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.

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 ^^

Hello, I have a very odd problem with my firefox browser. I am running firefox 88 64bit on a 16.04 (I know...) Ubuntu. On certain websites, I have an issue with interactive content: www.leboncoin.fr will not let me login anymore (quite recent) www.decathlon.fr will have trouble displaying user comments, images, let alone placing an order Now and then websites with dynamic content and forms will not load...

I am not sure what is the link between all these but it seems related. I have tried the troubleshoot mode but it does not change anything. At the moment when I need to use these king of website I have to switch to another browser.

Thanks in advance for your help!

Bangirot says technical problems when I want to see my received bankgiro payments. Win10 with Firefox, I can't see payments on that machine for a month soon. I have reinstalled firefox now. Still same result. With Android phone and firefox it works, but without printer. With another browser on Win10 it works, but not with firefox. Swedbank internetbank or bankgirocentralen can't help me. They have not heard of such problems.

Internetbank works, but with their connection to bankgirot it says, tehnical problems. If I login to bankgirot directly, it says tehnical problems.

So far its only the combination with this machine and firefox that gives this result. I haven't tried with another machine yet.

I have used firefox very long time without any problems.

Hi everybody. Thanks in advance for your help.

I'm on Win 11 23H2, and I'm currently running Firefox 88.0.1 x64. Why? Because it's heavily customized to suit my needs. Some examples:

• Extensions (e.g. Classic Theme Restorer)
• userChrome.css and userContent.css customizations ( https://github.com/aris-t2/customcssforfx ), which include tabs on bottom (mandatory for me), tab height/width, and many other things.

I decided a long time ago to stay with v88 because every new Firefox update was breaking things that I needed, and I got tired to spend hours with every new update. If only Firefox devs could find a way to NOT break user customizations with every new update...

Of course I'd like to update my Firefox to the latest version. But I know that it's going to be a nuclear bomb. I already made a test. First I made a backup of my profile folder, then I just updated Firefox. Suffice to say that not only all my customizations disappeared : even my tabs disappeared, and I have dozens of them. So I had to uninstall everything, copy back my previously saved profile folder (because of course it had been modified by the latest version), and reinstall Firefox 88.0.1.

So here's my plan and my question. Would it be possible to have two different Firefox installs (not portable I guess), with two different profiles, running at the same time?

• Here's how I see it:
• Download Firefox latest version
• Close Firefox 88
• Move profile folder away from AppData\Roaming\Mozilla\Firefox\Profiles, so Firefox latest version can't find it
• Move Firefox folder (the one within Program Files) so hopefully Firefox latest version can't find it
• Install Firefox latest version (it then creates a new user profile folder)
• Start Firefox latest version
• Move back the old Firefox folder to Program Files (so there will be two different Firefox folders, e.g. "Mozilla Firefox 88" and "Mozilla Firefox")
• Move back the old profile folder to AppData\Roaming\Mozilla\Firefox\Profiles (so there will be two different user profile folders)
• Start Firefox 88

Would that work, or am I missing something?

If it worked, then I could keep working on Firefox 88, while gradually customizing Firefox latest version until it's ready to take over.

Thanks in advance for your insights!

I have two Firefox email systems. One works perfectly. The other suddenly stopped showing the screen of inbox messages. I can scroll over the blank space and the message will display in the lower part of the monitor, but not in the upper screen of subjects, sender, date. How do I return to default setting?
