I'm using Firefox 124.0.2 (64 bit) on Windows, and every few days I get the error about using an older version of Firefox, with Exit or Create New Profile options. I then run "firefox -allow-downgrade" from the command prompt and everything works fine... for a few days, when it happens all over again. This only started happening a couple of weeks ago, but it's getting really annoying. How do I stop it (short of using something like Waterfox or Brave).

Dear Mozilla:

It is SAD that the OS I have will no longer be supported due to exploits.

Considering the # of exploits, backdoors, poor coding, etc., in the later Windows OS versions - 1 would truly think that supporting the older and MUCH more secure Windows OS's would be wise.

Yes, they have "holes", but overall much fewer than current OS's.

Plus, the bad actors are very busy exploiting 10 & 11 and pretty much have ignored the prior versions.

Question... what if a major exploit is found that affects all OS's from 11 down to unsupported?

Will Mozilla make sure to supply a patch to the unsupported due to the danger of the new & serious "hole" found?

I vote... it would be wise to maintain a small contingency of legacy developers to help those who cannot buy new systems or flat out HATE the UI & UX of the 10 & 11.

Makes sense?

something apparently got corrupted in firefox.. i tried running update and i keep getting failed to update.. i have refreshed.. i have uninstalled and reinstalled ...nothing. i am sure there is a folder or file somewhere that is corrupted and i cannnot find it. because even when i uninstall and reinstall fresh. all my bookmarks are there .. how to i start a TRUE NEW install??

This has been happening for months now, on multiple devices (I have tried at least 3 different devices), and on multiple networks.

I have read the articles in here, but they just want me to check network configuration which is exactly the same for all browsers.

If I restart firefox it starts working again.

How can I prevent it from breaking randomly? This is the only browser having issues, I'm almost positive is some bug and not a configuration thing, given that it happens under multiple circumstances and devices, while Edge and Chrome simply keep working just fine.

There is no consistent repro I can give, afaik it is just random, at some point Firefox just decides to stop working and I have to restart it. This disrupts my work and browsing activities as I can lose progress on input forms and similar actions.

I've had an ongoing issue with Firefox now for several months since upgrading to windows 11. When I try to copy text, or images, url's or anything really that is supposed to go to the clipboard, it copies a blank text with no data instead. I can copy text and images from other programs and even paste them into text fields on Firefox but I can't copy from Firefox to anything else and it's frustrating.

I recently got forced into upgrading Outlook in windows and hated it so I started using Thunderbird and surprisingly, I have the exact same issue there as well.

I have tried: Running Firefox in safe mode (Shift + Left Click) Resetting Firefox Switching Back to default themes Disabling hardware acceleration Updating to the latest Beta Build (v126) Running Firefox Developer edition

I really want to get this fixed and working, I don't want to have to switch to another browser =/.

I am autofilling an ELSA payment portal. Firefox autofills the payment information correctly. But the program will not recognize the autofilled information and doesn't let me process the payment. I then overwrite all my information and then it allows me to proceed with the payment. I have used the same procedure for years but as of this last week, the autofilled information is not recognized as I click the "Continue" button after the autofilled info is complete, and it won't work. The ELSA source (State of Wisconsin) person said it's a browser problem on my end. No. The online form autofills just fine. Can anyone help? Thanks. Jeff

Hello,

I have encountered a recurring issue specifically with Firefox where SVG images fail to display unless a pixel-defined height attribute is explicitly set. This behavior contrasts with other browsers, which handle SVG scaling seamlessly, typically adapting to the specified width or inheriting dimensions from parent elements.

During our website development, primarily through Elementor and leveraging Flexbox in a WordPress environment, this discrepancy becomes evident. The issue persists exclusively in Firefox, confirmed through extensive testing across various browsers and OS's with multiple SVG files and sites.

For diagnostic purposes, I recommend conducting controlled tests with SVG images embedded with our current setup. Set the SVGs to 100% width without defining their height and observe how they render in Firefox compared to other browsers. This should help ascertain whether the behavior in Firefox is anomalous.

