Hi! I'm experiencing a strange issue with Firefox.

Every time I start Firefox, the site addons.mozilla.org opens automatically — and it opens in fullscreen mode (as if I pressed F11). Here's what I've tried so far:

I disabled all extensions, but the problem still persists.

I changed the homepage settings to a blank page and even other websites, but it doesn't help — addons.mozilla.org still opens.

The issue happens even after restarting the computer.

I haven't reinstalled Firefox yet — I’d like to understand what might be causing this first.

Any help or suggestions would be appreciated!

Dear Firefox Team,

It has re-occurred to my Firefox Browser of the latest version of 115.28 with some websites which I have recently visited however which have appeared 8 grids of blank or white pages again under "Recent Activity" as attached with the image for your technical troubleshooting suggestion.

Those 8 grids of Recent Activity in the older version of Firefox browsers used to have shown colorful graphics or images representative of the recent websites I visited in the recent past.

May I know what I am supposed to do to recover those graphics or images?

Kindly offer any suggestion or solution?

Thank you for your kind attention.

I'm not able to uninstall PWA apps created in Firefox 143.0.1 using Windows 11 usual uninstalling procedure. If i click "uninstall" in Windows Start Menu the app remains installed. PWA apps created with Firefox do not show on Windows 11 installed apps list so I cannot uninstall them. I haven't found any guide on the web on how to uninstall PWA created from Firefox. So, how can I effectively uninstall those PWA apps? Thank you in advance for your kind answer. Regards.

In the New Tab Home Page weather widget does not detect current location, and when I try to search any location from my Country Pakistan, it does not detect any city location.

Hello, I imported Bookmarks when I came to Firefox from a previous browser. The experience was terrible and challenges still linger. Firefox has come a long way, however UX still seems to be a 2nd class citizen. Bookmarks now has somewhat duplicate directories and this in turn is causing desktop/phone sync doubt and is likely missing bookmarks.

When sync breaks, it is so confusing. How can I simply have a working Bookmarks sync on desktop/phone?

Perhaps there was a challenge when I need Bookmarks to appear in the top bar when a new Tab is opened, as this was contrary to default Firefox settings.

I just want to know WHERE the notifications land? I have a very old macbook pro (mid 2010) so I have a sneaking suspicion firefox is trying to tell me something about not being supported, yadayadayada, BUT where are the notifications? The OS am currently using is High Sierra 10.13.6 CAN ANYONE HELP ME OUT HERE? Sorry to be such a klutz but these banners appear every day and I can't seem to access whatever it is that firefox is trying to communicate. Thanks all!

Hi I have a firefox account which I use on 2 macs and a PC as well as an android phone. For the past few months non of my book marks, passwords etc are being synced across the system and I have now completely different book marks on different devises. I have synced each computer multiple times without effect. This used to work perfectly before I changed my password a few months back. It is now reaching a point that firefox is no longer usable for me?? Thanks for your help

I am used to having a Firefox for my personal Mozilla account, bookmarks and sessions, and Firefox Developer Edition to be logged in my work account, where I could use everything I need to work in a separate environment.

Recently I changed a job. Logged out past-job@mail.com from Firefox Developer Edition, logged in with present-job@mail.com and... I still can see old bookmarks.

- I cleared history and new bookmarks: nothing
- went to about:preferences#privacy and clear all the data: bookmarks still there
- tried Help > More troubleshooting information > Refresh Firefox…: all the same
- reinstalled firefox@developer-edition with brew: nah
- eventually, logged out from presetn-job@mail.com in Firefox Developer Edition and personal@mail.com in Firefox; uninstalled both, deleted everything related to "mozilla" and "firefox" was able to find in my system: unsuccessfully

The last thing I didn't try yet is burning my laptop in favor to a new one.

Where are those bookmarks? Why nothing is helping?

Hello. I have a question. When I scan a PDF file in Firefox, it opens in a new window. Why? I don't mind it opening in a new tab, so I would prefer it to open in a tab.

I've seen on this forum from April that people are having an issue with Firefox and Google Passkey. I'm trying to log into my gmail accounts and can't get passkey to work. It freezes the browser and I'm not sure why this hasn't been resolved. Mac updated to Tahoe recently and I was on Sequoia 15.7.x (not sure exactly. Still froze. Photos are to show what's happening and that I needed to Force Quit each time.

Every time I update my drivers for Nvidia it of course reloads the screens. This causes all the tabs in Firefox to become separated on the Windows 11 taskbar. In other words, it looks like I have a new firefox window open for each tab (which I'm assuming is how it works but it's hidden most of the time).

It's not a HUGE deal per se, but it is kind of annoying. I have to close then reopen Firefox.

Like seeekerman who initiated the now-closed discussion at: https://support.mozilla.org/en-US/questions/1433369, I have used Firefox since its first release. With one exception - open image in new tab - I never use tabs. I want all the usable vertical space I can get.

For some time, Firefox on Windows (Windows 11, FF 143.0.4) has been showing a tab bar under the menu items, and above the bar with the URL etc.

How can I hide this when the FF window has only one tab, which is almost all the time for me?

The solution provided to seeekerman in that discussion, on 2023-12-08, was to create a userChrome.css file with some special incantations. I tried this it did not work.

Hello, I wanted to create a script that doesn't allow me to disable a certain extension. For that I thought to locate the file in which the states of extensions are put. I searched online, and the answer appears to be that such file is available in extensions folder in my profile. However, I am unable to find extensions folder under my profile.

I would appreciate the help.

Hi, can the function mention above be remove or flag off somehow? For me watching icon is already enough. cause when hover the side of the website to navigate accidentally expand the sidebar and in some time is just expand many times probably due to a bug.

My father used my computer and synced all of his firefox “stuff”, i need to get rid of all of it.

I tried to log in, but came across a message that told me it would just merge with his stuff. I would like his bookmarks and passwords gone so that only mine occupy the browser.

Is there a reset?

Hi, I have been trying all day to get my Trend Micro program working on my Firefox browser, including Password manager. These programs work ok on MS Edge browser, but I can't get it to work on my Firefox browser
