When I open a new tab, I can see the thumbnail of pages that I have visited or pages that I save in mht. I would like that this thumbnails do not be saved in any way.

I have using firefox 22 and I try many solutions.

The first one is in the about:config, change the value of the parameter browser.newtab.url to about:blank. This HIDDE the thumbnails, but if I save a new webpage in mht, set this parameter to the default value (about:newtab), exit firefox and enter again, if I open a new tab I can see the thumbnail of the page that I have saved when the parameters had the value about:blank.

Other solution is config the parameter browser.pagethumbnails.capturing_disabled, but this parameter does not exist in the version 22 of firefox.

I also try to set the parameters app.update.lastUpdateTime.browser-cleanup-thumbnails to 0 and browser.pagethumbnails.storage_version to 0, but this parameters is restore to default values, so at least the thumbnails is created.

So I would like to know how can avoid the creation of the thumbnails. the first solution is a bad solution, because if I save webpages, the thumbnails are created, but I can't deleted manually because the newtab is hidden, and if someone wants to know what I save, this person only need to restore the default value of the parameter. So my privacy is not secure.


Thanks.

At least I find the solution. I follow this steps:

1.- In about:config, I create a new parameter, browser.pagethumbnails.capturing_disabled, it is a boolean and has a value of true.

2.- HOw I have in options-->privacy the selection of always use privacy navigation, I can't clear the history as waka suggest, so in options-->privacy I uncheck the permanent privacy navigation and then I clean all the history as waka suggest.

3.- In options-->privacy I check again the option of using always private navigation.

I don´t have more thumbails when I save webpages.


Thanks.

Hello,

Many site issues can be caused by corrupt cookies or cache. In order to try to fix these problems, the first step is to clear both cookies and the cache. Note: This will temporarily log you out of all sites you're logged in to. To clear cache and cookies do the following:

  1. Go to Firefox > History > Clear recent history or (if no Firefox button is shown) go to Tools > Clear recent history.
  2. Under "Time range to clear", select "Everything".
  3. Now, click the arrow next to Details to toggle the Details list active.
  4. From the details list, check Cache and Cookies and uncheck everything else.
  5. Now click the Clear now button.

Further information can be found in the Clear your cache, history and other personal information in Firefox article.

Did this fix your problems? Please report back to us!

Thank you.

Well, I use don't remember history, I have configurated to use privacy navigation by default, so I don't have enabled the option to clean recent history.
