In the last day or two I have noticed a pop up saying " Firefox Plug-in HD Video Player is missing: " with an icon to install the plugin.

I searched around the net and found only one sight saying, " this is malware or a phishing program so do not download and just ignore. I am still able to watch movies and what not online but the message is just so damn annoying.

I am using adblock but it is not blocking that message. I am not really sure what to do. Any help would be greatly appreciated.

Thanks :-)

The Adobe flash plugin 11.5 on Firefox 12 is not installed. Neither the separate download from Adobe works nor the download for the plugin in the section "addons" or when clicking on "this web page need an additional addon klick here to install".

And several web pages like Youtube, Facebook and others ask for installing the newest flash plugin.

A few days ago, my good old FF (12) stopped downloading and saving. Actually, in the download screen it looks as if it was downloaded (shows in its full size in the Download screen), but the 'open' option is gray and it can't be found in the download folder. Also, when using 'save as' for web pages, only the html folder (images, etc.) is found where saved, but its 'mate' (the htm file) is not, and the 'open' option (on download screen) is gray. I deleted the mimetype.rdf and the downloads.sqlite files; I disabled all the relevant FF addons, changed downloading folder etc.--- nothing helps. Do you have any idea? Thanks

after mozilla firefox crashed I got a previous version of mozilla, by right clicking on to the program's GET A PREVIOUS VERSION. In the version that installed on my pc I cannont find my bookmarks

Thank you in advance

I cant open the "show all history" or "show all bookmarks" in firefox 12.0. I click on the button and nothing hapenes, I have checked all of my settings, done lots of searches and research to fix this problem and I cant find anything.

The Adobe Flash plugin keeps crashing on Firefox 12.0, and my Plugin Check link in Addons Manager directs to https://www.mozilla.com/en/404 .

Is this a hack attempt? Is Firefox 3.6 safer than the release channel?

So, for a few days now, Firefox has been extremely touchy. It would crash at random times, but now, it crashes whenever I try to type something. It has gotten progressively worse. Also, I cannot play videos, as "Adobe Plugin has crashed". This isn't just once or twice. This is every video on every site. Please help!

If it's of any correlation, I was getting bluescreens and such earlier.

1. This has gone on actually since at least Firefox 8 for many of us. With Windows 7 32 or 64bit, AND we are told OTHER OS's as well, Firefox 12 IS consuming too much memory!

When FF 12 memory consumption "hits" 800MB on a 8 GB machine, and continues to slowly climb, FF 12 has code or other problems.

2. ALSO, Firefox 12 under many circumstances, is slowing to a crawl, especially in opening windows and tabs.

NOTHING we do, inspect with memory tools, etc. seems to point to any "culprits" or guide the way to researching and potentially solving these problems...and they ARE problems within Firefox 12, and likely earlier versions.

TIME TO CLEAR THE AIR?

These are problems being seen by others, with or without any (totally blanked out/disabled) Add-On's and even most Plug-In's being disabled or removed, both for testing the problems sen in FF 12.

There IS a problem, or more than one, here, and it's not isolated or "just refer to this checklist" solvable.

There's problems, perhaps memory leaks and other agenda IN THE CODE.

We users need to stop being poo-poo'ed and "pampered" by needless communications that do nothing to truly address the problems.

Since the weekend I always, whan starting up Firefox find searchnu.com in the adress. Googling this problem did not solve it. It only happens when starting up Sirefox, not with I.E. Is this a virus, or...? How to remove it?

the adobe flash player 11 is not getting installed on Firefox...as soon as the download starts...it halts at 7%...then after about 30 seconds or so it timeouts and the installation bar suddenly shoots up to but stops at 47%....i have tried using the steps mentioned in other posts...also tried contacting adobe...but their people cant figure out anything wrong... Please kindly help in resolving this matter!!

I can't access the facebook webpage only for every browsers of my mac os X (firefox and safari), while others website are not affected. I've try so many ways to fix it, including OpenDNS, terminal, clearing caches and I even restore the caches from the trash in my laptop & etc., but still seems like doesn't work. The message is shown as below:

Invalid URL The requested URL "/", is invalid.

Reference #9.3e556acb.1338053744.2cbad993

What should I do and what cause it happens?

In addition, I feel like it happened after I clear my caches through the MacKeeper.

Thanks for helping!

I've got the most current version of Adobe Flash installed but still can't play videos that play fine with Safari. Don't know if it an extension, plug-in, or ? problem.

When I click on a video, I don't get a message such as missing plug-in or anything. I just get a page with a blank space where the video should be.

I have been a firefox fan for many versions and would like to no longer require flash. My understanding is vimeo will play video with browser that support h.264 natively. When I go to vimeo in firefox with the flash add-on disabled vimeo states my browser does not support h.264 natively. Is this on the road map for firefox, or am I missing some setting to turn it on?

I was having the same problem as other people having this link "http://www.searchqu.com/406." coming up when I opened Firefox, I read it came from AVG's latest update and I have solved this problem and uninstalled AVG but now I have a similar problem but with a different link : http://www.adoresearch.com/431

I have http://www.adoresearch.com/431 coming up when I open Mozilla Firefox and cannot get rid of it, in fact I have Google Chrome and Opera for browsers too and http://www.adoresearch.com/431 is coming up in all 3 browsers. I have read that it comes from the latest version of AVG which is my Anti virus. When I go into Internet Options it still says I have Google as my home page but it isn't when I open Firefox. I have tried back dating my computer, I have un-intalled all of my browsers and re-installed them, I have also un-installed AVG but still the http://www.adoresearch.com/431 is still there. Can anyone help please to solve my problem

I need the FireFox Setup 11.exe to go back to version 11. This is only temporary until I can figure out some problems with plugins but cannot do this on my main laptop (will debug elsewhere).

I cannot find this setup on a trusted other site, I didn't download the previous version outside the "auto update" and so don't have the installer since it was so long ago (no longer in tempfiles/recycle or wherever else windows tucks it after I use it). I'd prefer to download from mozilla directly, please direct me to it?

<whine> Why can't this be easy. :( </whine>

I have upgraded to FF12 and lost my Norton toolbar. I ran Liveupdate, but still no toolbar. I have Norton Security Suite, version 5.2.1.3, toolbar 2011.7.6.3. What do I need to do to get Norton toolbar back?

I try to share videos from fb (Facebook) and I am unable to view it when I do because the video keeps saying the video player is too small. Another thing, the windows media player is not compatible either! Why is this?!
