I downloaded and installed firefox 5, but uninstalled it because it is not conpatible with Real Player video downloader. I cannot download videos from You tube or other sites with Firefox 5. How can I resolve this problem? ooader

I use Real Player to play music and videos. I also download videos from You Tube and from other sites thru Real Player which is compatible with Firefox 4.0.1, but not with Firefox 5. Please tell me why?

Firefox 4.0.1 has been an unsafe browser since the release of Firefox 5. So please don't use it.
Real hasn't made Real Player Browser Plugin compatible with Firefox 5.

My Lingualeo add-on works wrong with latest versions of Firefox

Hi! This add-on allows to translate English words into Russian and remember them to study later as shown in attached screenshot. After latest upgrades of Firefox it doesn't show list of possible translations, so I can't pick any translation and remember it. I have installed Firefox 34.0 and this fixed my problem. Can I do something to make lingualeo work properly with latest version of Firefox?

Sorry if my formulation was incorrect. I'm not a developer of this add-on, I'm just its user and it helped me to study English :) Can I do anything as a user (except downgrading Firefox)?

Problems with latest version of Muse

I'd like to report some problems with latest version of Muse. Its actually all related with scroll effect.
1. In previous version I had a group of rectangles and when I added to them motion (initial motion: 0 everywhere, final motion: 0 everywhere) they where sliding nicely down during scrolling my page, and it happened only in y line (horizontally). Now its moving also on the right and left, when I am changing size of window. Other thing is that in firefox this group of rectangles is pinned to bottom of window.
2. I have footer that I want to be always pinned to the bottom of window. The footer is a group of objects: rectangle + one png file with hyperlink, and one text with hyperlink - and of course it worked perfectly in previous version, but now finally when I export the page I have only the rectangle without hyperlink on the bottom of the page and the rest is missing.
I hope I explained it clearly? I did my best :-)

I have a same problem like no.2.
Finally, I fixed it.
First, You have to ungroup the footer objecs.
Second, Group again that.
Then export your site.
Please try this!
I hope this will be of some help.

How can I download videos from youtube with may MacBook Pro? I cannot download with real player. So how can I do it?

How can I download videos from youtube with may MacBook Pro? I cannot download with real player. So how can I do it?

There are two apps that I know of - and I would also swear that they come from the same developer, although they've different names. Both have free trials and both cost $40 (but both do 'other' video conversion as well).
One is WonderShare - I bought this one and it works very well for downloading YouTube videos as well as converting just about any file format you can think of.
The other is iSkysoft Video Converter (just noticed that it's now $36).
I tried them both and finally decided on WonderShare. Give them both a trial run and decide if you like either one enough to buy it. I don't know of any 'free' software that will allow you to download and convert YouTube videos, but perhaps someone else will come along and know of something...
Good luck,
Clinton

After updating to latest Firefox - when I click on google taskbar my CPU usage goes to 100% and stays there... and computer is really slow. No other search engine show the 100% usage like Google. There was NOT a problem with older versions of Firefox...?

My computer got really slow after updating to latest version of Firefox. I checked all processes and I was testing the system. THe CPU usage goes between 2 and 70 percent staying around 25% on average, when I check my e-mail. As soon as I click on Google taskbar (without even typing in anything) the CPU usage jumps to 100% and STAYS at 100 %, and computer extremely slow.

Unable to access Web based emails with latest version of Firefox

I have to use Internet exploree to view my emails.
Any way to change this.

BBC Radio iPlayerwill not work with latest version of Firefox.

I have updated all necessary software (Flashplayer, etc.) and am forced to use Internet Explorer to listen to BBC Radio. Earlier versions of Firefox do not have this problem. I am not a computer programer, just a user. I have used Firefox for years and been able to listened to BBC Radio for years. I've read all the advice on various Firefox fora and not found anything useful in solving this problem. It seems to be a problem intrinsic to the latest version of Firefox itself. Will this problem be fixed in the near future? It seems to have been going on for the better part of a year in both the US and UK. If not, why not?
My expertise is in chemistry, not computers. I need a browser that works. I'd like that browser to be Firefox, but I don't have any more time to spend on trying to fix this problem. Using two different browsers is not working for me. Please fix this.

