Has Microsoft blocked Mozilla from access my hotmail.com Outlook account now that MS has bought out hotmail.com? I have Windows 11 on my PC and I can't reach my hotmail.com acct via Firefox browser, please advise. Thanks.

I have just upgraded to version 145 and the title bar has disappeared Even though I have the Title Bar option checked in the customize firefox panel. If I uncheck the title bar option and then check the title bar option, the title bar will appear, but when I close firefox and then restart firefox the title bar is gone.

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.

Hello there, today was released a new version of firefox. downloading it not only crashed my computer, it also removed all my history and bookmarks. is there any way to revert this?

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.

I have Windows 11 and just installed the latest Firefox update (145). But every time I try to open a site, the page crashes. I seem to be able to work in troubleshooting mode, but otherwise I'm dead in the water.

Is there any way to roll back to version 144?

Help!

Can Firefox do anything to recover all of the downloads I'd saved until I accidentally had CCleaner erase everything? I don't know what else was deleted, but getting them back would be a big help.

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.

Apologies in advance if I use terminology incorrectly.

I've had this strange but intermittent issue for a while (through multiple Firefox versions) where pages will take a long time to load. I haven't timed loads exactly but I can confidently say it's a minimum of 10 seconds. The problem with diagnosing this issue is it's very intermittent; I can go hours or on a rare occassion days without it happening (I think, maybe I've just not registered some of the times it's happened). I have yet to try disabling all addons because of this.

Random quirks about the issue:

• It only happens on navigation to a new domain (or to a domain from a new tab). Once a domain has loaded, I don't have an issue on said domain for a while.
• It isn't tab specific. I can open a new tab in the same window and they will both take the same amount of time to load, often finishing at the exact same time.
• While waiting for a page to load, I can open a Private Browsing window, paste the URL, and the page will load immediately without issue in the Private Browsing window. This does not affect the page being loaded in the main window.
• I believe it has occurred immediately after a system restart, thus I don't believe it is related to long-running sessions.

The addons I have that don't also run in Private Browsing are:

• Augmented Steam
• BetterTTV
• Enhancer for Youtube (I can't find the addon store link?)
• Firefox Multi-Account Containers
• PocketTube
• Return YouTube Dislike
• SponsorBlock
• The Camelizer
• Youtube High Definition

There was a Microsoft update to Windows 11 today. Immediately after that, Firefox keeps giving me message that cannot restore tab. I close tab and try to open Firefox again and again get message that cannot restore tab. How do I fix Firefox so it works again?

Hello! Thank you for taking the request!

My firefox browser crashes repeatedly at startup, only showing the crash report window instead of opening the browser. When starting the browser using troubleshoot mode, it crashes too, showing the same result. After uninstalling and re-enstalling the latest version, the exact same problem continues.

I've scanned for viruses and checked the computer RAM and neither seems to be the problem.

The latest submitted crash report ID is bp-0917ab7e-e656-42ff-aa92-40b8c0251112⁩

I'm really grateful for your help, and looking forward to your reply!

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.

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.

Enter (paste) the URL into the Firefox address bar → hit Enter (paste and go) → open in a new tab every time. I want this to open in the same tab. Firefox version 145.0

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?

How long do tab groups stay in the browser? The tab groups I create disappear from 'list all tabs' dropdown. I was unaware there was a time limit. Could you let me know if I am doing something wrong here or change the description to include a timeframe. Saying that I can reopen suggests I can always reopen (see help article quoted below). "You can Save and close group, which will save and close the group for you to be able to re-open from the List all tabs tab icon 2 icon on the tab bar (or the Fx137ListAllTabs toolbar icon, if you use vertical tabs). "

I have lost a number of groups, which is not ideal. I see two tab groups from last four days but no others. See screenshots.

Would love clarification of this, as it is so useful to keep sites in groups for later use.

Thnks

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?

Hey everyone, I’m working on my website, lewisestimating.com, and I’ve hit a wall. Everything looks fine in Chrome and Edge, but in Firefox some parts of the layout don’t show up right. Images are out of place and a few buttons aren’t behaving like they should.

I’ve tried clearing cache, disabling extensions, and testing in private mode, but it’s still the same. Has anyone had this happen when working on their own site? Any tips on what I should check or tools in Firefox that can help me figure this out?

Would really appreciate any advice or suggestions.

Hi, I recently visited what I thought was a valid website only to get bombarded with ransomware popups. They state that my McAfee account has expired, an account that I never had, and they insist that I click their link to repair it. It doesn't appear to be a hack or that it is currently mining any info from my account. Obviously, I know better than to click on the link ( one of which is: d3venj8hubcc73ch6bp0.texonnerro.co.in TROJAN VIRUS FOUND Click here to secure your data. There are 4 different messages but all have the same URL address). It's really just annoying at this point. Also, it is specific to my Firefox browser. I have no issues when I use MS Edge. I looked to see if I could uninstall Firefox but did not find any way to do that. I know I would lose all my settings, etc doing that, but if that's the only solution, then so be it. Any assistance you can provide will be greatly appreciated.

The attached image is one of the messages. They're using your logo to make it look authentic

Thank you.
