Hello, I'm running Firefox 78 on fresh Debian Stable installation and I cannot access certain websites. I followed step-by-step the instructions by Mozilla Support found here, with no result. Of course, I tried completely uninstalling and reinstalling Firefox, renaming .mozilla folder to create a new settings folder, deleting .cache/mozilla etc. I use no proxy, and I can visit all those certain websites form other browsers of this installation. And I'm looking for a solution for more than 2 weeks now. Any help is welcome!

被選擇的解決方法

Solved but not suggested:

Solved in the next Firefox release (93.0).

Please be aware that Firefox 93 for .deb based distributions is depended on libc6 2.32-4, while Firefox 87.xx is based on libc6 2.31-14. Using libc6 libraries (fundamental for all Linux distributions) from Debian unstable in a Debian stable installation, may cause serious dependency breaks in future.

For me, I hope that within the next 2 months, all packages marked now unstable, will be delivered in stable repositories. In case somebody looks for a solution, If I face any trouble, I'll let you know.

I always see this message if the page is not displayed. Please see the attached image. First time that I realized that, was when I tried to visit the page nikas.tech

From the logs of the server I can see:

[client 37.6.31.52] ModSecurity: Access denied with code 403 (phase 2). Matched phrase "Mozilla/5.0 (X11; Linux x86_64; rv:78.0) Gecko/20100101 Firefox/78.0" at REQUEST_HEADERS:user-agent.

I don't know about this and I called for more help.


Make sure you are not blocking content.

Diagnose Firefox issues using Troubleshoot(Safe) Mode {web link}

A small dialog should appear. Click Start In Troubleshoot(Safe) Mode (not Refresh). Is the problem still there?

Thank you for your help.

I'm not blocking content. I have no firewalls or other relative applications. It's a fresh Debian Stable installation. I've already tested FF safe mode with no result. I have already try to Turn Off the Enhanced Tracking Protection for these websites. Problem remains in Private Browsing as well. I tried not only to clear FF cache using FF's menu, but also switched off FF, and renamed /home/myusername/.mozilla and /home/.cache/mozilla folders, where in Linux profile and cache is stored.

As for SmartBlock, I followed your link, but in my configuration editor there isn't "extensions.webcompat.enable_shims" preference.

Finally, I upgraded FF to 93.0 from Debian unstable repositories, and it's all fine. So??? Seems it was a version problem, right? Should I fill a bug report?
