Yes, that's what I was afraid of... I still don't know if it works in 14.1 and I won't be able to try it for another 10 days or so. Thanks for the report!
My Firefox 60.2.0esr (64-Bit) installation works fine. It seems to me that the pages are loaded and displayed a bit faster. I have slower internet and old PC hardware. I had previously uninstaled the previous version and then installed the new version and kept the profile.
Then I manually removed the previously installed NoScript version and added the current version (10.1.9.1). The same with "Video Downloadhelper" (7.3.5).
When Firefox quits, I let delete the entire history. With every OS shutdown, I let delete all caches, including those of Firefox. That could also have influence.
Last, galmei, if you include these lines in ~/.profile, you will never again have to delete the content of ~/. cache as no software that I know will continue to write in it.
