How to kill a good browser?
Rapid Release new versions every 6 weeks so 3rd parties don’t have time to update add-ons.
Mozille took a good browser and is killing it.
I stopped at FF 15 because every new release had new conflicts and problems with add-ons, Java, Adobe Flash and PDFs.
It wasn’t worth trying to keep FF updated. Also, FF has effectively become bloatware.
Google has done fairly rapid regular updates to Chrome and I haven’t had any significant issues with browser extension updates (Symantec has been very timely with updates to the Identity Safe extension from Norton Internet Security).
