this, go to the Mozilla Plugin Check site.

Once you're there, the site will check if all your plugins have the latest versions. If you see plugins in the list that have a yellow Update button or a red Update now button, please update these immediately.

To do so, please click each red or yellow button. Then you should see a site that allows you to download the latest version. Double-click the downloaded file to start the installation and follow the steps mentioned in the installation procedure.

Hi conspiritech, the original problem in this thread had to be fixed by changing the website. I suspect you have a different issue, although perhaps it only occurs on particular websites. If it recurs, could you start a new thread and make sure to tag it with "mobile" so it is spotted by the volunteers in the best position to help? You could do that here:

It has actually stopped, apparently without my intervention. I did have a notice when I tried it just now that my '[privacy]defense' plugin trial (?) expired.
