I've been a Firefox user for a very long time with no real problems, but this one may force me to move to Chrome. Recently, I've noticed that some things show up or work in Chrome, but they don't work in Firefox. I've encountered this problem more recently and it seem to be getting worse. Just today, I had a problem with the V.A. and AMC theater websites. Is there a workaround to this problem. It's going to get bad if even the government is using google extensions.

I looked at the system requirements page at https://www.mozilla.org/en-US/firefox/141.0/system-requirements/ . For Windows devices, the operating systems supported are listed as "Windows 10 or later".

In October 2025, Microsoft officially stops providing feature and security updates for Windows 10. However, they offer consumers and businesses the option of enrolling in 1-year, 2-year, and 3-year subscriptions for Windows 10 devices which will provide another 1-year, 2-years, and 3-years of additional security updates. You can read more about this at https://learn.microsoft.com/en-us/windows/whats-new/extended-security-updates

For those individuals and businesses who will be enrolling devices into the Windows 10 ESU program, will Mozilla continue to support Firefox on Windows 10 after October 2025, at least for those receiving security updates through Microsoft subscriptions? Or at that point will Mozilla consider Windows 11 to be the only supported Windows operating system?

Thank you!

For the past 2 months I've found it very difficult to sign into my Hotmail account using Firefox. Microsoft keep telling me to use a VPN or another device. I like answering emails on my computer because of its large screen. I've tried signing in about 2000 times now. Firefox told me they can't help me because I'm not a Mozilla subscriber even though they own Firefox. Microsoft told me it's Mozilla's problem. Can anyone help me please. John in the Philippines.

I am on Linux Mint 21.2, and I just updated Firefox (141.0). Now, the bookmarks bar, toolbar, and the tabs (everything above the displayed page), as well as the menu, bookmarks menu, and sidebar, are in light mode even though I have dark mode set (They were dark before the update). I tried playing with the Dark Mode settings to no avail. My system is set to dark mode in general. Are others experiencing this? Is there some sort of fix?

its one request i want to ask, can you add WhatsApp Web Plus into Firefox plugins/addons?

or maybe the question is, how to add the extension that exists on chromium based browser to firefox based?

thanks

Hello team,

I tried searching for a solution for the problem I'm about to describe but unfortunately I wasn't able to move forward.

I am running Firefox 141.0 version on my Macbook M4 Pro. The refresh rate of the display is set to 120Hz, but I the scrolling and interaction in the browser feels like it's on standard 60Hz refresh rate. When I compare it to Safari/Chrome it's not as fluent as it should be.

Am I missing an existing option that could be changed or is it something available at the moment?

Thank you, Arsen

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?

Firefox has started redirecting to advertising pages after clicking on a link. Only on 1 site. The site loads but not quite correctly. Normally has information about movie ratings show up when you hover over pictures. Have to double click (double load) to get where you want. Does not do it with Edge. Used to work fine, just started.

I installed the 4 choice AI system and used it once and was impressed. At that very same site I wanted to highlite copy and paste but when I did the highlight was so faint as to be almost invisable . After some attempts and not wanting to lose that feature I deleted the AI via mouse right click. Realizing that was not the problem I have searched several times but cannot get any further thru settings and more tools to try to Reinstall that feature . Also the sparkle button never showed with the fisrt install. It originally appeared of its own accord . Will I get the choice again when I reboot .. ? hope you can help me thanks mike

Losing my mind on this one.

Have 2 Macs I use at home, both running FF 141.0 and Sequoia 15.5.

Use Reader for RSS and Airmail for eMail. Both have settings to allow links clicked in those programs to open browser tabs in background. Handy way of banging through newsletters and RSS feeds before shifting to browser.

One on Mac, that open in battleground setting on both apps works as it has for, oh, last several years. On the other Mac, a few days ago that open in background stopped working with Firefox. It does work properly on Chrome and Safari if I set them as default browser (and, as I mentioned above, on my other Mac).

I've tried resetting Firefox on this Mac using the troubleshooting menu and have also cleared the Firefox cache. I even tried resetting the launch database in that Mac, although the fact Chrome and Safari are working fine suggests the OS isn't the culprit.

I'm unaware of having changed any settings, but am aware that "idiot user" may be the issue.

Regardless of how this happened, any ideas how to sort this annoyance out? Thanks!

Roughly every 2 weeks I backup important files to a external hard drive.

One of the things I always backup is my Firefox profile. I have been doing this for years without any problems.

I 7zip my profile and copy it to the hard drive.

I tried to do this yesterday (July 25 2025), and was getting access denied messages for files in the profile. So I tried to simply copy the profile. Same thing access denied.

I cleared the history, used wise disk cleaner, rebooted my machine and tried again. Same thing access denied when trying to backup or copy the profile.

I am assuming that this is happening since 141 because I updated Firefox since the last time I backed up my profile, and never had a problem previously.

Could anyone have an idea what the problem is? Thank you for your time.

Hello! I saw that the Test day event had started. In Firefox Beta, I entered messaging-system-action.testday in about:config, put it on a string and set the value to testday as it said in the instructions. When I restarted Firefox, the welcome window did not appear and there was also no letter S next to the search as it should be. Please help!

Thanks for the answers!

My PC died and I could not boot from bootable flash drive.

I had been backing up the system with Acronis to a WD Passport.

I purchased a new computer, and when I did a restore, upon starting Firefox, I did not have my old bookmarks, which are many.

Aren't they stored in a backup? If so, how do I get them back. I'm sure that some of the bookmarks came over from Netscape Navigator.

Thanks,

Bob

There is no longer a 'search tabs' symbol at the top section of the Firefox browser page since I switched to the vertical sidebar for tabs and after searching for help the Mozilla suggestion of ctrl+B just tries to search bookmarks. Please can you help as I have many many tabs always open and use this symbol frequently. Thankyou
