The problem with Firefox like all new browsers today is it is very bloated and slow down your computer if you have a old computer.
I have not had any problems in past month or two of Firefox freezing or crashing. It just bloated and slow down old computers.
The mobile version of Firefox for IOS is not great at all and the Firefox for android is like a kid under the age of 12 will probably put better Firefox than what they have for android.
Well sadly Firefox has low market shares and the dev team don’t put any where close to time they do with the desktop version.
Where you replying to my post I made above some days ago Daniel Bora?
