Quick guide: popup user interface - uBlockOrigin/uBlock-issues GitHub Wiki
- The large power button
- The per-site switches
- The number of requests blocked
- The tools
- The number of domains connected
- The overview panel
This is uBlock Origin (uBO)'s popup UI when you click on uBO's icon in the toolbar:
The amount of visible information can be adjusted by clicking on the "More" and "Less" buttons:
Click the large power button to turn off uBO for the current site (add current site to Trusted sites list). This will be remembered the next time you visit the site.
Alternatively, you can also Ctrl-click to turn off uBO only for the current page (Cmd-click on Mac).
For more advanced control, see "How to mark a website as trusted".
The per-site switches allow you to control some settings on a per-site basis. See detailed documentation about per-site switches.
Shows the number of blocked network requests on the current page. The number of network requests blocked since installation is also displayed. (This is less useful; however, users appreciate this information). The percentage indicates the number of blocked requests out of the total number of requests made.
Look at the advanced setting requestStatsDisabled if you don't want to keept "Blocked since install" data between browsing sessions.
The number of distinct domains with which a network connection was established, out of all connections (established + blocked). The domains are derived using the official Public Suffix List.
In general, it must be assumed that each distinct domain is managed by a distinct administrative authority. In practice, it is not uncommon to have multiple distinct domains which are under the same administrative authority (example 1: google.com, ajax.googleapis.com and gstatic.com, example 2: wikipedia.org and wikimedia.org).
That said, this statistic may be seen this way: the more distinct domains your browser connects to, the greater the privacy exposure.
In a best-case scenario, the number of distinct domains to which a web page connects should be only one: that of the remote server from which the web page was fetched.
The higher the number, the higher you are exposing yourself privacy-wise.
There is a good correlation between the domains connected count and: unneeded page bloat, high privacy exposure, increased likelihood of being the target of data mining.
Example: the web page on https://www.ibtimes.com/ (which can be read fine in all cases, by the way):
| uBO's mode | turned off | default settings | default-deny |
|---|---|---|---|
| domains connected |  |
 |
 |
| privacy exposure | very high | medium | very low |
| bloat | ridiculously high | medium | very low |
And I had click-to-play enabled in all cases, so it could have been worse (except for default-deny)...
Click the flash icon to enter element zapper mode, which allows you to interactively remove one or more elements on the current page. Removing an element is always temporary, i.e. the removed elements will be back when the page is reloaded.
Note
This button will be missing when "My filters" list is disabled!
Click the eye-dropper icon to enter element picker mode, which allows you to create a filter by interactively picking an element on a page, thus permanently removing it from the page. The filters created through the element picker are added at the end of your own filter list in the My filters pane in the dashboard.
New in 1.39.0.
The "chat" icon opens the "Report a filter issue" form, which makes it easy to report filter issues with specific websites to the uBlockOrigin/uAssets issue tracker.
Reporting filter issues requires a GitHub account, since uBO does not have a home server through which reports could be sent.
The report icon is available only when uBO is enabled on a given site.
Click the list icon to open the logger in a separate tab. This allows you to inspect real-time network traffic, DOM elements cosmetic filtering, scriptlets injection and so on, within the browser.
Tip: press the Shift key while clicking the icon to toggle between opening the logger in a separate window or a separate tab. uBO will remember that setting when you open the logger without the Shift key.
On mobile devices, the "Open the logger" icon is replaced by the "chat" icon ("Report a filter issue" form), since it is more likely to be useful on small display devices. The logger can always be opened via: Dashboard > Support > Filter issues/website is broken > Tips > The logger (clicking the link). Then also optionally a browser bookmark can be added to easy access in future (note: after every clean installation of uBO, uBO gets its new unique identification value, hence the bookmark needs to be recreated again from the scratch). The logger icon can be also turned back on permanently in advanced settings. Also more information and visual guide are available in issue: logger missing in fenix (android).
Click the gears icon to open the uBO Dashboard.
Clicking on the "More" button will expand uBO popup panel to the point where it will show you a list with details about requests blocked and domains connected on the page:
Clicking the empty space before a particular domain name or the all cell in the first row, will toggle on/off subdomain-level details.
The panel will also be expanded when you enable "advanced user" mode -- this is only for convenience -- it will not close automatically when "advanced user" will be disabled. To hide that panel, just click on the "Less" button to adjust it to show only the information you desire.
The colored bars near the left edge will give you the general overview when network requests to particular hostnames are all blocked (reddish), all were allowed (greenish), or some were blocked some were allowed (yellowish). The more distinct, wider bar denotes the root context - the hostname for which local rules and filters are created.
The pluses and minuses will give you slightly more information, their number is proportional to the number of requests that were either allowed or blocked:
-
+,-: under 10 network requests were allowed, blocked. -
++,--: under 100 network requests were allowed, blocked. -
+++,---: 100 or more network requests were allowed, blocked.
Starting with 1.24.3b7 canonical name (CNAME) hostnames are rendered in blue font. The uncloaked entries in the popup panel will also show the related aliases (in smaller characters underneath the canonical names):
Starting with 1.52.0 a firewall filter widget has been introduced, hover over the blue filter symbol at the upper left corner, and click desired labels, the panel will squeeze a bunch of lines together, click again to unsqueeze. The idea is that some people might want to only see what's blocked, since it's these rows that are of interest when trying to unbreak a site:

Unless you are in "advanced user" mode, the overview panel is read-only and available only for informational purposes.
I am an advanced user!
In "advanced user" mode, this panel is fully interactive and can be used for advanced filtering control:
Refer to the Dynamic filtering documentation to learn more about the rules.
After modifying the rules, you can quickly reload the page without leaving the popup by clicking on the reload button appearing in the top-right corner. Click it with Ctrl, Shift or Cmd (Mac) pressed to bypass browser cache (also see cache related issues: Dynamic Filter: 3rd party scripts not blocked if in cache and uBO's own reload button does not do a cache-invalidating reload.
Click the all cell at the top with Ctrl and Shift pressed to open the popup panel as a new browser tab, which may be useful for example to capture screenshots.
