See /forums/knowledge-base-articles/705817 for related discussion about this article.

There are two revisions in pending review, one that adds some missing items, one that is very simplified, with no agreement on which one to choose.

I approved the revision by Michael Verdi before his "greatly simplified" version which is still pending review along with your edit to that revision.

Is there a consensus on whether or not this article should have been simplified? https://support.mozilla.com/en-US/kb/Page%20Info%20window/review/14566

Not much point in reviewing it, if everyone disagrees. :-/

I've edited the title of this thread to "[Approved] Add missing items". Chris Ilias started a new thread on the "greatly simplified" revision that is still pending.

I disagreed with the over-simplified version (see the related discussion thread) so I approved the previous version and left the latest revision pending.

Actually I'm pretty sure we should archive this. It's an advanced feature - similar to the web console or scratchpad. Eventually this feature may go away to be replaced by the new about:permissions (that's just an idea currently - not in the works at this time).

If you're planning on archiving this article (...because it's too technical for this KB?) I would leave it as-is instead of over-simplifying it and then archiving it. (I edited the thread title to add "[Update needed or Archive?]")

For the record, here's the discussion thread in the KB articles forum on a new article being drafted for the about:permissions page:

{Needs Draft} How do I manage website preferences and permissions?

Verdi said

It's an advanced feature - similar to the web console or scratchpad.

I disagree, it's not for developers but for users who want to control the way a website interacts with their computer. They can block cookies only for intrusive websites, or on the contrary, allow cookies only for webmails to get always logged in, for instance.

In addition, it is linked from How do I tell if my connection to a website is secure? which is important.

Eventually this feature may go away to be replaced by the new about:permissions

As the previous change was a small update, I'd say: "Don't simplify it and archive it or merge it with another article when the about:permissions page will be integrated in the UI."

I fixed a typo in the currently approved version (it's address changed to its address) and approved it as a minor revision. The June 7, 2011 revision by Verdi to greatly simplify this article (as well as scoobidiver's minor edit to that revision) is no longer pending review.

I changed the thread title to [Rejected] since there is no longer a pending revision to greatly simplify this article and no consensus for a need to do so.

Whether or not to archive it is another matter but since scoobidiver is against archiving it (and I am, too) I think that the current version is ready to be localized.

The title of this article was changed from "Page Info window" to "View techncial details about the page you are on" ... which has a typo.

(My vote would be to simply name the article title back to "Page Info window" since it describes the name of the window itself.)

I also posted about this on the Knowledge Base articles forum, here:

Yes that's true it should be technical

Yes It is better to put a relevant title to your articles.

So, since Michael Verdi has not responded I'll rename this article to:
Page Info window - View technical details about the page you are on

I renamed the article, which also changed the URL of this discussion thread.

Need to add Show Notifications as a new permission for Firefox 22.

I was looking through the Firefox 22 release notes to answer a support question related to a website's new mail notification and it listed New Web Notifications API implemented.

I then found Bug 782211 - Implement notification API spec (fixed in mozilla22) which mentions "Permissions Management" in comment 18. Here's a screenshot of what it looks like for bugzilla.mozilla.org:

Fx22Permissions

I also found this softpedia article which says,


Sites can now display desktop notifications, useful for things like social networks, webmail clients and so on and so forth. Users must allow sites to display the notifications, on a site-by-site basis ...


I checked the Firefox 22 Research thread and it isn't mentioned.

I hadn't noticed scoobidiver's pending July 12, 2013 revision which added this (among other changes):

Show Notifications
Specifies whether the listed domain is allowed to show notifications.

I approved it as ready to localize.

Hello, now the article says

Encoding: Displays what character encoding the page uses. This can be changed from the Web developer menu

but in Firefox 23 the Encoding menu entry is still in the View menu.

In both Firefox 22 and Firefox 23 Beta, on Windows 7 with the Firefox button, "Character Encoding" is under the Firefox "Web Developer" menu. When I switch to the "View" menu (using the alt button) then it's under the View menu (View -> Character Encoding).

So, this article will need updating to make it {for win7, win8}{menu Web Developer}{/for} {for winxp, mac, linux} {menu View}{/for} menu.

You already have another revision pending so do you want to add that, or should I? which I approved. I made a new revision to the Page title section under Encoding, to add the above (needs review!)

underpass

Thanks Alice, didn't thought it could change according to the presence of the Firefox button :)

I approved my last edit and marked it ready to localize.

