Firefox Community Forum

Hi Everyone,

I’m Harmandeep Singh Kandhari from India, A Health and Wellness Motivator and Now, Recently, my Mozilla Firefox browser has started using much more memory than usual, and multiple tabs cause noticeable slowdowns. I haven’t installed many new extensions. What steps can I take to identify the cause and optimize Firefox performance without resetting my entire browser profile? 🦊💻

Thanks, Harmandeep Singh Kandhari

I keep getting pr_connection_reset_error messages in Firefox version 148.0 64 bit. I have purchased the windows 10 OS with extended updates and am running version 22H2 os build 19045.6937 do you have any suggestions on fixing this problem? When I am in my gmail account and using Firefox and I need to do a password reset that is when I receive the above error message.

When I'm on my phone and signed into my Firefox I want to be able to send tabs to my desktop. I'll click the three dots on my Samsung 20fe, click share, and click send to device. My p.c. is listed and when i click on it, a box pop's up and says "tab sent. I don't know where it's going, but it's not making it to my desk top. I've tried logging out and logging back in. on both devises

I have enabled the option to open the previous windows and tabs. I had one window that I always closed last as it had a lot of groups that are important for my work, so it used to open every time I started Firefox. Sometimes, even if I closed the window by mistake without closing other windows, I was able to get it back by pressing ctrl+shift+n.

But yesterday, I might have closed it by mistake and when I pressed ctrl+shift+n , it didn't come back. I wasn't able to access my window and now it's all gone. I don't see anything in recently closed windows in history.

I need those tabs back as they are very important for my work. they were a lot of tabs. I had many groups but now all are gone. I tried by using the previous.jsonlz4 in the sessionstore-backup by renaming it in the default-release profile as sesstionstore.jsonlz4 but still wasn't able to access my window.

I didn't clear my history as the tabs opened in the window still show up in the history.

Kindly help as soon as possible

Hello,

I am running windows 10, firefox 148.0.2 (64-bit) and when signing onto amazon.com I am greeted by this annoying pop up. Screenshot attached,

"Windows Security Making sure it's you

Please sing in to amazon.com This request comes from Firefox, published by Mozilla Corporation"

I do not find a need for this pop up and would like to know how to disable it. If you know how, please let me know!

FF is offering up possible login names for a particular site I have used previously even though I have removed all related browsing history, form data, and cookies (and cleared the cache). What am I missing? Is it using stored history for unrelated sites to guess at a user name, or is there some other hidden history I need to clear?

The five Firefox relay have not been used by me; can I create new ones. I don't use shopify or pinterest. It looks like they were set up in 2024. Can I receive 5 more to clean these out. Thanks.

Hello, Firefox. So I have this feature whenever I type. When I type my first letter, it is capital, and whenever I add an comma to my sentence and hit the space key, it adds an period. I don't remember enabling that feature, and I want to disable that feature. Is there any way if I can disable that feature? Thanks in advance!

I have a small usability suggestion regarding browser password managers.

When a website changes its domain (for example, from example-old.com to example-new.com), existing saved login entries keep the old domain. In many browsers, users cannot edit the domain field of the saved login.

As a result, users must delete the existing password and create a new one, which is inconvenient when managing many accounts.

A simple improvement would be to allow editing the domain/URL field of an existing saved login entry.

Example: example-old.com → example-new.com

Instead of deleting the login, users could just update the domain.

It’s a small feature, but it would significantly improve password management usability.

Thanks for your work on building great products.

Not sure if "browse" is the correct topic but here we go:

After a random crash (I don't remember the details, been a while) I've "refreshed" Firefox. Following that I started to have some problems with Google Meet. Haven't had any for years and suddenly when i open Google Meet (working from home and using Google Meet as an online meeting platform daily), everything becomes unresponsive. I can't change tab, cannot close Firefox from the close button, nothing. I open the Windows Task Manager and End Task manually to close the window so I can restart the browser. After restarting Firefox and launch Google Meet, it doesn't crash.

The other problem is when I try to watch something on Netflix, I hear the sound, see the subtitles but the video content is not present. It's just black screen with UI on it. Yes, I checked the DRM setting and no, other streaming services that I use don't have this problem. I can bypass this by launching Firefox in troubleshoot mode but I want to use my extensions. I even tried to enable them one-by-one to see if anyone causing problems but even when I disable all of my extensions like in the troubleshoot mode I'm still having the same problem.

I tried several solutions that I found on reddit etc. but nothing worked so far. I also re-installed Firefox and nothing changed.

Please help me before I lose my mind (:
