Whenever I visit a page that contains even the smallest of Flash objects, Firefox stops responding briefly and then a dialogue pops up to say that Shockwave Flash has crashed. I have tried all of the fixes I have found on other questions: I have reset Firefox, run it in Safe Mode, disabled all extensions, reinstalled both Firefox and Flash, downgraded both Firefox and Flash and turned off Flash's "Protective Mode" etc. The problem only seems to have come about after I upgraded to Firefox 20 yesterday if that is of any help. Flash also crashes on IE and doesn't work properly on Chrome (YouTube does not play sound for example). I have run out of ideas and I was wondering if anyone has anything that I could try. Thanks in advance for any answers!

When I install the latest version of Flash Player(11.6.602.171), I get a firefox plugin. Why am I not receiving the Flash Player instead? OS is vista home premium, firefox v.18

I was lissening to online radio. Firefox needed to update. After the latest update the windows media player plugin dissapeared from the add-on list, while still being installed correct. I reinstalled it, but that didn't work. I replaced/deleted some files in firefox as suggested for similiar problems, but that didn't work either. Now I can't play wmp files anymore on firefox.

I hope u can help me solve this problem.

My mobile's android version is 4.1.2. At the present time, I cannot watch and download any youtube videos. If flash player doesn't support any mobile using android version over 4.0 , how can I watch and download these flash videos?

I am now getting the 'well this is embarrassing...' message EVERY time I open Firefox; I have my Home page set to always open 9 tabs - these are the SAME tabs I have opened at start-up for about 2 years - WHY this annoying message now?! When I click 'close' the Home page opens with all the tabs with no problem, but the message is really irritating & doesn't seem to be telling me anything, as there isn't a problem with any of the tabs? NB: In case you ask 'why 9 tabs'?; these are essential websites I use every time I am browsing/working; I cannot keep opening them manually every time. Please advise why this message comes up as here seems to be no problem, & how I can get rid of it? Thanks.

More and more frequently, when I open a web page, the text is distorted. If I place another window over the text or highlight it, the distortion disappears. If I scroll the web page, the distortion scrolls with the text.

I've attached an image. Does anyone know what this is or how I can fix it?

I am currently using Firefox 21. Since the 19, the "clear history" function in Firefox history menu has disappeared. So no way to click on it and clear history as desired, last hour...or everything. I have uninstalled and re-installed the browser several times no change. Only way to clear history is by deleting manually on the left side of the window after doing Ctrl+H. Is there any way to fix the browser?

For the last few days my Firefox does not display the downloads window. I have tried to follow the suggestion set out in Firefox Help ie Tools --> Options --> General

But my General Tab doesn't show under Downloads the option to check the box "Show the Downloads window when downloading a file". Under Downloads, the only option shows "save files to Downloads" and "Always ask me where to save files".

Any suggestions on how I can get to --> Downloads the option to check the box "Show the Downloads window when downloading a file".

Thank you in anticipation

3 days ago I was trying to watch videos on youtube and i kept getting adobe flash player crash error. i went ahead and updated to firefox 20.0.1 and i updated to flash player 11.7. still getting the error. Ive clean installed both since. I've reverted to older versions even the 10.3 listed on Firefox Troubleshooting guide. Nothing seems to work. I cannot watch any video period on any website that i've tried. Ive ran Malwarebytes and virus scans both with latest definitions and all is clean. Now firefox just crashed as i was writing this. weird. some assistance would be appreciated. Thanks

After Upgrading to FireFox 21 my browser no longer can detect that I have the Citrix ICA Client installed and prompts me every time I attempt to launch an .ica file from the internet. Upon multiple installs of the ICA Client from the prompts including Uninstalling it completely then reinstalling it I ignored the prompt and tried to launch the .ica file. It will launch only 1 .ica window no matter how many .ica files I click on. (Firefox 20 would allow me to launch several citrix sessions at a time.) Also when the 1 citrix session is open if I minimize it or bring another program to the foreground the .ica window becomes black and is no longer usable since you can no longer see anything in that window. Is this a known issue?? Currently I have had to unistall version 21 and found a version 20.0.1 that Ive installed disabling the automatic updates.

Firefox 20.0.1, windows 7, flashplayer up to date.

