Do you want to move cookies between two instances of Firefox or among different browsers?

• Import from other browser on the same machine into Firefox: Import Bookmarks and other data from Microsoft Edge, Import bookmarks and other data from Google Chrome (yes, it says bookmarks, but also covers cookies)

• Export cookies from Firefox, import into Firefox from a cookies.txt file: These features do not exist in Firefox. You could consider using an add-on. I haven't used any of these myself.

Cookies Manager+ :: Add-ons for Firefox (backup/restore feature)

Cookie Exporter :: Add-ons for Firefox
Cookie Importer :: Add-ons for Firefox

Cookies Export/import :: Add-ons for Firefox

There are other things that need your attention.

Your system details list shows two Flash plugins and one is a very old Flash 9.0 r45 version that you need to remove.

• Shockwave Flash 9.0 r45

You can set the plugin.expose_full_path pref to true on the about:config page to see the full path of plugins on the about:plugins page.

• http://kb.mozillazine.org/Issues_related_to_plugins#Identifying_installed_plugins
• http://kb.mozillazine.org/about:plugins
• http://kb.mozillazine.org/about:config

It is best not to leave that pref set to true as it exposes that full path to web servers, so reset that pref to false after you are done with the about:plugins page.

Thanks. I. think the best for me is to choose a browser that was made for people who has many other things to do than fight with their pc's most of the time. I simply cannot understand that such a simple task must be so simple to perform. Kind regards

Hi ngr6, I think exporting and importing cookies is not a frequently used browser function, and that's why add-ons were developed to add that feature.

Whatever browser you end up choosing for daily use, it is a good idea to remove the old insecure Flash DLL mentioned by cor-el.

Thanks, but I don't understand a word of what cor-el is saying, and have no idea whatsoever about what "the plugin.expose_full_path" means. Perhaps you are right, that "exporting and importing cookies is not a frequently used browser function". I have wanted to use it app. twice every year.

What cor-el is saying is based on your More system details information (link to the right of your post). The current Flash player is listed at the top, and the old Flash player is listed at the bottom. That's the one you should try to remove. Unfortunately, you can't remove it using Firefox; you need to use an Adobe uninstaller or locate it on disk and delete it manually.

In order to locate the old plugin on disk, you could search around on your hard drive, or you could temporarily have Firefox show the full path to the file. In order to get that full path, you make a quick change in Firefox's about:config preferences editor. Here are the steps, step by step:

(A) Temporarily enable the display of the full paths. Because websites can read this, too, you should turn it off as soon as you are through troubleshooting.

(i) In a new tab, type or paste about:config in the address bar and press Enter. Click the button promising to be careful.

(ii) In the filter box, type or paste expose and pause while the list is filtered

(iii) Double-click plugin.expose_full_path to toggle the preference to true. Leave this tab open.

(B) Inspect the path

(iv) In another tab, type or paste about:plugins in the address bar and press Enter.

On this page, you should be able to see the full path on disk to both of your Shockwave Flash plugins. Does it show?

(C) Delete old file

Windows might let you delete it immediately, or might complain that it is in use. You might keep a Windows Explorer window open to the relevant folder in that case.

You can close the about:plugins tab.

(D) Turn off full paths

(v) Back in your about:config tab, double-click plugin.expose_full_path to toggle the preference back to false. You're done with about:config.
