I was regularly using Foxit PDF reader plugin to view pdf files inside Firefox browser before the pdfjs plugin came through. After that I have disabled the pdfjs plugin (through about:config) and tried many ways to get back to viewing pdfs in the browser using the Foxit plugin but nothing works. I have reinstalled Firefox, reinstalled the Foxit pdf plugin.

When I go to Options > Options > Applications, I cannot see the "Portable Document Format" option on the left column. There is Adobe Acrobat Forms and XML and there is "Foxit Reader Document" (presumably PDF) and "Foxit Reader FDF Document" - I want to change those opening actions to Foxit inside Firefox, but there is no such option either - so Firefox can just download the file and then open in the external Foxit reader, but not inside it.

Any help to resolve this is appreciated. FF 21, Win 7.

In the last few weeks, a lot of my Firefox windows hang for long periods of time - a minute or more. Today it got much worse, where it would hang for ever (defined as many minutes until I got tired of waiting and killed it).

After trying many things - It appears to be Javascript related. If I disable javascript - all the sites I go to first complain that javascript is not enabled butthen offer me a javascript free version. I have no hangs with java script disabled. a few sites just won't work with out it - but still no hang. As soon as I re-enable javascript - all my windows hang. I have tried only having a couple tabs open but still they hang. This happens with google mail and Yahoo mail as my base two. But if I open several other windows instead, they hang as well.

I tried downgrading to Firefox 17 - no help there.

I tried updating flash, I tried downgrading flash. No difference.

I have run out of ideas on what to do here.

This past few days syncing of both my desktops simply is not working. When I go to history it only shows the history of the computer I currently work on. In Sync options on both computers everything is set and ok. All of this worked until last Friday the 17th. So please either help solving this issue either tell me what to do.

Thanks, Andrej

When opening sites such as twitter and some other sites the screen goes fuzzy with horizontal black lines. When this happens you can't read the anything on the screen. Other browsers have no problems such as this.

Here's a pic for you

I use right click constantly to open links in a new tab. Sometimes when I right click, it does a left click and a right click at the same time. I will click a link, and instead of opening in a new tab, it will open in the current window while briefly showing me the right click menu as the new webpage loads.

I am having trouble getting Java to work in Firefox (Opera too) on Mac. http://www.java.com/en/download/installed.jsp?detect=jre tells me "We are unable to verify if Java is currently installed and enabled in your browser." Notice that when I access the page, Firefox wants me to activate Java in a pop-up. I did this.

I know that Java is installed because I can open the Java Control Panel. The setting "Enable Java content in the browser" is checked and Security Level is set to High. I have tried setting the security level to a lower setting, but that doesn't help.

I have verified that the Java plugin is enabled. I have tried clearing Java cache via the control panel - no luck.

I realise that Apple has blocked Java according to this article: http://appleinsider.com/articles/13/01/31/apple-again-blocks-latest-version-of-java-through-os-x-anti-malware-system. I have been able to get Java to work with Safari (this doesn't help for Firefox) by editing the file /System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/XProtect.meta.plist, but that is only a temporary solution, as it shouldn't be necessary to do this edit.

Version details: Mac OS X 10.8.2 Firefox 18.0.1 Java version 7 update 11

I can see how to clear cache by going to Tools-Options-Adanced and uner Cached Web Content click on Clear Now.

Underneath that there is a box which says Override Automatic Cache Management. Underneath that is a greyed out line which says Limit Cache to 350 Mb of space.

If I tick that box will my problem be automatically solved so I don't have to manually clear cache when I have a problem with embedded pictures etc in an email I have received?

I hope my questioning is clear. I am certainly not an expert at computers and I try to solve a problem without having to bother you with a question but in this instance I can't fuind an answer to me question.

Thank you for your help.

All of my search engines in the toolbar of Mozilla have changed to UK sites!! In "Manage Search Engines", I clicked the "Restore Defaults" button, but all I get is search engines for the UK. I clicked the "Get more search engines"button, but nothing I want is listed. (Yahoo.au, etc)

How do I fix this???

Thanks a lot Sonia

Automatic updates do not work behind proxy on Windows machines. Fix this Alot of applications can do this but neither Firefox nor Thunderbird can. Noone cares for your stupid decisions about FirefoxOS replicating ChromeOs which is money on the wind as well. But why not do something useful for ........

Yes i know, linux doesn't have this problem and its ok there but microsoft isn't so generous thats why many companies have to think of dirty way doing things. Thats the only thing i ask, one more dirty thing for dirty os, thanks.

I'm running Firefox 20.0.1 on Win7 x64 and all of a sudden, all JAVA-scripts freezes and i can do nothing but wait. After about 30sec i get a message saying that...

'A script on this page may be busy or have stopped responding. You can stop the script now or wait for the script to complete' (or similar).

I get the message in Swedish so it's roughly translated. I included some screenshots of the error (all from different pages).

It works fine in safe mode and when i disable JAVA. I can't think of anything more right now, and i actually need to write this message using Chrome because i can't get here using Firefox anylonger.

It sucks and really need your help. Thanks!

When I use to open the Bookmark Menu, in the past, there was a number displayed that showed the number of bookmarks. This stopped happening a week or two ago. How can I easily, automatically get this information? Thanks.