I am assuming it may be with the way the markup of the SVG is rendered as it doesn't happen with all SVGs, however, other browsers appear to fix or override whatever is getting in the way from rendering...it is a strange issue.

I have included two images as an example. As you can see in the first image, the SVG isn't rendering (in Firefox) , but does render in Chrome/Safari. It only works when I define a height in px value on Firefox.

Please let me know if further information is required or if any specific steps need to be undertaken to address this issue.

Thank you.

https://tasmota.github.io/install/ This is an example of what i am tryingto achieve bit no matter on which site i am , i do not get to choose from ports and my devices and always faults out saying similar messages that the browser does not support web serial in one way or the other for any site doing similar task. error message is as shown in the image shared basically complains of browser not supporting web serial.

The latest version of firefox for MacOS 14.4.1 has broken the picture in picture function. When enabling PiP, the video window takes up almost the entire screen and doesn't remember the size i set it to, like it did in older versions of Firefox. Another issue is when im in fullscreen mode and enable PiP, the PiP window takes me to another 'desktop', whereas before it would simply overlay on top of my screen.

I have 3 laptops all running windows 10 or 11. These all share a docking station giving access to an extended display, keyboard etc. All laptops run fine with the docking station except for one issue with the newest laptop... The screen resolution, only on firefox on the one laptop, (everything else is fine) is completly out of whack. I have tried the zoom function but no luck. I have trawled the internet but all the solutions are from 10+ years ago and refer to different versions of firefox and windows. I am not a computer geek so please dumb down any advice.

remove ad blockers even though I already have removed them.

printer is not recognized as being online although my other devices don't have the problem. i use Firefox on all devices

Whenever I get a link whether in an email from a verified sender or from using a site like Amazon, clicking on a link always results in "Hmm. We’re having trouble finding that site." This has happened ever since loading the most recent version of Firefox (124.0.2) and it is very, very frustrating. What is causing this? Even in "safe" mode this occurs. Please rectify this situation. I do not want to have to change browsers after more than 20 years with Firefox.

when I search for a page after opening a tab. The page will load slowly then stop. I'll then have to hit enter again for the page the load. This does not happen with Chrome or Edge. Any ideas how to fix this frustrating issue. Thanks.

On the page listing passwords, it was possible to sort them by "Alerts".

In settings, there is an option to enable checking the vulnerable passwords: https://support.mozilla.org/en-US/kb/firefox-password-manager-alerts-breached-websites

On my other laptop using Firefox v121, the alerts are properly displayed. But on my second laptop using Firefox v124, the alerts are gone. I can't sort password by "Alerts", the option isn't there. Both laptops share the same Firefox account and have password synchronized between each other.

Obviously, I ticked the "Show alerts about passwords for breached websites" box in the settings but it looks like it does not nothing. I also checked in "about:config" and everything seems good.

Is this feature gone?

Dzień dobry, W mojej przeglądarce chciałabym skorzystać z czatu GPT, ale pojawia się komunikat, że żeby skorzystać muszę wyłączyć blokadę reklam. Szukałam takiego czegoś w ustawieniach i firefox support, ale nie znalazłam nic co by pomogło w wyłączeniu blokady reklam. Czy mógłby mi ktoś pomóc i pokierować jak mogłabym wyłączyć blokadę reklam? Jeśli tak, byłabym wdzięczna.

Proszę o szybką odpowiedź

Suddenly on my PC the icon of Firefox turned white on both desktop and taskbar. And whenever I try to open Firefox, it says, "The file or directory is corrupted and unreadable." And I didn't make any changes myself. So far it was fine. Now what can/should I do?

Hi,

We have an application where we do not want to share the session cookies between tabs. Is this possible? If above answer is yes, next we would like to filter out some cookies by name that should not be shared across tabs. Meaning, we want some cookies that can be shared across tabs and some should not be shared.

Thanks in advance
