I am going to collect here common usage issues users may face.

The best way to troubleshoot uBlock is with uBlock: the logger will tell you what uBlock is doing when you try to load a web page. Using the logger is the first thing you should try when you are trying to find out why a page does not load/display as expected.

Firefox: uBlock's popup UI is not displaying

You can fix this by following the following steps:

  1. In the navigation bar (Awesome Bar) enter about:config
  2. Click on the I'll be careful, I promise! button
  3. Search for ublock0
  4. Double click on extensions.ublock0.forceLegacyToolbarButton so that the value = true
  5. Restart Firefox

Firefox: Missing icons in uBlock's popup UI

You can fix this by following the following steps:

  1. If you use a Linux system go to Edit - Settings - Content and choose a default font other than "serif". "Liberation" and "Clear" are known to work.
  2. If the icons are still not showing enter about:config in the navigation bar and promise to be careful
  3. Search for fonts
  4. Check that gfx.downloadable_fonts.enabled is set to true. browser.display.use_document_fonts can be set to 0.

Links to social networks are blocked

Because you enabled "Fanboy’s Social Blocking List", or one of the filter lists which includes it, like "Fanboy’s Annoyance List" or "Fanboy+Easylist-Merged Ultimate List".

My antivirus flags uBlock

False positive.

uBlock ships with malware filter lists, and this causes false positives in some antiviruses.

"NETWORK FAILED" error when I try to install uBlock Origin from Chrome store

Unfortunately, your Chrome browser executable has probably been tampered by malware:

At this point we're pretty sure that this error is primarily caused by malware / unwanted software on your machine actively tampering with the contents of the chrome binary and your user profile directory data

You will need to clean up whatever malware tampered with your Chrome browser installation. Starts here: Malwarebytes Anti-Malware

uBlock Origin uninstall itself

This has been reported many times. This could be caused a false positive from your anti-virus application.

Specifically, it has been confirmed Avira Anti-virus has been uninstalling uBlock Origin.

Unable to open links in new tab

If you answer "yes" to both questions above, this is your problem (from link above):

Caveat for Chromium-based browsers: Due to Chromium API limitations, it's not possible for uBlock to determine for sure whether a new tab being opened is that of a popup, or is the result of a legitimate click on a link by the user. So if the no-popups switch is in use, you won't be able to open a link in a new tab through the context menu.
