Hi!

I've had issues with Firefox now for quite a while and they only seem to be getting worse. Performance is really bad, it's lagging while browsing, especially infuriating when typing as the letters come out at a stuttering pace. I've tried disabling extensions one by one, I've tried troubleshoot mode and experienced no major difference.

If I can't solve this soon enough I won't be able to keep using Firefox, as the experience is so frustrating. And it would be a shame since I've come to like it quite much.

Thanks!

Well being an OAP I needed new laptop. Always used Firefox browser but finding it difficult to get restarted. Had to opt out of window s to even download. Apparently I can transmit(?) my existing passwords etc from one laptop to another is this correct? Only basic computer knowledge but trying hard !! Karen x

I've used Firefox for years, but recently Firefox is unusable on Mac OS 15.7.2 because it's hogging all the RAM over time. I get a spinning beachball on my MacBook Pro. I look at the RAM being used and it's even over what I have in the computer. I have and always keep Firefox updated to the latest version.

When I click on the URL bar, the entire URL is highlighted. Then, if I click the left arrow, it brings my cursor to the start of the URL. After it moves my cursor, it then prepends the URL with the protocol (https://, http://, etc). My cursor is now no longer on the left side, and I need to hit my left-arrow key several more times to reach the left side.

Here is a screen recording of the issue: https://youtu.be/JtoL88bqSB0

Ideally, it would bring my cursor to the left side of the protocol, or show the entire URL, with protocol, in the URL bar, so that it does not need to prepend it.

Try to setup Thunderbird POP3. Keeps asking for a primary password I never set. I do have a password for Mozilla Firefox, used to log-in and create this question. POP3 Yahoo has been real trouble since the MSFT update as of Novemeber/December 2025.

Good morning, I hope you are having a good day.

I have an account with CA FTB (to make my estimated tax payments) and an account with CA DMV (for DMV stuff like renewing drivers license).

The FTB account is https://webapp.ftb.ca.gov The DMV account is https://www.dmv.ca.gov

So, Firefox browser seems to think these two accounts are the same, and tries to use my FTB credentials for my DMV account.

It seems like the .ca.gov causes the browser to think they are the same account?

So, I would appreciate any insight on how to fix or work around this problem.

Thank you,

Kim

здравствуйте, а по какой причине меня выкинуло из аккаунта firefox и всех моих гугл аккаунтов, я нигде не завершал сессии и из аккаунта не выходил, я просто перезагрузил пк, но теперь приходится заново заходить во все аккаунты

In Firefox, I have audio and video autoplay blocked globally, and added an exception for one particular website (Discord). However, Discord now only autoplays videos once, but doesn't loop them as it should (they implemented GIFs as videos, but now they don't loop).

Of course this could be interpreted as a bug in Discord's web client. However, there shouldn't be a difference between a website that got an exception and autoplay being globally allowed. Therefore i suspect that there is a bug in firefox where some property, state, or hint is set differently depending on whether a page has been added to exceptions or autoplay is allowed globally.

Is there anything i can do to work around this? I really want an autoplay exception to actually work as expected (the website doesn't need to know that it's special)

I have had Firefox using autofill for credit card payments for years--just replace my iMac with a new Mac Mini, and the credit card info still pops up when I am making a payment, but it will not autofill.

Hi I have switched to Mozilla from Chrome as I can’t update latest OS for my Mac. I can only browse internet intermittently and just want to ask if there are any settings I need to change on Firefox? Thanks Aidan

As the title states, every time I restart my PC, Firefox deletes everything. Bookmarks, passwords, profiles, all of it. I'm really tired of having to hunt down backups and restoring/creating new profiles constantly. Is there any fix? I really like Firefox but if there isn't a fix I'll look into a different browser.

For several months now I am not longer able to use Firefox when signing into sites (Bank of America, ID me) that authenticate using a security device. I have refreshed firefox and turned off enhanced tracking protection for those sites - but no change. When I long in and get to the authentication stage I immediately get an error before using the device; then later when I refresh and use the device Firefox freezes and is unresponsive. It does not show "unresponsive" in Force Quit - but the only way to do anything is to quit firefox. I'm running Sonoma 14, the latest version of Firefox. This is a major problem - I'm using Firefox for security and now I have to go to another browser each time I want to securely sign in to a site.

Firefox has been using more RAM and CPU on my system recently, especially with only a few tabs open. Is this expected behavior, or are there specific settings, extensions, or configurations I should check to improve performance?

If I need to search the internet for a web page within the broser field it doesn't do anything - It just displays https://sant.sectiononi.com/?u9k0n5b3X7oED91q=OFwQNgMRNQkJAFRVLjswJihcQ1tSTVZbUlhKWllDXFlbV1QoLTwsUw5XRVkHTF Thanks Andy
