Firefox Support Forum

In order to mitigate supply chain attacks it would be useful to have a checksum published so that we can verify the file has downloaded appropriately. This should be included within the release notes.

We can't download a file from GOOGLE DRIVE on Firefox and Firefox Nightly but we can download on GOOGLE CHROME. PLEASE SOLVE THIS PROBLEM ! ! ! Our firefox version is 87 and 88(Latest now). Also SOME EXTENSIONS are seeing LAGly.

Have tried repeatedly to download firefox VPN - all I get is form to fill out with my info, which I do...and then a little red thing when I try to click on the submit button....have tried several times, same result... goes nowhere.

Since I am unable to find any forum dedicated to add-ons I'll post my question here and hope for the best. How do I transfer my FVD Speed Dial cells in my old laptop (win 7) to Firefox in my new laptop (win 10). Please don't tell me I'm going to have to redo each one by hand. I did check the Export button on Speed Dial but it doesn't transfer the custom pictures. Is there an easier way to do this? Like maybe moving a specific file(s)? Thank you - Sharon D.

Hello, I am on a MacBook Pro I was facing some issue with Firefox , which did not go even after refresh , so I decided to reinstall I used Appcleaner to uninstall Firefox , including the saved state and plist file.However , after uninstallation , I noticed there were some files under Library~Caches and Library~Application Support.I deleted these files by mistake . I would like to know if deleting these files would affect Firefox if I reinstall it Thanks in advance

When I turned on my computer this morning a message said I needed to download Firefox Update, so I clicked on that link. About a half hour later after it had also updated Windows 10 a page popped up telling me I had been sent a code to my email that I would need to input. I have not received an email or junk mail with any code. However, it looks like I already have Version 86. Please help me with this issue. I am so overwhelmed with computer issues I'm on the verge of tears right now. My last Windows 10 update Did NOT install and I am not the only one with this issue, but NO help from Microsoft. Did Mozilla update Windows 10 to accept the new version of Firefox? I looked at your educated guess, clicked on Show Details, nothing came up. Then I clicked on Troubleshooting Information and Share Data. I don't know if you are able to see this list or not, I don't know what 99% of it means, but I did copy a few things that may be helpful. environmentVariables": {

I already have VERSION 86 according to the information on Firefox. But the message I had this morning specifically asked to download FIREFOX latest version. Please help. Rhonda

I have no experience with having different browsers on the same computer and want to know if there are any conflicts or problems before I download a second browser.

Updating to new version of Fire Fox, my home page was changed to eco Start Page and my default search was a yahoo Eco Start Page . Why did this happen? I had trouble correcting this and how can this happen to FF? I thought your browser was secure.

there are no compatible versions of my add ons or extensions and i have lost a boat load of tabs i had saved and i want them back so i want to go back to the previous version of firefox...i now have the new 17.0 and not happy i lost all my info and settings

I have just upgraded to Firefox 17 and found that Norton 360 "Login Assistant" (formally named Identity Safe) no longer works. It does not fill in the username and password fields. It worked very well and did all the right things when I was using Firefox 16. There is probably a quick fix but in the meantime I have had to revert to version 16. Looking forward to the problem being resolved.

I live in Mountain View and use Google WiFi which is provided by Google for the City of Mountain View. For the past few months, they have been having a BIG problem with the corruption of downloads. Even teensy tiny ones. Perhaps you've heard about it since you're also in Mountain View. They have not responded to repeated posts from the forum... I have an iMac running Snow Leopard 10.6.8 and I haven't been able to update my software. I go to Lane Medical Library at Stanford to use the Windows machines there. I load whatever standalone software that I can onto a jump drive and install it at home. Unfortunately, some sites (like Apple and maybe even Mozilla!) recognize the computer you're on and only allow you to download software compatible with the machine that you are actually sitting at. This means that I can't reinstall Safari because I can't get a copy of it. And it looks like I might not be able to install Firefox 17.0 either. At least, that's what I'm trying to find out. "We've made some educated guesses about your current browser and operating system." See what I mean? So when I go to the library, will I be able to download a copy of Firefox 17.0 for the Mac and install it on my computer at home? Thanks!

After updating from 16 to 17 some of the extensions that are crucial for me stopped working, got disabled and got listed as incompatible with 17.0. Now when I try to toggle the extensions.checkCompatibility.17.0 boolean into the “false” position, it readjusts itself into “true” after each restart, making it impossible to force those extensions as compatible.

Why is this happening and what can I do to make it stay at “false”?
