After the transition to Windows 7, there was a problem with Firefox. To work with the text to the award by the cursor of the large fragment of page it is necessary to change all the time down, 'against the judgment", but the page automatically does not ascend to the top as it was earlier, and like that occurs in other browsers. It is necessary to press the other key "down" which is him very troublesome. Resettlement on an earlier version (8.0) earlier irreproachably working, gave nothing. I ask you to help
You must activate the module bar (Firefox > Options or view > toolbars;) CTRL + /) or find bar to make Firefox scroll the page while selecting the text (Ctrl + F).

just has got rid of the virus and responsible for all the disks but given the wifi does not work
Hello
Check with the system manufacturer or the actual WiFi device manufacturer and ask in their forums (if any)
for problems known.Actually, try updating your driver:
Control Panel - network - write down of the brand and the model of the Wifi - double click top - tab of the driver - write
version - click the driver update (cannot do something that MS is far behind the pilots of certification). Then
Right click on the Wifi device and UNINSTALL - Reboot - it will refresh the driver stack.Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.

You can download several at once however restart after the installation of each of them.
After watching the system manufacturer, you can check the manufacturer of the device an even newer version. (The
manufacturer of system become your backup policies).Repeat for network (NIC) card and is a good time to get the other updated drivers as Vista like
updated drivers.I would also turn off auto update for the drivers. If the updates Windows suggests a just HIDE as they
are almost always old, and you can search drivers manually as needed.How to disable automatic driver Installation in Windows Vista - drivers

I tried to hear an appeal of a Web conference. Received a message, necessary plug windows media. Check my plug ins, no windows media. Reading about firefox support tutorial. Clicked on download. Had a window that requires repair or change. Tried to fix it and then change. Need better guidance on how to finish download. Download the message passed, but after firefox closing and re-opening, no still no plug-in for windows media in the list of plug-ins. Go to site and could not hear Conference.
Reading support forum. Message while using about: config. Tried, typed in on: config in Start menu, but do not see anything that looked like I could change for real like message said.
solved by opening internet explore and go to the website and listen to the conference call on windows media player. There was a message saying: If you want to enable media player click here. Not so heard Conference.
Tried using chrome. You have to listen to the Conference yesterday. Today, he had the same message you need to plug in when I tried to follow the instructions in connect, it was just as confusing and useless like firefox. Most is that I tried to make any statement in the suggestions forum for firefox and can not get the windown media connect to appear in my list of plug-ins and can not hear calls for conference on firefox.
Chrome said that they worked on connect available to the chrome store.
I agree with the comments that I was able to go to web sites and to hear the calls before firefox did an update that removed my windows media plug. The fix simple download, two from windows, does not, apparently because firefox cannot find the fix. This isn't for lack of user, and it seems that windows attempted to provide a fix, and firefox does not recognize.
Bottom line, it is easier to use another browser, that trying to get windows connect multimedia player installed on firefox. What is a browser, if you can not hear an appeal on the Web site the browser will take you to? Please make it easy install windows media branch on firefox. Thank you..If you get the screen to change/repair, it means that the Setup program has detected that you have already installed the plugin.
Do you not see the file here:
C:\Program Files (x86)\Mozilla Firefox\Plugins
Its file name is: np - mswmp.dll
If the file is missing, I suggest to delete and then reinstall the plugin.
Edit: By removing and then reinstalling I mean using the delete button under the modification and repair buttons in the Setup program, and then run Setup to reinstall.

On another PC I want to save my favorites, but my browser Firefox does not work how can I make the backup, before I reinstall Firefox.
Firefox cannot renew its tabs and now won't run and let me do a backupThis may be considered to be solve my problem.
I decided to uninstall the rogue program Firefox download and reinstall the same version (No. 8). I used Windows XP Add Remove programs who asked if I wanted to save the settings of Firefox until I uninstalled Firefox. I said yes and operated with the uninstall. I couldn't find a Firefox 8 so I went for the 12 version and installed on the laptop. This version 12 now works with all the passwords one favorite of the uninstalled 8.
Thank you for all your help and advice. -
Wolf 3D and SoD does not work on Windows7 32 bit but it does in Windows XP?
I have already downloaded versions freeware and shareware of best games in existence! (Wolf3D and Spear of Destiny, nested DOS, original version) In Windows XP, it worked well, all I get under Windows 7 Home Premium 32 bit is a black window feared, blinking icon and the opportunity to do nothing but close the window!
I tried to run the application in compatibility mode with previous versions of Windows (including Windows 95!) But Windows 7 is so automatic that I can't change any settings.
Not much of a computer geek, but Microsoft seem to think that something before 2007 is not worth worrying about
Can anyone help?

Hey guys, so I have an ASUS X502C and last night, it has become very slow, that I tried to close all pages open and it started making a very loud noise. I couldn't even turn off, so I closed the lid and went to sleep. When I woke up it was still on the same screen until I tried to close it and turn it off. He went to a black screen with the back light on. My model is an integrated and I was afraid to take it apart and * it upward. I tried all the f keys, but only F2 works. It does not display my HD, and it does not start. What should do?