Before I suggest you to revert back to Firefox 28.
Try this
Certain Firefox problems can be solved by performing a ''Clean reinstall''. This means you remove Firefox program files and then reinstall Firefox. Please follow these steps:
'''Note:''' You might want to print these steps or view them in another browser.
#Download the latest Desktop version of Firefox from http://www.mozilla.org and save the setup file to your computer.
#After the download finishes, close all Firefox windows (click Exit from the Firefox or File menu).
#Delete the Firefox installation folder, which is located in one of these locations, by default:
#*'''Windows:'''
#**C:\Program Files\Mozilla Firefox
#**C:\Program Files (x86)\Mozilla Firefox
#*'''Mac:''' Delete Firefox from the Applications folder.
#*'''Linux:''' If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it - see [[Installing Firefox on Linux]]. If you downloaded and installed the binary package from the [http://www.mozilla.org/firefox#desktop Firefox download page], simply remove the folder ''firefox'' in your home directory.
#Now, go ahead and reinstall Firefox:
##Double-click the downloaded installation file and go through the steps of the installation wizard.
##Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.
More information about reinstalling Firefox can be found [https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems?esab=a&s=troubleshooting&r=3&as=s#w_5-reinstall-firefox here].
WARNING: Do not run Firefox's uninstaller or use a third party remover as part of this process, because that could permanently delete your Firefox data, including but not limited to, extensions, cache, cookies, bookmarks, personal settings and saved passwords. These cannot be recovered unless they have been backed up to an external device!
Please report back to see if this helped you!
Thank you.

Cannot play flickr videos on firefox, works on other browsers. using mac 10.8.4 with latest versions of firefox and flash

Firefox is my preferred browser but it drives me nuts that I cannot play flickr videos... have upgraded to latest version of firefox for Mac... have new Imac with 10.8.4... also upgraded to latest version of flash.. nothing I do seems to work... help

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 [[Troubleshooting extensions and themes]] 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.

Why is Hotmail Calendar not working with latest version of Firefox

I was prompted to load the 'latest' version of Firefox this morning, which I duly did. Since then my Hotmail account has worked fine for send and receive but I cannot access my calendar. Screen simply says "loading...." and never actually loads.
I have shut my lap top down fully and rebooted but the situation remains the same.
I have 2 Hotmail accounts and this problem is the same for both. Please could you advise.

iSight is the camera. I expect you mean that Skype will not recognize the camera.
(1) Did you restart Mac and try again?
(2) Did you use Disk Utility to repair permissions before and after installing Skype?
(3) Because Skype is your only problem app, have you checked Skype support such as
https://support.skype.com/en/faq/FA10931/ and
https://support.skype.com/en-us/category/VIDEO/
There are Skype-specific tips there that may help you.
Do NOT add any drivers. All needed iSight driver software is included in your OS X 10.6.8
You can also search Skype's dedicated forum for Mac http://community.skype.com/t5/Mac/bd-p/Mac
(4) Your first download or install may have been faulty. If you have not already done so, try downloading the latest Skype version again and reinstalling? Remember to repair permissions before and after the reinstall.

Cannot print with HP Officejet 6100 with latest version of Firefox

Since I received the latest version of Firefox I cannot print anything that's online. I'm using Windows 7.

Thank you for your help. When I try the "reset firefox printer setting" and type "print" in the search field, I get the settings for the two previous computers and the current one. If I type "print-printer", I get a blank page. Also the menu button disappears. If I click on the setting, "delete" is not one of the options. If I try to"reset all firefox printer setting" and click on "show folder" under application basics, a list of files and folders opens. the prefs.js file is only 23KB (JScript Script File) long and cannot be opened, so I cannot remove any lines that start with "print".

With latest version of Firefox, my printing choices diminished

When I hit print in the file menu, it used to offer me an option of highlighting part of a page and only printing that selection. 
It no longer does that after the most recent upgrade of Firefox. 
How can I get it back? 
The fixes I've been offered on boilerplate pages are useless.

Hi coliandroet
I've edited your post and changed the uppercase you used to lowercase to make it easier for us to read.
In case you have a problem with reading or writing (smaller) lowercase text, you might be interested in the NoSquint extension.
You can use the NoSquint extension to set font size (text/page zoom) and text color on web pages.

Cannot download videos from YOUTUBE since you ugraded Firefox.

Since your recent upgrade to Firefox 5, I am unable to download Videos into RealPlayer through Firefox. I can with I.E. however I absolutely detest I.E.
How can I FIX this problem? I do NOT want to change my Browser...I love FireFox!

It notified me that it was not going to be compatible with Real Video so I skipped the update and somehow it ended up taking place anyway. Can we go back to the days when the Portable Version of Firefox wasn't automatically updatable? Nothing worse than getting a version forced on you that breaks compatibility. Why exactly do I need Firefox 5 anyway? I would much prefer an update that goes - "We have a new version. Go to our site to get it if you think you might want it" rather than one that comes down from one click of the mouse.

Problem with latest version of firefox 15.0.1,whenever i download video from youtube or any other site using idm it shows .webm format instead of flv or mp4.
