I removed the fx3 content, fixed nested lists, removed the duplicated keyword, removed Linux from Win screenshots, declared screenshots without the Sync panel as fx35 specific. It needs review.

I have a problem with declaring the screenshots without the Sync panel icon showing in the Options window as fx5 fx35 specific and then hiding them from Firefox 4 and above, if you aren't going to add new screenshots. I think it's fine to show the screenshot if it is important to point out what needs to be clicked (the "Show Cookies" button in this case) if the only difference is that the Sync panel icon is missing from the Options window, if the rest of the Privacy panel information is the same.

Using similar logic, wouldn't you have to declare any screenshot that doesn't show the Tracking option in the Settings for privacy, browsing history and do-not-track (as shown here for Windows, fx5) as either Firefox 4 only using {for =fx4} (with Sync panel icon) or {for fx35} (no Sync panel)?

See /forums/knowledge-base-articles/707035 for a discussion about the screenshot policy according to Firefox versions.

In a new revision, I added the Fx5 Show Cookies screenshot for Windows, but not the Firefox 4 one as it is no longer maintained.

would it also be possible to make deleting all cookies more clear for fx5 on windows Vista, 7? I don't think most users can get to or know how to get to the tools menu.

In a new revision, I fixed the fx4 menu path for the "Delete all cookies" section. It needs review.

Followup on whether or not to show [[Image:Deleting Cookies Fx 5 - Win1]] for Firefox 4:

Generally, I think showing this image to Firefox 4 users should not be a problem because the article has nothing to do with the tracking feature and showing this image would also be fine because the article has nothing to do with the Sync panel or it's relationship to the Privacy panel.


In any case, I have no problem with not showing the Firefox 5 screenshot for Firefox 4, which is no longer maintained.

I approved the last revision.

I went ahead and changed it so that the "deleting cookies" image would show for fx4 and marked it as ready for localization.

  • Either it is the click on orange button > History > Clear recent history ...
  • or (in the Firefox menu) Tools > Clear recent history ...

Means, my change is probably incorrect. On the other hand, you need to read carefully to see the context.

The last approved edit was incorrect. The pending revision by underpass has the correct instructions:

click on the {button Firefox} button, go over to the {menu History} menu (click on the {menu Tools} menu in Windows XP) and select {menu Clear Recent History...}

Unless I'm missing something, I think the revision by underpass should be approved and marked ready to localize.

+ for underpass and Alice.

PS: if the edit was indeed approved (by myself evidently), then it was my oversight and my two thumbs. I'll be more careful in the future.

I approved the revision by underpass and marked it ready to localize.

Why to delete all cookies via Clear recent history... dialog, if there is a Remove All Cookies button in Cookies window.

Why to delete all cookies via Clear recent history... dialog, if there is a Remove All Cookies button in Cookies window.

Good question.

Could I make a new revision?

I can't think of any reason why we should use Clear Recent History to clear all cookies, unless someone at one time thought it was easier than going through the Privacy panel?

You could go ahead and made a revision ... and maybe include both methods of clearing all cookies? For example,

Delete all cookies

To delete all cookies stored on your computer, either open the Cookies window as explained above and use the {button Remove All Cookies} button, or else do the following:

I think it's better to keep the old instructions and just edit the beginning of the "Delete all cookies" section as follows:


Delete all cookies

To delete all cookies stored on your computer, either open the Cookies window as explained above and use the {button Remove All Cookies} button, or else do the following:


I made a new revision that's pending review to do the above.

I found a mistake in the article: you don't need to set Firefox will: to Use custom settings for history, because there is also a link to Cookies window when Firefox will: is set to Remember history.

It may really be a bit easier to delete cookies through Clear recent history, but we can significantly shorten and clean up the article if we use the same instructions to remove all or only particular cookies. Why do you think that it's better to keep the old instructions?

Yes, when "Firefox will:" is set to "Remember history" there's a link labeled "remove individual cookies" (shown here) that opens the Cookies window where both individual cookies and all cookies can be deleted. You could use either option but I think it might be confusing to tell someone to click a link labeled "remove individual cookies" when they want to delete all cookies. I would leave the instructions as is.

If it's easier to use Clear Recent History then we should include those instructions for anyone who simply wants to remove all cookies. Others may want to shorten the article and leave it out but in your revision, you make the user read through all the steps to remove individual cookies, even though they might want to simply remove all cookies. I think you should have a separate "Delete all cookies" section for those people, and then tell them to follow the previous steps but to stop short of of searching for individual cookies and use the "Remove All Cookies" button, like I have it in my revision.

Hopefully Joni will see this discussion and review the pending revisions.

Upwinxp raises a good point, but I'm leaning towards Alice's suggestion that we should give users the option to delete cookies via "Clear recent history". "Remove individual cookies" seems a bit counter-intuitive to someone who just wants to delete everything.

I'll review the revisions now.

Thanks! Joni
