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.

After update to 141.0.3(64bit), sidebar comes with waste space, as pink area in attached image.

It didn't shows in these years I'm using FF, I want to remove it but keep sidebar exist, like it was before. Where can I adjust it ?


If it's needed to be exist, why not put it on top of Sidebar ?

Hello,

My previous Firefox account under the email m**********i@*****ail.com has been locked. The message says it was locked due to a returned confirmation email, but the email is working fine now — I’m currently receiving emails from Firefox.

I’m unable to log into the old account to resolve the issue or change the email. I have since created a new account (this one), but I would like to recover access to the original account if possible.

Could you please help me unlock it or advise on the next steps?

Thank you.

Hi hi, I just did a complete reset to factory settings of my laptop (MSI), and a wipe of my hard drives too. After reinstalling Firefox (literally the first thing I did after setting up windows), it runs more slowly than before the reset (even for a basic search on Google/Duckduckgo). I am also unable to load any pages under the domain discussions.unity.com : the page loads forever, it's impossible to click on anything (even the hovering styles don't work), and I get a banner at the top of the screen that says "This page is slowing down Firefox. To speed up your browser, stop this page.". Also the memory usage for this page skyrockets (gone up to 4000MB??). I've disabled the 2 extensions I have (Dark Reader and Adblock Plus), restarted Firefox, restarted the computer, cleared the cache, even turned off the mozilla syncing, nothing worked. Any idea on what could be happening here? It's the first time in using Firefox for over 15 years that I've seen this happened.

Thank you for your time and attention <3

I have two Mac systems, a 2018 Intel Mac Mini, and an M1 2020 MacBook Pro, both running Sonoma 14.7.6. On the Mac Mini, Firefox opens to the familar "Recommended Stories". On the MacBook Pro Firefox opens to a long list of items I'm not the least bit interested in. How do I get the MacBook Pro back to nothing but the "Recommended Stories"? I don't want/need NHL, NFL, NBA,Television, MLB, Pro Soccer, Education, Food, Health, Parenting, etc., etc., etc.

Roughly every 2 weeks I backup important files to a external hard drive.

One of the things I always backup is my Firefox profile. I have been doing this for years without any problems.

I 7zip my profile and copy it to the hard drive.

I tried to do this yesterday (July 25 2025), and was getting access denied messages for files in the profile. So I tried to simply copy the profile. Same thing access denied.

I cleared the history, used wise disk cleaner, rebooted my machine and tried again. Same thing access denied when trying to backup or copy the profile.

I am assuming that this is happening since 141 because I updated Firefox since the last time I backed up my profile, and never had a problem previously.

Could anyone have an idea what the problem is? Thank you for your time.

Hello team,

I tried searching for a solution for the problem I'm about to describe but unfortunately I wasn't able to move forward.

I am running Firefox 141.0 version on my Macbook M4 Pro. The refresh rate of the display is set to 120Hz, but I the scrolling and interaction in the browser feels like it's on standard 60Hz refresh rate. When I compare it to Safari/Chrome it's not as fluent as it should be.

Am I missing an existing option that could be changed or is it something available at the moment?

Thank you, Arsen
