Anki Add-ons Failed to Load

I followed a tutorial by Anki King on how to install add-ons, and now I am faced with a series of error messages when opening the app on my MacBook. I tried holding the shift key when opening the app, but I cannot get into the main page because the error messages close my app before it can even open.

Here is the first of many error messages:

An add-on you installed failed to load. If problems persist, please go to the Tools>Add-ons menu, and disable or delete the add-on.

When loading ‘⁨Browser Resizer⁩’:
⁨Traceback (most recent call last):
File “aqt/”, line 230, in loadAddons
File “/Users/kathymai/Library/Application Support/Anki2/addons21/1435775540/”, line 30, in
Browser.updateFont = wrap(Browser.updateFont, updateFont_wrapper, ‘after’)
AttributeError: type object ‘Browser’ has no attribute ‘updateFont’

It seems add-ons didn’t actually get disabled. Try holding down shift again, maybe Anki is opening before the press is getting detected.

The issue here is caused by the Browser Resizer add-on.


I think I was holding the shift key too soon, like you said. Thanks so much!
