Using the "re-open tab" function on a browser based discord instance changed a bunch of my settings, for one it turned on vertical tabs, added extra side bars to everything, and made every ui element animated. Ive figured out of how turn vertical tabs back off, and while I was writing this, I figured out where to turn off this stupid animated gizmo to select what I actually want, instead of directly bringing up my bookmarks/history. How do I stop a random website from overriding my settings in the future? If discord can do it through incompetence another website can surely do it maliciously and I really dont fancy this happening again. The "best" (and completely unrelated) I've found on how to undo this, let alone prevent it from happening again is pressing esc or f11 because of course everything these days has to drown in AI slop :/

When accessing important accounts on websites, like financial websites, I've always heard you should close your browser when you're done with the secure website. If you log on in a PRIVATE window and close the private window afterword but leave the main FireFox window open, is that the same thing? I think it is and the private window will delete any login or activity info as if you closed the browser, I just want to confirm with someone more knowledgeable before I make a bad assumption. It also seems to have the added benefit of deleting anything you might download and save elsewhere from the download folder so you don't have to delete it from the DL folder and then the recycle bin. Seems like it's good practice to use the private window this way. Again, just looking for a 2nd opinion.

Thanks,

Hello This evening as I was going to pay for a book on a site well known to me, I notice that I don’t see a lock to the left of the address. I read your page 'Mixed content blocking in Firefox' after seeing that its little French sister was not up to date and it seems that it is the version of Firefox installed tonight that is behind this big change. Even my bank’s site no longer shows padlocks and it’s destabilizing. Why such a change without explanation??? I only read information about the split view in the same tab (which seems very useful) but nothing about this disappearance of the lock... Can you confirm that it is indeed the version from tonight 27/03/2026 that made this change at first glance worrying.

Thank you in advance and have a good day.

Hi,

Microsoft and Google are part of Anthropic's Project Glasswing but Mozilla is not. I am concerned about Firefox security if Mozilla in not being included. What is your plan to participate? Do I need to switch browsers in the meantime? Please advise. Thanks.

Cheers

I am using a local library and it comes to me that I find some activities that occur whilst working on my daily tasks and wonder, I would really like to run a diagnosis in my tasks and activities and check if there are no spams running me dry.

Hi,

Why private window is the same as general window browse? It should be different, yesterday was different, when I created a new account, this new private window change it to the public window, are they any bugs? Can you fix it? Thanks.

Does Firefox "remember" any browser data from another Windows user account? I created a guest account for someone today and while I was browsing, I got redirected to a site called fy3 dot fit which had the fake captcha. I did not open the run box and did not paste any commands from it, so is the guest account compromised or do I need to nuke Windows and start again? I read on reddit that it's an infostealer but if Firefox does not remember the other user account's browser data, does that mean nothing would be stolen if I did run it?

I have received 3 system alerts, all from Mozilla Firefox (I use Firefox as my default browser). 1) System is infected!---click on d45n9f8ko90s738b610.gsx-protect.co.in 2) ZEUS.2020 Trojan detected--with same directed site 3) System Alert!---with same directed site.

I use McAfee as my security system. They recommend going to Firefox settings and disallowing random site connections. How do I get my system running again.

Latest McAfee scan shows 45 entries deleted and 2 browsers reset

There must be a way to turn off this popup off. This is REALLY annoying when it covers a password box and to remove it i must click outside it and I lose focus on the password box. If you must put he box there then at least leave the first part of the password box clear so I cab click on it and not have to click again to get the focus back.

I am looking for an addon which displays times in different locations. I find one, FoxClock, which initially seems to meet my need. However, although the developer says its safe, and it has a Recommended badge, text in the app description says "Access your data for all websites." This may be 'honest' but it seems to be honest at the level of a thief saying "I'm going to rob you." WHY would a clock app need access to my data for all websites? Why would a clock app displaying on my desktop, not my browser, need to access any info about my data for any website? Poor coding? Lazy coding? Dangerous coding? Is this only a result of less than nuanced messaging by the developer or Mozilla, by using a generic message, rather than one which accurately states the 'access' is only for specified installation needs? Or another understandable safe reason? I'd like an explanation, since it does call into question the degree of security offered by Mozilla.

