Forum zgromaźeństwa Firefox

For some time now i have had issues with the browser. I get many warnings on Facebook and elsewhere that my browser is not up to date. Even the weather channel does this and now blasts me with ads , as before i had ad blockers and now I do not. I have downloaded both 16 and 32 bit Firefox for Linux several times to no avail.I need simplified help as I am not that tech savvy and it is important to me as i spend much time doing activism , signing petitions and passing on the truth. Thank you in advance

Downloaded an update of firefox. Is this for real? A message box came up and said I would get a NEW version of firefox but all my things would be saved. Now I have two firefox versions. My old version has all my info and saved and/or chosen settings. HOWEVER the newer version is a new install without settings and WORSE it has GOOGLE as the browser?!?! Is DUCK DUCK GO gone to goOgle? If I wanted a shopping app I would use my GOOGLE account instead of Firefox. How do I fix this?

After auto updating this morning, my entire profile was pretty much broken, no history, tabs, bookmarks, plus cookies and local storage seeminlyg disabled, strict browser privacy enabled.

I was able to restore the profile from my TimeMachine backup to before the update and recover history/bookmarks etc, but now it claims the various databases are readonly/not accessable.

My only viable solution has been to install Firefox 141 and copy my restored profile data into a new profile created by Firefox 141 (not Dev Edition). Firefox doesn't think the same DBs are read only.

Running Dev Edition 142b1 against the same fresh profile generates the errors attached. NS_ERROR_FILE_ACCESS_DENIED suggests permissions, but I have double checked all those, but given Firefox runs these fine, this looks to be a bug in Dev Edition
