On many of the sites that require hardware key for 2FA, what I should get is a prompt to press the Yubikey button, but instead I get a technical error. This has happened with logging into Google and Vanguard. Both use Yubikey as a 2FA.

I did not encountered this issue on Micrsoft Edge. I am running this on Windows 11 24H2. I believe it used to work.

I was experiencing that one bug that locks the sidebar from opening on hover (even with the option enabled) and I was somehow able to change the size of the sidebar while trying to get it to start working again (IDK why I didn't just close and reopen my browser because I know that fixes that) and now my open on hover sidebar is the biggest it can go and it is genuinely unusable. I can't change the size of it while it's on the open on hover option, but changing it back to the fixed/static sidebar and then editing the size does not carry over when I re-enable the open on hover option. Objectively, this is really dumb and kind of hilarious. I know I am dumb for this.

Recently I added new profile to Firefox. Since then History tab does not work. There is no pages in History tab. In settings History is enabled. This function works properly in my original profile.

On screenshot you can see that I opened at least one page, but in history there is still no pages. How I can fix it?

I do not like the blue background behind My sidebar bookmarks . Is there a way to disable/remove the blue background when using bookmarks sidebar? I am not familiar of how to use syntax editing (I guess its called that), I just need layman terms if possible.

Hi there just switched to firefox due to some unfixable bugs in Edge, but i'm missing a key feature: in edge i had the following add-on : Volume master, which turns the volume up to 600%, however it has a quite handy bug: whenever you change the volume with add-on and then try to full-screen the player, instead going full-screen, it becomes full width theater mode player. is there any such add-on for firefox?

adding images as an example.

I tried restore under managing bookmarks, but it only give me about a week or two's dates as choices. I went back and it is still gone. I looked for an Old Firefox Data file on my desktop (or anywhere on my computer) and did not find that either. If I can't choose to add something to a category or to the tool bar, the bookmark function is not really helpful to me.

How do I confirm that the AI that was recently put into the browser is not working? I want nothing to do with this technology, if it is not able to be disabled then I will switch browsers.

Hello, my name is Dimitris and I have pc with windows 11 and bitdefender total security installed and fully updated. Since yesterday when I open mozilla firefox a file on desktop appears with the name bd_config.cfg. I wonder whether my pc is infected with a virus or malware?

I use Firefox as my browser. I have 3 BT e-mail addresses. I wish to delete 2 of them. In the drop down menu to sign into my e-mails it lists my e-mail addresses several times How do I delete the entries I don't need

Firefox just did an update about 9 AM on 11/12/2025. I use dictation software to navigate the webpages due to disabilities with my hands. The software can no longer recognize any of the tabs at the top of the screen, nor any of the buttons on webpages. This makes it almost impossible for me to navigate on the web. Something must have gone wrong/been overlooked in your coding with this update. Can this please be fixed?

Hello

I want some help please. When I open links from viber or discord, the links open in a new firefox window not the one am using at the time and they open on a no firefox profile window. I don't know what do and how to make the links open in the right firefox window. Maybe you can help me somehow?

I've been having issues logging in to my Instagram account through the Firefox browser. I've tried entering the password manually, clearing cache+cookies, opening in troubleshoot mode, and turning off the enhanced tracking mode (in case that might've been causing the issue) all to no success. This has been an issue since I started using Firefox as my default browser about 2 months ago.

Since update to latest version of Firefox, I cannot access content on Facebook. All I get after long wait is the blank screen with the Facebook logo in the middle and Meta logo at the bottom. No problem before update. Other sites seem OK but take much longer to load. I can get Facebook with MS Edge. I'm using Windows 10 on PC.

Hello everyone. From a while now that I need to change to Google Chrome everytime I want to put my credit card details to buy something online. Simply because the text boxes in Firefox don't show. They're simply not there. There are very few websites where they show up for half a second and disappear right after. I've tried disabling "enhanced tracking protection", disabling all my plug-ins, changing the "hardware performance" option, cleaning cache and cookies. Nothing seems to work. I'm going crazy because I like firefox and I want to work always in this one browser, not changing each time I want to do a different task. Similar thing happens with some websites when they freeze before you explore them and the pop-up window comes asking you about the cookies. But some of these, the window disappears right away, so I can see the page but it's stuck, because I didn't manage to accept the cookies option

Please, can you advise me what can I do? It's getting very frustrating, I'm really considering moving everything to Chrome and I don't want to. Thank you.

Bellow you see an example of Firefox page and Chrome.
