In a fleeting instant, it appeared as though I’d been denied access to one of my most potent extensions in Microsoft Edge. Upon settling down at my workspace this evening, an unexpected influx of advertisements greeted me. To my astonishment, uBlock Origin seemed to have ceased functioning within Microsoft Edge.
As a devoted user of uBlock Origin, I found myself in a pickle when clicking its extension icon seemed to have no effect at all – leaving me helpless to block any unwanted content across websites. Fortunately, the brilliant community over on the Microsoft Edge subreddit came to my rescue! They managed to unravel the mystery and shared some valuable insights.
The creator of uBlock Origin, known as “gorhill,” admitted on GitHub that an error had occurred, causing him to temporarily remove uBlock Origin from the list.
Yesterday, I made a mistake. Instead, I used the uBO extension ID to upload uBO Lite (since I was revising the upload script with the intention of simplifying the process).
It seems there’s no rollback feature in the dashboard of the store where I manage my extension. As a temporary solution, I took it down from the store because I couldn’t replace the current version (1.65.0) when it wouldn’t let me do so. I suspect this is happening due to the store not accepting new MV2 extensions anymore, considering the new upload would be seen as an MV3-to-MV2 extension upgrade. Unfortunately, I haven’t found a quick fix for this issue, so I had no choice but to unlist the extension in the meantime.
I figured one day I would mess up big by mistake, well yesterday was that day.”
The issue has since been resolved and uBlock Origin is back in the Microsoft Store.
It might come as a shock that despite a significant part of my job involving people viewing ads alongside articles I produce, I personally utilize an adblocker. However, the importance I place on ads generating revenue is a key factor behind this decision. The versatility of uBlock Origin enables me to show trust in specific websites and block specific types of ads that are particularly intrusive.
While there are alternative ad-blockers such as uBlock Origin Lite, I’ve been relying on uBlock Origin for quite some time due to its robust features and adaptability. I’m familiar with its interface and functionalities, and changing to another ad-blocker might feel inconvenient for me because of this comfort.
How to restore uBlock Origin on Microsoft Edge
Fortunately for users of uBlock Origin, they can once again utilize the extension, as the problem that arose previously has been resolved. This issue specifically impacted individuals who had already installed uBlock Origin prior to the error occurring.
For those who find themselves impacted by the problem and belong to that specific category, simply uninstall uBlock Origin from Microsoft Edge, and afterwards, re-install it via the Microsoft Store.
Even if uBlock Origin isn’t available on the Microsoft Store, you can still utilize the extension by accessing developer mode within Edge. Here’s how: Navigate to the settings of your Edge browser, enable developer mode, and then manually load the file from the uBlock Origin GitHub page. It’s useful to know this process in case a similar issue arises again. The official releases page for uBlock Origin provides instructions on installing the developer build across various web browsers.
Instead, you might have easily obtained uBlock Origin as Microsoft Edge also allows for the use of Chrome extension, making it accessible from the Chrome Web Store.
Did Google block uBlock Origin?
The solution to this issue is complex due to adjustments Google implemented in Chrome that interfere with uBlock Origin’s functionality. These changes are integral to a broader transition from Manifest V2 to Manifest V3.
Despite having ample time to transition extensions from Manifest V2 to Manifest V3 before Chrome discontinued support for the former, the developers of uBlock Origin found that they didn’t have the same luxury with their specific extension.
In simpler terms, the Manifest V3 update restricts the WebRequest API, a crucial tool for ad-blocking extensions like uBlock Origin. This API helps these extensions prevent specific content from being loaded, a key feature they provide. Consequently, uBlock Origin can no longer work harmoniously with Google Chrome due to this change.
uBlock Origin Lite can be used on Chrome and various other web browsers, however, it doesn’t provide the same level of options as the complete version of uBlock Origin.
Manifest V3 was designed to offer enhanced security over its previous version and improve overall performance. Unfortunately, this upgrade resulted in the unintended consequence of no longer supporting uBlock Origin within Chrome.
In contrast to Chrome, which stopped supporting Manifest V2 extensions, uBlock Origin remains functional within Microsoft Edge. However, Microsoft’s documentation regarding the deprecation of these extensions in Edge has been somewhat ambiguous. Despite the tech giant declaring that Manifest V2 extensions will eventually cease to work in Edge, the exact timeline for this is still undetermined and listed as “TBD.
It is not unusual to see an unknown or undetermined time frame (TBD) in project development timelines. However, extending that uncertainty for such a lengthy period is quite uncommon. For at least half a year, Microsoft has left the end date of Manifest V2 extension support undecided (TBD).
