Facebook and Instagram cause Zen Browser to freeze completely
UPDATE: Just found the issue. It was Adguard all along, causing facebook and instagram not to load. Although I disabled the extension but I had adguard installed on windows and it was causing the trouble. However, the problem only occurs on Zen, and not on other browsers!
Steps to reproduce:
- Open Zen Browser.
- Visit either of these websites:https://www.facebook.com/ https://www.instagram.com/
- The page continues loading indefinitely.
- After this happens, the entire browser becomes unresponsive, and no other websites will open.
- Close Zen and try to reopen it.
When reopening the browser, I receive the following message:
“Zen is already running, but is not responding. The old Zen process must be closed to open a new window.”
After closing the old Zen process, the browser works normally again. However, the problem returns as soon as I open Facebook or Instagram.
Extensions and troubleshooting:
- Extensions in use: AdGuard Browser Assistant, IDM Integration Module, linkding extension, Proton Pass: Free Password Manager, Return YouTube Dislike, SteamDB, Stylus
- Tested with all extensions disabled: No
- Tested with a new profile through
