Since updating to Adobe Reader 10.1.3, I noticed Firefox 11 does not display PDF files. It just shows a blank screen.

The only workaround I found is disabling the Adobe Acrobat NPAPI Plug-in (ver. 10.1.3) the update installs. Firefox will prompt which application to use.Choosing Preview allows the PDFs to display correctly.

Neither Chrome or Safari exhibit this behavior, nor does Firefox 11 (Windows) with the update installed.

Has anyone else experienced this?

When I use FF 4.0b7 on my Mac I try to go to a website using flash (YouTube, Hulu, etc.) and it doesn't display anything. No video, nothing. But when I use FF 3.6.12 any website using flash works just fine! I've reinstalled Firefox and flash many times over, to no avail. Flash also works in other browsers, just not Firefox 4..

The Silverlight plugin crashes every time i try to watch a video at the Universal Sports website. I have uninstalled this plugin and re-enstalled it many times with no success

I have an issue with one of my Firefox extensions/plugins, it's called MyStart: Incredibar, and I basically installed unintentionally when I installed a program with a Brothersoft downloader/launcher. I tried uninstalling Mystart and I tried permanently stopping the service that updates the MyStart incredibar plugin. What it basically does is, when I open a new tab in Firefox, it opens some sort of website, I don't have a problem with it loading a search engine, the only problem I have regarding the search engine is that every time I open a new tab, it actually loads a new page. I even tried resetting the certain figures in about:config which helped temporarily, but after I restart Firefox then it still runs the search engine when I open a new tab. I use Eset Nod32 and Anti-Malmwarebytes as my system's defense, and I've tried scanning with both of them but they don't help at all, does anyone have information that will permanently remove this plugin from my PC?

My About:Config settings looks like THIS

Plain and simple. An app for my university (student) which requires Java Desktop 6.0.2.9 no longer works. It's only since the install of FFox 8 and since it uses Java I can only assume the incompatibility with Java Desktop 6.0.29 is the problem.

Where can I download a copy of FFox 7 until this issue is resolved.

I upgraded to FF 4. The Norton toolbar 5.5 is incompatible. I want to know if I am still protected by Norton while browsing even though the Norton toolbar is not installed. According to the Norton settings, the web protection is on and working. If I am still protected I will wait for an updated Norton toolbar to be available, otherwise I will need to know how to uninstall FF 4 and reinstall FF3.6.

ChatVibes is a new plugin that is supposed to allow you to video chat on facebook. my wife invited me, so i clicked on it. now i have this stupid toolbar that i have to disable every time i turn on firefox. there is no program listed on my computer, and no addon listed in firefox.

I am attempting to watch an NFL game on channelsurfing.net. I downloaded Firefox successfully but was communicated that I will require vshare plug ins to initiate. I downloaded vshare, but was informed that it was a windows product. What next?

The Real Player Browser Download Record Plugin 15.0.1 in Firefox 10 stopped appearing on all videos. It was working from 1/31 to 2/3 and now doesn't show at all. A clean reinstall of Real Player 15 Plus doesn't fix this. OS is Windows 7 Home Premium. As usual after a F.F. upgrade, the download button works on Internet Explorer. Now it's the weekend and Real's Developers aren't even working! The Developers of both companies need to coordinate this once and for all. Norton started doing this with Mozilla at my suggestion for the Norton Tool Bar and there no longer is any delay in compatibility. Please contact Real Player tech support to complain. Their Case Manager told me that the three week compatibility delay with Real Player 14 last year would never happen again. I wouldn't bet on it.

  Update Note: This thread is now also about "Adobe Flash 11.3 doesn't load video content"  because people having that problem started posting here.

I am currently running Firefox 3.6.12 on Windows XP on an Acer laptop. Adobe Flash Player won't work through Firefox and sites say: "This plugin has been disabled" or "You need the latest Adobe Flash Player"-- I have updated it every time (changing the player version to "Other Browswers"). Flash has proven to work in the past but I'm not sure why it no longer does.

Also, I get this Error every time I open Firefox. I have to attempt to open Firefox 3 times in order for it to finally open because of this error:

getPlusPlus_Adobe_reg.exe - Application Error The instruction at "0x00000000" referenced memory at "0x00000000". The memory could not be "read". Click on OK to terminated the program

Flash is however, working on Internet Explorer. I have tried uninstalling every Flash Player and reinstalling it for Firefox. I've resorted to enabling every video type of player on Firefox in an attempt to get videos and games working...

I have an epad signature capture pad and am working on programming my website to work with it, but I could only find an ActiveX control to use with a browser. Since FF doesn't use ActiveX I contacted the manufacturer and they said that is a custom programming issue that they do not want to mess with. Does anyone know where I could get an extension or plugin so I can use my epad with FF

DivX Plus Web Player HTML 5 [video] is incompatible with Firefox 4.0b8. <=(disable reason) So i can no longer stream my fav movies. Also, when i click play, sometimes my trafic bar goes crazy like it's downloading from the source, but i have no image or sound just like the divx web player is crashed. So please can you help me? The web player worked on FF 3 and on Opera...

Also, Bitdefender Antiphishing Toolbar, Cooliris and some Microsoft Framework stuff are incompatible with Firefox 4.
