Ondersteuningsforum voor Firefox

I am receiving a "couldn't load XPCOM" error. I know that I can reinstall Firefox but when I went to do that it erased all of my bookmarks so I did a system restore. How do I save my bookmarks?

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:

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 had to replace my motherboard and install a new operating system on a new hard drive. Windows 7.

The old hard drive has windows 7 OEM and would not boot with the new MB.

I need to recover the bookmarks from the old HD which is connected to the new MB.

I can access the folders. I just can't find the bookmarks. 

I need them to be complete because I used hints in the bookmarks to be able to sign in to some sights that I can't remember.

Help Please!

I have Firefox 23.0.1.

I am trying to import Firefox bookmarks from a json file on another disc, and merge these with my existing bookmarks.

I only have options to import an html file. I can also use restore to bring in the file, but this will overwrite my current bookmarks, and I want to merge the two.

I would like two or more tabs to open when I open my homepage. If I try to drag the open tab to the homepage button it just replaces what is ther with the new one, instead of adding it.

I took the old drive out of the laptop and put it in a USB case so I now have my entire OLD hard drive as drive E ...but no applications will actually run of course. So...I want to find my OLD profile on drive E (particularly bookmarks) and copy and move it to my NEW firefox installation on drive C. Both computers were/are running Win7 64 bit if that helps. Thanks much in advance for any help.

I did sync two computers, both windows 7, and then I started deleting bookmarks on my work computer, and after that I realized that they are deleted on my home computer as well. I understand now that is normal, and i need to disconnect sync, but I need to restore my deleted bookmarks on the home computer, otherwise my wife will be really mad -))

Before installing windows 10 I forgot to save a list of the bookmarks I had on Firefox. The computer however saved a copy of all important program files in a folder called Windows.old on my C: disk. Is there any chance to retrieve the bookmarks from that folder? I tried to look at the files saved therein, but unfortunately I could not recognize anything useful. Disclaimer: I am definitely not very knowledgeable in IT! ;)

I lost my bookmarks and when I try to restore them I can see the backup files in the restore window but when I try to restore my bookmarks I get the message "Unable to process the backup file." Can you assist? Thanks

There must be a place on my Mac (Sierra version 10.12.5) that Firefox stores browsing history. All of my browsing history was accidentally deleted after my computer was backed up to Time Machine, and I want to use Time Machine to restore the browsing history. But I don't know where the browsing history folder is, and neither did Apple support.

I am having trouble backing up my Firefox bookmarks to dvd. I've been backing up the (XP) FAVORITES folder but I just noticed that the bookmarks in this folder are not my present Firefox bookmarks that are displayed on the Firefox Bookmarks "drop-down." Where are the bookmarks located to see them and burn them to dvd using Ulead Burn Now? I followed the path C:>docs and settings>user name>application data>Mozilla but I couldn't find any bookmarks inside any of the folders within the Mozilla folder. Shouldn't I be able to see these bookmarks in some folder? Thanks for your time and consideration. A.C.

I have already googled the problem & have tried all of the suggested fixes. When I click on the "Show your bookmarks" icon in the upper right, I can click on "Bookmarks Toolbar" and I can see the bookmarks in a list, but they are no longer on a bar near the top of my screen and the "View Bookmarks Toolbar" is already checked. Also, I have already opened the menu, hit customize, & then Show/Hide Toolbars, & the "Bookmarks Toolbar" is checked.

What is prohibiting my bookmarks toolbar from showing?

I used to have my bookmark button (the one where, when clicked, drops all my bookmarks). this button being there allowed me to just drag a tab into it so bookmark it as well as drag the tab into any folders within the bookmarks to simply put a mark there. but the recent update erased this from my bookmark toolbar. i had it on the left most position but it's no longer there and i can't drag any tabs into it anymore as i have to go into the firefox button for bookmarks. how do i bring this back? i unclicked the auto update due to this issue. please help.

All of a sudden (and around the last update, if memory serves, but I'm not entirely sure it exactly coincides with that) my bookmarks toolbar no longer shows any bookmarks. Instead there is a "Bookmarks" button (icon: white star on gray rectangle background) on the left hand side of the bookmarks toolbar. When I click that button, a menu opens in which all my bookmarks are present as usual, including a "Bookmarks Toolbar" folder with the usual bookmarks still in it. In other words, the organization of my bookmarks is unchanged and they're all still there, but the bookmarks toolbar no longer shows the bookmarks in the "Bookmarks Toolbar" folder in my bookmarks menu.

Trying to drag bookmarks back onto the bookmarks folder doesn't work either.

Suggestions, anyone?
