what have you done with the? "new" firefox since the last update and change, it crashes, it won't open websites and now it said prove you're not a robot and other miscellaneous things are going on? Can I go back one update? I dislike what you have done. Firefox has always been my first choice and not Chrome, I'm going to have to find another search engine.

I am not able to receive mail from a user sending me mail from a gmail.com account. I have communicated with my ISP Optonline.net and they state the there mail process "checks out" and the issue could be the browser I am using, Firefox. The last email I have from a gmail.com sender was 8/28/2025. I have asked two different gmail users the send me mail and have not received any of them. I have cleared the Firefox cache but that did not correct the issue. I come to you to figure this issue out and hopefully solve it. Thank you Richard Everett [email removed]@optonline.net [phone number removed]

I use the French Search Engine, Quant in place of google. It works well, normally. I have just found the following message;

"We detected unusual activity from your device or network.

Reasons may include:

   Rapid taps or clicks
   JavaScript disabled or not working
   Automated (bot) activity on your network (IP 96.241.216.175)
   Use of developer or inspection tools"

I don't know why this has occurred. No one else uses my laptop. How do I get rid of this message and access Quant?

Hi,

I use firefox nightly as my everyday driver for WEB. So far I was very satisfied with the performance and mostly with youtube videos and hardware decoding. I use a Nvidia 1060 (GP106) which supports VP09/AVC1/H265 decoding.

The problem started only recently after some updates of the Firefox when I noticed that VP09 isn't hardware accelerated anymore. They way I test is using the Windows 11 task manager/Performance/GPU/Video decode.

At the same time, the stable Firefox has no issues with VP09 HW decoding. The same is valid for any other browser I tested. So the problem is isolated to the nightly.

I downloaded and ran mozregression GUI which indeed showed me that some nightly version before the VP09 worked just fine. I tested using the dates option of the tool.

This is the push_log URL from my test.

Thanks in advance for your help

Hello!

I have Firefox in all my units and it has worked very well over the years. Until I activated Avast SecureLine VPN on my computer HP Microsoft 11.

When the computer is connected to wifi/internet and VPN is activated, the Firefoxprogram won´t start correct. It says I am offline. If I then turn VPN of and update the page it will work immediately. As soon the page start the update I can turn VPN on and it will work on every link and page.

What can I do to get rid of this problem?

I keep a lot of pinned tabs, and one of those is my gmail account. After I delete cookies, I go to that tab to sign back in, and it opens another tab, causing me to have to pin and move the second tab and then delete the original tab.

Sometimes I'm taken back to login even after I've just left gmail for checking messages. Sometimes I can click and hold the back button and reopen it on an already sign-in instance of gmail, but not when I clear cookies.

This doesn't happen for any other site, just gmail. How do I fix this, or is there no fix?

For the past few days, I haven't been able to use Google Lens for searches. Why? It used to work, and I haven't changed anything on my computer.

I read the support article about this problem: everything seems fine, Google is definitely my search engine... Can you tell me what I need to do to get it working again? Thank you

I visited major electronics store yesterday and the tech there, installed Firefox on my 3 month old computer, that I'd purchased there. He did this because I'd simply mentioned to him how I really miss having a simple way to "cut and paste" and edit items like I used to be able to do on my former computer, a Mac Pro. I now have an HP and Microsoft appears to rule almost everything! After I got home I was deeply disappointed to find that my Firefox program had not finished loading and was not completely installed! :( So, following the instructions - which I found somewhat difficult to follow - I'm not sure whether I downloaded or installed the real Firefox program or a 'clone!' I say this because, once I downloaded and signed up for Mozilla's Firefox app. and finished the process, there was a note prominently posted on Mozilla's Support page asking (or telling) me to "Download Firefox! Don't I already have Firefox!?? If so, why doesn't Mozilla or Firefox already know I do? Another thing is, the first problem I encountered after opening my computer, was noticing that Mozilla and Microsoft seemed to be 'fighting' over which one of them I would be signing my Firefox through. (??) That was most confusing to me, because I had been warned to not sign up through Microsoft if I wanted the easy editing options. However, at this point I'm not exactly sure with whom I signed Firefox up through or if it is truly the bonified Firefox or just a 'player.' The invitation in a bright blue box is still on the Firefox Support page saying, "Download Firefox." Perhaps after all that, I did not download it at all. How can I tell? Was it done with Microsoft or Mozilla? It appears to be Mozilla, but I'm not tech savvy enough to really know, and does it really matter, which one? I'm still not used to this computer and still have trouble finding my apps! Can someone help me with this?

