Hi Mozilla Community,

I am running Firefox on Windows 11 and I'm encountering a strange issue regarding the UI updates.

The Issue: My Firefox browser updates automatically to the latest version. However, my Default Profile is visually stuck on the old UI design. It does not reflect the recent interface changes associated with the update.

The Troubleshooting Context:

• I have verified that the browser itself is technically updated (via Help > About Firefox).
• The strange part: I have other Firefox profiles on this same machine. When I launch those profiles, they correctly display the new, updated UI.
• This issue is isolated strictly to my main/default profile.

Has anyone experienced this mismatch where the version number is correct, but the UI fails to refresh on a specific profile? Is there a specific fix for this?

Thanks in advance for the help.

Hi, Windows 11, 32GB memory. Firefox crashes regularly when between 1.6 and 1.9 GB is consumed It happens when watching YouTube. What is the solution, please? Thank you.

When browsing on IMDb (see image attached) when I click on the "See All" button just above "Soundtrack" at the bottom of the image nothing happens. This should expand the list above it, in the case an actor's credits. I have NoScript 13.5.2 installed but all scripts are allowed here. I get this on all the IMDb pages.

Hello Our town had two unexpected electrical outages during severe thunderstorms a few days ago. When I reopened Firefox and tried to log on to my outlook account, I received the following message: UTC Date: 2026-01-10T07:45:12.961Z Client Id: 6ACCBE246D464180895379C1XXXXXXXXX Session Id: d6e32139-5adc-4e94-b1e6-ff2b299c8f50 Client Version: 20251212003.10 BootResult: 2152857611 Back Filled Errors: None err: NS_ERROR_FILE_CORRUPTED: esrc: Preboot et: ClientError estack: getItem@https://res.public.onecdn.static.microsoft/owamail/hashed-v1/scripts/owa.94868.m.b71f002c.js:1:21149 i@https://res.public.onecdn.static.microsoft/owamail/hashed-v1/scripts/owa.94868.m.b71f002c.js:7:141360 importExistingCache@https://res.public.onecdn.static.microsoft/owamail/hashed-v1/scripts/owa.94868.m.b71f002c.js:1:23004 946909/i/<@https://res.public.onecdn.static.microsoft/owamail/hashed-v1/scripts/owa.94868.m.b71f002c.js:7:151863 initialize@https://res.public.onecdn.static.microsoft/owamail/hashed-v1/scripts/owa.94868.m.b71f002c.js:1:21016

I can open my email logins in Chrome and Safari, but not in Firefox. In Firefox I can open all my previous Bookmarks, but not Outlook. Any advice gratefully received, thank you

Just updated my MacBook Air to Sequoia 15.7.3. Since that update, Foxfire will open, but when trying to open an article in Foxfire, Foxfire locks up and doesn't wan to shut down even with "force quit." What can I do?

CCleaner wiped out my bookmarks and their functionality. I have repaired, then uninstalled CCleaner. I have refreshed, uninstalled then reinstalled Firefox. I have logged in and out of Firefox. I have made an HTML file of bookmarks from another device in order to try to import them. Firefox bookmarks will not proceed to an upload stage. I went into setting to add the HTML of bookmarks and it said "this is not a bookmarks file." Well, Firefox made that HTML bookmarks file so I have no idea how that could be. Nothing I have tried has worked.

I have been dealing with an issue in Firefox on Windows 11 for several weeks now hoping for a fix soon but it has not come yet. When I am browsing on eBay, it will lock up and I have to identify the thread in Task Manger and kill it (just the runaway thread, not the entire program). I can then continue of eBay for a short time before it happens again. This only happens on eBay while just browsing, not bidding/buying. Is anyone else having this issue?

Hi. I've downloaded dictionaries and languages, the check spelling option is enabled in the browser settings. However, browser doesn't want to do it automatically. I have to manually enable it with RMB context menu (and re-select languages) for each website individually. Moreover, when the page refreshes, spell checking turning itself off again in RMB menu (but stays enabled in browser options).

  Is this really how it's supposed to work?

How can I remove the moving blue ball from the tab of a frequently used website? It's distracting and hopefully not symptomatic of a problem It appeared on this new computer/monitor, used to be an icon Thanks, --Laurie

Not sure how to proceed to get my bookmarks moved from my old laptop to my new one. I'm a mainframe guy and often get lost with these PCs. :-)

Thanks...

I've been extensively relying on the `Ctrl+Alt+X` shortcut to spin up the selected chatbot in the sidebar, but ever since I reset my pc (complete reset, cloud download of windows, clear all apps and files) and re-installed firefox, the keyboard shortcut isn't working for me anymore.

I installed firefox with chocolatey, upon noticing that the shortcut had stopped working, I tried to downgrade to v145, which didn't help either. So an uninstall and re-install later (this time manually downloading the installer exe), `Ctrl+Alt+X` still doesn't work. Although hovering over the chatbot's icon in the sidebar shows the shortcut in the tooltip.

More info: `choco uninstall firefox` created a backup of "Old Firefox Data" or something similar, could that have somehow persisted the malfunction across installs?

Any help would be appreciated! System: Windows 10 Pro Firefox: 146

So I recently reinstalled windows and noticed that if I select the option that asks me each time where a file should be saved before downloading it, the browser appears to begin downloading the file (I can see the .part file in the default folder) but the window that actually allows me to browse for a location in windows explorer never shows up and thus, I am not able to actually download the file. However, if I select the "pick a folder and everything will download to that folder" option, it downloads just fine. I'm wondering if there was a way to reinstall firefox but keep all if not most of my settings and tabs etc.

Bookmark sidebar is visible, but bookmarks are not visible. bookmark icon show but the bookmark name is not.

This occurred after the latest update.

This has now occurred on another computer. Now I have 2 with this problem

For some reason after an update I lost the ability to access my collections. I can add new pages to my collection but have no way to access them. The option to add it to my homepage is now gone.
