Diễn đàn hỗ trợ Firefox

Where does firefox store the bookmarks, saved passwords, optional settings, etc.? Can these files be moved to a directory of my choice so I can easily back them up?

Thank you, Paul

I do web development. I was working on a site with a self-signed certificate and therefore had to create an exception in Firefox to access the site using https. Due to unrelated problems on the server, I deleted the account and then recreated it. I also had to create a new self-signed certificate. Now Firefox returns the message Error code: sec_error_reused_issuer_and_serial. I deleted the original exception from Firefox but it still returns the error. I tried to explicitly create a new exception but that returned the error, too. Note I do not have this problem with other computers on the same network and the problem does occur if I move the offending computer to another network. i.e., the problem is associated with the computer, not the network or router.

I go to YouTube to play a video and it does not work, there is just a black space where the video would be, but Internet Explore will play the video, i really like FireFox, but i need for this to work and be dependable if not im gonna have to switch back to IE

i also tried this on another computer and had the same problem with Firefox

The lines got narrower and the print size ( font size) is so small I can hardly read it, and the categories on the left side of the incoming email page are also too small to read. In addition, I can't make the LARGE print the default for outgoing emails and would like to do that.

So I tried to watch a video on YouTube, yet Firefox just shows a black box. Neither the video nor the audio will play. It doesn't crash my browser or bring up any errors, which leads me to believe that it is not a Flash Player problem.

I opened Google Chrome and tried, and it plays YouTube videos with no problems.

I restarted my computer, yet it still does not work.

Any assistance is very much so appreciated.

Unable to load Youtube videos. Am able to view them with IE on same computer. Have uninstalled and reinstalled latest Flash. Do not get sound. Only black screen where video is supposed to show. Can see Youtube webpage and listings.

I am reading a pdf online and I want to follow an embedded link, but I get a security block telling me "In safe reading mode, this document does not allow connection to: http://www.sandiego.gov.development-services/ industr/pdf/infobulletin/ib500.pdf

If you want to enable this function, please check the Trust Manager preferences to change out of safe reading mode."

I looked through every menu item in the tool bar and couldn't find the Trust Manager.

I watch videos on Youtube, and shortly after updating Firefox, I have noticed that the sound for the video is fine, but the image is a blank screen. I have looked at every control and I can find no reason why I get sound but no picture when playing the video.

When I want to send an email, even now, just about all words have a squiggly red underline. This just started a few weeks ago. Spell check is also affected. The red lines do not pass through to recipient. Tried re-loading Firefox. I am using Yahoo mail and don't have this problem with IE

Got notice of upgrade. Downloaded 3.6.15 and installed. On your page describing new features, you prominently mention "Location-aware browsing," as well as the fact that I can turn this spyware off, but after looking through all the "Tools" area, I cannot find a way to turn it off. I am absolutely disgusted that Mozilla has been allowing people to spy on me all these many years I have been using your browsers clear back to Netscape. How can you get away with this without asking my permission? NOW TELL ME HOW TO TURN OFF THIS INSIDIOUS PIECE OF *!

I've tried resetting things, I told firefox to forget all my stuff when I deleted it and reinstalled it and this thing still isn't gone. I'm not a technical person and I don't really understand any of it.

When I read message boards (Reddit), the posts that I have already clicked on turn purple. Later I can come back and see at a glance which posts I have read and which ones are new to me.

I am used to using Chrome for this, but lately I have been experimenting with Firefox. When I went back to the message boards using Chrome I noticed that the previously clicked on posts were not purple (because I had viewed them in Firefox).

No worries! In Chrome I can click on the wrench, options, personal stuff, import data from another browser. I just choose Firefox from the drop down menu and instantly my click-on history is caught up.

Firefox on the other hand does not seem to have this feature. When I click on "file" in the menu and import it only gives me the option to import from Internet Explorer.

To be clear - I do not care about importing/exporting bookmarks. I already have the same bookmarks on Chrome and Firefox. I do look at several message boards and it is a big inconvenience for me to have to click on links that I have already seen, just to turn them purple, so I will be able to more easily recognize the links that I haven't clicked on yet.

Even though I would like to start using Firefox more, I find that I am "forced" to return to Chrome because it is so much easier to read message boards that remember what I have clicked on.