I have picked up some bug(s) on my Firefox that I cannot figure out how to get rid of. With a Firefox ID I have warnings of 3 Trojan Virus detected, Virus detected, hard drive infected, secure data notice and system alert. I also got a warning that my McAfee protection had expired which is very strange. Since switching over in 2010 from Windows to Linux I have never had protection of any kind and unlike Windows have never had a single problem. In addition when I was using Windows the protection that I had was never McAfee. I suspect that these warnings are not from Firefox given the misprints, spelling errors and the poor English. It is likely phishing from some third world country. How do I get rid of this obvious garbage permanently? Many thanks! Kris

I am just burned out with Firefox and not sure why I should continue to use it instead of some fork or Chromium-based browser.

It seems like every update brings some new GenAI/LLM component that is auto-enabled and difficult to disable. I do not want GenAI/LLMs in my web browser. I have dropped nearly every other application or software that has forced it on me and included it in their product. I feel like I'm trying manage a Windows system having to follow blogs to debloat, restore privacy, and restore security. GenAI/LLMs shouldn't be in my web browser. And, they should be opt-in, not opt-out in some confusing mix of GUI and about:config madness. If GenAI/LLM is so great, then make it an extension or a fork then let those folks use it from there. Don't bake it into the web browser.

I continue to use Firefox for uBlock Origin but I guess that would be possible with a Firefox-fork. However, I am just tired of having to continuously manage my Firefox browser and battle websites that only support Chromium-based browsers. If Firefox actually seemed intent on improving security and privacy then I could find the motivation but this GenAI/LLM nonsense seems the point of no return.

On my Android phone, I've switched to a Chromium-based browser given the poor state of security and hardening for the vanilla Firefox. I keep IronFox on hand but it is just easier to surf the web with a Chromium-based browser due to many websites just working better. Why should I deal with the pain and frustration of limited Firefox support when Firefox isn't even keeping up with security hardening?

As for desktop, the Firefox browser just doesn't seem as snappy or stable as I would expect. Firefox for Linux is still not supported for Slack Huddles. How is it 2026 and Mozilla/Firefox are still not fully functional with one of the major business chat platforms? Yes, I know this primarily a Slack and AWS-Chime-SDK problem but it is also a Firefox problem because there isn't much that a user can do. I've tried to prod Slack and the AWS teams numerous times to support Firefox but they've just done nothing. I also see nothing being done by the Firefox team, too.

Another example is the EdgeSuite CDN. Nearly always they block my traffic when I use Firefox. Switch to a Chromium-based browser and EdgeSuite is much less likely to block me. This is fairly consistent for the retail and financial institutions I use.

As far as I am aware, many of the security concerns brought up by Madaidan in 2022 still hold true for Firefox today, especially for Android and Linux. If this is no longer true, then it might be good for the Firefox team to post a rebuttal or update clarifying the current state of Firefox. The average users such as myself only see the Madaidan blog post and have to take it at face value. https://madaidans-insecurities.github.io/firefox-chromium.html

Anyway, I don't see a way ahead for me and Firefox but maybe you can convince me. It just seems like Firefox and Mozilla have lost their way. They no longer seem focused on security and privacy. Instead they're forcing privacy, security, and system resource disasters onto their userbases, just like Microsoft, Google, and every one of the major tech firms. I just don't see why I should use, promote, and even support Firefox going into 2026.

Repeated error reports appearing in right hand side of desktop, "system Alert", Trojan detected" , Three viruses found" , etc. have not clicked any any of the buttons. I have taken two snapshot images, if of use?
