Forum zgromaźeństwa Firefox

For those of us that do want to use AI for work performance enhancement purposes, I have a question and also a comment for the Development Team. Here is the scenario real quick. I use Mozilla Firefox as my trusted browser today and that means that I open other AI systems such as ChatGPT, Grok, Gemini, etc. within this browser and could at times be running multiple browser sessions at the same time. My question is, will the Mozilla new AI Features attempt to try and compete with my other chat sessions for data capture, response and participation if I keep portions or the whole system enabled? The last thing I need is Mozilla AI as the selected browser now interfering with my other work flow processes in anyway including just listening along which would significantly increase the amount of resources used to run the Mozilla AI in parallel with other AI systems on my computer. I have heavy work loads at times and am already experiencing browser delays in processing data (even when setting up separate project chats for specific tasks) because of too many added features within all of the AI systems like historical chat session quick links on the right side of the screen. That's a ton of data that ends up getting stored/cached, referenced and processed with each command executed. I don't mind using Mozilla AI within the browser for general personal surfing and Q&A purposes but I can see this potentially becoming a big issue for us creators working with large image data processing tasks in other AI systems via the Mozilla browser. I will unfortunately be turning all of these Mozilla AI features off to start because I am not sure there really is a clear separation path for resource allocations within the browser now keeping my experience fast and efficient. Most likely this will force me into using a different browser product for personal vs business until things are much clearer. Hoping to learn a little bit here and see that things like this are being taken into consideration, even if it is a product roadmap enhancement for release sometime in the near future. Thanks so much!

Hi,

I’ve recently noticed that after a Firefox update, the browser has become very slow and unresponsive whenever I open multiple tabs, around 5–10. Before this update, I could open many tabs without any noticeable lag.

Now, new tabs take a long time to load, scrolling within open tabs feels choppy, and sometimes Firefox freezes for a few seconds before responding again.

I’ve already tried restarting Firefox, disabling extensions one by one, and clearing the cache, but none of these steps have improved the performance. I’m using Windows 10 and the latest version of Firefox.

Could anyone suggest what settings or troubleshooting steps I can try to fix this slowdown?

About a month ago, firefox started requesting i use a "USB key" when logging into hotmail or ebay. i do not have a USB key and have not knowingly selected that as an option. how do i turn that off. i can work around it but its becoming more annoying and seems to be spreading to other secure websites.

Firefox has reset entirely.

All of my profiles, bookmarks and saved passwords have disappeared; only history from this session appears. When I look at "Sync" I see the tabs from one of the profiles in the "Tabs from other devices"... it looks like Firefox thinks I have signed in from a new device, but I haven't.

The "tabs from other devices" lists the tabs from one profile under the correct device name. I am hoping all of the profiles, bookmarks, passwords etc are in there still. How do I "reclaim" these profiles on my laptop?

Where is this information stored so that I can access it?

Normally, I use the FireFox browser to access my gmail.com email account to view my messages. I am not sure what changed, but now when I enter gmail.com on my FireFox browser, I am not getting any response. I do not get the gmail display where I would view my messages. Additionally, I am not getting any error messages, all I get is a blank screen.

Is there any advice you can provide to help me resolve this issue ??

Names of screen parts are not clearly known to everyone. The ribbon along the top with back button, and web address, lacks the symbol to access the pull down menu for bookmarks. A very convenient feature that seems to be lost. Spent a long time trying to find it last year on a different machine. Convoluted process. Now not finding it.

Today (February 25, 2026) I received an email notice, apparently from Mozilla Monitor, advising me that my "Email addresses, Partial credit card data, Passwords, and Phone numbers" had been exposed in a data breach at Canadian Tire. This email seemed legitimate (the sender was breach-alerts@mozilla.com), but since it gave me a link to login to Mozilla Monitor, my first concern was that this might be a phishing email and it would be dangerous to click on that link. Instead, I went through the Firefox settings to login to my Firefox account and from there, I checked what Monitor had reported. The Canadian Tire breach was not listed there. However, when I went to haveibeenpwned.com, the Canadian Tire breach was listed there. It showed that the breach occurred on October 25, 2025. So why was the breach not listed for me on Mozilla Monitor? And why would I have received an alert from Monitor 4 months after the breach? Was this breach alert notice actually a phishing scam perpetrated by someone using the information from haveibeenpwned.com as bait?

I sent another help request on this subject but that too seems to have gone AWOL so I am trying again.

My passwords are being randomly wiped from my PC yet again but this time, although they are still on my Google Pixel 7 phone, Sync is not working for passwords. Strangely however, tabs are being synced.

I have tried every suggestion that I have found but syncing is just not happening.

To re-cap:- Passwords are not being synced from phone to PC Tabs are being synced between phone and PC.

Any suggestions?

Moderator note: This question has been edited to add a link to the previous question.

When syncing my account between browsers on other computers Tab Groups do not sync. I have to rebuild Groups in each browser. Also the Groups do not sync. I would like to see colors, tabs and positions sync throughout all browsers.

With the "Drag & DropZones" mode of the "Selected Text Searchers" extension, one can highlight some text on the page and then "drag" it, whereupon a screen of defined search engines appear as an overlay on the page, allowing for "dropping" of the text on top of any of the search engines, initiating using that search engine to search for the highlighted text. This stops working after 148.0: the search engines overlay does not come up, replaced with only the non-working icon on the mouse cursor.

Hi Guys,

I have an issue. I noticed now that if i click on one of my 300 tabs of website tabs, it automatically goes to some domain reseller and removes the whole link / information on the link that shows which tag or data i had on that link in the tab. If that makes any sense?

I hadnt yet gone through renaming all the tabs when the website changed domainbs and now i am unable to as the minute the tab wakes up from beind discarded, instead of coming up as can not find website (at which point in the past i could just change the 2 characters to the right domain), it goes to the domain reseller and removes the whole link / data that it used to point to.

Anyone know of a way i can do change the links on a mass scale of all the tabs i have?

I've been using Firefox for a long time, but recently, browsing YouTube has become a nightmare. The newsfeed lags significantly and scrolling is not smooth at all. Interestingly, the same site works perfectly fine on Brave and Chrome. I've tried clearing the cache, but the stuttering persists. Please optimize the hardware acceleration and AV1 decoding for mobile devices. Hoping for a fix in the next update! Also sometimes YouTube videos don't play. But the same video plays in another browser on the same internet.

I use LastPass to store lengthy passwords and auto open websites. After the latest Firefox update (148) when I click to open a website, the entire LastPass vault page just flickers and returns to the same vault page.

I use siscom.net for my emails. The pointer doesn't seem to open the emails. It changes into a finger on a hand and doesn't trigger the opening of the emails. I'm using Windows 11.

My Policies.Json can only block 1000 websites. Nothing after the 1000th entry is blocked. Is there a way to remove this limit?

Firefox 150 on Windows

Thank you
