When Firefox updates, it's an extremely frustrating experience. Enough so that I'm about ready to switch over to Chrome (I already use it for work). Every single time, websites suddenly can't load and all my extensions stop working. It's happening now! I'm writing this from Chrome.

I'm frankly not sure when or why websites start loading again, but it seems to take about a day for things to get back to normal. I've tried closing and reopening Firefox, but that doesn't seem to do anything. It just takes time. I have a 2017 MacBook, OS Catalina 10.15.3.

Is this a known issue? I see all kinds of possible solutions when I try and look for some myself, but oftentimes the OP says they didn't work and then people offer other solutions. I'm wondering why this seems to happen, and if there's a suggestion for how to fix it once and for all—I've never had this problem with Chrome.

MacOS Catalina - setting security.enterprise_roots.enabled to true - Doesn't work as expected

When a user, on a MacOS Catalina, sets the security.enterprise_roots.enabled to true in Firefox, the certificates are not read from MacOS keychain store.

The method used to set the parameter to true:

Use Firefox on MacOS Catalina, type 'about:config' in the address bar. If prompted, accept any warnings. Right-click to create a new boolean value, and enter 'security.enterprise_roots.enabled' as the Name Set the value to 'true'

What is your recommendation to bypass this problem without manually importing the certificates in the FF certificates authorities ? The goal is to read the certificates from the system store. This parameter works perfectly on MacOS Mojave & Windows.

I just upgraded to to Mac OS Catalina and Firefox 75, and I've noticed two very strange and specific problems on certain websites.

-On Wikipedia the number 9 is displayed as an underscore _ So the year 1669 looks like 1__9, etc.

-On Blogger, in the compose mode, typing lowercase y makes nothing appear, and typing lowercase z produces quotation marks!

I tried using a different (brand new) keyboard, and the problem remained.

I tried those two websites in the Safari browser, and there were no problems.

Today I update MacOS Catalina and the same as the update some weeks ago Firefox is removed. I could not find the app anymore (the dock presented a big ? at the place where firefox was.) Last time I downloaded and re-installed Firefox, but today again all is gone after the automatic update of Catalina. On my iPad and iPhone there are no problems. Now I did remove all remaining Mozilla files on the Mac and are prepared to download again.


Why is the app removed? Or must I adjust the installation
