Firefox Support Forum

Hello, I've installed Firefox twice in the last couple of days (Windows 10 - I think) and I continue to receive messages that say I need to install the latest version.

Do you issue updates daily, or is there something wrong with my Firefox installation or is it something else?

Thank you.

I am trying to access Oracle eBS instance but when I login to the page, I get a notification as shown in the image.

After installing the plug-in and restarting the browser, when I try to run the application, I get the same notification.

Due to repeated issues over a week, I uninstalled Firefox days ago. Tried to Reinstall it repeatedly on same device several times. It was working before..BUT it keeps showing its downloaded on Settings but Firefox download page keeps showing "DOWNLOAD" Tried several times. Not my computer. Nothing works to resolve it.. Windows 11..

It has been observed that when a user uses the Firefox browser and tries to download a DDD file, the file format is .pdf instead of .ddd. In the devtools, it was observed that the content-type is text/plain in the response to the request. I changed the content-type to application/octet-stream, but the error still persists

Hi! On the latest version Mozilla Firefox 125.0.1 when i download .docx files i get the message 'File not downloaded: Potential security risk.' I select Allow download and the file downloaded can't be opened.

Thanks!

Dear all,

We develop a system on D365 platform. On Chrome enviroment, I click the export option, it will download the excel file, I can open it on Excel. However, I click the export option on FireFox, it will download the excel file but I can't open it on Excel. When I use the notepad to open the file to see the content, I found the file become HTML content. I can see the file on web broswer. I don't know why the file content will be change HTML content when I use the Firefox to download it.

Please help....

I wish to install and use the Firefox browser on my old 64bit Windows 7 laptop.

I believe the last v115 will be the last Windows 7 compatible version of Firefox, if this is correct where can I find this or the correct version of Firefox to download and install on my Windows 7 laptop?

The Firefox website only seems to provide v119 now.

Thanks, Graham

I found that Firefox can automatically generate a QR code for each URL, which is a powerful and useful feature! I'd like to know if this QR code has an expiration date.

I recently migrated data from my old MacBook Pro to a new MacBook Air. I installed Firefox on my new computer as it did not migrate. It installed fine but will not launch. Please help.

WED 21FEB24 The urgent issue is that in the last few weeks, many web pages do not load content, just a grey or white screen. Some will load the header. I am the Executor for someone's estate, and I am having this trouble with some financial websites that I must access to do the job.

Its been many years since I upgraded anything. It might be that Macintosh Firefox 78.15.0 esr (64 bit) and Thunderbird 60.9.1 are the newest revs that work with OSX 10.11.6 El Capitan. I have a 2011 MacBookPro.

I don't like the changes in the user interface that Apple put into OSX after El Capitan. But I may be forced to upgrade. Too late in life to learn Linux.

Maybe the minimalist solution is to upgrade Firefox. But that may require upgrading OSX, and Apple has made it really hard to do that unless you go to the very newest. OTOH I don't know if the newer OSX will run on my 2011 MacBook Pro. If I clicked on "software update" in About This Mac, what would happen? would it just start doing it, or tell me about it first?

The last time I upgraded something, probably Thunderbird but maybe it was Firefox, I had to learn a complicated process to copy & save the User Profiles (they are in a hidden directory), and then install them into the new rev. I don't want to go through that again. I just want to run the dmg file.

There used to be a Mozilla web page with all the versions & you could download the dmg file you wanted.

If I still have problems, I would have to buy a much newer computer. A several year old MacBookPro. But I don't like the "new" disk formatting method Apple created. It saves space by not actually making copies of files, but uses a pointer to one copy. So there is a single point of failure, which makes copies pointless. I want to keep using OSX Extended (Journaled) and I would have to have the seller of the computer do that for me, before I used Migration Assistant to put my stuff on it. I also hate the welded-on hard drive; being able to pull the drive is the best "broken hardware" solution.

I don't recall if El Capitan has the "OSX Recovery" system or if that happened in a later rev.

I use SuperDuper to make a clone of my hard drive as a backup & archive. I wonder if I could connect a copy on an external drive and then startup using the external copy. Then I could upgrade Firefox and see if it works, then do the same for OSX if necessary, and Thunderbird.

Suggestions & how-to info needed. TIA

My update preference for Firefox is to download but I will install it. But it consistenly (over the last numerous updates) changes it to Automatic. I do not want Automatic updates. I want to control when it updates. I do not see this issue addressed anywhere. I have checked numerous times. Please help! My sincere thank you for your time and attention to my request for help. Sincerely, Nicolas

Ark extracted Version 119 files into /home/Downloads/Firefox/Firefox. I tried ./update from the BASH command line, but didn't know which argument(s) to add to that command. I'm hoping to update Firefox 78.14 ESR to a recent version, whether ESR or not. Thanks for your help.

Firefox detected a potential security threat and did not continue to noodlemagazine.com because this website requires a secure connection

Files will not download. The file is a rfa(revit) file. This is my second day using this web browser..

I have checked setting, to which I switched around to try and troubleshoot. This did not work. I ended up downloading another browser and the file downloaded no issue. Why is this happening? Ant help is greatly appreciated!

Hi,

I cannot download & installed any add-ons or themes. After clicking the install button, I always get a red bar saying "Download failed. Please check your connection.". This happens on Firefox, Firefox beta and Firefox nightly.

I did some googling and found similar posts from a few years ago. These seem to suggest I don't have the correct certificate used to verify extension signatures:

• https://support.mozilla.org/en-US/questions/1257997
• https://support.mozilla.org/bm/questions/1258023

I checked my certificates and I don't have anything from "Mozilla Corporation - signingca1.addons.mozilla.org" (there's a screenshot of this cert in the first forum link above), so I think this is indeed the issue? I've attached a screenshot of my cert list where the Mozilla cert should be.

Please note I am on an M3 Pro macbook pro. It's a work laptop and I thought maybe our network settings were interfering with things, but my previous work laptop (Intel) could install add-ons just fine.

Would appreciate some help!

P.S. I found a workaround where I copied over all extension JSON and XPI files from my old laptop. So I am using my previous extensions just fine but still cannot download any new ones. Also I don't have access to my old laptop anymore so can't copy over any new ones.

Hi jscher2000, I want to thank you for your advice concerning a problem I had downloading Firefox to my Windows 10 laptop. I tried to follow your advice but was not successful. In the end, I googled "what if Firefox doesn't install". It took me to a website, https://www.makeuseof.com/fix-firefox-not-installing-windows , which took me to an article entitled "8 Fixes to Try if Firefox Won't Install on Windows". I tried #1 and #2 without success. #3, Temporarily Disable Your Antivirus Software, worked. Firefox is up and running. Feel free to share this with anyone who has a similar problem. No guarantee that it will work, but its worth a try. Again, thank you. drzee1946
