Diễn đàn hỗ trợ Firefox

OK. I found an answer in a thread here but it is already closed. I have an additional question. The moderator said there: Quoting: Depending on what you want to do there are a couple of options.

If you want to replace the bookmarks on the other computer with the bookmarks from your desktop, use the method in this link to backup the bookmarks to a file and then restore them on the other computer - https://support.mozilla.com/kb/Backing+up+and+restoring+bookmarks

If you want to add the bookmarks from the desktop to those that already exist on the other computer, you need to export them to an HTML file, and import that file on the other computer. See these links for details:

   https://support.mozilla.com/kb/Exporting+bookmarks+to+an+HTML+file
   https://support.mozilla.com/kb/Importing+Bookmarks+from+an+HTML+File 

I want to do the second one - "add the bookmarks from the desktop to those that already exist on the other computer" The problem is that my Firefox is version 4.0. I read somewhere in the bookmarks topics that I should have done nothing before upgrading to version higher than 12. The thing is my computer is 8 years old and I have only 512 MB RAM. There is no way to upgrade more that v.4.0. My computer can not handle it.

Any suggestions? Can I export and import with v.4.0 safely?

I've had Firefox 4 since the release date, but today it's been acting up - it's not loading certain webpages properly, removing all the formatting and just putting all the text/links/etc in a list along the left hand side of the window. It's also not showing some pictures at all any more, although they're all hosted on Photobucket. This is literally ther first time there's been a problem with it since updating, and I've not changed any settings on it at all, so I have no clue why it's suddenly broken. Is anyone else getting this?

Firefox tells me that a site has an invalid security certificate, which I know. It asks if I want to Add an Exception and I click to add one. It pops up the Add Security Exception window and that window tells me that this site has a valid certificate and there is no need to add an exception; but I DO need to add an exception and it won't do it for me. Why? I am working in a secure test lab and use Firefox to login to our systems under test. Each time we change or add hardware we must add exceptions to login to a system. I have done this for years with Firefox but now Firefox 4 seems confused. We now need to use EI, which I would rather not.

After I click View/Full Screen on the Firefox menu bar, I lose the main FF Menu bar. When I hit the esc key, the screen remains locked in full screen view mode. Then I have to reboot my computer to get back to the default FF menu and display mode.

Why doesn't the esc key work the way it works when I'm viewing videos in full screen mode?

re my browser - I do not know which version it is. Some websites tell me they are not supported by what I have, e.g. one requires F'fox version 9 - question: how do I know what I have and how to upgrade?

When using my eprint function (e-mailing attachments to my printer through gmail), I have to send the attachment without subject or text in body to prevent it printing extra pages. Gmail automatically asks me "Send message without text in body?" and "Send message without a subject?" which was getting annoying. SO, I clicked the checkbox marked "Prevent this site from creating any more dialogs," hoping that would stop the pop-ups.

Now, the pop-ups don't appear, but gmail simply doesn't send the message, so I get stuck unless I enter a subject and body text (which is a pain and wastes paper by printing an extra page). I can't figure out how to 'undo' what I did in either Firefox or Gmail. I'm using version 4.0.1.

Help???

When I point Firefox 4.0.1 to the Plugin Check page

<http://www.mozilla.com/en-US/plugincheck/>

It flags the following plugin as outdated:

Shockwave for Director Adobe Shockwave for Director Netscape plug-in, version 11.5.9

However, I have the latest version of Shockwave installed (11.5.9.620) installed. Reinstalling the plugin does not change how the Mozilla Firefox Plugin Check page sees that plugin.

An error occurred during a connection to rserving.com.

Here's an example of what happens when I cancel the username and password request: ERROR: Cache Access Denied Sorry, you are not currently allowed to request:

from this cache because your username and password are incorrect or your user group does not have permission to web browse. Please check your username and password. They are case sensitive so make sure Caps Lock is not on. This happens 100% of the time.