Certain youtube videos won't play. The advert beforehand plays, and then the video just displays a black screen, no loading, trying to skip to a later time in the video doesn't work. It seems to be certain youtube users whose videos won't play, users whose videos I was able to watch only yesterday. The featured video on the user's channel is watchable, but not when opened separately. IE won't show the affected videos either.

When I updated to Firefox 21.0, I found that Flash Player Plug-in 11.7.700.202 was not working. Videos would not play. Had no problem before the Firefox upgrade. I downloaded a new copy of the player but the download would not complete. A error message (only a single instance of this application can run) appeared. I used Adobe Flash Player's uninstall to delete all Flash files. Then I tried downloading Flash 11.7.700.202 again. Same error message appeared and would not finish the download. Chrome videos work with no problem. Is there a hidden Flash file somewhere that's conflicting? Is this a Mozilla bug? I looked at all the support topics and didn't find anything. Any help would be greatly appreciated.

Greetings! I've downloaded a program and here was some virus, now i alway have this page http://searchiu.com/?affil=141 as a start page and i'm afraid of my security. Can you help to remove this virus and get back my start page? Thanks you!

My desktop is running Windows 8, which recently crashed. Since then, every time I start up, Firefox 17.1 (which is in the startuo folder) does not load, but brings up an error window saying (Couldn't load XPCOM). Dismissing the window then allows me to start Firefox myself. I have uninstalled Firefox (but not the personal stuff), downloaded a new copy of Firefox 17.1 and re-installed.... same thing happens.

Just to clarify ..... this only happens once, following the initial boot up of the desktop. I dismiss the error window and all is well after that.

Any bright ideas please?

What is XPCOM referring to? A missing dll file? can I find this file elsewhere and move it to the correct location?

Many regards.

Since I've upgraded to Firefox 19.x, font rendering has been completely broken. Fonts are all messed up, distorted, etc...

See here: https://support.cdn.mozilla.net/media/uploads/images/2013-03-07-20-12-39-1f0313.png

I've read through many suggestions about changing options in about:config, and various other settings, but nothing seems to work.

The browser is totally useless like this.

Any help on how to fix the font issue would be greatly appreciated!

Is the latest Java 7 update 17 safe to enable now? I noticed after updating, it was still disabled, but no longer blocked in red by Firefox. My assumption is that it's safe, since not "in the red" currently. However, I'd like to be sure before I re-enable it. Thanks!

Currently loving Firefox 19.0 on WinXP SP3

The Issue.... Coupons.com plugin disapeared after upgrading FF to v21 (from FF Help Menu>About) I then was prompted to install the plugin when i went to print a coupon from coupons.com... the installation shows it succeeds with no issues, however the plugin is still not showing in the plugin list, and of course coupons don't print (You are prompted by coupons.com to download the plugin...over and over again)

How it happened..... I almost never reboot the PC. Before today everything was working fine. I didn't reboot PC, but decided to upgrade FF to latest version (previous was 20.something)... because i was getting a really long (and context insensitive menu when right clicking anything).

The upgrade appeared to run flawlessly, but then the issue with coupons.com became apparent, and upon a quick look in about:plugins, i noticed the coupon.com (coupon printer) plugin is no longer there....

I closed all browsers, uninstalled the Coupons.com plugin (from Add/Remove programs), and verified that Internet Explorer can't print coupons anymore from coupons.com. Then i reinstalled the plugin (from coupons.com) and Internet Explorer was once again able to print coupons. This means the plugin is being installed on the PC, and while Internet Explorer works, Firefox doesn't (since this version 21)

I have Firefox 18. I have the latest Adobe Flash installed (after doing a full uninstall and reinstall). I have cleared the cache, cookies, etc.

No matter what I try, YouTube videos will not play in Firefox. I always get the same message:

"An error occurred. Please try again later."

If I copy the exact same link into Explorer (which I normally detest using) it plays perfectly. So clearly the fault lies with Firefox.

What can be done to fix this bug?

I turned on my notebook this morning to find Private Browsing on and Firefox reset to the default appearance. I can't find out how to turn this browsing feature off! Read the articles, looked at Community forum ... nada. Please help! I want my own Firefox back!
