Can’t launch Firefox 3.5.19 on Linux Ubuntu When trying to run with:

./firefox

Terminal gives the following:

./firefox-bin: error while loading shared libraries: libdbus-glib-1.so.2: cannot open shared object file: No such file or directory

After many years of successfully using Mozilla Firefox, the last few weeks I noticed a problem that gradually progressed that made it difficult to add a single Bookmark. Now the Bookmark displays only: Manage Bookmarks, Bookmark Current Tab, Search Bookmarks, Bookmark All Tabs, Bookmarks Toolbar, Other Bookmarks, Mobile Bookmarks. Not only could I not add the new Bookmark but I no longer could view ANY of my Bookmarks created over the years. This error started out easily corrected by going to different website and then back to the one that I wanted to save. Today, that did not work and no matter what I tried including completely shutting down and turning back on my computer to the Firefox browser, I could not add ANY website to bookmark. What I tried next was to sign out of Firefox which required me to create a new password because the previous one created was not accepted. After creating a new log in credentials I then tried to use Sync to retrieve my data which was unsuccessful because no entries under Bookmarks were present. What if anything can I do to retrieve these important Bookmarks? Thanks

I was in the middle of a bunch of work and this Avira pop up showed up blocking 1/3 of the screen. Probably a scam, but no way to get rid of it. Finally I had to reboot. I googled options and none of them worked. I have been getting Avira "scare tactics" but they were easy to close. But this was extremely annoying. If this continues, how to I get rid of it??

when attempting to move Firefox bookmarks to my new computer, I click import data within the Firefox page. The computer asks me to select the file. I have no idea where the bookmarks reside and cannot find a file. What is the procedure to get this done?

I keep getting pop-ups in the right lower corner from "mozilla firefox" (not sure if they are legit). They will say: "zeus.2020 trojan detected" or "virus detected" or "system is infected", etc. All have "Mozilla Firefox" in the upper left of the pop-up, and "via rgfirewall.xyz" at the bottom. Is this truly legit, or is it just a nuisance? I've just been closing them with the x or dismiss buttons.

While using Outlook.com email in my Firefox browser, I attach a zip file to send to someone.

They reported that the zip file is empty. This happened two more times.

I confirmed that the zip file that I was uploading from my hard drive did indeed have files included.

I then downloaded the attached zip file from the email in my "Sent" folder. It was empty.

When I tried using "Outlook.com" in the Chrome browser, I did not have the same problem.

I'm using Firefox ESR version 128.9.0, on Windows 10.

(The downloaded empty zip file also had "utf-8" added to the file name - that problem is addressed in other tickets and is being worked on. I am not asking about that.)

Is there anyway to force actual mozilla pages to be displayed in a dark mode instead of the blinding white background that hurts my eyes to view ? Thanks, David

Good day After the last update, the browser changed the appearance of the YouTube player. In all other browsers it is standard, please help return it to how it should be

I'm trying to switch from Chrome to Firefox after getting pissed off that Chrome removed Unblock Origin. I'm using Ubuntu 24.04.

My Yubikey worked on the snap version of Firefox but I got rid of the snap version because it was consuming 40% CPU to use Google Meet. The apt version uses less CPU, but now my U2F keys don't work. Any website that says "Touch security key", touching the security key does nothing. No feedback whatseover.

What gives?

This is a horrible UX. Installing a browser and having it work optimally out of the box should be a one click thing.

Initially connects video playing to Headphones via Bluetooth then audio stops. Reloading doesn't help. But the same works perfectly on other browsers. Problem is with Firefox audio setting. The problem started only a week ago for firefox

What happened to the box (on the left/center of the screen )that had all the icons of plugins you can drag and drop to your toolbar (like the printer icon)? Can someone tell me how to get it back? There used to be a way to get to it by tapping on the 3 bars in the upper right of the screen and going down the options.

One more thing. Some times, when I am typing, a "toolbar" shows up at the bottom of the screen. Why is that?

I have a couple questions on tab groups, I'm a new ms edge refuge but this not as smooth as I would like :). I realize tab groups are oddly new for FF, but I'm trying to get setup and running into two main issues. 1. I cant seem to freely reorder the tab groups, I can move the individual book pages no problem but not the groups as a whole. I would expect to be able to left hold click drag the order of the groups just like individual tabs. 2. Tab groups don't seem to exist across clients (or maybe I'm missing the how). If I open FF on my mac I would expect to see or at least be able to reopen the same tab groups as my windows PC, not just the individual pages from history on other device. Is there a way to do this? 3. can't import tab groups from edge? You don't want to make it easy for folks to switch?

Thanks, if I missed something happy to learn.
