Hello FF community. I come here for a question, maybe a confirmation (I'm gonna try to be as short as possible ).

I'm using for years infamous Aris-t2 customCSS. I'm about to "jump" from FF v88 on my desktop to V115.0.3esr. I tested everything on my laptop, and set everything on the customCSS so it looks like my actual V88. It's almost identical, but one thing is bugging me: the scrollbar.

Scrollbar on FF115 isn't the same anymore than in V88 as you can see on the screenshot I posted (test scrbr for V115, scrbr2 for V88). The clean one with "3lines grab button" I actually use is less "eye catchy" than the new one. I've made some researches, and apparently, starting FF V97 about 2 years ago, scrollbar has been change to use W10 "flat like" one, and at FF106+, every older code was apparently removed. I tried to changed a few things in about:config, like "widget.non-native-theme.enabled" or multiple commands about scrollbar, nothing changed.

So I just wanted to know if someone could confirm me that the old scroll bar I use is now impossible to get back, or if there's a command I miss that could do the thing.

Thanks, have a nice day ^^

My Linix Mint will not auto update. I have down loaded update, but will not update. I have gone into the "Terminal" to update everything, would not update. I have FireFox 88 and need to get 107 on my system so I can access some sites. Any help would be great.

Thank you Paul

I'm sure I'm not alone in having an old email address stripped off the server when changing broadband supplier. Unfortunately, most services use email as user ID, hence I have an old F'fox a/c - my first - for which I have long since forgotten the password, which uses just such an email. As a consequence, I can neither change the email nor delete the a/c - F'fox seems to insistst on a user knowing a/c password in order to change email (understandable), or delete the a/c (slightly less understandable). So it 'helpfully' tries to send a password re-set link to ........the a/c email, which of course no longer exists & thus I cannot access. May be just my (mis)perception, but because this was my first a/c, F'fox seems to default to the now inaccessible a/c - one reason why I wish to delete it. Is there another method whereby I can delete this old a/c, or is it doomed to wander the ether for eternity?

I use Linux, but know nothing about it. My brother installed Mint on my desktop; he was my Computer Guru, but he has passed away. I need to update from FF88 to at least 99. Can you help me, please? Many thanks if you can.
