Diễn đàn hỗ trợ Firefox

I can't play any youtube videos on my firefox. All my programs are update to date. Also youtube videos are working for my internet explorer but not on my firefox. I have the latest version 3.6.13

I'm on a PC 32 bit home basic vista.

My Firefox often freezes when I'm trying to open a site in one tab or several. The freezing lasts for a couple of seconds but its really frustrating.

The version is the latest stable (3.6.13) I've tried re-installing the browser, but the broblem persists.

I cannot print emails anymore and I have to print other things from web searches with no results. Paper just feeds straight through the printer and print previews are blank. I can print pdfs etc from my documents and did print from internet explorer last night.

I have tried looking through all the setting that it gave me and i can not find when it wont let me open a new tab. All the settings i have are the default settings and before it happened i hadn't even been into the setting so its not like i was messing with them and then it messed up it just happened one time. I do not have any viruses or anything because i use 3 different virus scans and they say my computer its clean. Also my virus scanning programs are up to date i updated them today.

Firefox crashes unexpectedly when loading some pages. It does not crash on specific pages. It will crash unexpectedly on any website.

I have settings set to send reports to Firefox, but I have never received a response or fix. 

I tried fixing the problem using the knowledge base. It did not fix the problem.

Whenever I attempt to print something from Firefox (email, receipt, and so on), printing fails and I get the message "an unknown error occurred while printing." Printing from Internet Explorer works without any problem.

Quite often I come across sites like this

with some articles in them. I always use the 'print preview" before I print. On this one, what I get is: page 1 of 3: a page with several lines of heading - the rest of the page is blank page 2 of 3: the text starts, and gets chopped at the end of the page page 3 of 3: blank

Even an old piece of junk like IE8 works properly! I have other examples of this behavior - it isn't just the print preview, it actually prints like that too! I can never get the whole text. IE8 shows me 8 pages for this particular article.

Under Tools > Options > Tabs, "Warn me when closing multiple tabs" is selected. Also, in about:config, browser.tabs.warnOnClose is set to "true". I always have multiple tabs open. However, sometimes my hand slips or the mouse falls off the table and Firefox closes without any warning.

If I type "NBA" into the address bar, I will get results from yahoo. I don't want yahoo results, I want Google results. This just started happening today. How do I get Google search results to show after typing into the address bar?

Every time I go to Wikia or Wikipedia or even signing in to my AIM mailbox OR even type the code in reCaptcha. I always encounter the strange characters issues instead. I tried to follow all the so called solutions provided but none ever work. I had to rely on Chrome to go to these websites because FF can't. I even hard-reset on my profile.

A much-used feature has disappeared. By clicking a link with the center wheel of the mouse, it would open that link in a new tab. Now it doesn't work any more. Please, how can it be restored?

I can not print from the web with Firefox. I can print emails, pdfs, word documents, Excel -BUT the web page comes out blank. When I use Explorer - I have no such problem. I have uninstalled, restarted and re-installed. I have also reinstalled my printer. Help.

I also use firefox for banking for safety reasons but all my bank home pages also look very distorted. The font has reduced quite drastically. I zoom in a few times to see the fine print but the surrounding font looks much larger. How can this be fixed?

I want to use the QuickTime plugin for Firefox, but version 7.1 is blocked, and version 7.2 doesn't support Windows 2000.

I'm fine with running 7.1; the risk is very small, and I'm willing to accept it. Or does someone have another solution?

My computer crashed and essentially I do not have access to any of my bookmarks. Is there a way to retrieve them? Were they stored anywhere else besides my computer?
