Avast Premium Security smart scan classifies Firefox browser version 115.19.0 as outdated and wants to download version 128.6.0. Since I use Firefox under Windows 7, the latest version available is 115.19.0. 128.6.0 can be downloaded for Windows 10.
Untick and ignore especially as your on 7 and the latest version is for 10/11
after my last scan it said Firefox neded updating when in fact it was on a later version than avast said i needed.
As youve decided to stick with 7 then you take the risk of all the possible risks of old software, programs and windows updates which will no longer protect you without the latest programs.
I took the plunge and bought a new 11 laptop but hate it.
when i get the chance im going to change all the workings to make it look and run like windows 7 which has been the best OS.
My windows 10 looks and feels exactly the same as 7 which has been great as i also didnt like 10.
