Diễn đàn hỗ trợ Firefox

my Facebook page has shrunk, it is not fullscreen and you cant read it. it's like the whole page fits half of my screen and is so tiny how to I change it back to full view?

So about 5 days ago this problem started.

I've tried everything, uninstalling, reinstalling, installing older versions of Firefox, everything in the help file about this, going into about:config to set scanning to false, uninstalling my virus program (avast), etc.

They only thing I didn't try is restore points because they didn't go back far enough.

What could this possibly be? The moment the download finished it's absolutely gone.

I am a web developer. I tried HSTS (HTTP Strict Transport Security) in my developing website.

Now I want to cancel (forget) the HSTS setting for this site, but I cannot. Cannot I access my developing website with HTTP anymore?

How do I get ride of the dreadful CONDUIT SEARCH which has colonised my Firefox search like computer Herpes? I have tried a few of the replies but nothing has helped - it appears nowhere on any program list and even the following didn't do the trick :-

Owner AnonymousUser 1 year ago Several tried to but no one seemed to understand the real problem. I COULD, because it was mine too. So it follows the only ultimate solution:

1. Open Firefox 2. On the address bar, type – about:config in the URL. Press Enter.
3. You will be warned about Warranty. Click on “I’ll be careful…” 

4. On the Filter dialog box type – search.conduit 5. It will display all related entries. Right-click on Preferences Name and Reset. It worked for me, after trying a dozen of "fake" solutions. ;)

Other than serious chainsaw work, any ideas?

I was doing nothing in particular when I realized everything was text only with no graphics. When I opened the same page in Safari - happened to be gmail - the page appeared as it should with graphics. Text only is appearing on all sites opened in FF

I reinstalled firefox recently and now every time I click a link it opens in a new tab instead of in the same tab. I would rather change it so it opens in a new tab only if I tell it to but for some reason that option is no longer in the options tab. How do I disable this function in the newer firefox?

Not only does firefox not show images, but also won't play audio online. Also my hotmail seems messed up, with text over text etc. It doesn't even show images on the firefox pages

How do I turn off this blocking message? "firefox prevented this page from automatically redirecting to another page " It used to be annoying, but now it has completely blocked me from logging in to a website.

On YouTube and other Flash based video sites, Flash drops a huge number of frames, making playback very choppy even with the smallest resolution (360, 480). This doesn't happen with IE, not even while using the highest resolution (720, 1080) available. I know my computer is more than powerful enough to play back full HD, even without hardware acceleration. Is this Firefox's fault or Flashes and is there anything I can do about it?

i know to solve this problem by going about:config and to correct it,but i want to know whether is there any other way to block this dialog box. How all the user of my application will follow that ?

When updating windows 7 I get the following response: Windows could not search for updates An error occurred while checking for updates for your computer error(s) found code 80072ee2 windows encountered an unknown error

click here to     get help with this error

When I do this - get help - the "fix" doesn't fix it and I eventually come back to this same window

The last time I was able to update windows 7 was in December 2011.

This same problem has happened before but the "fix" fixed it some time.

I get the same error when I open internet explorer.

I am trying to print to a Zebra GK420d Label printer and firefox will not remember my paper size after one label is printed. Ideas on how to force a paper size and have it remember it?

I am on windows 7 and have changed my paper size for Printer Preference and Printer Properties and it will print correctly in notepad.

I had a virus on my computer so I had to reimage it, wiping out everything and starting new. I lost all my bookmarks (thankfully, I wrote them down before reimaging). Is there a way to email myself a file which contains my bookmarks, which I can then use to reload my bookmarks?

This sites (http://video.pbs.org/) drop downs "Programs" and "Topics" don't work when clicked. This page (http://www.modcloth.com/shop/dresses/ain-t-over-until-it-s-clover-dress) when clicking on the thumbnails of the green dress, the larger view pic does NOT change.

I've seen a few posts about the AVG 2012 Search, but none match what I'm looking for.

My homepage is set to google.ca, and my quick search toolbar is set to google as well with all other search engines removed.

I didn't have this problem before until yesterday when I formatted my computer and re-installed everything.

If I type in the address bar terms to search, hit enter, it use to come up with a Google results page. Now when I type up there, hit enter I get an AVG secure search page powered by Google, and the address bar icon changes from a Google logo to AVG.

Only if I type in the address bar. When I open a new tab the cursor always defaults into the address window not the google search page so, always forget to click into the google page and type. In any case, if I search with the google search bar or on the google webpage it's fine, it's just if I type in the address bar and hit enter that I get this http://isearch.avg.com page.

Anyway to switch it back to google?