I don't know when this changed but it came up on the support forum: /questions/977719#answer-506950
Posted 11-30-2013 by TheOldFox

See if this accomplishes what you want:
  1. Load the site
  2. Click the site identity icon at the left end of the URL/Location bar (globe, lock, etc.)
  3. On the drop down, click "More Information"
  4. On the "Page Information" display, click the "Permissions" tab
  5. Under the "Activate Plugins" section, on the "Adobe Flash" line, click "Allow"
  6. See - https://support.mozilla.org/en-US/kb/page-info-window-view-technical-details-about-page (NOTE: the image for "Permissions" on this page has not been updated to show the "Activate Plugins" section and I do not recall in which version that section was added to the Permissions tab, but it is in Firefox 25)

I uploaded this screenshot:

P.S. I found Bug 821892 - click-to-play: "Page Info" -> Permissions needs to be aware of plugin permission differentiation
.... but that bug was fixed in Firefox 21 (20?)

I made a revision based on the above screenshot. I only updated the article for Firefox 25 since I wasn't sure when these changes occurred.

P.S.. If anyone wants to check this for Firefox 24 (for example, if they have Firefox 24 ESR installed) please do, and update the article to change {for fx25} to {for fx24} if necessary.

Alice, it looks a good article, and I have checked Fx17 & fx24 they have the old type options.

However have you actually gone through all of the options on the permissions page and checked them out for functionality ? Do they all actually always work as expected, intended, and described ?

I seem to find problems & even commented in a bug, although probably not the correct one.

  • #c17 Bug 416557 - Remove "Block images from www.site.com" from Page Info
    • maybe this was the appropriate one to look at Bug 821892 - click-to-play: "Page Info" -> Permissions needs to be aware of plugin permission differentiation

For example If I set this current page to block images and then reload it does not block images. This is in Fx25 but working profile. I will try in a clean profile safe mode and Nightly and append result.

Update: Yes same results.
It was slow enough to see the images disappear and reload again. That was trying on a recent Mozilla Nightly 28.0a1 (2013-11-25) in safe mode and a clean profile created immediately before the test.

Then went back to an esr 10 that has the old style. The page info on that also did not block the images loading. BUT that has the js options under Edit -> preferences -> |Content| -> load images automatically [] unticking that does prevent the images loading. (Mozilla Firefox but Linux OS so odd menu options)

It would seem there is a longstanding problem with this page info window and its use.

Maybe we should document it as not working !! or am I missing something obvious.

On Permissions > Load Images:
I agree that the Permissions option, "Load Images" isn't functioning (how long this has been the case, I don't know). "Load Images" should be removed from the Page Info Permissions tab in Firefox, since it doesn't let you override the default to block or allow images for a particular website.

(I set permissions.default.image to 2 in about:config to block all images from everywhere then I went to www.foxnews.com and images were blocked. If I uncheck "Default" in Page Info > Permissions and select "Allow", then reload the foxnews page, images are still blocked. The Site Identity drop down will now show Permissions / Images with an Allow button and allow/block dropdown options but that doesn't do anything either.)

I can't find an open bug about the Page Info > Permissions option, "Load Images" which doesn't have any function. * I think you should file a new bug. Bug 416557 is about the Page Info > Media options that let you block images from individual websites. It's described in the Media > "Block Images from domain" section of this article. You can still block images from a particular website using the Media options. I tested it out and it does work, by scrolling down the list of images and selecting one, then clicking the box to block that domain.

[*] I did find this Linux bug, though, filed in 2011 for the firefox component:

https://bugzilla.redhat.com/show_bug.cgi?id=723545 Bug 723545 - Page Info: Permissions -- Load images -- block not working 

I edited the title of this thread to add "... and also "Load Images". So, what should we do about the Permissions "Load Images" section of this article then, since the "Load Images" option is still visible? Mention that this is a leftover from past Firefox versions that no longer works? Right now, it just says,

Load Images
Specifies whether the listed domain may load images automatically.

I also agree that the other info in the Permissions section (as well as the info in the entire article, while we're at it) should also be checked out for functionality but that should be another discussion.

On Permissions > Activate Plugins and other changes:
Getting back to the new Permissions screenshot, Activate Plugins section and other changes I made to this article, those changes still need review. Should my revision be approved in the interim?

Yes probably best to just go ahead with the changes and add a one liner about the Load images.

John99 said

John99, I'll let you (or anyone else) add the "one-liner" to the "Load Images" section (it's been broke this long, a little while more without addressing the issue won't hurt!)

I approved by revision as-is but didn't mark it ready to localize, with a "Need changes" entry on the Load Images issue.

underpass

In this paragraph:

== Load Images == Specifies whether the listed domain may load images automatically.