Hey, I have recently installed Zen Browser because of a friend's suggestion. Although I really loved the fresh vibe of the Browser in comparison to what I was accustomed of which is Chrome. But after some initial hassle of setting up the browser I figured one thing that although I have a 100Hz external monitor and a 90Hz Panel on the Laptop the Webpages while scrolling it felt that it was somewhere 45-60Hz. I tried the UFO Test as well but there I was getting 100Hz but whenever I visited any website (say LinkedIn or even Youtube) the page seem very very laggy and it made me switch back to Chrome (Honestly I wanted to stay on Zen only) but the problem forced me to switch back. I understand that the browser is still in its Beta Phase but still the experience I had it was not good. Hope I can get some resolution and hop back to Zen as I really want to.

PS - I have tried all the fixes from reddit pages, Hardware Acceleration, Smooth Scrolling, etc. none works.

Firefox recently sent out its monthly newsletter (Oct '25) with all sorts of options that can be enabled on Firefox. I'm a computer illiterate & foolishly chose some of the options -- don't remember which nor know how to discover them.

Now javascript is no longer enabled on my MacBook Air (macOs Big Sur 11.7.10). I cannot access my protonmail account and many many other sites.

I've gone cross-eyed accessing "fixes" that are labelled "only for advanced users" & am bright enough to not even try.

Is there a simple fix (short of wiping my computer -- with data going back 11 years) that even I can do?

Why aren't pull-down menus, behaving consistently, on Firefox on a Late-2021 M1-Max Sequoia v15.2 laptop Mac ? [2]

They work, properly, in Troubleshooting Mode -- is it the fault of my browser-extensions ?

In past few days twitch on firefox browser started to act strange. Webpage loads without some elements, login window doesnt opens, streams load indefenetely. Tried to clear cash and cookies. Chrome doesnt have such problem.

In daily work tasks, I end up with a large number of windows and tabs open. I am wondering if this is not adding to my extremely slow recovery of frozen tabs and windows and MANY instances of "Non-Responsive" everyday. Firefox is set to allow multiple processes, naturally, but I'm looking for ways to ease the pain here. If I disable Multiple Processes in Firefox v138.0.1, will I have problems running, for example, 5 windows with a total of 30 tabs spread across those Windows? (God knows I don't wanna have to grow up and actually manage the things I open up for stuff.) In addition, I am running Canva, sometimes Paint 3D, and Office 2021 concurrently. An associated question........in this most recent Firefox, how do I run Multiple processes, but limit the number of them to 5, for example? There used to be a setting in Firefox to do that, but I can't find it. I'm working with Windows 11-v24H2 on a Dell Inspiron 17 with an Intel Core i7-8550U CPU (about 7 years old) and 16Gb of Ram.........and sometimes I fall asleep waiting for many tabs, windows, and instances of Office 2021 to come back to work (I'm thinking they signed a Union deal, and didn't tell me about it.).

This has been going on and getting progressively worse for about 3-4 months.

Advice? Suggestions? I'd be truly grateful for any ideas you got.

Hi,

I have been using Mozilla for decades. In the last few weeks, the browser is constantly crashing. I heard there were some large scale denial of service attacts on Mozilla and I feel like I am seeing the effects. My browser is upto date so that isn't the issue. Is there anything I can do? If it doesn't get better soon I will have to switch to Chrome or worse :-( YUK! I love you guys and really hope there is a solution.

I’ve noticed that Firefox consumes a lot of memory, especially when I have multiple tabs open. Sometimes, it slows down my entire system, and Task Manager shows Firefox using over 1GB of RAM even with just a few tabs. Other browsers like Chrome or Edge seem to handle memory better with the same number of tabs.

I’ve tried restarting Firefox, closing unused tabs, and disabling a few extensions, but the problem keeps coming back. I even checked techsquest.com for tips, but I’m still struggling. Are there specific settings, hidden features, or optimizations I can apply to reduce Firefox’s memory usage without sacrificing performance?

Here’s what I’ve already checked:

Firefox is updated to the latest version.

No unusual extensions running (just uBlock Origin and Dark Reader).

Hardware acceleration is enabled.

Any help would be appreciated—thanks in advance!
