Firefox created a folder "Old Firefox data" on my desktop which is impossible to delete. I am getting an error "Access denied" even when trying to delete it as administrator. How can I delete this folder?

Hello, could you please let me know if updating Firefox as suggested (version 128) will be compatible with my iMac OS X Version 10.9.5. Thank you very much. Kind regards AS.

I have a macbook air laptop (late 2010) and have been using the latest version of Firefox browser for browsing. It's one of the few browsers still available. Google is popping up with the message that my browser is no longer supported. Do you have any suggestions about a browser that may work (other than a new computer please)? Will Firefox be coming up with a new extended version that will work? Thanks!

On the newest firefox update on Windows PC My PDF reading has been not displaying PDFs correctly on Firefox I tested on other PDF views and they work as normal (All images are normally white with black text PDFs) Sometimes it displays nothing at all (as seen in Image 1) Some pages will display correctly but the rest won't (as seen in Image 2) Some pages will display text but strangely (as seen in Image 3) It does flash white sometimes while scrolling but it still doesn't show text

Got this error message on recent update and now Firefox doesn't work at all. Platform Version '131.0.3' is not compatible with minversion >= 131.0.2 maxversion <= 131.0.2

In the last update of Firefox, today, the updated firefox opened without some bookmarks that I had open in the last session and that I don't want to lose. I tried the recovery following your help (Recover user data missing after Firefox update) but without success. How can I recover lost bokmars? Note: This situation has happened more times and if I can't recover the bookmarks, I will have to give up Firefox, which I have been using for many years and stop recommending it.

Win 11 stopped working on my Lenoovo Yoga due to bitlocker key requirement that does not exist I'm in the process of installing Ubuntu during the installation something went wrong "system program problem detected" which stopped the installation

Hi James Your reply does not answer my question - "Could you please advise a work-around to allow me to continue to use Firefox V 94.0.1 reliably after 25 March 2025". Thank you. Also FYI, I indicated that I was continuing to use Firefox V 94.0.1 (64-bit) on Windows 7 Professional. This is because all versions later than 94.0.1 modified settings which had to be reset after an update. This was not necessary up to and including V 94.0.1 Cheers Graham Garden

Hi everyone

I used Refresh Firefox option and it created "Old Firefox Data" folder on my desktop.

Awesome stuff. Sadly I cant get rid of it, here is why:

1. At first it said that the folder is used by another program and I cant delete it because of that. Cool, I decided to uninstall Firefox and make a clean install, so I have space to delete the folder too.

2. Long story short, it didnt work. I removed Firefox and tried to delete that folder, but wait for it, yeah I cant because I need permission from MYSELF. Awesome stuff.

3. I decided to use safe mode, so I used run command to run msconfig and I changed it to boot in to safe mode. But wait for it! YES! Its bugged and I cant login in safe mode, because pin is useless and it doesnt give me option to use password, so after hour of various things I got back to my normal mode via CMD commands. THANK YOU MICROSOFT.

4. So now Im stuck with the lovely "Old Firefox Data" folder, which cant be removed normally, neither in safe mode and wait for it! NEITHER WITH ADMIN CMD, not even the takeown /f "Old Firefox Data" /r command. THANK YOU MOZILLA!

So is there someone knowledgeable enough to help me to get rid of that folder pretty please? Like really a lot please.

I know that typically mozilla does not put a low bound on advisories, and https://www.mozilla.org/en-US/security/advisories/mfsa2024-40/ is the advisory for vulnerabilities fixed in ESR 128.2. CVE-2024-8387 is listed here. yet the advisory for 115, https://www.mozilla.org/en-US/security/advisories/mfsa2024-41/ does not list this vulnerability. Was this something that was only impacting 128 (for the ESR builds) or is there a mistake that either 115.15 did patch it but it wasn't documented, or the patch has been missed and ESR 115 is still vulnerable?

Hello,

I would like to obtain the complete release history of Firefox ESR Portable, including:

The exact release date of each Firefox ESR Portable version. The corresponding Firefox ESR version number (e.g., 115.x ESR, 128.x ESR, 140.x ESR, etc.). Any available information regarding delays between the release of Firefox ESR by Mozilla and the release of Firefox ESR Portable.

Could you please provide a list of all Firefox ESR Portable releases along with their release dates, or direct me to an official source where this information can be found?

Thank you for your assistance.

A new version of the "List All Tabs" appeared on my toolbar today, shown on the left and hovered over in the attached screenshot (ignore the Malwarebytes extension icon). The old icon for this button was a chevron with approximately the same functionality. I was able to remove the old icon, but I'm unable to find a way to remove this one. Here is what I've tried so far:

• Like the old one, the Customize Toolbar feature is unable to remove it since it is grayed out.
• For a while, I was able to remove the old icon by going to about:config and setting browser.tabs.tabmanager.enabled to false. This solution does not work for the current and some recent versions of the button.
• I attempted to create a userChrome.css file (following all the steps according to this this website) and added the following string: #alltabs-button { display: none !important; }

None of these attempted fixes have removed the button following a browser restart. Is there a way to remove it? I have no need of a button that shows me what tabs I have open when I can simply look at my toolbar.

Firefox auto updated when I opened it today. Then when it opened, all that was on the screen was the menu (file edit view history bookmarks tools help), the "search or enter address" box, and in the upper right hand corner the words "private browsing" with the purple circle and eye eyeglasses icon. That's all. I have tried looking at my profile. It seems to still be there. This seems to be a problem with the Firefox software itself. I have re-downloaded the software three times, the last time I uninstalled Firefox from my laptop and totally reinstalled. Every time I get the same results. This almost blank screen. Let me be clear. There is no purple background, there is no Firefox icon, there are no tabs, there is no customized menu bar, there is no search box in the middle of the screen. I'm working on a Windows 10 laptop 64 bit. Please don't tell me to upgrade the Windows 11, the laptop won't take Windows 11. I get the same window whether I open the regular fire fox or the private browsing Firefox.

Hello:

When I signed into my computer this morning, a pop-up asked me if I wanted Firefox to update. I let it do that, and then a pop-up came up letting choose among some photos and art for a desktop background. It even let me upload a photo of mine. I chose one of yours, now I can't change to any other photo I have on my computer. Please help.

Thank you,

Hello all,

During clean-up of my laptop I noticed 31 language package files in C:\ProgramData\O949. File names look like: langpack-en-US@firefox.mozilla.org, and they all originate from 23-Jan-2017 so I guess they're very old files which might be relevant anymore. As these 10,058 files occupy 56 MB I'd like to remove them from my laptop.

Does anybody know if such task is wise, not harming current running FF v131.0.3?

I cannot login into a website because they complain that I have an old version of PHP. Is that already included in Firefox? I am using Firefox Vers. 143.0.4 on a MacBook Air with MacOS Big Sur, Vers. 11.7.10 Shall I go to the PHP website and download PHP?