If, even after checking the "Block" checkcircle, your images are loaded each time you refresh the page or reopen some other time, then there might be a problem with a file. Load Images dialog

It is possible that there is a problem with the permissions.sqlite file that stores the exceptions.

You can try to rename of delete this file to reset all exceptions.

   Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder) 


not only is the content probably more appropriate to another kind of article (this is informational, not troubleshooting) but also the markup is not honored.

Thanks for your attention.

That paragraph was approved in this revision on May 28, 2014 and marked ready for localization a couple of days ago:

Diff: /kb/page-info-window-view-technical-d.../compare?locale=en-US&to=64353&from=51505

Yes, that paragraph seems to be out of place. I made a new revision and removed it but I'll leave it pending review to see if another reviewer agrees.

I also changed the thread title to: Reverting last revision (was: Format of a paragraph)

Thanks for pointing this out.

I did approve the paragraph in May with the intention of revisiting the article and possibly rewording some sections, but I didn't get around to that. I don't remember marking it for localization though. That might have been a mistake. Sorry about that.

I approved Alice's revision. I'll revisit the article later on unless someone else gets to it.

No problem, Joni.... forgive me for all these discussions :)

I made a revision to add "Use the Camera" and "Use the Microphone" under Permissions, based on this discussion in the Permissions Manager article kbforum:

Thank you for catching this, ideato. I've updated the article with mic, camera settings and updated the screenshots.

Tonnes, can you describe the other two ways of accessing permissions? I want to make sure we have those covered.

<snip> 3. On the same invitation page or when going to https://hello.firefox.com, one can also right-click anywhere on the page, choose Show Page Info and click the Permissions tab, showing a similar permissions view as in about:permissions [2], but per website as well. Note that these per-website settings are also included in the about:permissions tab, overrule the general "All Sites" setting (only shown there), and may not reside on top of each other or even at the bottom of the list, as they are displayed alphabetically when accessed via the Show page Info - Permissions tab.

Hi,

I've proofread the article. Great work from the writers.

Thanks. I've removed the "Needs proofreading" entry from the article description.

Thanks. I've removed the "Needs proofreading" entry from the article description.

Thanks for the update.

The article has been updated to make the "Security information for this page" subheading under "General" {for not fx33} (thanks to Joergen). That information was removed in Firefox 33 . Related bug: Bug 1029797 - remove redundant "Security information for this page" section of Page Info window

The article could use a new screenshot for the Page Info General panel without the "Security information for this page" part of the panel, so I'll add a Needs change" entry.

P.S. Here's the image currently used in this article for the General panel: [[Image:Page Info - Win1]]

Page Info - Win1

Once a new screenshot is added for fx33, The above screenshot < should be made for not fx33.

I made a new screenshot. I also removed the pre-fx29 content and updated the instructions to open a window for Firefox 42.

can we also list the permissions in the article in the order they are showing up in product as well?

Here's the Firefox 41 Page Info Permissions panel, from the Fx41PageInfo-Permissions2 image I just uploaded:

Fx41PageInfo-Permissions2

The article currently lists the Permissions in the same order:

   Activate Plugins
   Access your Location
   Enter Fullscreen
   Hide the Mouse Pointer
   Install Add-ons
   Load Images
   Maintain Offline Storage
   Open Pop-up Windows
   [*]
   Set Cookies
   Show Notifications

   Use the Microphone

[*] We'll have to add "Receive Push Notifications" for fx40 and above. Related discussion: https://support.mozilla.org/en-US/kb/permissions-manager-give-ability-store-passwords-set-cookies-mo... [Fx 40] default permissions need update for "Receive Push Notifications". ... which links to the related bug (fixed in Firefox 40): Bug 1038811 - Implement Push API

ah i get it, then the issue is only a localisation issue as the permissions (except plugins) seem to be sorted alphabetically and therefore the order is diverging in other languages from en-us

New screenshots for Permissions panel showing only the Flash plugin:

... to use {for fx40} https://support.mozilla.org/en-US/gallery/image/23475 Fx41PageInfo-Permissions1

I made a new edit based on philipp's pending revision, to include new screenshots and a Permissions subsection ""Receive Push Notifications" for fx40 and above. (It's pending review)

Still need a new Permissions panel screenshot for fx42 with "Enter Fullscreen" gone so I set up another "Needs change" entry for that.

Speaking of screenshots, is there any reason we are only showing the General, Media, Feeds, Permissions, and Security panels for Windows?
