As usual would be better if you talk about something you understand. In this case you failed to do that even after I patiently explained why a *REAL* portable version is not possible w/o patches You need the flag --disable-machine-id which is not there in unpatched flavours.
No, I didn't test it was just a remainder for people obsessed by the "last update" paranoia, to make them uncomfortable
I tested it, everything works fine. Of course, not installed, but unpacked with 7-zip and overwritten the files in Program Files (just like I install/update it anyway). That's FF 116 on Win7. I read somewhere that Nightly 117 doesn't work on Win7 (they use a new API call), but I didn't catch if it was only the installer or not.
Yeah, v116 is seriously the last one that supports windows 7 despite support ending on v115. Then the API change requires windows 8.1 & above for now. No idea how long windows 8.1's api will work with Firefox though but Firefox v118 still runs on windows 8.1 without issues. Though you have to use cff explorer to edit it or supposedly install it on a windows 10 machine & copy the install from windows 10 to 8.1 Also, supposedly the latest opera still works on 8.1 if you change things using cff explorer. Though what you have to change no idea.
Version 116.0 would not install for me in Windows 7 Professional SP1 64-bit. It displayed an alert which said Windows 7 and Windows 8.1 is not supported. I am currently using version ESR 115.1.0.
Read the last posts. Blocked in the installer, but extracting the files and overwriting the old ones presumably works. Not useful, as 115ESR gets longer support, anyway.
Companies artificially blocking updates on operating systems that have no problem running that software if a little string says NT=10. It happened with „Windows Vista“ and now with „Windows 7/8/8.1“ Of course some software that have edited kernel system changes, API calls that simply don't exist or etc. that need heavy work to be adapted are fine in saying to be not supported, but if I can CFF edit and the software runs fine, then that's just sad. Not to mention all of these „Your operating system is not supported since 2020“, the thing is they just ignore ESU, which is in the furthest 2024 and it's quite easy to get it running (Thanks to MDL and the devs here of course). I do wonder what „Mozilla“ is going to do (They do have „Thunderbird“ which is tied to „Firefox“, I haven't seen any posts about that) and „Steam“ the most, they really shot themselves's in the foot (Running „Chrome 85“ for years and then complaining that „Supporting „Windows 7/8/8,1“ can't be done, because security) If they really did care, they would have updated to 109 a long time ago, but to this day, it still reports itself as V85, call it „Top notch security“.
Because it is (by far) the best browser out there? Already explained many times, just take your time, read, and try to understand what you read.
